  1. Hydrogen infrastructure for the transport sector

    International Nuclear Information System (INIS)

    Agnolucci, Paolo

    2007-01-01

    The aim of this paper is to review the factors already discussed in the literature and identify gaps or issues which seem to require further debate in relation of the introduction of hydrogen in the transport sector. Studies in the academic and grey literature have analysed transport systems with a rather wide range of hydrogen penetration rates, utilisation of the infrastructure, hypotheses on the dynamics of the systems, capital costs of the infrastructure and hydrogen price. Most of the issues which could widen the debate in the literature are related to policy instruments. In particular, more attention should be paid to the policy instruments needed to foster co-ordination among stakeholders, persuade drivers to buy hydrogen vehicles despite the existence of a sparse infrastructure; guarantee investment in the early, possibly loss-making, retail stations and to foster financially sustainable government commitments. The effect of limited availability of hydrogen vehicle models on the penetration rates in the literature and the sensitivity of the hydrogen price to taxation from the government are other two issues deserving a more in-depth discussion.

  2. CO-2 reduction in the Danish transportation sector. Working paper 4: Cargo transport - road pricing system

    International Nuclear Information System (INIS)

    1997-03-01

    In this paper other financial control measures than fuel prices are considered for the transportation sector. The main effect discussed is that of the road pricing system. From the point of view of the CO 2 emission there could be introduced a registration tax for trucks over 4 tons as the higher transport expenditure would tend to reduce road transport demand. EU infrastructure tax directive however recommends taxes for trucks exceeding 12 tons. Road pricing will grow within the categories of lighter trucks but it is only a minor fraction of the total truck expenditure, taking into account fuel tax, weight tax and registration tax. Insurance cost is not included in these consideration. (EG) Prepared for Trafikministeriet. 22 refs

  3. Transport and environmental sustainability: An adapted SPE approach for modelling interactions between transport, infrastructure, economy and environment

    Energy Technology Data Exchange (ETDEWEB)

    Verhoef, Erik; Van den Bergh, Jeroen [Department of Spatial Economics, Faculty of Economics and Econometrics, Free University Amsterdam, Amsterdam (Netherlands)

    1994-05-01

    The present paper aims at shedding some light on the concept of `sustainable transport`. Within the context of a sustainable development, the consequences of interdependencies between transport, infrastructure, economy and environment for the formulation of optimal regulatory policies are investigated. The Spatial Price Equilibrium approach is adapted for the analysis of sustainable spatio-economic development, and for the evaluation of first-best and second-best regulatory policies on the issues at hand. The analysis demonstrates the need for integration of elements concerning economic structure, infrastructure, transportation, environment and space in one single analytical framework when considering questions on sustainability in relation to transport. 2 figs., 1 appendix, 10 refs.

  4. Transports: Price of a strategy; Transports: Le prix d'une strategie

    Energy Technology Data Exchange (ETDEWEB)

    Bonnafous, Alain [Commissariat General du Plan, Paris (France)

    2000-02-02

    This is a report of the Workshop 'Strategic orientations of the transport policy' presided by Alain Bonnafous. In France the State invests annually ten billion Francs in transport infrastructures of national or regional interest. It contributes by several billiard Francs to ensure the financial balance of the public operators of the sector. The results are disappointing from many points of view. It plunged SNCF into debts, delayed building top-priority infrastructure, impaired competition between railway and road transports, etc. These drawbacks are explainable largely by the transport policy. This document urges for a joint action of all public means. There two sections. The first, titled 'Elements of reflection and recommendations' contains a synthesis and two reports on tariffing and financing the transport infrastructures. The recommendation is argued to submit all the transport modes to the same fare-establishing principles. A more rational methodology would allow establishing a fair competition, discouraging the unprofitable investment and solving the traffic jamming problems. A second recommendation aims at braking the dividers between the financial circuits, i.e., to set an end to an irrational system by which projects though very gainful for community fail to find financing while others less profitable benefit of afforded resources. The transport effectiveness drives the global competitiveness and affects the employment level. Solely a policy able to manage coherently the financing, fare-establishment, fiscal matters, and regulation could offer it to this country at a reasonable price. The second section contains the reports concerning the competitiveness of public operators. It analyses their economic situation and urges at breaking the vicious circle of their plunging in over-debts. Indeed, it suggests another long term vision upon the financial elements of these establishments and risks they are exposed to.

  7. E-mobility: European Energy and Transport Policies at cross-roads. The challenge of infrastructure deployment

    International Nuclear Information System (INIS)

    Faure Schuyer, Aurelie

    2016-01-01

    European clean transport policy envisages the development of charging infrastructures for electric vehicles within a European e-mobility framework. After the downturns of the Volkswagen scandal and the prevailing low European carbon price, the EU is bringing forward car passenger transport electrification. This requires new business models based on inter-operability. In supporting the objective of deployment of 8 million electric vehicles in 2020 and ensuring e-mobility services throughout the European Union (EU), the European strategy for low-emission mobility reminds Member States of their obligation to install publicly accessible infrastructures for electric vehicles by the end of the decade, as defined in Directive 2014/94. The strategy points towards an extension beyond the 2020 horizon of low-emission policies not only in car transportation, but also in goods transport (lorries), in public passenger transport (buses), and international aviation. It comes in the context of two major policy downturns. First, the Volkswagen scandal last October 2015 put a blow on the European cars manufacturing industry, as much as on the EU's oversight role in car emissions standards. Second, the sustained low prevailing carbon price is signaling that no emission abatement is taking place in the EU carbon market (European Emission Trading Scheme) covering power plants and industrial facilities. In car passenger transport, emissions can indeed be abated with electric vehicle, if the underlying system from which electricity is drawn is de-carbonized. As part of the Clean Power Transport Package, the European Strategy for low-emission mobility leans upon the Directive 2014/94 on Alternative Fuels Infrastructure, which requires Member States to roll out an infrastructure connecting electric vehicles (EVs). However, it is not giving any additional requirements for natural gas vehicle nor hydrogen-based vehicles (fuel cells). Among all forms of low emission vehicles (EVs, Compressed

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2013-06-01

    Over the next four decades, global passenger and freight travel is expected to double over 2010 levels. In order to accommodate this growth, it is expected that the world will need to add nearly 25 million paved road lane-kilometres and 335 000 rail track kilometres. In addition, it is expected that between 45 000 square kilometres and 77 000 square kilometres of new parking spaces will be added to accommodate vehicle stock growth. These land transport infrastructure additions, when combined with operations, maintenance and repairs, are expected to cost as much as USD 45 trillion by 2050. This publication reports on the International Energy Agency’s (IEA) analysis of infrastructure requirements to support projected road and rail travel through 2050, using the IEA Mobility Model. It considers land transport infrastructure additions to support travel growth to 2050. It also considers potential savings if countries pursue “avoid and shift” policies: in this scenario, cumulative global land transport infrastructure spending could decrease as much as USD 20 trillion by 2050 over baseline projections.

    1992-02-01

    There are 122 commercial nuclear facilities from which spent nuclear fuel will be accepted by the Federal Waste Management System (FWMS). Since some facilities share common sites and some facilities are on adjacent sites, 76 sites were identified for the Near-Site Transportation Infrastructure (NSTI) project. The objective of the NSTI project was to identify the options available for transportation of spent-fuel casks from each of these commercial nuclear facility sites to the main transportation routes -- interstate highways, commercial rail lines and navigable waterways available for commercial use. The near-site transportation infrastructure from each site was assessed, based on observation of technical features identified during a survey of the routes and facilities plus data collected from referenced information sources. The potential for refurbishment of transportation facilities which are not currently operational was also assessed, as was the potential for establishing new transportation facilities

    Full Text Available The purpose of the article is to conduct a complex research of the state of transport structure of Ukraine and substantiate prospects of its development. The developed transport system and corresponding infrastructure are a guarantee of high level of the country’s development, increasing the level of its investing attractiveness. Moreover, transport infrastructure serves as a uniting factor in the process of integration. Thus, the main function of transport infrastructure is the formation of external conditions for the management of economic entities. It is determined that the development of a state directly depends on how efficiently it performs management in different spheres. First of all, it concerns transport infrastructure. Today, the global trends necessitate constant perfection of management of transport infrastructure, in particular, investment attraction. The state and development level of transport infrastructure is one of the most important factors of socio-economic development of both member states of the European Union and Ukraine. Transport infrastructure occupies a services market sector with a market share of 75%. And in the macroeconomic context, the share of transport infrastructure in the overall volume of gross domestic product of Ukraine is 7%. In the modern management conditions, a negative dynamics of transportation and its share in the gross domestic product of Ukraine are determined mostly by the influence of economic crisis processes and negative state of development of transport infrastructure of the country. For the evaluation of activities of transport of Ukraine, we used the main indicators of its performance as criteria. The main criteria of performance evaluation of transport are: the volume of cargo transportation, cargo turnover, the ratio of modes of transport in cargo transportation, the volume of passenger transportation, passenger turnover, the cost of transportation, the ratio of passenger and cargo

    Full Text Available The paper presents threat assessment of potential terrorist attacks to the transport infrastructure. The range of transportation infrastructure has spread and includes railway, inland waterways, road, maritime, air, intermodal transport infrastructure and intelligent transport systems (ITS. ITS service is the provision of an ITS application through a well-defined organisational and operational framework with the aim of contributing to the user safety, efficiency, comfort and/or to facilitate or support transport and travel operations. Terrorism means acts of violence committed by groups that view themselves as victimized by some notable historical wrong. Although these groups have no formal connection with governments, they usually have the financial and moral backing of sympathetic governments. Typically, they stage unexpected attacks on civilian targets, including transport infrastructure, with the aim of sowing fear and confusion. Based on the analyses, transportation infrastructure is potentially threatened with terrorism attacks, especially road and rail infrastructure (about 23 %, and to a smaller degree the maritime and air transport infrastructure (about 2 %. There were 90,3% of incidents involve land transport (74,5% – vehicles, 9,5% – buses, 6,3% - rail covered the 41-year period 1967-2007 in the USA. Legal steps to fight terrorism have been taken on the international level, furthermore, some institutions have been established for this purpose.

    Pricing policies play an important role in transport policy making. The results of pricing policy studies, however, are often debated. This report presents a literature overview of the price sensitivities of transport demand and the effects of transport pricing policies in passenger transport, freight transport and aviation. The study concludes that the demand for passenger and freight transport is typically inelastic; the relative price change is greater than the resulting change in transport demand. Fuel demand for cars, public transport demand and air travel demand are, however, relatively sensitive to price changes. Car use is relatively insensitive to price changes. The demand for road freight is, in contrast to what is often assumed, relatively sensitive to changes in total transport costs. Relatively little empirical evidence is available on the impacts of pricing policies on rail freight transport, shipping and aviation. [nl

  6. Infrastructure expenditures and costs. Practical guidelines to calculate total infrastructure costs for five modes of transport. Final report

    International Nuclear Information System (INIS)

    2005-11-01

    Transport infrastructures in general, and the Trans European Transport Network (TEN-T) in particular, play an important role in achieving the medium and long-term objectives of the European Union. In view of this, the Commission has recently adopted a revision of the guidelines for the TEN-T. The main consequences of this revision are the need for a better understanding of the investments made by the member states in the TEN-T and the need for ensuring optimal consistency in the reporting by the Members States of such investments. With Regulation number 1108/70 the Council of the European Communities introduced an accounting system for expenditure on infrastructure in respect of transport by rail, road and inland waterways. The purpose of this regulation is to introduce a standard and permanent accounting system for infrastructure expenditures. However maritime and aviation infrastructure were not included. Further, the need for an effective and easy to apply classification for infrastructure investments concerning all five transport modes was still pending. Therefore, DG TREN has commissioned ECORYS Transport and CE Delft to study the expenditures and costs of infrastructure, to propose an adequate classification of expenditures, and to propose a method for translating data on expenditures into data on costs. The objectives of the present study are threefold: To set out a classification of infrastructure expenditures, in order to increase knowledge of expenditures related to transport infrastructures. This classification should support a better understanding of fixed and variable infrastructure costs; To detail the various components of such expenditures for five modes of transportation, which would enable the monitoring of infrastructure expenditures and costs; and to set up a methodology to move from annual series of expenditures to costs, including fixed and variable elements.

    The demand for transport infrastructure investment is a latent issue for several countries, mainly for developing countries. However, investments in major logistics projects should be carefully evaluated, in order that their deployment induces development without endangering fiscal sustainability by excessive public indebtedness. Fiscal accounting practices used currently in the feasibility studies of transport infrastructures in Brazil are very limited, as they do not consider indirect and induced effects of the infrastructure investment in the fiscal evaluation. In addition, the corresponding influence area has not an established delimitation method. The aim of the present paper is to develop a model for calculating economic and fiscal impacts of transport infrastructure investment projects that includes the direct, indirect and induced effects within a reference area do be determined. First, different project assessment guides in Brazil and abroad are examined with a special focus on the assessment of economic and fiscal impacts of the projects. Based on the assessment experience and on the definition of the fiscal balance of an infrastructure project, the next step sets up a framework for the calculation of the impacts, using more simplified data.

    Full Text Available A typical feature of transport infrastructure projects is that they are expensive and take a long time to construct. Transport infrastructure financing has traditionally lain in the public domain. A tightening of many countries' budgets in recent times has led to an exploration of alternative resources for financing transport infrastructures. A variety of models and methods can be used in transport infrastructure project financing. The selection of the appropriate model should be done taking into account not only financial resources but also the distribution of construction and operating risks and the contractual relations between the stakeholders.

  10. Price Analysis of Railway Freight Transport under Marketing Mechanism

    Regarding the problems in the reform of the railway tariff system and the pricing of the transport, by means of assaying the influence of the price elasticity on the artifice used for price, this article proposed multiple regressive model which analyzed price elasticity quantitatively. This model conclude multi-factors which influences on the price elasticity, such as the averagely railway freight charge, the averagely freight haulage of proximate supersede transportation mode, the GDP per capita in the point of origin, and a series of dummy variable which can reflect the features of some productive and consume demesne. It can calculate the price elasticity of different classes in different domains, and predict the freight traffic volume on different rate levels. It can calculate confidence-level, and evaluate the relevance of each parameter to get rid of irrelevant or little relevant variables. It supplied a good theoretical basis for directing the pricing of transport enterprises in market economic conditions, which is suitable for railway freight, passenger traffic and other transportation manner as well. SPSS (Statistical Package for the Social Science) software was used to calculate and analysis the example. This article realized the calculation by HYFX system(Ministry of Railways fund).

    Directory of Open Access Journals (Sweden)

    Artyom Gennadyevich Isaev

    2015-09-01

    Full Text Available The author specifies an empirical framework of neoclassical growth model in order to examine impact of transport infrastructure on economic growth in Russian regions during period of 2000-2013. Two different effects of infrastructure are considered. First, infrastructure is viewed as part of region’s own production function. Second, infrastructure generates spillover effect on adjacent regions’ economic performance which can be negative or positive. Results imply that road infrastructure has a positive influence on regional growth, but sign of railroad infrastructure coefficient depends on whether or not congestion effect is considered. Negative spillover effect is shown to exist in the case of road infrastructure. This apparently means that rapid road infrastructure development in some regions moves mobile factors of production away from adjacent regions retarding their economic development. The spillover effect of railroad infrastructure is significant and negative again only if congestion effect is considered. The results of estimation for the Far East and Baikal Regions separately demonstrate no significant effect of both types of infrastructure for economic performance and negative spillover effect of road infrastructure

    Exposure to airborne biological hazards in an ever expanding urban transport infrastructure and highly diverse mobile population is of growing concern, in terms of both public health and biosecurity. The existing policies and practices on design, construction and operation of these infrastructures may have severe implications for airborne disease transmission, particularly, in the event of a pandemic or intentional release of biological of agents. This paper reviews existing knowledge on airborne disease transmission in different modes of transport, highlights the factors enhancing the vulnerability of transport infrastructures to airborne disease transmission, discusses the potential protection measures and identifies the research gaps in order to build a bioresilient transport infrastructure. The unification of security and public health research, inclusion of public health security concepts at the design and planning phase, and a holistic system approach involving all the stakeholders over the life cycle of transport infrastructure hold the key to mitigate the challenges posed by biological hazards in the twenty-first century transport infrastructure.

    The two phenomena of Peak Oil and Human-induced Climate Change both together and individually create an imperative for early action, with the need to address Climate Change limiting the range of options that can be used to address peak oil. Peak oil is often portrayed as a market phenomenon, as a period when demand will exceed supply. The imperative to respond to the issues resulting from Peak Oil and Climate Change requires that New Zealand must move from its current high energy use, high resource use, high cost, petroleum dependent, transport infrastructure, to a sustainable one. Because a country's energy profile will increasingly define its economic success, New Zealand needs also to move to a lower energy society to remain competitive with other countries. What will be New Zealand's successful transport energy of the future and how it may be best used are key considerations of our future sustainable transport system. Low energy, low material use and consequently low cost, will be the main criteria. This paper first identifies our current transport energy usage, and some of the risks of being slow to respond to change. The paper then questions the central tenants of the current New Zealand Land Transport Strategy (2008) that we move to bio-fuels and electric cars because this is not a low energy, low cost pathway. We advocate that instead of just coping with change, New Zealand uses the necessity to change as an opportunity to recast our transport infrastructure to greatly improve the economic success and liveability of our settlements to New Zealand's benefit. The second part of the paper outlines a transport infrastructure based around electricity, with a heavy emphasis on public transport use, but also with freight much more dependent on electrified rail. This second part discusses: the advantages that NZ has that will facilitate this transition, such as favourable urban forms; the energy needs and energy availability; the benefits and

    Whilst there is an urgent need for infrastructure investment in developing countries, there is a risk that poorly planned and built infrastructure will introduce new vulnerabilities. As climate change increases the magnitudes and frequency of natural hazard events, incidence of disruptive infrastructure failures are likely to become more frequent. Therefore, it is important that infrastructure planning and investment is underpinned by climate risk assessment that can inform adaptation planning. Tanzania's rapid economic growth is placing considerable strain on the country's transportation infrastructure (roads, railways, shipping and aviation); especially at the port of Dar es Salaam and its linking transport corridors. A growing number of natural hazard events, in particular flooding, are impacting the reliability of this already over-used network. Here we report on new methodology to analyse vulnerabilities and risks due to failures of key locations in the intermodal transport network of Tanzania, including strategic connectivity to neighboring countries. To perform the national-scale risk analysis we will utilize a system-of-systems methodology. The main components of this general risk assessment, when applied to transportation systems, include: (1) Assembling data on: spatially coherent extreme hazards and intermodal transportation networks; (2) Intersecting hazards with transport network models to initiate failure conditions that trigger failure propagation across interdependent networks; (3) Quantifying failure outcomes in terms of social impacts (customers/passengers disrupted) and/or macroeconomic consequences (across multiple sectors); and (4) Simulating, testing and collecting multiple failure scenarios to perform an exhaustive risk assessment in terms of probabilities and consequences. The methodology is being used to pinpoint vulnerability and reduce climate risks to transport infrastructure investments.

  18. Commercial Consolidation Model Applied to Transport Infrastructure

    Energy Technology Data Exchange (ETDEWEB)

    Guilherme de Aragão, J.J.; Santos Fontes Pereira, L. dos; Yamashita, Y.

    2016-07-01

    Since the 1990s, transport concessions, including public-private partnerships (PPPs), have been increasingly adopted by governments as an alternative for financing and operations in public investments, especially in transport infrastructure. The advantage pointed out by proponents of these models lies in merging the expertise and capital of the private sector to the public interest. Several arrangements are possible and have been employed in different cases. After the duration of the first PPP contracts in transportation, many authors have analyzed the success and failure factors of partnerships. The occurrence of failures in some stages of the process can greatly encumber the public administration, incurring losses to the fiscal responsibility of the competent bodies. This article aims to propose a new commercial consolidation model applied to transport infrastructure to ensure fiscal sustainability and overcome the weaknesses of current models. Initially, a systematic review of the literature covering studies on transport concessions between 1990 and 2015 is offered, where the different approaches between various countries are compared and the critical success factors indicated in the studies are identified. In the subsequent part of the paper, an approach for the commercial consolidation of the infrastructure concessions is presented, where the concessionary is paid following a finalistic performance model, which includes the overall fiscal balance of regional growth. Finally, the papers analyses the usefulness of the model in coping with the critical success factors explained before. (Author)

    A space transportation infrastructure is described that utilizes propellant depot servicing platforms to support all foreseeable missions in the Earth-Moon vicinity and deep space out to Mars. The infrastructure utilizes current expendable launch vehicle (ELV) systems such as the Delta IV Heavy, Atlas V, and Falcon 9, for all crew, cargo, and propellant launches to orbit. Propellant launches are made to Low-Earth-Orbit (LEO) Depot and an Earth-Moon Lagrange Point 1 (L1) Depot to support a new reusable in-space transportation vehicles. The LEO Depot supports missions to Geosynchronous Earth Orbit (GEO) for satellite servicing and to L1 for L1 Depot missions. The L1 Depot supports Lunar, Earth-Sun L2 (ESL2), Asteroid and Mars Missions. New vehicle design concepts are presented that can be launched on current 5 meter diameter ELV systems. These new reusable vehicle concepts include a Crew Transfer Vehicle (CTV) for crew transportation between the LEO Depot, L1 Depot and missions beyond L1; a new reusable lunar lander for crew transportation between the L1 Depot and the lunar surface; and Mars orbital Depot are based on International Space Station (ISS) heritage hardware. Data provided includes the number of launches required for each mission utilizing current ELV systems (Delta IV Heavy or equivalent) and the approximate vehicle masses and propellant requirements. Also included is a discussion on affordability with ideas on technologies that could reduce the number of launches required and thoughts on how this infrastructure include competitive bidding for ELV flights and propellant services, developments of new reusable in-space vehicles and development of a multiuse infrastructure that can support many government and commercial missions simultaneously.

    2016-01-01

    Full Text Available More and more enterprises have begun to pay attention to their carbon footprint in the supply chain, of which transportation has become the second major source of carbon emissions. This paper aims to study both optimum pricing and order quantities, considering consumer demand and the selection of transportation modes by retailers, in terms of carbon emissions sensitivity and price sensitivity under the conditions of a cap-and-trade policy and uncertain market demand. Firstly, we analyze the effects of transportation mode (including transportation costs and transportation-induced carbon emissions, initial emissions allowances, carbon emissions trading price and consumer sensitivity to carbon emissions on the optimum decisions and profits of retailers. The results demonstrate that when consumers are less sensitive to price, the optimum retail price and the optimum order quantity of products are proportional to the transportation cost and transportation-induced carbon emissions of retailers per unit product, the carbon emissions trading price as well as consumer sensitivity to carbon emissions. However, when consumers are highly sensitive to price, the optimum order quantity of products is inversely proportional to the transportation costs and transportation-induced carbon emissions of retailers per unit product, the carbon emissions trading price and consumer sensitivity to carbon emissions. In addition, the optimum retail price of products is inversely proportional to consumer sensitivity to carbon emissions. We also find that retailers prefer a low-carbon transportation mode when the carbon emissions trading price is high. Meanwhile, the carbon emissions trading price influences the carbon emissions trading volume of retailers. These theoretical findings are further validated by some numerical analysis.

    The Danish Infrastructure Commission was appointed in November 2006 following a government decision. The terms of reference for the work of the commission state that 'the overall objective is for Denmark to maintain and develop its position as one of the countries in the world with the best transport systems, despite the fact that growing traffic volumes are increasing the requirements in the long term'. On this background, the commission has been given the following main tasks: 1) To analyse and assess the key challenges and development potential for the infrastructure and national traffic investments until 2030. 2) To identify and assess the strategic options and priorities and to put forward suggestions to strengthen the basis for the national investment decisions in the transport area. Furthermore, the commission was given the task of analysing and assessing proposals for strategies for handling a number of selected issues. These include the issue of cost-effective organisation and management of construction projects, the handling of preservation, climate and environmental concerns, the opportunity for better utilisation of the infrastructure by means of modern IT, and the significance of the long-term physical planning. The Danish Infrastructure Commission recommends six focus areas to be used as the starting point for planning the future transport system. Transport is about quality of life and prosperity - about connections between people, families and businesses. Infrastructure contributes to ensuring that we can get to work, and that products and goods can be transported to their destination in the shops and to the consumers. This makes infrastructure a vital cornerstone for our welfare and prosperity. Mobility is a key element in the competitiveness of businesses - and thus also for the growth conditions of Danish society. Efficient transport systems contribute to ensuring that goods can be produced in the best and least expensive location. The

    This study investigates the spatial price transmission among major wheat and rice markets of Pakistan using their monthly retail prices. For analysis Vector Error Correction Model and Co-integration approach were employed. Results showed that wheat and rice market prices are integrated. Some markets have positive or negative transmission shocks on each other due to the different geographical locations and transport infrastructure. All the wheat markets are adjusted to price changes in the long run equilibrium except few markets. Unidirectional and bidirectional causality exists between wheat and rice markets. Bad and poor infrastructure is a major impediment to price transmission among the markets. These market imperfections lead to food insecurity in the country. Government should formulate better policies and develop infrastructure towards better and efficient market function. The results of this study will help the policy makers to formulate a better policy to enhance marketing function to overcome food insecurity situation. (author)

    2013-01-01

    Quantification of emissions of greenhouse effect gases associated to transport infrastructures has been addressed in different ways. The first tools for this purpose appeared with the application of ISO 14040 standards (Life cycle analysis) that, applied to the particular case of energetic resources, led to a new concept known as carbon footprint. There is a specific standard for this quantification (ISO 14064) according to which, for the case of infrastructures, emissions and environmental effects linked to the whole life cycle are assessed taking into account all the stages: building, exploitation, maintenance and dismantling. the key point to perform this analysis is the accurate definition of a calculation methodology to be applied to the inventory of activities covered, in order to avoid information lacks, overlaps or redundancies. Quantification tools for emissions are effectively a reality, but social and political will, supported by strong economical reasons recognizing energy as a vital resource, is necessary for these tools to be developed, enhanced and used in a systematic way as a key decision element to choice among different transport alternatives.

    2018-03-01

    Sustainable infrastructure is the key to development success. At the same time, transportation infrastructure development will involve social and environmental conditions of the local surroundings. Assessment of the availability of such transport infrastructure is one of the solutions adapted from social and environmental impacts. By conducting a correlation test, the presence of transportation infrastructure and the social conditions of the environment can be identified. The results obtained show that the accessibility, the level of security, and the level of equality are correlated to social and environmental sustainability in Karawang. In terms of environment, the availability of transportation infrastructure is not directly related to the impact of environmental sustainability. The impact of the perceived environment also has no effect on the journey. Correlation results indicate that the length of travel time and congestion level do not make the perceived impact greater. The impact of the perceived environment is merely due to the high utilization of private vehicles in Karawang which subsequently leads to higher energy consumption.

    Full Text Available Weak transportation infrastructure in developing countries, e.g. Iran, presents abig obstacle to foreign direct investment attraction. One way of increasing theflow of foreign direct investment into a country is decreasing the production coststhrough expanding facilities as well as employing higher technology level. Thus,transportation cost usually is high in these countries and industries are oftenconcentrated in regions with more improved transportation system. The presentstudy aimed to investigate the effect of transportation infrastructure in Iran onforeign direct investment attraction. Hence, the researchers employed JohansenJuselius econometrics method to quantify the short run and long run effect oftransportation infrastructure, trade intensity, and market size on foreign directinvestment attraction during 1974-2007. The results emerging from the presentstudy indicated that transportationinfrastructure did not affect foreign directinvestment attraction in short run, but in long run, it had positive and significanteffect on foreign direct investment attraction.

    2014-12-01

    Recent events have demonstrated that the United States' transportation infrastructure is highly vulnerable to extreme weather events which will likely increase in the future. In light of the 60% shortfall of the $900 billion investment needed over the next five years to maintain this aging infrastructure, hardening of all infrastructures is unlikely. Alternative strategies are needed to ensure that critical aspects of the transportation network are maintained during climate extremes. Preliminary concepts around multi-tier service expectations of bridges and roads with reference to network capacity will be presented. Drawing from recent flooding events across the U.S., specific examples for roads/pavement will be used to illustrate impacts, disruptions, and trade-offs between performance during events and subsequent damage. This talk will also address policy and cultural norms within the civil engineering practice that will likely challenge the application of graceful failure pathways during extreme events.

  2. The Physics of Traffic Congestion and Road Pricing in Transportation Planning

    Science.gov (United States)

    Levinson, David

    2010-03-01

    This presentation develops congestion theory and congestion pricing theory from its micro- foundations, the interaction of two or more vehicles. Using game theory, with a two- player game it is shown that the emergence of congestion depends on the players' relative valuations of early arrival, late arrival, and journey delay. Congestion pricing can be used as a cooperation mechanism to minimize total costs (if returned to the players). The analysis is then extended to the case of the three- player game, which illustrates congestion as a negative externality imposed on players who do not themselves contribute to it. A multi-agent model of travelers competing to utilize a roadway in time and space is presented. To realize the spillover effect among travelers, N-player games are constructed in which the strategy set includes N+1 strategies. We solve the N-player game (for N = 7) and find Nash equilibria if they exist. This model is compared to the bottleneck model. The results of numerical simulation show that the two models yield identical results in terms of lowest total costs and marginal costs when a social optimum exists. Moving from temporal dynamics to spatial complexity, using consistent agent- based techniques, we model the decision-making processes of users and infrastructure owner/operators to explore the welfare consequence of price competition, capacity choice, and product differentiation on congested transportation networks. Component models include: (1) An agent-based travel demand model wherein each traveler has learning capabilities and unique characteristics (e.g. value of time); (2) Econometric facility provision cost models; and (3) Representations of road authorities making pricing and capacity decisions. Different from small-network equilibrium models in prior literature, this agent- based model is applicable to pricing and investment analyses on large complex networks. The subsequent economic analysis focuses on the source, evolution

    Tang, Amy; Chiara, Nicola; Taylor, John E.

    2012-01-01

    Renewable energy systems depend on large financial incentives to compete with conventional generation methods. Market-based incentives, including state-level REC markets and international carbon markets have been proposed as solutions to increase renewable energy investment. In this paper we introduce and formulate a carbon revenue bond, a financing tool to complement environmental credit markets to encourage renewable energy investment. To illustrate its use, we value the bond by predicting future revenue using stochastic processes after analyzing historical price data. Three illustrative examples are presented for renewable energy development in three different markets: Europe, Australia and New Jersey. Our findings reveal that the sale of a carbon revenue bond with a ten year maturity can finance a significant portion of a project's initial cost. - Highlights: ► Current financial incentives for renewable energy in the US are inadequate. ► We introduce and structure a “carbon revenue bond” as an innovative financing tool. ► Stochastic models of environmental credit prices are used to illustrate bond pricing. ► Three examples illustrate revenue bond impact on initial cost of infrastructure.

Methods calculation of the integral indicators of a particular industry development regression analysis method of the production function constructing. For regression analysis the paper uses panel data models with random and fixed effects and the pooled panel data model. To check the quality of the regression model the Fisher and Student ttests were used. To test the model for heteroskedastic properties tests by Park Glazer GoldfeldQuandt and White were applied. Results models of linear and logarithmic specifications with random and fixed effects were built as well as pooled panel data models. Significant coefficients of transport infrastructure indicators were obtained in both cases only in the pooled panel data models. The model which considered the railway density index as one of the characteristics of the transport infrastructure of the region showed the negative coefficient of this variable. Scientific novelty for the first time on the basis of Russian regions statistics using regression models of panel data the dependence has been studied between the level of transport development in the region and the dynamics of industrial production in it. As the characteristic of transport infrastructure development the specially designed integral indicator was used i.e. the transport enterprises and communications functioning in the region summarizing several characteristics of enterprises in the industry. Practical value the obtained results can be used to predict effects of adopting decisions on improving the transport infrastructure in the Russian Federation regions. The results and conclusion can serve as a basis for further research on this topic and be applied in the characterization of the Russian economy.

    The transport and storage activities of British Gas company are controlled by a distinct organization named Transco. The access charges paid by the suppliers for the use of Transco's network are regulated by a price cap since October 1, 1994. However, Ofgas, the office of gas supply which is the regulation authority in charge of the control of competition and of British Gas activities, considers this control system as inefficient and has chosen a RPI (retail price index)-X (expected productivity factor)-type price cap for the control of gas transport tariffs. This has led to a disagreement between Transco and Ofgas which has delayed the implementation of the new system up to February 1998. This article compares the choices made by Ofgas for the control of gas transport tariffs with the economical theory. It recalls first, the reasons why the price cap appears as more efficient than the service cost regulation, the alternate method used by regulation authorities to control the tariffs of natural monopolies. Then, the difficulties linked with the implementation of the price cap for the transport of natural gas in the UK are analyzed in order to explain the reasons that led Ofgas to change its formula. Finally, the bases of an optimum hybrid formula are proposed. (J.S.)

    This paper examines the price reversibility of OECD non-transport oil demand and its components: residual (heavy) fuel oil, non-transport distillates and other non-transport oil products. Our purpose is to determine the extent to which the reductions in demand following the oil price increases of the 1970s have been - and will be - reversed by the price cuts of the 1980s. The analysis is based on an econometric model which utilizes price decomposition methods to measure separately the effects of price increases and price decreases. These methods allow empirical testing of irreversibility and hysteresis, and should be applicable in other areas of economics where asymmetry of response or persistence of effect are evident. Based on the statistical evidence, we reject the conventional specification of demand being perfectly price reversible. We conclude that the response to the price cuts of the 1980s has been significantly smaller than to the price increases of the 1970s. Demand has followed a ratchet process: price increases reduced demand substantially when demanders conserved and switched away from oil, but price cuts did not reverse this process completely, if at all. This has important implications for projections of oil demand, especially under low price assumptions: the OECD's dependency on oil will not increase as much as some analysts may have feared. There is, however, another aspect of imperfect price reversibility: the possibilities of adjusting to future price rises may not be as great as they have been in the past. The easiest and least costly demand savings have already been made, and oil has been replaced by other energy sources in many uses: what's done is done. (author)

  11. A prospective analysis of Brazilian biofuel economy: Land use, infrastructure development and fuel pricing policies

    Science.gov (United States)

    Nunez Amortegui, Hector Mauricio

    country components, ethanol and gasoline are assumed to be perfect substitutes and combined in accordance with the specified blending regulations to generate VKT. For gasoline, an upward sloping supply function is assumed for the U.S., while in the case of Brazil a perfectly elastic supply function is used reflecting the pricing policy implemented in recent years. Consumers' driving behavior and fuel choice are determined by the model in accordance with the composition of the vehicle fleets in both countries. The model also simulates the economic impacts of transportation infrastructure developments in Brazil, specifically the recently launched ethanol pipeline project which is expected to affect not only the price, production, consumption and trade of ethanol but also the land use changes in the country. All these factors are combined to assess the impacts on economic surplus and total direct Greenhouse Gas (GHG) emissions in the U.S. and Brazil. The model is calibrated for 2007 and markets conditions are projected to 2022 under different policy scenarios. Empirical results show that a free ethanol trade regime in the U.S. would reduce the domestic ethanol production, including both corn and cellulosic ethanol. The U.S. biofuel production would be consumed completely in the domestic market and part of the demand is met by imports. Brazil, on the other hand, would meet its domestic ethanol demand and export about half of its production to the U.S., China and the ROW to meet the biofuel mandates in those countries. With regards to the land use, the model results show that intensifying the current livestock systems in Brazil would release a significant amount of land for corn and soybean production, and sugarcane acreage would expand in the denominated "region of expansion". The livestock semi-intensification in Brazil, driven by the high world ethanol demand and considered as the only alternative to expand sugarcane area in this study, would reduce the aggregate GHG

    This study examines the production costs of a range of transport fuels and energy carriers under varying crude oil price assumptions and technology market maturation levels. An engineering ''bottom-up'' approach is used to estimate the effect of the input cost of oil and of various technological assumptions on the finished price of these fuels. In total, the production costs of 20 fuels are examined for crude oil prices between USD 60 and USD 150 per barrel. Some fuel pathways can be competitive with oil as their production, transport and storage technology matures, and as oil price increases. Rising oil prices will offer new opportunities to switch to alternative fuels for transport, to diversify the energy mix of the transport sector, and to reduce the exposure of the whole system to price volatility and potential distuption of supply. In a time of uncertainty about the leading vehicle technology to decarbonize the transport sector, looking at the fuel cost brings key information to be considered to keep mobility affordable yet sustainable.

    Beyond the different approaches to set regulated prices for the use of infrastructure, a key parameter to determine regulated tariffs is the concept of asset life and how it changes with changes in the economic and regulatory context, which determines the optimal infrastructure investment and replacement policies. In this paper we look at the effects that changes in demand, the presence of substitutes and complements, the regulatory framework - both a pro or an anticompetitive framework -, scale economies, and the investment planning horizon, have on the economic service life of an asset and the tariffs for its use. We find that as the electric industry becomes more competitive, a negative effect on the economic service life of electric electricity transmission should be expected. Also, numerical experiments illustrate an inverse relation between scale economies on investment and the ESL of electricity transmission infrastructure. Further, we look at the biases on optimal investment that happen when optimal plans do not observe the life cycle of the investments and the ESL of the equipment, as well as the inconsistency and biases on optimal investment and replacement policies that might result when the Social Planner optimal investment plan lacks of a long-term commitment.

    2017-10-01

    To begin with, the identification and follow-up revitalisation of brownfields raises a burning issue in territorial planning as well as in construction engineering. This phenomenon occurs not only in the Czech Republic and Europe, but also world-wide experts conduct its careful investigation. These issues may be divided into several areas. First, it is identifying and cataloguing single territorial localities; next, it means a complex process of locality revitalisation. As a matter of fact, legislative framework represents a separate area, which is actually highly specific in individual countries in accordance with the existing law, norms and regulations (it concerns mainly territorial planning and territory segmentation into appropriate administrative units). Legislative base of the Czech Republic was analysed in an article at WMCAUS in 2016. The solution of individual identification and following cataloguing of brownfields is worked out by Form of Regional Studies within the Legislation of the Czech Republic. Due to huge the scale of issues to be tackled, their content is only loosely defined in regard to Building Act and its implementing regulations, e.g. examining the layout of future construction in the area, locating architecturally or otherwise interesting objects, transport or technical infrastructure management, tourism, socially excluded localities etc. Legislative base does not exist, there is no common method for identifying and cataloguing brownfields. Therefore, individual catalogue lists are subject to customer’s requirements. All the same, the relevant information which the database contains may be always examined. One of them is part about transport infrastructure. The information may be divided into three subareas - information on transport accessibility of the locality, information on the actual infrastructure in the locality and information on the transport accessibility of human resources.

  16. Trends in income and price elasticities of transport demand (1850–2010)

    Fouquet, Roger

    2012-01-01

    The purpose of this paper is to estimate trends in income and price elasticities and to offer insights for the future growth in transport use, with particular emphasis on the impact of energy and technological transitions. The results indicate that income and price elasticities of passenger transport demand in the United Kingdom were very large (3.1 and −1.5, respectively) in the mid-nineteenth century, and declined since then. In 2010, long run income and price elasticity of aggregate land transport demand were estimated to be 0.8 and −0.6. These trends suggest that future elasticities related to transport demand in developed economies may decline very gradually and, in developing economies, where elasticities are often larger, they will probably decline more rapidly as the economies develop. Because of the declining trends in elasticities, future energy and technological transitions are not likely to generate the growth rates in energy consumption that occurred following transitions in the nineteenth century. Nevertheless, energy and technological transitions, such as the car and the airplane, appear to have delayed and probably will delay declining trends in income and price elasticity of aggregate transport demand. - Highlights: ► Estimates trends in income and price elasticities of aggregate UK land transport demand (1850–2010). ► Income and price elasticities were very large in late 1800s and declined since then. ► In 2010, they were estimated to be 0.8 and −0.6. ► Future elasticities are likely to decline gradually in developed economies and faster in developing economies. ► Energy transitions may delay the decline in elasticities.

  17. Sensing Models and Sensor Network Architectures for Transport Infrastructure Monitoring in Smart Cities

    2015-04-01

    Transport infrastructure monitoring and analysis is one of the focus areas in the context of smart cities. With the growing number of people moving into densely populated urban metro areas, precise tracking of moving people and goods is the basis for profound decision-making and future planning. With the goal of defining optimal extensions and modifications to existing transport infrastructures, multi-modal transport has to be monitored and analysed. This process is performed on the basis of sensor networks that combine a variety of sensor models, types, and deployments within the area of interest. Multi-generation networks, consisting of a number of sensor types and versions, are causing further challenges for the integration and processing of sensor observations. These challenges are not getting any smaller with the development of the Internet of Things, which brings promising opportunities, but is currently stuck in a type of protocol war between big industry players from both the hardware and network infrastructure domain. In this paper, we will highlight how the OGC suite of standards, with the Sensor Web standards developed by the Sensor Web Enablement Initiative together with the latest developments by the Sensor Web for Internet of Things community can be applied to the monitoring and improvement of transport infrastructures. Sensor Web standards have been applied in the past to pure technical domains, but need to be broadened now in order to meet new challenges. Only cross domain approaches will allow to develop satisfying transport infrastructure approaches that take into account requirements coming form a variety of sectors such as tourism, administration, transport industry, emergency services, or private people. The goal is the development of interoperable components that can be easily integrated within data infrastructures and follow well defined information models to allow robust processing.

    Offer an alternative method to assess operational performance of companies in transport infrastructure of a region by making a comparison between transaction costs. The method is supposed to be a cross-functional and possibly applied to an analysis of economic entities of a different order (country, region, sector, companies) while evaluating “viscosity” / complexity of the outside and the inside. The paper includes an analysis of various methodological approaches to assess a development level of the transport infrastructure in a region. Within the author's approach and for purposed of the research, an index of transaction capacity or the transactionalness index is proposed, which determines a level of transaction costs calculated against the cost of production and revenue. The approach is piloted using the region-wise consolidated financial data of companies involved in the Russian transport infrastructure for 2005/2013. The proposed alternative way to measure corporate operating efficiency has proved its academic consistency. A specific comparison between the transaction costs using the transactionalness index allows first to identify companies or regions/sectors, where there is excess complexity of economical communication in bargaining. Secondly, the index does not only point out indirectly to a degree of development in the institutional environment, but also the infrastructure (the transport one in the example given). Third, the transactionalness level may say of uncertainty and risks. As an addition to theoretical and methodological aspects of transaction costs, the authors justify an approach to their size estimation, as well as their differentiation dividing them into two groups: those of a natural type and a background type. In a course of their discussion, the authors have concluded that there are such transaction costs in place, which are standard in a manner of speaking. There is a discussion whether it is scientifically reasonable to use an

    Developing countries around the world have developed innovative centre, or known as innovation hub, to meet the demand of today's changing global competitive environment. The shift of economic sector from manufacturing to services has allowed numerous regions and cities around the world to undergo major structural changes. In Malaysia, Skudai area is on its way of becoming a community-based innovation hub under the Johor State Economic Growth Strategic Plan called Johor Innovation Valley (JIV). Towards this new-city concept, land transportation infrastructure is among the most important network in being a linkage to the source of contribution in enhancing the local innovative environment. This paper highlights the requirement of land transportation infrastructure criteria that would be effective in making Skudai a community-based innovation hub. Data were collected through survey questionnaires involving stakeholders with the knowledge of land transportation infrastructure who also lives within the area. Descriptive analysis was employed with further rank breakdown using Average Index analysis. The findings distinguish the differences between each criteria of land transportation infrastructure. Change in traffic system, easier accessibility to one place to another and attraction to outside investor are among the impacts of growth of JIV. This paper concluded that selected requirement of land transportation infrastructure criteria is necessary for future contribution towards the growth of the JIV.

    The proposed study describes applying of neural network and fuzzy logic in transport control for safety improvement by evaluation of accidents’ risk by intelligent infrastructure devices. Risk evaluation is made by following multiple-criteria: danger, changeability and influence of changes for risk increasing. Neuro-fuzzy algorithms are described and proposed for task solution. The novelty of the proposed system is proved by deep analysis of known studies in the field. The structure of neuro-fuzzy system for risk evaluation and mathematical model is described in the paper. The simulation model of the intelligent devices for transport infrastructure is proposed to simulate different situations, assess the risks and propose the possible actions for infrastructure or vehicles to minimize the risk of possible accidents.

    This paper develops a simple model in which a regulated (upstream) transporter provides capacity to a marketer competing in output with an incumbent in the (downstream) gas commodity market. The equilibrium outcome of the firms' interaction in the downstream market is explicitly taken into account by the regulator when setting the transport charge. We consider various forms of competition in this market and derive the corresponding optimal transport charge policies. We then run simulations that allow us to perform a comparative welfare analysis of these transport infrastructure investment policies based on different assumptions about the intensity of the competition that prevails in the gas commodity market.

    Transport infrastructure elements are widespread and increasing in size and length in many countries, with the subsequent alteration of landscapes and wildlife communities. Nonetheless, their effects on habitat selection by raptors are still poorly understood. In this paper, we analyzed raptors' foraging habitat selection in response to conventional roads and high capacity motorways at the landscape scale, and compared their effects with those of other variables, such as habitat structure, food availability, and presence of potential interspecific competitors. We also analyzed whether the raptors' response towards infrastructure depends on the spatial scale of observation, comparing the attraction or avoidance behavior of the species at the landscape scale with the response of individuals observed in the proximity of the infrastructure. Based on ecological hypotheses for foraging habitat selection, we built generalized linear mixed models, selected the best models according to Akaike Information Criterion and assessed variable importance by Akaike weights. At the community level, the traffic volume was the most relevant variable in the landscape for foraging habitat selection. Abundance, richness, and diversity values reached their maximum at medium traffic volumes and decreased at highest traffic volumes. Individual species showed different degrees of tolerance toward traffic, from higher abundance in areas with high traffic values to avoidance of it. Medium-sized opportunistic raptors increased their abundance near the traffic infrastructures, large scavenger raptors avoided areas with higher traffic values, and other species showed no direct response to traffic but to the presence of prey. Finally, our cross-scale analysis revealed that the effect of transport infrastructures on the behavior of some species might be detectable only at a broad scale. Also, food availability may attract raptor species to risky areas such as motorways.

    2017-02-01

    Full Text Available Background: Freight transport infrastructure is an indispensable requirement for economic growth, development and prosperity. Public–private partnerships (PPPs, as a mechanism to fund and construct freight transport infrastructure, have been suggested by many in private and public sectors. Objectives: The concept of PPPs is dealt with, and the relevance of this mechanism is expanded upon. It is clear that PPPs in the rail environment present huge challenges and complexities. The objective was to determine whether PPPs are a viable mechanism to fund freight transport infrastructure in South Africa. Method: Experiences with rail PPPs worldwide have shown that many failures occurred implementing these. The challenges and complexities of PPPs, in the freight rail environment, are highlighted together with the benefits, risks and best practices of PPPs. It is shown that suitable policies, legislation and regulations concerning PPPs are in place in South Africa. Results: A proper framework and methodology to proceed should be in place. PPPs take time and are complex. Government involvement remains essential. Firm contractual agreements between parties are essential. Risk handling, risk sharing and the magnitude of risks should be clarified with agreement on where the risks reside. Financial viability, with value for money (VfM and financial benefits for private sector role players are non-negotiable. Conclusion: Appropriate legislation for implementing PPPs must be in place while two further important elements are economic circumstances and proper project execution. Taking all these factors into consideration, the freight transport sector can only benefit from successfully negotiated and implemented PPPs.

    2017-10-01

    The dialogue among the decision makers and stakeholders is a crucial part of any decision-making processes, particularly in case of integrated transportation planning and planning of green infrastructure where a multitude of actors is present. Although the theory of public participation is well-developed after several decades of research, there is still a lack of practical guidelines due to the specificity of public participation challenges. The paper presents a model of public participation for integrated transport and green infrastructure planning for international project TRANSGREEN covering the area of five European countries - Slovakia, Czech Republic, Austria, Hungary and Romania. The challenge of the project is to coordinate the efforts of public actors and NGOs in international environment in oftentimes precarious projects of transport infrastructure building and developing of green infrastructure. The project aims at developing and environmentally-friendly and safe international transport network. The proposed public participation procedure consists of five main steps - spread of information (passive), collection of information (consultation), intermediate discussion, engagement and partnership (empowerment). The initial spread of information is a process of communicating with the stakeholders, informing and educating them and it is based on their willingness to be informed. The methods used in this stage are public displays, newsletters or press releases. The second step of consultation is based on transacting the opinions of stakeholders to the decision makers. Pools, surveys, public hearings or written responses are examples of the multitude of ways to achieve this objective and the main principle of openness of stakeholders. The third step is intermediate discussion where all sides of are invited to a dialogue using the tools such as public meetings, workshops or urban walks. The fourth step is an engagement based on humble negotiation, arbitration and

    2017-06-01

    Full Text Available The relationship between transportation infrastructure investment and regional economic growth has been the focus of domestic and foreign academic research. Using the models of coupling degree and coupling coordination degree, this paper calculated the coupling degree and coupling coordination degree between the comprehensive level of transportation infrastructure investment and economic development in Hubei province and its 17 cities, and analyzed its temporal and spatial characteristics. The result showed that, from 2001 to 2013, the coupling and coupling coordination between transportation infrastructure investment and economic development in Hubei province were on a steady rise in the time sequence characteristics. It experienced the upgrade from the uncoordinated – nearly uncoordinated – barely coordinated – intermediately coordinated stages. In the year of 2013, the coupling and coupling coordination of transportation infrastructure investment and economic development in the 17 prefecture-level cities of Hubei Province showed a very uneven spatial difference. Good coordination, primary coordination, barely coordinate, and barely in-coordination are distributed in the province. The average coordination degree of the 17 prefecture-level cities in Hubei is relatively low, and there is a negative tend to expand the difference. This study has confirmed the relationship between transportation infrastructure investment and the economic development to be in an interactive coupling and coordination, but in different regions and different stages, the degree of coordination has obvious spatial and temporal differences.

  1. A Trial-and-Error Method with Autonomous Vehicle-to-Infrastructure Traffic Counts for Cordon-Based Congestion Pricing

    Directory of Open Access Journals (Sweden)

    Zhiyuan Liu

    2017-01-01

    Full Text Available This study proposes a practical trial-and-error method to solve the optimal toll design problem of cordon-based pricing, where only the traffic counts autonomously collected on the entry links of the pricing cordon are needed. With the fast development and adoption of vehicle-to-infrastructure (V2I facilities, it is very convenient to autonomously collect these data. Two practical properties of the cordon-based pricing are further considered in this article: the toll charge on each entry of one pricing cordon is identical; the total inbound flow to one cordon should be restricted in order to maintain the traffic conditions within the cordon area. Then, the stochastic user equilibrium (SUE with asymmetric link travel time functions is used to assess each feasible toll pattern. Based on a variational inequality (VI model for the optimal toll pattern, this study proposes a theoretically convergent trial-and-error method for the addressed problem, where only traffic counts data are needed. Finally, the proposed method is verified based on a numerical network example.

    Full Text Available Purpose: The paper concerns competition of different transportation modes coexist in inter-city transportation corridor. The purpose of this paper is to express the competitive relationship by building mathematical model and obtain the best sharing rate and the optimal ticket price of different transportation modes. Design/methodology/approach: Firstly, analyzing influencing factors of passenger choice about transportation modes, we designed an utility function of transportation modes. Secondly, referring to the game theory and logit modle, a non-cooperative game model between railway and highway was built. Finally, the model was applied to Nanchang-Jiujiang transportation corridor in China for an empirical analysis. Findings: The results indicate that the proposed non-cooperative game model is rational and reliable, and it supplies a scientific method to determine the optimal ticket price and passenger sharing rate of different transportation modes, and can be applied to the competition study on different transportation modes in inter-city transportation corridor. Originality/value: The main contribution of this paper is to built the non-cooperative game model, which can consider the needs of different travelers, and achieve reasonable passenger divergence of different transportation modes and coordinated development of whole transport market.

    This paper contains a tentative suggestion of how to take into account the value of changes in price volatility in real world cost-benefit analyses. Price volatility is an important aspect of security of supply which first of all concerns physical availability, but assuming that consumers are risk averse, security of supply can also be viewed as a matter of avoiding oscillations in consumption originating from volatile prices of for instance oil. When the government makes transport-related choices on behalf of the consumers, the effect on oscillations in general consumption should be included in the policy assessment taking into account the most significant correlations between prices of alternative fuels and between fuel prices and consumption in general. In the present paper, a method of valuing changes in price volatility based on portfolio theory is applied to some very simple transport-related examples. They indicate that including the value of changes in price volatility often makes very little difference to the results of cost-benefit analyses, but more work has to be done on quantifying, among other things, consumers' risk aversion and the background standard deviation in total consumption before firm conclusions can be drawn.

  10. Three essays on access pricing

    Science.gov (United States)

    Sydee, Ahmed Nasim

    In the first essay, a theoretical model is developed to determine the time path of optimal access price in the telecommunications industry. Determining the optimal access price is an important issue in the economics of telecommunications. Setting a high access price discourages potential entrants; a low access price, on the other hand, amounts to confiscation of private property because the infrastructure already built by the incumbent is sunk. Furthermore, a low access price does not give the incumbent incentives to maintain the current network and to invest in new infrastructures. Much of the existing literature on access pricing suffers either from the limitations of a static framework or from the assumption that all costs are avoidable. The telecommunications industry is subject to high stranded costs and, therefore, to address this issue a dynamic model is imperative. This essay presents a dynamic model of one-way access pricing in which the compensation involved in deregulatory taking is formalized and then analyzed. The short run adjustment after deregulatory taking has occurred is carried out and discussed. The long run equilibrium is also analyzed. A time path for the Ramsey price is shown as the correct dynamic price of access. In the second essay, a theoretical model is developed to determine the time path of optimal access price for an infrastructure that is characterized by congestion and lumpy investment. Much of the theoretical literature on access pricing of infrastructure prescribes that the access price be set at the marginal cost of the infrastructure. In proposing this rule of access pricing, the conventional analysis assumes that infrastructure investments are infinitely divisible so that it makes sense to talk about the marginal cost of investment. Often it is the case that investments in infrastructure are lumpy and can only be made in large chunks, and this renders the marginal cost concept meaningless. In this essay, we formalize a model of

    The paper addresses the use of general equilibrium models to analyze transportation policies. After a discussion of possible approaches, a representative set of static and dynamic models is developed and investigated, which focus on the interaction between general equilibrium, transport, infrastructure and environment. It is shown that each of these allows one to deal with specific types of policy questions. More technical modelling issues are dealt with as well, e.g. returns to scale, production functions, and disaggregation. Finally, attention is devoted to freight transport in a multisectoral production setting. 5 figs., 8 refs.

  13. Joint slot allocation and dynamic pricing of container sea–rail multimodal transportation

    Directory of Open Access Journals (Sweden)

    Di Liu

    2015-06-01

    Full Text Available The container sea–rail multimodal transport system faces complex challenges with demand uncertainties for joint slot allocation and dynamic pricing. The challenge is formulated as a two-stage optimal model based on revenue management (RM as actual slots sale of multi-node container sea–rail multimodal transport usually includes contract sale to large shippers and free sale to scattered shippers. First stage in the model utilizes an origin-destination control approach, formulated as a stochastic integer programming equation, to settle long-term slot allocation in the contract market and empty container allocation. Second stage in the model is formulated as a stochastic nonlinear programming equation to solve a multiproduct joint dynamic pricing and inventory control problem for price settling and slot allocation in each period of free market. Considering the random nature of demand, the methods of chance constrained programming and robust optimization are utilized to transform stochastic models into deterministic models. A numerical experiment is presented to verify the availability of models and solving methods. Results of considering uncertain/certain demand are compared, which show that the two-stage optimal strategy integrating slot allocation with dynamic pricing considering random demand is revealed to increase the revenue for multimodal transport operators (MTO while concurrently satisfying shippers' demand. Research resulting from this paper will contribute to the theory and practice of container sea–rail multimodal transport revenue management and provide a scientific decision-making tool for MTO.

    Merchant power plants are complicated with diverse risks. Of course where there are risks there are opportunities for reward. Creating an effective merchant plant requires a strong organization that is committed to marketing, trading and risk management. The organization must have the infrastructure to capitalize on the opportunities a merchant plant provides. The market dynamics are ever changing and move at incredible speeds--what was a moneymaking deal yesterday is no longer valid today. The merchant plant owner is the expert in setting up the actual infrastructure for trading the various commodities, including forward pricing, cash and physical trades, transportation and operation for maximizing the plant's potential. Optionally, the plant's risk profile and a risk management program are the key factors in determining the sucres of the merchant plant project

    Environmental impacts during the life cycle stages of transport infrastructure are substantial, including among other greenhouse gas (GHG) emissions, as well as resource and energy use. For transport infrastructure to be sustainable, such issues need to be integrated in the planning process. Environmental Impact Assessment (EIA) is required by the European Union (EU) in order to ensure that all environmental aspects are considered during planning of road infrastructure projects. As a part of this process, the European Commission has suggested the use of the tool life cycle assessment (LCA) for assessing life cycle energy use and GHG emissions. When analyzing life cycle impacts of the road infrastructure itself, it was shown that earthworks and materials used for the road construction have a big share in the total energy use and GHG emissions. Those aspects are largely determined by the geological conditions at the site of construction: parameters such as soil thickness, slope, bedrock quality and soil type. The geological parameters determine the amounts of earthworks (i.e. volumes of soil and rock that will be excavated and blasted), transportation need for excavated materials as well as the availability of building materials. The study presents a new geographic information system (GIS)-based approach for utilizing spatial geological data in three dimensions (i.e. length, width and depth) in order to improve estimates on earthworks during the early stages of road infrastructure planning. Three main methodological steps were undertaken: mass balance calculation, life cycle inventory analysis and spatial mapping of greenhouse gas (GHG) emissions and energy use. The proposed GIS-based approach was later evaluated by comparing with the actual values of extracted material of a real road construction project. The results showed that the estimate of filling material was the most accurate, while the estimate for excavated soil and blasted rock had a wide variation from

    Price is an inherent part of marketing mix. It is used for multiple reasons, from skimming consumer's surplus to antimarketing. In public transport, higher prices are often used in rush hours. The logic is to give an incentive to customers to travel outside rush hours, thus more evenly distribute...... the load. But it is possible to argue that prices should be lower in rush hours because means of public transportation tend to be full, i.e. there is a lower comfort of travelling, possibly even taking longer to travel the same distance. It is also possible to argue that the prices should be the same all...

    The European Union's Hydrocarbon energy supply depends heavily on imports. While the European Commission has recommended diversifying and increasing domestic resources, notably with renewable resources which should grow to 20 % by 2020, dependence on hydrocarbon imports will remain not only substantial, but will increase. Particular attention must thus be paid to the question of transportation, and also to the countries of origin, investments in infrastructures, their protection, relations with transit countries, 'competing consumers' (notably China and emerging countries, but also the United States), energy wastefulness in producing countries, and finally, price. Security of supply depends on adequate and reliable infrastructure, and must always be thought of in the long term. This entirely revised edition of the fourth study conducted by the European Governance and Geopolitics of Energy Program at Ifri includes discussions about pipeline routes and potential outputs, their current use and financial requirements for transportation, ongoing projects and those planned for the future, their cost, their financing and their probable operational start-up date. While all infrastructures are necessarily examined (including Norway, the United Kingdom, and North Africa), particular attention is paid to transportation infrastructure that connects Europe with Russia and the former Soviet Union (Central Asia, Caspian Sea). It will be immediately clear that the issue of gas is dominant in current discussions. Contents: 1. Setting up Gas and Oil Infrastructures in Europe. 2. EU Actions on Gas and Oil Infrastructure. 3.

    The article describes the method of analysis of the energy costs of transport infrastructure objects using BIM software. The paper consideres several options of orientation of a building using SketchUp and IES VE software programs. These options allow to choose the best direction of the building facades. Particular attention is given to a distribution of a temperature field in a cross-section of the wall according to the calculation made in the ELCUT software. The issues related to calculation of solar radiation penetration into a building and selection of translucent structures are considered in the paper. The article presents data on building codes relating to the transport sector, on the basis of which the calculations were made. The author emphasizes that BIM-programs should be implemented and used in order to optimize a thermal behavior of a building and increase its energy efficiency using climatic data.

    Quantification of emissions of greenhouse effect gases associated to transport infrastructures has been addressed in different ways. The first tools for this purpose appeared with the application of ISO 14040 standards (Life cycle analysis) that, applied to the particular case of energetic resources, led to a new concept known as carbon footprint. There is a specific standard for this quantification (ISO 14064) according to which, for the case of infrastructures, emissions and environmental effects linked to the whole life cycle are assessed taking into account all the stages: building, exploitation, maintenance and dismantling. the key point to perform this analysis is the accurate definition of a calculation methodology to be applied to the inventory of activities covered, in order to avoid information lacks, overlaps or redundancies. Quantification tools for emissions are effectively a reality, but social and political will, supported by strong economical reasons recognizing energy as a vital resource, is necessary for these tools to be developed, enhanced and used in a systematic way as a key decision element to choice among different transport alternatives.

    In the present study, we propose a novel game-theoretic pricing model describing the interaction between producers and retailers of goods in conditions of poor transport infrastructure and sparse geographical distribution of the points of sale. The proposed model generalizes the Stackelberg leadership model for an arbitrary number of leaders and followers. We show that the model always has a Nash and Stackelberg equilibria. We also provide formulas for the equilibrium prices and volume of sales. As an example we model diesel pricing in south Siberia. Our model found no signs of a cartel. The results of this paper can be used by policymakers to inform market regulations aimed at promoting free competition and avoiding monopolies in production and retail of goods.

    2015-11-01

    Full Text Available The main objective of the study was (1 to assess the level of negative impact of the road transport sector on the green infrastructure; (2 to compare the policy on green infrastructure with the actual direction of changes in transport systems; (3 to assess plans for transport development and some predictions on future impact. The research was carried out in the Poznan Metropolitan Area with the use of kernel density estimation (GIS. The analyses show that the key problem is the fragmentation of valuable natural areas and the routing of high traffic intensity roads through and nearby these areas which cause conflicts. The most negative transportation influence occurs in the agglomeration centre, where the quality of the environment is already low. At the same time existing land-use and transport strategies propose solutions neutralizing these negative impacts. Nevertheless current trends and especially new transport investment seem to negate official strategies and intensify the negative impacts on the green infrastructure.

    The developed societies have as challenge, among others, to achieve a mobility development based on economic models of low carbon and energy efficient, making it accessible to the entire population. In this context, the sustainable mobility seems to meet the economic, social and environmental needs, minimizing their negative impact. There are three factors that are relevant: (1) infrastructures; (2) modes of transport more ecological and safe, and (3) operations and services for passengers and freights.The objective of this research is to provide guidance to investment in sustainable transport infrastructures that are truly useful and effective. In particular we have studied the case of the railway, using the following information: details of the infrastructure; cost of construction (per kilometre); maintenance cost, and life cycle. This information may be relevant to consider their possible business models.The methodology of this research was focused in the detailed analysis of the infrastructure use and maintenance criteria, the market opportunities for freight development and the available data to validate the obtained results from the software tool reached in this work. Our research includes the different following aspects:• Evaluation of the supported traffic by the rail line.• Relevant items to be considered in the rail infrastructure. Defining the track, we can group items in two sets: civil and rail installations.• Rolling stock available. Locomotives and wagons are modelled to introduce the data as convenience for the user.Besides our research includes the development of software, Decision System Tool (DST), for studying the construction and maintenance cost of railway infrastructure.

    The National Aeronautics and Space Administration (NASA), U.S. Department of Transportation, Federal Aviation Administration, industry stakeholders, and academia, have joined forces to pursue the NASA National General Aviation Roadmap leading to a Small Aircraft Transportation System (SATS). This strategic undertaking has a 25-year goal to bring next-generation technologies and improve travel between remote communities and transportation centers in urban areas by utilizing the nation's 5,400 public-use general aviation airports. To facilitate this initiative, a comprehensive upgrade of public infrastructure must be planned, coordinated, and implemented within the framework of the national air transportation system. The Nebraska NASA EPSCoR Program has proposed to deliver research support in key public infrastructure areas in coordination with the General Aviation Program Office at the NASA Langley Research Center. Ultimately, SATS may permit tripling aviation system throughput capacity by tapping the underutilized general aviation facilities to achieve the national goal of doorstep-to-destination travel at four times the speed of highways for the nation's suburban, rural, and remote communities.

    The significant increase in passenger transport activity (cars) experienced by Spain and its associated increase in energy consumption have several associated negative aspects, including a greater dependence on foreign energy sources and higher GHG emissions. Therefore, reducing the level of transport activity would bring important socioeconomic and environmental benefits. The aim of this paper, which focuses on energy consumption in the passenger transport, is fourfold: (1) to provide a diagnostic of energy consumption in the Spanish passenger transport system and the related problems; (2) to develop a model to calculate price and income elasticities of demand for transport fuel; (3) to apply this model to the Spanish passenger transport sector; (4) to infer policy recommendations derived from the results of the diagnostic and the model. It is claimed that, in view of those low price elasticities and high income elasticities and if a reduction in the scale of transport activity is deemed socially desirable, a combination of instruments is necessary. Fuel taxes play an important role within this combination. Apart from their long-term effects, the low price elasticity of demand for transport fuel would allow the collection of a significant amount of revenues, which could eventually be earmarked to encourage reductions in private transport demand and modal shifts with other instruments.

    The petroleum-based transportation fuel system is complex and highly developed, in contrast to the nascent low-petroleum, low-carbon alternative fuel system. This report examines how expansion of the low-carbon transportation fuel infrastructure could contribute to deep reductions in petroleum use and greenhouse gas (GHG) emissions across the U.S. transportation sector. Three low-carbon scenarios, each using a different combination of low-carbon fuels, were developed to explore infrastructure expansion trends consistent with a study goal of reducing transportation sector GHG emissions to 80% less than 2005 levels by 2050.These scenarios were compared to a business-as-usual (BAU) scenario and were evaluated with respect to four criteria: fuel cost estimates, resource availability, fuel production capacity expansion, and retail infrastructure expansion.

    Walking and cycling bring health and environmental benefits, but there is little robust evidence that changing the built environment promotes these activities in populations. This study evaluated the effects of new transport infrastructure on active commuting and physical activity. Quasi-experimental analysis nested within a cohort study. Four hundred and sixty-nine adult commuters, recruited through a predominantly workplace-based strategy, who lived within 30 kilometers of Cambridge, United Kingdom and worked in areas of the city to be served by the new transport infrastructure. The Cambridgeshire Guided Busway opened in 2011 and comprised a new bus network and a traffic-free walking and cycling route. Exposure to the intervention was defined using the shortest distance from each participant's home to the busway. Change in weekly time spent in active commuting between 2009 and 2012, measured by validated 7-day recall instrument. Secondary outcomes were changes in total weekly time spent walking and cycling and in recreational and overall physical activity, measured using the validated Recent Physical Activity Questionnaire. Data were analyzed in 2014. In multivariable multinomial regression models--adjusted for potential sociodemographic, geographic, health, and workplace confounders; baseline active commuting; and home or work relocation-exposure to the busway was associated with a significantly greater likelihood of an increase in weekly cycle commuting time (relative risk ratio=1.34, 95% CI=1.03, 1.76) and with an increase in overall time spent in active commuting among the least active commuters at baseline (relative risk ratio=1.76, 95% CI=1.16, 2.67). The study found no evidence of changes in recreational or overall physical activity. Providing new sustainable transport infrastructure was effective in promoting an increase in active commuting. These findings provide new evidence to support reconfiguring transport systems as part of public health improvement

    Regional data of the Central German Uplands are extracted from the German landslide database in order to understand the complex interactions between landslide risks and public risk awareness considering transportation infrastructure. Most information within the database is gathered by means of archive studies from inventories of emergency agencies, state, press and web archives, company and department records as well as scientific and (geo)technical literature. The information includes land use practices, repair and mitigation measures with resultant costs of the German road network as well as railroad and waterway networks. It therefore contains valuable information of historical and current landslide impacts, elements at risk and provides an overview of spatiotemporal changes in social exposure and vulnerability to landslide hazards over the last 120 years. On a regional scale the recorded infrastructure damages, and consequential repair or mitigation measures were categorized and classified, according to relevant landslide types, processes and types of infrastructure. In a further step, the data of recent landslides are compared with historical and modern repair and mitigation measures and are correlated with socioeconomic concepts. As a result, it is possible to identify some complex interactions between landslide hazard, risk perception, and damage impact, including time lags and intensity thresholds. The data reveal distinct concepts of repairing respectively mitigating landslides on different types of transportation infrastructure, which are not exclusively linked to higher construction efforts (e.g. embankments on railroads and channels), but changing levels of economic losses and risk perception as well. In addition, a shift from low cost prevention measures such as the removal of loose rock and vegetation, rock blasting, and catch barriers towards expensive mitigation measures such as catch fences, soil anchoring and rock nailing over time can be noticed

    The European Union?s hydrocarbon energy supply depends heavily on imports. While the European Commission has recommended diversifying and increasing domestic resources, notably with renewable resources which should grow to 20% by 2020, dependence on hydrocarbon imports will remain not only substantial, but will increase. Particular attention must thus be paid to the question of transportation, and also to the countries of origin, investments in infrastructure, their protection, relations with transit countries, 'competing consumers? (notably China and emerging countries, but also the United States), energy wastefulness in producing countries, and, finally, price. Security of supply depends on adequate and reliable infrastructure, and must always be thought of in the long term. This entirely revised edition of the fourth study conducted by the European Governance and Geopolitics of Energy program at Ifri includes discussions about pipeline routes and potential outputs, their current use and financial requirements for transportation, ongoing projects and those planned for the future, their cost, their financing, and their probable operational start-up date. While all infrastructures are necessarily included (including Norway, the United Kingdom, and North Africa), particular attention is paid to transportation infrastructure that connects Europe with Russia and the former Soviet Union (Central Asia, Caspian Sea). It will be immediately clear that the issue of gas is dominant in current discussions. (author)

  20. Adaptation Becoming Business as Usual: A Framework for Climate-Change-Ready Transport Infrastructure

    Directory of Open Access Journals (Sweden)

    Andrew D. Quinn

    2018-04-01

    Full Text Available Extreme weather damages and disrupts transport infrastructure in a multitude of ways. Heavy rainfall and ensuing landslides or flooding may lead to road or rail closures; extreme heat can damage road surfaces, or cause tracks, signalling or electronic equipment to overheat, or thermal discomfort for passengers. As extreme weather is expected to occur more frequently in the future, transport infrastructure owners and operators must increase their preparedness in order to reduce weather-related service disruption and the associated financial costs. This article presents a two-sided framework for use by any organisation to develop climate-change-ready transport infrastructure, regardless of their current level of knowledge or preparedness for climate change. The framework is composed of an adaptation strategy and an implementation plan, and has the overarching ambition to embed climate change adaptation within organisational procedures so it becomes a normal function of business. It advocates adaptation pathways, i.e., sequential adaptive actions that do not compromise future actions. The circular, iterative structure ensures new knowledge, or socio-economic changes may be incorporated, and that previous adaptations are evaluated. Moreover, the framework aligns with existing asset management procedures (e.g., ISO standards or governmental or organisational approaches to climate change adaptation. By adopting this framework, organisations can self-identify their own level of adaptation readiness and seek to enhance it.

    Improving energy efficiency is the primary method adopted by the Chinese government in an effort to achieve energy conservation target in the transport sector. However, the offsetting effect of energy rebound would greatly reduce its real energy-saving potentials. We set up a Linear Approximation of the Almost Ideal Demand System Model (LA-AIDS model) to estimate the rebound effect for passenger transportation in China. Real energy conservation effect of improving energy efficiency can also be obtained in the process. The result shows that the rebound effect is approximately 107.2%. This figure signifies the existence of ‘backfire effect’, indicating that efficiency improvement in practice does not always lead to energy-saving. We conclude that one important factor leading to the rebound effect, is the refined oil pricing mechanism. China's refined oil pricing mechanism has been subjected to criticism in recent years. The results of simulation analysis show that the rebound could be reduced to approximately 90.7% if the refined oil pricing mechanism is reformed. In this regard, we suggest further reforms in the current refined oil pricing mechanism. - Highlights: ► We set up the LA-AIDS model to estimate traffic service demand for urban residents. ► The size of the rebound effect for passenger transportation in China is evaluated. ► The rebound effect for passenger transportation in China is 107.2%. ► Reform of oil pricing could reduced the rebound to 90.7%. ► Reform of oil pricing might be an effective method for mitigating rebound effect

    The three business units that Enbridge operates are crude oil pipelines; natural gas liquids (NGL) transportation; and gas transmission and distribution. The need for more infrastructure will increase as the demand for natural gas increases. This presentation outlined the issues that surround and sometimes impede infrastructure development. It also emphasized the need for northern gas supply at a time when conventional natural gas supplies are decreasing and demand is growing. Additional LNG supply is required along with new supply from Alaska, Mackenzie Delta and the east coast. The issue of a secure source of supply was discussed along with northern gas expectations. It is expected that Mackenzie Delta gas (1.2 bcf/day) will be available by 2008 to 2010 and Alaska North Slope gas (4 bcf/day) will be available from 2012 to 2014. Gas demand by industrial, residential, commercial and power generation sectors across North America was illustrated. The challenge lies in creating infrastructure to move the supply to where it is most in demand. General infrastructure issues were reviewed, such as prices, regulatory streamlining, lead times, stakeholder issues and supporting infrastructure. 19 figs

  3. COMPETITION AND PRICING OF ESSENTIAL INPUTS: THE CASE OF ACCESS CHARGES FOR THE USE OF THE ITALIAN RAIL INFRASTRUCTURE

    2013-12-01

    Full Text Available This paper explores the access charge for the use of the Italian rail infrastructure. Access problems arise when the provision of a complete service to end users requires the combination of two or more inputs, one of which is non-competitive (OECD, 2004. It is a well-known fact that excessive access charges mean higher prices for rail passengers and rail freight companies when using the infrastructure. We conclude that the structure of the access charge has changed significantly with the recent introduction of the HS/HC (high-speed and high-capacity network; specifically, the fixed component has lost importance, whilst the variable component reaches 94%. The results of this paper provide evidence of the access charge for HS/HC being above 13 €/km.

    With the latest results on expected future increase in air temperature and precipitation changes reported by the Intergovernmental Panel on Climate Change (IPCC), the climate robustness of important infrastructure is of raising concern in Norway, as well as in the rest of Europe. Economic consequences of natural disasters have increased considerably since 1950. In addition to the effect of demographic changes such as population growth, urbanization and more and more concentration of valuable assets, this increase is also related to an augmenting frequency of extreme events, such as storms, flooding, drought, and landslides. This change is also observable in Norway, where the increased frequency of strong precipitation has led to frequent flooding and landslide events during the last 20 years. A number of studies show that climate change causes an increase in both frequency and intensity of several types of extreme weather, especially when it comes to precipitation. Such extreme weather events greatly affect the transport infrastructure, with numerous and long closures of roads and railroads, in addition to damage and repair costs. Frequent closures of railroad and roads lead to delay or failure in delivery of goods, which again may lead to a loss of customers and/or - eventually - markets. Much of the Norwegian transport infrastructure is more than 50 years old and therefore not adequately dimensioned, even for present climatic conditions. In order to assess these problems and challenges posed to the Norwegian transport infrastructure from present-day and future extreme weather events, the project "Impacts of extreme weather events on infrastructure in Norway (InfraRisk)" was performed under the research Council of Norway program 'NORKLIMA', between 2009 and 2013. The main results of the project are: - Moderate to strong precipitation events have become more frequent and more intense in Norway over the last 50 years, and this trend continues throughout the 21st

  13. Managing uncertainty: Lessons from volcanic lava disruption of transportation infrastructure in Puna, Hawaii.

    Science.gov (United States)

    Kim, Karl; Pant, Pradip; Yamashita, Eric

    A recent lava flow in Puna, Hawaii, threatened to close one of the major highways serving the region. This article provides background information on the volcanic hazards and describes events, responses, and challenges associated with managing a complex, long-duration disaster. In addition to the need to better understand geologic hazards and threats, there is a need for timely information and effective response and recovery of transportation infrastructure. This requires coordination and sharing of information between scientists, emergency managers, transportation planners, government agencies, and community organizations. Transportation assets play a critical role in terms of problem definition, response, and recovery. The challenges with managing a long-duration event include: (1) determining when a sufficient threat level exists to close roads; (2) identifying transportation alternatives; (3) assessing impacts on communities including the direct threats to homes, businesses, structures, and infrastructure; (4) engaging communities in planning and deliberation of choices and alternatives; and (5) managing uncertainties and different reactions to hazards, threats, and risks. The transportation planning process provides a pathway for addressing initial community concerns. Focusing not just on roadways but also on travel behavior before, during, and after disasters is a vital aspect of building resilience. The experience in Puna with the volcano crisis is relevant to other communities seeking to adapt and manage long-term threats such as climate change, sea level risk, and other long-duration events.

  14. Mathematical programming (MP) model to determine optimal transportation infrastructure for geologic CO2 storage in the Illinois basin

    Science.gov (United States)

    Rehmer, Donald E.

    Analysis of results from a mathematical programming model were examined to 1) determine the least cost options for infrastructure development of geologic storage of CO2 in the Illinois Basin, and 2) perform an analysis of a number of CO2 emission tax and oil price scenarios in order to implement development of the least-cost pipeline networks for distribution of CO2. The model, using mixed integer programming, tested the hypothesis of whether viable EOR sequestration sites can serve as nodal points or hubs to expand the CO2 delivery infrastructure to more distal locations from the emissions sources. This is in contrast to previous model results based on a point-to- point model having direct pipeline segments from each CO2 capture site to each storage sink. There is literature on the spoke and hub problem that relates to airline scheduling as well as maritime shipping. A large-scale ship assignment problem that utilized integer linear programming was run on Excel Solver and described by Mourao et al., (2001). Other literature indicates that aircraft assignment in spoke and hub routes can also be achieved using integer linear programming (Daskin and Panayotopoulos, 1989; Hane et al., 1995). The distribution concept is basically the reverse of the "tree and branch" type (Rothfarb et al., 1970) gathering systems for oil and natural gas that industry has been developing for decades. Model results indicate that the inclusion of hubs as variables in the model yields lower transportation costs for geologic carbon dioxide storage over previous models of point-to-point infrastructure geometries. Tabular results and GIS maps of the selected scenarios illustrate that EOR sites can serve as nodal points or hubs for distribution of CO2 to distal oil field locations as well as deeper saline reservoirs. Revenue amounts and capture percentages both show an improvement over solutions when the hubs are not allowed to come into the solution. Other results indicate that geologic

    2014-05-01

    Reducing greenhouse gas emissions to avert potentially disastrous global climate change requires substantial redevelopment of infrastructure systems. Cities are recognized as key actors for leading such climate change mitigation efforts. We have studied the greenhouse gas inventories and underlying characteristics of 22 global cities. These cities differ in terms of their climates, income, levels of industrial activity, urban form and existing carbon intensity of electricity supply. Here we show how these differences in city characteristics lead to wide variations in the type of strategies that can be used for reducing emissions. Cities experiencing greater than ~1,500 heating degree days (below an 18 °C base), for example, will review building construction and retrofitting for cold climates. Electrification of infrastructure technologies is effective for cities where the carbon intensity of the grid is lower than ~600 tCO2e GWh-1 whereas transportation strategies will differ between low urban density (~6,000 persons km-2) cities. As nation states negotiate targets and develop policies for reducing greenhouse gas emissions, attention to the specific characteristics of their cities will broaden and improve their suite of options. Beyond carbon pricing, markets and taxation, governments may develop policies and target spending towards low-carbon urban infrastructure.

    Full Text Available Modeling of long-term forecasts of prices and demand on regional energy markets requires accounting for the future changes in the interactions between the greater economy and its energy sector, along with the possible emergence of new factors and specific regional features determining those interactions. The proposed approach allows the study of a correlation between demand and prices for motor fuel, taking into account the competition of energy carriers, the dynamics of energy prices, resource constraints, the use of new technologies and the uncertainty of input data. The main feature of the proposed approach is the combined estimation of the price elasticity of demand for motor fuel with optimization of fuel supply in the region. Thus the author determined elasticity of demand based on the comparison of economic efficiency of the use of different fuels. The study includes results of experimental calculations and forecasted price according to demand for motor fuel in freight transportation for the expected development conditions of the Far Eastern federal district

    During times of crisis, communities and regions rely heavily on critical infrastructure systems to support their emergency management response and recovery activities. Therefore, the resilience of critical infrastructure systems to crises is a pivotal factor to a community’s overall resilience. Critical infrastructure resilience can be influenced by many factors, including State policies – which are not always uniform in their structure or application across the United States – were identified by the U.S. Department of Homeland Security as an area of particular interest with respect to their the influence on the resilience of critical infrastructure systems. This study focuses on developing an analytical methodology to assess links between policy and resilience, and applies that methodology to critical infrastructure in the Transportation Systems Sector. Specifically, this study seeks to identify potentially influential linkages between State transportation capital funding policies and the resilience of bridges located on roadways that are under the management of public agencies. This study yielded notable methodological outcomes, including the general capability of the analytical methodology to yield – in the case of some States – significant results connecting State policies with critical infrastructure resilience, with the suggestion that further refinement of the methodology may be beneficial.

    The objective of this chapter is to create a methodology to model the emergent behavior during a disruption in the transportation system and that calculates economic losses due to such a disruption, and to understand how an extreme event affects the road transportation network. The chapter discusses a system dynamics approach which is used to model the transportation road infrastructure system to evaluate the different factors that render road segments inoperable and calculate economic consequences of such inoperability. System dynamics models have been integrated with business process simulation model to evaluate, design, and optimize the business process. The chapter also explains how different factors affect the road capacity. After identifying the various factors affecting the available road capacity, a causal loop diagram (CLD) is created to visually represent the causes leading to a change in the available road capacity and the effects on travel costs when the available road capacity changes.

    After having outlined how oil price collapse changes the economic deal, the authors analyse the determining factors of this collapse: slowing demand, exceeding supply, financialization of oil markets, no decision of reduction of production by the OPEC, decision by major companies to postpone investments rather than to re-balance short-term supply, production adjustment related to shale oil production. The second part analyses and discusses the economic consequences of oil price collapse: immediate impact on the French economy (reduction of the energy bill, different effects on the different economic actors, main related risks), economic scenarios on a medium term (contribution of models of macro-economic balance, possible economic growth of 0.4 due to oil price reduction, uncertain behaviour of economic actors, risk of deflation). In the third part, the authors make some proposals aimed at adapting the economy in order to take advantage of oil price reduction: to support energy transition with a required reform of energy taxing (for example for automotive fuels), to invest associated savings in energy transition and in transport infrastructure, to help households and companies in their energy transition

    In addition to arranging for storage and disposal of radioactive waste, the US Department of Energy (DOE) must develop a safe and efficient transportation system in order to deliver the material that has accumulated at various sites throughout the country. The ability to transport radioactive waste safely has been demonstrated during the past 20 years: DOE has made over 2,000 shipments of spent fuel and other wastes without any fatalities or environmental damage related to the radioactive nature of the cargo. To guarantee the efficiency of the transportation system, DOE must determine the optimal combination of rail transport (which allows greater payloads but requires special facilities) and truck transport Utilizing trucks, in turn, calls for decisions as to when to use legal weight trucks or, if feasible, overweight trucks for fewer but larger shipments. As part of the transportation system, the Facility Interface Capability Assessment (FICA) study contributes to DOE`s development of transportation plans for specific facilities. This study evaluates the ability of different facilities to receive, load and ship the special casks in which radioactive materials will be housed during transport In addition, the DOE`s Near-Site Transportation Infrastructure (NSTI) study (forthcoming) will evaluate the rail, road and barge access to 76 reactor sites from which DOE is obligated to begin accepting spent fuel in 1998. The NSTI study will also assess the existing capabilities of each transportation mode and route, including the potential for upgrade.

    Achieving the Department of Energy target of an 80% reduction in greenhouse gas emissions by 2050 depends on transportation-related strategies combining technology innovation, market adoption, and changes in consumer behavior. This study examines expanding low-carbon transportation fuel infrastructure to achieve deep GHG emissions reductions, with an emphasis on fuel production facilities and retail components serving light-duty vehicles. Three distinct low-carbon fuel supply scenarios are examined: Portfolio: Successful deployment of a range of advanced vehicle and fuel technologies; Combustion: Market dominance by hybridized internal combustion engine vehicles fueled by advanced biofuels and natural gas; Electrification: Market dominance by electric drive vehicles in the LDV sector, including battery electric, plug-in hybrid, and fuel cell vehicles, that are fueled by low-carbon electricity and hydrogen. A range of possible low-carbon fuel demand outcomes are explored in terms of the scale and scope of infrastructure expansion requirements and evaluated based on fuel costs, energy resource utilization, fuel production infrastructure expansion, and retail infrastructure expansion for LDVs. This is one of a series of reports produced as a result of the Transportation Energy Futures (TEF) project, a Department of Energy-sponsored multi-agency project initiated to pinpoint underexplored transportation-related strategies for abating GHGs and reducing petroleum dependence.

    2001-01-01

    Reform strategies in the transportation market, such as the Win-Win Transportation Solutions, can provide several economic, social and environmental benefits. The strategies are cost effective, technically feasible reforms based on market principles which help create a more equitable and efficient transportation system that supports sustainable economic development. The benefits they provide include reduced traffic congestion, road and parking facility savings, consumer savings, equity, safety and environmental protection. They also increase economic productivity. If fully implemented, they could reduce motor vehicle impacts by 15 to 30 per cent and could help achieve the Kyoto emission reduction targets. Examples of Win-Win strategies at the federal level include: (1) removal of subsidies to oil production and internalized costs, and (2) tax exempt employer provided transfer benefits. Examples of Win-Win strategies at the state/provincial level include: (1) distance-based vehicle insurance and registration fees, (2) least-coast transportation planning and funding, (3) revenue-neutral tax shifting, (4) road pricing, (5) reform motor carrier regulations for competition and efficiency, (6) local and regional transportation demand management programs, (7) more efficient land use, (8) more flexible zoning requirements, (9) parking cash out, (10) transportation management associations, (11) location-efficient housing and mortgages, (12) school and campus trip management, (13) car sharing, (14) non-motorized transport improvements, and (15) traffic calming. It was noted that any market reform that leads to more efficient use of existing transportation systems can provide better economic development benefits. 9 refs., 1 tab., 1 fig

  17. Stormwater Design Return Period Standards for U.S. Transportation Infrastructure: How Are States Approaching Resilience?

    Science.gov (United States)

    Samaras, C.; Lopez, T.

    2016-12-01

    Climate change is projected to increase the frequency and intensity of precipitation in many regions, which is relevant for stormwater engineering designs and resilience in the transportation sector. Existing and future stormwater infrastructure is generally designed for historical and stationary hydrologic conditions. For example, the design return period is based on statistical analysis of past precipitation events, often over a 50-year historical timeline. The design return period translates into how much peak precipitation volume a system is designed for in a state, and provides information about the performance of a drainage structure. The higher the design period used by an engineer for a given stormwater system, the more peak stormwater volume the system can convey. Therefore, design return periods can be associated with a design's near-term and long-term resilience. However, there is a tradeoff between the choice of design return period, the total infrastructure capital cost, and the resilience of a system to heavy precipitation events. This study analyzes current stormwater infrastructure design guidelines for state departments of transportation in the contiguous United States, in order to understand how stormwater design return periods vary across states and provide insight into the resilience of current stormwater systems design. The study found that the design return period varies considerably across the United States by roadway functional class and drainage classification, as well as within climate regions. Understanding this variation will help states identify possible vulnerabilities, highlight deficiencies across states and infrastructure types, and help in updating design return periods to increase the climate resilience of stormwater infrastructure.

The main targeted objectives are Firstly, practical, in-depth discussion of the future shape of the major trans-European energy and transport networks by 2010-2020 and, secondly, dissemination of the results of European research and technological development (RTD) programmes. The conference also provided a platform to float ideas and present programmes, approaches and results obtained at European or national level in these sectors. (Author)

  3. Do Transport Infrastructures Promote the Foreign Direct Investments Attractiveness? Empirical Investigation from Four North African Countries

    Directory of Open Access Journals (Sweden)

    2018-03-01

    Full Text Available The relationship among foreign direct investments and economic growth is a very controversial issue that has given rise to an abundant literature. Numerous research studies examine the bidirectional causal relationship and investigate the major determinants of these investments. In the same order of ideas, this article gives an empirical study from four North African countries to evaluate the role of transport infrastructures to improve the territorial attractiveness for the foreign direct investment. The present paper starts by a theoretical study explaining the role of transport as a major determinant of FDI. In a second section, we represent the empirical study. By using an econometric model with panel data, we found that traditional determinants of FDI have the most significant influence on the international investors’ decision. However, the same findings verify a positive impact of transport and consider it as a new important factor with strategic issues that cannot be avoided. The empirical validation from the four countries leads to verify that it is necessary to adopt development strategies that take into account the transport infrastructures and logistics function

    Full Text Available Regional logistics development plans have become a key element for an effective – regional economy in Austria. Efforts to develop the region of Carinthia – which represents a substantial transport hub on the Baltic–Adriatic Axis – depend on targeted infrastructure investments combined with well-utilized and accessible modes of transport. As decisions on transport mode choice are made within companies, their involvement in planning processes is crucial. Therefore a more consistent approach to Carinthia’s logistics infrastructure developments is required. The view of regional businesses is considered a significant basis for further public and managerial decision making with regard to the importance of future logistics developments.

    2009-07-01

    In addition to regulating the construction and operation of 70,000 km of oil and natural gas pipelines in Canada, the National Energy Board (NEB) regulates the trade of natural gas, oil and natural gas liquids. This report provided an assessment of the Canadian hydrocarbon transportation system in relation to its ability to provide a robust energy infrastructure. Data was collected from NEB-regulated pipeline companies and a range of publicly available sources to determine if adequate pipeline capacity is in place to transport products to consumers. The NEB also used throughput and capacity information received from pipeline operators as well as members of the investment community. The study examined price differentials compared with firm service tolls for transportation paths, as well as capacity utilization on pipelines and the degree of apportionment on major oil pipelines. This review indicated that in general, the Canadian pipeline transportation system continues to work effectively, with adequate pipeline capacity in place to move products to consumers who need them. 9 tabs., 30 figs., 3 appendices.

    Full Text Available Policy management of modern China aims to achieve a high level of welfare state. One of the important components that contributes to the achievement of this goal is the expansion of China's cooperation with the Middle East countries in all fields. At present, China is interested in obtaining energy from the Middle East oil fields. Of great importance is the transport infrastructure expansion between the regions. Construction and operation of oil pipelines, gas pipelines and land transport routes will reduce the risks of transporting raw materials and other goods from one region to another. The paper discusses the features of the development of rail and sea links as part of the strategy of «economic belt of the Silk Road» and «Marine Silk Road of XXI century».

  8. The ISTIMES project: a new integrated system for monitoring critical transport infrastructures interested by natural hazards

    Proto, Monica; Massimo, Bavusi; Francesco, Soldovieri

    2010-05-01

    The research project "Integrated System for Transport Infrastructure surveillance and Monitoring by Electromagnetic Sensing" (ISTIMES), was approved in the 7th Framework Programme, in the Joint Call ICT and Security and started on 1st July 2009. The purpose of ISTIMES project is to design, assess and promote an ICT-based system, exploiting distributed and local sensors, for non-destructive electromagnetic monitoring in order to achieve the critical transport infrastructures more reliable and safe. The transportation sector's components are susceptible to the consequences of natural disasters and can also be attractive as terrorist targets. The sector's size, its physically dispersed and decentralized nature, the many public and private entities involved in its operations, the critical importance of cost considerations, and the inherent requirement of convenient accessibility to its services by all users - make the transportation particularly vulnerable to security and safety threats. As well known, the surface transportation system consists of interconnected infrastructures including highways, transit systems, railroads, airports, waterways, pipelines and ports, and the vehicles, aircraft, and vessels that operate along these networks. Thus, interdependencies exist between transportation and nearly every other sector of the economy and the effective operation of this system is essential to the European economic productivity; therefore, transportation sector protection is of paramount importance since threats to it may impact other industries that rely on it. The system exploits an open network architecture that can accommodate a wide range of sensors, static and mobile, and can be easily scaled up to allow the integration of additional sensors and interfacing with other networks. It relies on heterogeneous state-of-the-art electromagnetic sensors, enabling a self-organizing, self-healing, ad-hoc networking of terrestrial sensors, supported by specific satellite

    1992-01-01

    On a conference (Gas for Europe in the 1990's) during the Gasexpo '91 the author held a speech of which the Dutch text is presented here. Attention is paid to the current European pricing methods (prices based on the costs of buying, transporting and distributing the natural gas and prices based on the market value, which is deducted from the prices of alternative fuels), and the transparency of the prices (lack of information on the way the prices are determined). Also attention is paid to the market signal transparency and gas-gas competition, which means a more or less free market of gas distribution. The risks of gas-to-gas competition for a long term price stability, investment policies and security of supply are discussed. Opposition against the Third Party Access (TPA), which is the program to implement gas-to-gas competition, is caused by the fear of natural gas companies for lower gas prices and lower profits. Finally attention is paid to government regulation and the activities of the European Commission (EC) in this matter. 1 fig., 6 ills., 1 tab

  12. Health Impacts of Increased Physical Activity from Changes in Transportation Infrastructure: Quantitative Estimates for Three Communities

    Science.gov (United States)

    2015-01-01

    Recently, two quantitative tools have emerged for predicting the health impacts of projects that change population physical activity: the Health Economic Assessment Tool (HEAT) and Dynamic Modeling for Health Impact Assessment (DYNAMO-HIA). HEAT has been used to support health impact assessments of transportation infrastructure projects, but DYNAMO-HIA has not been previously employed for this purpose nor have the two tools been compared. To demonstrate the use of DYNAMO-HIA for supporting health impact assessments of transportation infrastructure projects, we employed the model in three communities (urban, suburban, and rural) in North Carolina. We also compared DYNAMO-HIA and HEAT predictions in the urban community. Using DYNAMO-HIA, we estimated benefit-cost ratios of 20.2 (95% C.I.: 8.7–30.6), 0.6 (0.3–0.9), and 4.7 (2.1–7.1) for the urban, suburban, and rural projects, respectively. For a 40-year time period, the HEAT predictions of deaths avoided by the urban infrastructure project were three times as high as DYNAMO-HIA's predictions due to HEAT's inability to account for changing population health characteristics over time. Quantitative health impact assessment coupled with economic valuation is a powerful tool for integrating health considerations into transportation decision-making. However, to avoid overestimating benefits, such quantitative HIAs should use dynamic, rather than static, approaches. PMID:26504832

    Organizational Strategies for Critical Transportation Infrastructure: Characteristics of Urban Resilience. The Case of Montreal. Stéphane Beauregard M.Sc. Candidate École nationale d'administration publique Julie-Maude Normandin Ph.D. Candidate École nationale d'administration publique Marie-Christine Therrien Professor École nationale d'administration publique The proposed paper presents preliminary results on the resilience of organizations managing critical infrastructure in the Metropolitan Montreal area (Canada). A resilient city is characterized by a network of infrastructures and individuals capable of maintaining their activities in spite of a disturbance (Godschalk, 2002). Critical infrastructures provide essential services for the functioning of society. In a crisis situation, the interruption or a decrease in performance of critical infrastructures could have important impacts on the population. They are also vulnerable to accidents and cascading effects because on their complexity and tight interdependence (Perrow, 1984). For these reasons, protection and security of the essential assets and networks are one of the objectives of organizations and governments. But prevention and recovery are two endpoints of a continuum which include also intermediate concerns: ensuring organizational robustness or failing with elegance rather than catastrophically. This continuum also includes organizational resilience (or system), or the ability to recover quickly after an interruption has occurred. Wildavsky (1988) proposes that anticipation strategies work better against known problems while resilience strategies focus on unknown problems. Anticipation policies can unnecessarily immobilize investments against risks, while resilience strategies include the potential for a certain sacrifice in the interests of a more long-term survival and adaptation to changing threats. In addition, a too large confidence in anticipation strategies can bring loss of capacity of an

    The infrastructure for transportation in the United States allows for a high level of mobility and freight activity for the current population of 300 million residents, and several million business establishments. According to a Department of Transportation study, more than 230 million motor vehicles, ships, airplanes, and railroads cars were used on 6.4 million kilometers (4 million miles) of highways, railroads, airports, and waterways in 1998. Pipelines and storage tanks were considered to be part of this deteriorating infrastructure. The annual direct cost of corrosion in the infrastructure category was estimated to be approximately $22.6 billion in 1998. There were 583,000 bridges in the United States in 1998. Of this total, 200,000 bridges were steel, 235,000 were conventional reinforced concrete, 108,000 bridges were constructed using pre-stressed concrete, and the balance was made using other materials of construction. Approximately 15 percent of the bridges accounted for at this point in time were structurally deficient, primarily due to corrosion of steel and steel reinforcement. Iron-based amorphous metals, including SAM2X5 (Fe{sub 49.7}Cr{sub 17.7}Mn{sub 1.9}Mo{sub 7.4}W{sub 1.6}B{sub 15.2}C{sub 3.8}Si{sub 2.4}) and SAM1651 (Fe{sub 48}Mo{sub 14}Cr{sub 15}Y{sub 2}C{sub 15}B{sub 6}) have been developed, and have very good corrosion resistance. These materials have been prepared as a melt-spun ribbons, as well as gas atomized powders and thermal-spray coatings. During electrochemical testing in several environments, including seawater at 90 C, the passive film stabilities of these materials were found to be comparable to that of more expensive high-performance alloys, based on electrochemical measurements of the passive film breakdown potential and general corrosion rates. These materials also performed very well in standard salt fog tests. Chromium (Cr), molybdenum (Mo) and tungsten (W) provided corrosion resistance, and boron (B) enabled glass formation

    To appropriately mitigate environmental impacts from transportation, it is necessary for decision makers to consider the life-cycle energy use and emissions. Most current decision-making relies on analysis at the tailpipe, ignoring vehicle production, infrastructure provision, and fuel production required for support. We present results of a comprehensive life-cycle energy, greenhouse gas emissions, and selected criteria air pollutant emissions inventory for automobiles, buses, trains, and airplanes in the US, including vehicles, infrastructure, fuel production, and supply chains. We find that total life-cycle energy inputs and greenhouse gas emissions contribute an additional 63% for onroad, 155% for rail, and 31% for air systems over vehicle tailpipe operation. Inventorying criteria air pollutants shows that vehicle non-operational components often dominate total emissions. Life-cycle criteria air pollutant emissions are between 1.1 and 800 times larger than vehicle operation. Ranges in passenger occupancy can easily change the relative performance of modes.

    The planning of the expansion of transport of natural gas system; should keep in mind the changes that are happening in the structure of this industry in the country. In this respect, it is growing the number of actors private present in her, what determines a indicative type planning, whose main objective is to serve as information or guide in decisions of investment involved agents in the maintenance and the amplification of the net of transport for the national supply of natural gas. An indicative plan has objectives different to those of an operative plan of short term. While this last search to establish a program of adjustments to manage commitments of transport and to maintain, this way, the validity of the gas pipeline, The indicative plan of transport is guided to quantify the intensity of the financial effort that is required so that the capacity of the gas pipeline net, responds to the prospective growth of the gas industry. In other words, the indicative plan should contribute to identify the type of works and the one mounts of the investments that the transport of gas system needs in the long term. In this sense, it is important to specify the function objective that will optimize, this precision it should take into account, in our case, the foreseen expansion of the electric sector, because this it depends in good measure of the costs and of the geographical readiness of fuels as the natural gas and the coal. Said otherwise, the function objective that should be optimized involves the expansion of the net of transport of natural gas and the expansion of the generation capacity simultaneously and of the infrastructure of electricity transmission

    Full Text Available The globalization process involves the liberalization of the services and the air transportation industry is responsive to this reality. There is a developing tendency for global alliances and strategies in major airline companies. The globalization implies extending service networks in the whole world. Currently we are witnessing lower prices for domestic and foreign airline flights with benefits for the tourists’ business and leisure activities. The last minute offers and early booking prices provide a win-win situation, for the airline companies on one side and for the customers on the other side. The positive online reviews influence people buying decision because customers are more sensitive than ever to the services prices. Under this condition it is very interesting to see the evolution of pricing in the air transportation industry and the implication for the Romanian tourism sector.

    In Australia, residential electricity peak demand has risen steeply in recent decades, leading to higher prices as new infrastructure was needed to satisfy demand. One way of limiting further infrastructure-induced retail price rises is via ‘cost-reflective’ electricity network pricing that incentivises users to shift their demand to non-peak periods. Empowering consumers with knowledge of their energy usage is critical to maximise the potential benefits of cost-reflective pricing. This research consulted residential electricity consumers in three Australian states on their perceptions and acceptance of two cost-reflective pricing scenarios (Time-of-Use and Peak Capacity pricing) and associated technologies to support such pricing (smart meters, in-home displays and direct load control devices). An energy economist presented information to focus groups on the merits and limitations of each scenario, and participants’ views were captured. Almost half of the 53 participants were agreeable to Time-of-Use pricing, but did not have a clear preference for Peak Capacity pricing, where the price was based on the daily maximum demand. Participants recommended further information to both understand and justify the potential benefits, and for technologies to be introduced to enhance the pricing options. The results have implications for utilities and providers who seek to reduce peak demand. - Highlights: •Electricity price rises can be limited by ‘cost-reflective’ pricing. •We consulted residential electricity consumers on Time-of-Use and Peak Capacity pricing. •Understanding of peak electricity demand must increase to enable demand shift. •Interactive website could enable consumers to evaluate pricing options. •Smart meter adoption may increase if voluntary and includes an in-home display.

    Due to the shifting of city urban development causing the shift of city services center, so there is a change in space pattern and space structure in Banda Aceh, then resulting urban sprawl which can lead to congestion problem occurs on the arterial road in Banda Aceh, it can be seen from the increasing number of vehicles per year by 6%. Another issue occurs by urban sprawl is not well organized of settlement due to the uncontrolled use of space so that caused grouping or the differences in socioeconomic strata that can impact to the complexity of population mobility problem. From this background problem considered to be solved by a concept that is Transit Oriented Development (TOD), that is a concept of transportation development in co-operation with spatial. This research will get the model of transportation infrastructure development with TOD concept that can handle transportation problem in Banda Aceh, due to change of spatial structure, and to find whether TOD concept can use for the area that has a population in medium density range. The result that is obtained equation so the space structure is: Space Structure = 0.520 + 0.206X3 + 0.264X6 + 0.100X7 and Transportation Infrastructure Development = -1.457 + 0.652X1 + 0.388X5 + 0.235X6 + 0.222X7 + 0.327X8, So results obtained with path analysis method obtained variable influences, node ratio, network connectivity, travel frequency, travel destination, travel cost, and travel time, it has a lower value when direct effect with transportation infrastructure development, but if the indirect effect through the structure of space has a greater influence, can be seen from spatial structure path scheme - transportation infrastructure development.

    The choice of investment strategy has a great impact on the performance of transport infrastructure. Positive projects such as the "Subway plus Property" model in Hong Kong have created sustainable financial profits for the public transport projects. Owing to a series of public debt and other constraints, public-private partnership (PPP) was introduced as an innovative investment model to address this issue and help develop transport infrastructure. Yet, few studies provide a deeper understanding of relationships between PPP strategy and the performance of such transport projects (particularly the whole transport system). This paper defines the research scope as a regional network of freeway. With a popular PPP model, travel demand prediction method, and relevant parameters as input, agents in a simulation framework can simulate the choice of PPP freeway over time. The simulation framework can be used to analyze the relationship between the PPP strategy and performance of the regional freeway network. This study uses the Freeway Network of Yangtze River Delta (FN-YRD) in China as the context. The results demonstrate the value of using simulation models of complex transportation systems to help decision makers choose the right PPP projects. Such a tool is viewed as particularly important given the ongoing transformation of functions of the Chinese transportation sector, including franchise rights of transport projects, and freeway charging mechanism.

    Documenting existing state of practice is an initial step in developing future control infrastructure to be co-deployed for heterogeneous mix of connected and automated vehicles with human drivers while leveraging benefits to safety, congestion, and energy. With advances in information technology and extensive deployment of connected and automated vehicle technology anticipated over the coming decades, cities globally are making efforts to plan and prepare for these transitions. CAVs not only offer opportunities to improve transportation systems through enhanced safety and efficient operations of vehicles. There are also significant needs in terms of exploring how best to leverage vehicle-to-vehicle (V2V) technology, vehicle-to-infrastructure (V2I) technology and vehicle-to-everything (V2X) technology. Both Connected Vehicle (CV) and Connected and Automated Vehicle (CAV) paradigms feature bi-directional connectivity and share similar applications in terms of signal control algorithm and infrastructure implementation. The discussion in our synthesis study assumes the CAV/CV context where connectivity exists with or without automated vehicles. Our synthesis study explores the current state of signal control algorithms and infrastructure, reports the completed and newly proposed CV/CAV deployment studies regarding signal control schemes, reviews the deployment costs for CAV/AV signal infrastructure, and concludes with a discussion on the opportunities such as detector free signal control schemes and dynamic performance management for intersections, and challenges such as dependency on market adaptation and the need to build a fault-tolerant signal system deployment in a CAV/CV environment. The study will serve as an initial critical assessment of existing signal control infrastructure (devices, control instruments, and firmware) and control schemes (actuated, adaptive, and coordinated-green wave). Also, the report will help to identify the future needs for the signal

  10. Study on Comparison of Bidding and Pricing Behavior Distinction between Estimate Methods

    Morimoto, Emi; Namerikawa, Susumu

    The most characteristic trend on bidding and pricing behavior distinction in recent years is the increasing number of bidders just above the criteria for low-price bidding investigations. The contractor's markup is the difference between the bidding price and the execution price. Therefore, the contractor's markup is the difference between criteria for low-price bidding investigations price and the execution price in the public works bid in Japan. Virtually, bidder's strategies and behavior have been controlled by public engineer's budgets. Estimation and bid are inseparably linked in the Japanese public works procurement system. The trial of the unit price-type estimation method begins in 2004. On another front, accumulated estimation method is one of the general methods in public works. So, there are two types of standard estimation methods in Japan. In this study, we did a statistical analysis on the bid information of civil engineering works for the Ministry of Land, Infrastructure, and Transportation in 2008. It presents several issues that bidding and pricing behavior is related to an estimation method (several estimation methods) for public works bid in Japan. The two types of standard estimation methods produce different results that number of bidders (decide on bid-no bid strategy) and distribution of bid price (decide on mark-up strategy).The comparison on the distribution of bid prices showed that the percentage of the bid concentrated on the criteria for low-price bidding investigations have had a tendency to get higher in the large-sized public works by the unit price-type estimation method, comparing with the accumulated estimation method. On one hand, the number of bidders who bids for public works estimated unit-price tends to increase significantly Public works estimated unit-price is likely to have been one of the factors for the construction companies to decide if they participate in the biddings.

    New transport infrastructure may promote a shift towards active travel, thereby improving population health. The purpose of this study was to determine the effect of a major transport infrastructure project on commuters' mode of travel, trip frequency and distance travelled to work. Quasi-experimental analysis nested within a cohort study of 470 adults working in Cambridge, UK. The intervention consisted of the opening of a guided busway with a path for walking and cycling in 2011. Exposure to the intervention was defined as the negative of the square root of the shortest distance from home to busway. The outcome measures were changes in commute mode share and number of commute trips - both based on a seven-day travel-to-work record collected before (2009) and after (2012) the intervention - and change in objective commute distance. The mode share outcomes were changes in the proportions of trips (i) involving any active travel, (ii) involving any public transport, and (iii) made entirely by car. Separate multinomial regression models were estimated adjusting for commute and sociodemographic characteristics, residential settlement size and life events. Proximity to the busway predicted an increased likelihood of a large (>30 %) increase in the share of commute trips involving any active travel (relative risk ratio [RRR] 1.80, 95 % CI 1.27, 2.55) and a large decrease in the share of trips made entirely by car (RRR 2.09, 95 % CI 1.35, 3.21), as well as a lower likelihood of a small (travel (RRR 0.47, 95 % CI 0.28, 0.81). It was not associated with changes in the share of commute trips involving any public transport, the number of commute trips, or commute distance. The new infrastructure promoted an increase in the share of commuting trips involving active travel and a decrease in the share made entirely by car. Further analysis will show the extent to which the changes in commute mode share were translated into an increase in time spent in active commuting and

  12. Crude oil prices: Speculation versus fundamentals

    Kolodziej, Marek Krzysztof

    Beginning in 2004, the price of crude oil fluctuates rapidly over a wide range. Large and rapid price increases have recessionary consequences and dampen long-term infrastructural investment. I investigate whether price changes are driven by market fundamentals or speculation. With regard to market fundamentals, I revisit econometric evidence for the importance of demand shocks, as proxied by dry maritime cargo rates, on oil prices. When I eliminate transportation costs from both sides of the equation, disaggregate OPEC and non-OPEC production, and allow for more than one cointegrating relation, I find that previous specifications are inconsistent with arguments that demand shocks play an important role. Instead, results confirm the importance of OPEC supply shocks. I investigate two channels by which speculation may affect oil prices; the direct effect of trader behavior and changes in oil from a commodity to a financial asset. With regard to trader behavior, I find evidence that trader positions are required to explain the spread between spot and futures prices of crude oil on the New York Mercantile Exchange. The inclusion of trader positions clarifies the process of equilibrium error correction, such that there is bidirectional causality between prices and trader positions. This creates the possibility of speculative bubbles. With regard to oil as a commodity and/or financial asset, I use a Kalman Filter model to estimate the time-varying partial correlation between returns to investments in equity and oil markets. This correlation changes from negative to positive at the onset of the 2008 financial crisis. The low interest rates used to rescue the economy depress convenience yields, which reduces the benefits of holding oil as a commodity. Instead, oil becomes a financial asset (on net) as the oil market changed from contango to backwardation. Contradicting simple political narratives, my research suggests that both market fundamentals and speculation drive

  15. Motor fuel prices in Turkey

    Erdogdu, Erkan

    2014-01-01

    The world's most expensive motor fuel (gasoline, diesel and LPG) is sold most likely in the Republic of Turkey. This paper investigates the key issues related to the motor fuel prices in Turkey. First of all, the paper analyses the main reason behind high prices, namely motor fuel taxes in Turkey. Then, it estimates the elasticity of motor fuel demand in Turkey using an econometric analysis. The findings indicate that motor fuel demand in Turkey is quite inelastic and, therefore, not responsive to price increases caused by an increase in either pre-tax prices or taxes. Therefore, fuel market in Turkey is open to opportunistic behavior by firms (through excessive profits) and the government (through excessive taxes). Besides, the paper focuses on the impact of high motor fuel prices on road transport associated activities, including the pattern of passenger transportation, motorization rate, fuel use, total kilometers traveled and CO 2 emissions from road transportation. The impact of motor fuel prices on income distribution in Turkey and Turkish public opinion about high motor fuel prices are also among the subjects investigated in the course of the study. - Highlights: • The key issues (e.g. taxes) related to motor fuel prices in Turkey are explored. • Their impact on transport activities and income distribution is also investigated. • An econometric analysis is performed to estimate motor fuel demand in Turkey. • Motor fuel demand in Turkey is found to be quite inelastic. • Turkish fuel market is open to opportunistic behavior by firms and the government

    The aim of the present work is to design a model for evaluating the impact of planned infrastructures on species survival at the territorial scale by calculating a connectivity index. The method developed involves determining the effective distance of displacement between patches of the same habitat, simplifying earlier models so that there is no dependence on specific variables for each species. A case study is presented in which the model was used to assess the impact of the forthcoming roads and railways included in the Spanish Strategic Infrastructure and Transport Plan (PEIT, in its Spanish initials). This study took into account the habitats of peninsular Spain, which occupies an area of some 500,000 km(2). In this territory, the areas deemed to provide natural habitats are defined by Directive 92/43/EEC. The impact of new infrastructures on connectivity was assessed by comparing two scenarios, with and without the plan, for the major new road and railway networks. The calculation of the connectivity index (CI) requires the use of a raster methodology based on the Arc/Info geographical information system (GIS). The actual calculation was performed using a program written in Arc/Info Macro Language (AML); this program is available in FragtULs (Mancebo Quintana, 2007), a set of tools for calculating indicators of fragmentation caused by transport infrastructure (http://topografia.montes.upm.es/fragtuls.html). The indicator of connectivity proposed allows the estimation of the connectivity between all the patches of a territory, with no artificial (non-ecologically based) boundaries imposed. The model proposed appears to be a useful tool for the analysis of fragmentation caused by plans for large territories. Copyright 2009 Elsevier Ltd. All rights reserved.

    Full Text Available The provision of appropriate quality rail services has an important role in terms of railway infrastructure: quality of infrastructure maintenance, regulation of railway traffic, line capacity, speed, safety, train station organization, the allowable lines load and other infrastructure parameters.The analysis of experiences in transforming the railway systems points to the conclusion that there is no unique solution in terms of choice for institutional rail infrastructure management modes, although more than nineteen years have passed from the beginning of the implementation of the Directive 91/440/EEC. Depending on the approach to the process of restructuring the national railway company, adopted regulations and caution in its implementation, the existence or absence of a clearly defined transport strategy, the willingness to liberalize the transport market, there are several different ways for institutional management of railway infrastructure.A hybrid model for selection of modes of institutional rail infrastructure management was developed based on the theory of artificial intelligence, theory of fuzzy sets and theory of multicriteria optimization.KEY WORDSmanagement, railway infrastructure, organizational structure, hybrid model

  4. The Role of Distribution Infrastructure and Equipment in the Life-cycle Air Emissions of Liquid Transportation Fuels

    Science.gov (United States)

    Strogen, Bret Michael

    Production of fuel ethanol in the United States has increased ten-fold since 1993, largely as a result of government programs motivated by goals to improve domestic energy security, economic development, and environmental impacts. Over the next decade, the growth of and eventually the total production of second generation cellulosic biofuels is projected to exceed first generation (e.g., corn-based) biofuels, which will require continued expansion of infrastructure for producing and distributing ethanol and perhaps other biofuels. In addition to identifying potential differences in tailpipe emissions from vehicles operating with ethanol-blended or ethanol-free gasoline, environmental comparison of ethanol to petroleum fuels requires a comprehensive accounting of life-cycle environmental effects. Hundreds of published studies evaluate the life-cycle emissions from biofuels and petroleum, but the operation and maintenance of storage, handling, and distribution infrastructure and equipment for fuels and fuel feedstocks had not been adequately addressed. Little attention has been paid to estimating and minimizing emissions from these complex systems, presumably because they are believed to contribute a small fraction of total emissions for petroleum and first generation biofuels. This research aims to quantify the environmental impacts associated with the major components of fuel distribution infrastructure, and the impacts that will be introduced by expanding the parallel infrastructure needed to accommodate more biofuels in our existing systems. First, the components used in handling, storing, and transporting feedstocks and fuels are physically characterized by typical operating throughput, utilization, and lifespan. US-specific life-cycle GHG emission and water withdrawal factors are developed for each major distribution chain activity by applying a hybrid life-cycle assessment methodology to the manufacturing, construction, maintenance and operation of each

    The effect of transport infrastructure on walking is of interest to researchers because it provides an opportunity, from the public policy point of view, to increase physical activity (PA). We use an agent based model (ABM) to examine the effect of transport infrastructure on walking. Particular relevance is given to assess the effect of the growth of the Bus Rapid Transit (BRT) system in Bogotá on walking. In the ABM agents are assigned a home, work location, and socioeconomic status (SES) based on which they are assigned income for transportation. Individuals must decide between the available modes of transport (i.e., car, taxi, bus, BRT, and walking) as the means of reaching their destination, based on resources and needed travel time. We calibrated the model based on Bogota's 2011 mobility survey. The ABM results are consistent with previous empirical findings, increasing BRT access does indeed increase the number of minutes that individuals walk for transportation, although this effect also depends on the availability of other transport modes. The model indicates a saturation process: as more BRT lanes are added, the increment in minutes walking becomes smaller, and eventually the walking time decreases. Our findings on the potential contribution of the expansion of the BRT system to walking for transportation suggest that ABMs may prove helpful in designing policies to continue promoting walking.

    Climate change can affect coastal areas in a variety of ways. Coasts are sensitive to sea level rise, changes in the frequency/intensity of storms, increase in precipitation and storm surges. The resilience of transportation infrastructure located in Louisiana's coastal zone, against storm surges and climatic sea-level rise is critical. The net change in sea-level is affected by the increase in global sea level as well as land movement up or down. There are many places in coastal Louisiana that have a high subsidence rate. The subsidence could be related to excess extraction activities of oil and water, natural and/or human induced compaction, and tectonic movement. Where the land is sinking, the rate of relative sea level rise is larger than the global rate. Some of the fastest rates of relative sea level rise in the United States are occurring in areas where the land is sinking, including parts of the Gulf Coast. For example, coastal Louisiana has seen its relative sea level rise by eight inches or more in the last 50 years, which is about twice the global rate. Subsiding land in the Gulf area worsens the effects of relative sea level rise, increasing the risk of flooding in cities, inhabited islands, and tidal wetlands. The research team is investigating the trends for sea-level rise and land subsidence in coastal region of Louisiana. The variability in storm surges and its potential implication on the transportation infrastructure in the region is the focus of the study. The spatial maps will be created for spatial trends. This is extremely useful in being prepared for long-term natural hazards. The results of this study will be helpful to LADOTD and infrastructure managers and officials who are tasked with resiliency planning and management. Research results will also directly benefit university researchers in the state, Coastal Protection and Restoration Authority and LADOTD/LTRC through collaborative activity which will educate both professionals and the

  10. Impact of transportation and distribution factors on LPG supplies and prices

    Energy Technology Data Exchange (ETDEWEB)

    1980-01-01

    A predicted world LPG surplus of 14-20 million tons/y in the 1980's will not be absorbed even by the US and Japan, which are now the largest LPG consumers, unless market prices and return on investments are favorable enough to justify the investments required for the associated transportation and distribution facilities for new uses for LPG, e.g., as petrochemical feedstock, heating fuel, automotive fuel, or feedstock for the manufacture of high-octane additives. For the petrochemical industry, this implies new technologies and investments to optimize the equilibrium of the plants in connection with the market demand for ethylene, propylene, butadiene, and aromatic feedstocks. World LPG trade should rise from 13 million tons in 1979 to 40 million tons by 1985, of which 17 million tons will be moved on the Japanese captive market, up from about 10 million tons in 1979. The increased use of LPG in 1979 already boosted freight rates, which made shipowners consider new tonnage investment. The need for long-term supplier-user agreements as to LPG supplies and prices is discussed.

    The air transportation system is a significant driver of the U.S. economy, providing safe, affordable, and rapid transportation. During the past three decades airspace and airport capacity has not grown in step with demand for air transportation (+4% annual growth), resulting in unreliable service and systemic delays. Estimates of the impact of delays and unreliable air transportation service on the economy range from $32B to $41B per year. This report describes the results of an analysis of airline strategic decision-making with regards to: (1) geographic access, (2) economic access, and (3) airline finances. This analysis evaluated markets-served, scheduled flights, aircraft size, airfares, and profit from 2005-2009. During this period, airlines experienced changes in costs of operation (due to fluctuations in hedged fuel prices), changes in travel demand (due to changes in the economy), and changes in infrastructure capacity (due to the capacity limits at EWR, JFK, and LGA). This analysis captures the impact of the implementation of capacity limits at airports, as well as the effect of increased costs of operation (i.e. hedged fuel prices). The increases in costs of operation serve as a proxy for increased costs per flight that might occur if auctions or congestion pricing are imposed.

    Recent structural failures such as the I-35W Mississippi River Bridge in Minnesota have underscored the urgent need for improved methods and procedures for evaluating our aging transportation infrastructure. This research seeks to develop a basis for a Structural Health Monitoring (SHM) system to provide quantitative information related to the structural integrity of metallic structures to make appropriate management decisions and ensuring public safety. This research employs advanced structural analysis and nondestructive testing (NDT) methods for an accurate fatigue analysis. Metal railroad bridges in New Mexico will be the focus since many of these structures are over 100 years old and classified as fracture-critical. The term fracture-critical indicates that failure of a single component may result in complete collapse of the structure such as the one experienced by the I-35W Bridge. Failure may originate from sources such as loss of section due to corrosion or cracking caused by fatigue loading. Because standard inspection practice is primarily visual, these types of defects can go undetected due to oversight, lack of access to critical areas, or, in riveted members, hidden defects that are beneath fasteners or connection angles. Another issue is that it is difficult to determine the fatigue damage that a structure has experienced and the rate at which damage is accumulating due to uncertain history and load distribution in supporting members. A SHM system has several advantages that can overcome these limitations. SHM allows critical areas of the structure to be monitored more quantitatively under actual loading. The research needed to apply SHM to metallic structures was performed and a case study was carried out to show the potential of SHM-driven fatigue evaluation to assess the condition of critical transportation infrastructure and to guide inspectors to potential problem areas. This project combines the expertise in transportation infrastructure at New

  15. LNG development across Europe: Infrastructural and regulatory analysis

    International Nuclear Information System (INIS)

    Dorigoni, Susanna; Portatadino, Sergio

    2008-01-01

    In this paper, a cross-section infrastructural and regulatory analysis of the European LNG sector is presented. The LNG chain is maintained as being a good tool to enlarge the number of natural gas exporters to Europe, adding in this way to competition and to the achievement of the targets of the liberalisation process, which is a decrease in price for final customers and security of supply. The main reason for this is to be identified in the minor specificity of the regasification-plant-related investment compared with pipeline transportation. As a matter of fact, as the infrastructural analysis will show, the construction of new LNG receiving terminals is likely to bring about an increase in the number of importers fostering competition among them and shrinking their margins among the value chain. In this context, regulation is meant to play a key role in promoting investments without hindering competition. Nevertheless it is questionable whether LNG will be able to introduce competition beyond the European border (that is among producers) according to the forecasted supply and demand balance that is leading to a seller's market in the upstream sector. In this case, a huger part of the rent would go to the exporters leaving minor scope for competition down the European border. (author)

  16. Increase of transport-logistic servicing efficiency of Sverdlovsk region’s agroindustrial complex (on the example of grain cargoes transportation

    Directory of Open Access Journals (Sweden)

    Mikhail Borisovich Petrov

    2011-12-01

    Full Text Available In this paper, the features of Sverdlovsk region to ensure grain products are reviewed. The dependence of the agricultural sector and the conditions of its transport and logistics are substantiated. It is proven that transport and logistics services have the greatest impact not on harvest and on its processing and storage. The choice of transport and logistics service strategy for enterprises of agriculture depends on productivity, prices for grain and its products and the financial condition of the producer. From the calculations made in the paper it is visible that rail transport has a significant — more than double — advantage over the automobile transport on unit costs for carriage in bulk grain cargo, but, for some reason, road transport is beginning to occupy an increasing share in the carriage of grain cargoes. Based on comparative analysis of costs to import grain cargo using various transport modes, recommendations for improvement of transport and logistics infrastructure are made, as well as measures for improving the payments system between producers, processors and transporters are suggested.

  17. Petroleum products price regulation in Nov Scotia : a six-month review

    International Nuclear Information System (INIS)

    2007-03-01

    Gasoline pricing regulation was introduced in July 2006 in order to achieve the following 3 main objectives: (1) stabilize prices by reducing the frequency of price changes and creating more uniform pricing across the province, (2) maintain industry infrastructure by slowing or halting the decline in the dealer network, particularly in rural areas, by improving viability through regulated margins, and (3) minimize the cost to consumers since higher prices are expected to result from the actions needed to maintain price stability and the higher margins needed to maintain industry infrastructure. This report examined the extent to which these objectives were achieved and contained the findings and recommendations of a review of the first six months of gasoline price regulation in Nova Scotia. The report discussed the rationale for regulation, study objectives, approach, and warning signs. It also discussed gasoline regulation in Nova Scotia including how regulation works and implementing regulation. The Nova Scotia gasoline market was presented with reference to industry structure; pre-regulation competition and pricing; and how regulation may affect structure and competition. Last, the report discussed whether regulation was meeting the objectives and perspectives on regulation. Several recommendations were presented, such as reducing the benchmark price adjustment period from two weeks to one week; removing the price cap on full-serve gasoline; adopting a fixed and transparent formula for forward averaging and applying it at each adjustment; and considering a framework for regulatory review. 12 refs., 15 figs

  18. Spatial politics and infrastructure development: Analysis of historical transportation data in Gauteng - South Africa (1975–2003

    Directory of Open Access Journals (Sweden)

    McKay Tracey

    2017-03-01

    Full Text Available If South Africa’s Gauteng Province is to become a more ‘sustainable’, urbanised region, attention needs to be paid to building a transportation network that aligns with sustainable development principles. Currently, public transport passenger levels are low, whilst the geographical area it serves is large and becoming larger. This study analysed the long term, historical transportation trends of Gauteng by comparing four transport studies undertaken between 1975 and 2003. It reveals that an adherence to the ‘predict and provide’ transportation planning model has systematically enhanced road infrastructure over rail, and private over public transport. Effective, efficient and low cost public transport has been systematically under-provisioned; while a reliance on private vehicles is now entrenched and systemic. Racial segregation, spatial apartheid and weak urban land use planning, has resulted in an entrenched, low-density urban sprawl. Lastly, there is the need to collect comparable, longitudinal transportation data, if the successes and failures of policies are to be monitored.

    Two state companies are in charge of natural gas supply in Kazakhstan. They buy, transport and sell natural gas and have monopolized the industry and provoked increase of gas prices. Ministry of Oil and gas Industry proposed demonopolization. The restructuring that took place caused new distribution of tasks in the gas industry. A more competitive environment was created leading to normalization of the natural gas prices. All economic subjects were granted the right to acquire gas regardless the type of ownership. Measures implemented for reorganization of gas companies contributed to the reduction of gas transport costs and prices by 50% and to decrease of gas prices in the southern regions by 50%. Despite these measures gas prices for household sector are still unchanged and are below the import prices, the main reason being the low average household income

  2. Importance of Electricity Transport Pricing in Liberalised Energy Markets

    International Nuclear Information System (INIS)

    Wohlgemuth, N.

    2001-01-01

    Electricity has traditionally been supplied by vertically integrated companies providing generation, transmission and distribution services. Consumers have purchased a bundled commodity - delivered electricity - and there has been no need to price the components individually. This is no longer the case in competitive and unbundled electricity markets. One of the outstanding issues in the restructuring of the electricity markets is the way in which transmission costs are translated into tariffs. The efforts to create a single European electricity market are difficult to reconcile due to different national network pricing approaches. The European Commission's draft regulation on conditions for access to the network for cross-border exchanges of electricity sets general principles for the pricing of international electricity exchanges. Nodal pricing provides incentives for an efficient use of generation and transmission assets. Experience shows that nodal pricing is workable, and its use may be expected to increase progressively. Postage stamp pricing does not generally provide adequate incentives for efficiency. However, inefficiencies may be small under certain conditions, and postage stamp pricing has the advantage of being relatively transparent and easy to implement. This paper presents an overview of objectives related to an effective design of transmission pricing approaches, of transmission pricing models and presents recent developments in Europe in this respect. Due to the great number of institutional designs of electricity market organisations, it will be difficult to design and implement a model of cross-border transmission pricing that results in a high degree of non-discriminatory international competition in electricity markets, a key objective of the Electricity Directive.(author)

    In the last 15 years, worldwide air transportation has grown at an average yearly rate of 4.5%. Forecasts confirm that this could be the average increase rate for the next 20 years, although recent oscillation of oil price translated into a slowing down of such a trend, with several air companies forced out of business. Within this framework, low cost airlines keep increasing their market share, in so making airplane to compete with terrestrial transport modalities, not only for medium and long distance, but also for short trips. This is because air transport is obviously faster than transport by trains and cars, and most often it also is a cheaper option in money terms. In spite of its apparent success, air transportation is a source of concern for many analysts, because it is considered as the more energy intensive and polluting transport modality. In order to explore the correctness of such an issue, we compared air transportation to high speed trains and other modern terrestrial modalities, by using a 'whole-system' approach. The present study applies an LCA-like approach, by taking into account all the energy and materials directly and indirectly required to make and operate infrastructures (i.e. tunnels, railways, highways) and vehicles. Efficiency and environmental loading are assessed by means of Material Flow Accounting, Embodied Energy Analysis and Emergy Synthesis methods. Results point out that the gap among the environmental performances of air, road and railway modalities is significantly narrower than expected. The thermodynamic and environmental costs of road and railway infrastructure cannot be disregarded as negligible. In a selected number of cases these transport modalities perform even worse than the air transportation mode, where infrastructures play a much smaller role.

    As raw materials prices are rising, ore and coal mines in remote parts of the world have become profitable. Local infrastructures in these regions are not comparable with Europe. There are no rods or railways, and pipelines must be constructed parallel to rivers through deserts, mountains and rainforests. As a rule, pipelines do not follow favourable geological conditions but are constructed along the shortest possible rout to the nearest port or the nearest processing plant. Slurries are transported by pumping. (orig.)

    Transport policy and practice impacts health. Environmental Impact Assessments (EIAs) are regulated public policy mechanisms that can be used to consider the health impacts of major transport projects before they are approved. The way health is considered in these environmental assessments (EAs) is not well known. This research asked: How and to what extent was human health considered in EAs of four major transport projects in Australia. We developed a comprehensive coding framework to analyse the Environmental Impact Statements (EISs) of four transport infrastructure projects: three road and one light rail. The coding framework was designed to capture how health was directly and indirectly included. We found that health was partially considered in all four EISs. In the three New South Wales (NSW) projects, but not the one South Australian project, this was influenced by the requirements issued to proponents by the government which directed the content of the EIS. Health was assessed using human health risk assessment (HHRA). We found this to be narrow in focus and revealed a need for a broader social determinants of health approach, using multiple methods. The road assessments emphasised air quality and noise risks, concluding these were minimal or predicted to improve. The South Australian project was the only road project not to include health data explicitly. The light rail EIS considered the health benefits of the project whereas the others focused on risk. Only one project considered mental health, although in less detail than air quality or noise. Our findings suggest EIAs lag behind the known evidence linking transport infrastructure to health. If health is to be comprehensively included, a more complete model of health is required, as well as a shift away from health risk assessment as the main method used. This needs to be mandatory for all significant developments. We also found that considering health only at the EIA stage may be a significant

    Full Text Available Innovative solutions have been implemented to promote sustainable mobility in urban areas. In the Nantes area (northwestern part of France, alternatives to single-occupant car use have increased in the past few years. In the urban area, there is an efficient public transport supply, including tramways and a “busway” (Bus Rapid Transit, as well as bike-sharing services. In periurban and rural areas, there are carpool areas, regional buses and the new “tram-train” lines. In this article, we focus on the impact on house prices of these “sustainable” transportation infrastructures and policies, in order to evaluate their values. The implicit price of these sustainable transport offers was estimated through hedonic price functions describing the Nantes urban and periurban/rural housing markets. Spatial regression models (SAR, SEM, SDM and GWR were carried out to capture the effect of both spatial autocorrelation and spatial heterogeneity. The results show patterns of spatial heterogeneity of transportation offer implicit prices at two scales: (i between urban and periurban/rural areas, as well as (ii within each territory. In the urban area, the distance to such offers was significantly associated with house prices. These associations varied by type of transportation system (positive for tramway and railway stations and negative for bike-sharing stations. In periurban and rural areas, having a carpool area in a 1500-m buffer around the home was negatively associated with house prices, while having a regional bus station in a 500-m buffer was non-significant. Distance to the nearest railway station was negatively associated with house prices. These findings provide research avenues to help public policy-makers promote sustainable mobility and pave the way for more locally targeted interventions.

  15. A new methodology for modeling of direct landslide costs for transportation infrastructures

    Science.gov (United States)

    Klose, Martin; Terhorst, Birgit

    2014-05-01

    The world's transportation infrastructure is at risk of landslides in many areas across the globe. A safe and affordable operation of traffic routes are the two main criteria for transportation planning in landslide-prone areas. The right balancing of these often conflicting priorities requires, amongst others, profound knowledge of the direct costs of landslide damage. These costs include capital investments for landslide repair and mitigation as well as operational expenditures for first response and maintenance works. This contribution presents a new methodology for ex post assessment of direct landslide costs for transportation infrastructures. The methodology includes tools to compile, model, and extrapolate landslide losses on different spatial scales over time. A landslide susceptibility model enables regional cost extrapolation by means of a cost figure obtained from local cost compilation for representative case study areas. On local level, cost survey is closely linked with cost modeling, a toolset for cost estimation based on landslide databases. Cost modeling uses Landslide Disaster Management Process Models (LDMMs) and cost modules to simulate and monetize cost factors for certain types of landslide damage. The landslide susceptibility model provides a regional exposure index and updates the cost figure to a cost index which describes the costs per km of traffic route at risk of landslides. Both indexes enable the regionalization of local landslide losses. The methodology is applied and tested in a cost assessment for highways in the Lower Saxon Uplands, NW Germany, in the period 1980 to 2010. The basis of this research is a regional subset of a landslide database for the Federal Republic of Germany. In the 7,000 km² large Lower Saxon Uplands, 77 km of highway are located in potential landslide hazard area. Annual average costs of 52k per km of highway at risk of landslides are identified as cost index for a local case study area in this region. The

    Adequate infrastructure is essential to a country's growth. It provides a foundation which enables the economy to function. Until recently, most governments provided the physical infrastructure of industry: transport, communications, and power systems. Today, the trend is for governments to regulate monopolies while taking maximum advantage of private sector investment, decision-making and management. The private sector is increasingly being recognized as having the capacity to operate infrastructure projects more efficiently. (author)

    2010-01-01

    A wide range of fuels will be used in future transportation technologies. This presentation discussed refuelling infrastructure solutions for alternative fuels. A well-placed demonstration infrastructure will help to accelerate market development. Stakeholder collaboration is needed to create high value business paradigms and identify stakeholder benefits. Infrastructure paradigms include the home; businesses; retail public refuelling forecourts; and multi-fuel waste heat recovery sites. Commercial nodes can be developed along major transportation routes. Stakeholder groups include technology providers, supply chain and service providers, commercial end-users, and government. A successful alternative fuel infrastructure model will consider market development priorities, time frames and seed investment opportunities. Applications must be market-driven in order to expand. A case study of the natural gas vehicle (NGV) program in Ontario was also discussed, as well as various hydrogen projects. tabs., figs.

  18. STATE OF WATER SUPPLY INFRASTRUCTURE IN THE SUBCARPATHIAN CITIES

    Directory of Open Access Journals (Sweden)

    Katarzyna PIETRUCHA-URBANIK

    Full Text Available The characteristics of equipping the Subcarpathian province cities with water supply infrastructure was made on the basis of data collected from the Provincial Office, Statistical Office, reports submitted by water companies regarding the functioning of water supply infrastructure and literature data. The indicators characterizing water supply infrastructure were determined for the years 1995-2014. In the paper the indicators of equipping cities with water supply systems were presented. Also water consumption and changes in the length of the water supply network in the cities of the Subcarpathian Province were examined. The analysis shows that the water consumption for the years 1995-2014 decreased by almost 6 m3∙year-1 per capita. The reason for such situation was the increasing price of water and the ecological awareness of the inhabitants of the Subcarpathian region. In the last year of the analysis the water supply system in urban areas of the Subcarpathian province was used by 95% of the population and, for comparison, in rural areas by 77% of the population. In the paper also changes in prices for water in the Subcarpathian region were shown, on the basis of data from the water tariffs in individual water companies. The important element of urban development is the technical infrastructure which reduces the investment costs. The determined indicators of equipping cities with water supply systems show an upward trend in the development of technical infrastructure. Based on the operational data from the water companies the failure rates in selected water supply networks were determined.

    1995-12-01

    Unbundling and restructuring of local distribution services is the focus of the natural gas industry. As a result of regulatory reforms, a competitive local distribution market has emerged, and the validity of traditional cost-based regulation is being questioned. One alternative is to completely unbundle local distribution services and transform the local distribution company into a common carrier for intrastate transportation services. Three kinds of alternative pricing mechanisms are examined. For firm intrastate transportation services, cost-based pricing is the preferred method unless it can be shown that a competitive secondary market can be established and maintained. Pricing interruptible transportation capacity is discussed

    Network Science, Nonlinear Science and Infrastructure Systems has been written by leading scholars in these areas. Its express purpose is to develop common theoretical underpinnings to better solve modern infrastructural problems. It is felt by many who work in these fields that many modern communication problems, ranging from transportation networks to telecommunications, Internet, supply chains, etc., are fundamentally infrastructure problems. Moreover, these infrastructure problems would benefit greatly from a confluence of theoretical and methodological work done with the areas of Network Science, Dynamical Systems and Nonlinear Science. This book is dedicated to the formulation of infrastructural tools that will better solve these types of infrastructural problems. .

    Full Text Available Background: There has been considerable decline in the investment on road transport infrastructure in recent times, as a result of the dwindling economic investment owing to lowering gross domestic product (GDP since 2009. Objective: The objective of this study was to examine the relationship between road transport investment (ROTI and economic development (ED in South Africa. This article adopts the Harrod–Domar (HD model of economic growth and development theory, endogenous growth theory and Solow–Swan neoclassical growth model. Method: Data were derived from the South African Reserve Bank, Quantec database and Statistics South Africa (StatsSA between 1990 and 2014. It used time series, econometric models cointegration and vector error correction model (VECM to analyse. Result: The results of the estimation demonstrate that the explanatory variables account for approximately 86.7% variation in ED in South Africa. Therefore, there exists a positive relationship between ROTI and ED. Conclusion: This study established a long-run relationship between phenomena and demonstrates the role of road transport investment on economic development in South Africa.

    2008-01-01

    Suborbital space flight and space tourism are new potential markets that could significantly impact the National Airspace System (NAS). Numerous private companies are developing space flight capabilities to capture a piece of an emerging commercial space transportation market. These entrepreneurs share a common vision that sees commercial space flight as a profitable venture. Additionally, U.S. space exploration policy and national defense will impose significant additional demands on the NAS. Air traffic service providers must allow all users fair access to limited airspace, while ensuring that the highest levels of safety, security, and efficiency are maintained. The FAA's Next Generation Air Transportation System (NextGen) will need to accommodate spacecraft transitioning to and from space through the NAS. To accomplish this, space and air traffic operations will need to be seamlessly integrated under some common communications, navigation and surveillance (CNS) infrastructure. As part of NextGen, the FAA has been developing the Automatic Dependent Surveillance Broadcast (ADS-B) which utilizes the Global Positioning System (GPS) to track and separate aircraft. Another key component of NextGen, System-Wide Information Management/ Network Enabled Operations (SWIM/NEO), is an open architecture network that will provide NAS data to various customers, system tools and applications. NASA and DoD are currently developing a space-based range (SBR) concept that also utilizes GPS, communications satellites and other CNS assets. The future SBR will have very similar utility for space operations as ADS-B and SWIM has for air traffic. Perhaps the FAA, NASA, and DoD should consider developing a common space-based CNS infrastructure to support both aviation and space transportation operations. This paper suggests specific areas of research for developing a CNS infrastructure that can accommodate spacecraft and other new types of vehicles as an integrated part of NextGen.

    Full Text Available Infrastructure investing makes up a significant part of the financial institutions portfolio, and contributes to creating long-term assets cash flows. In addition, infrastructure assets are relatively inelastic in demand and price, and as such the asset has a good performance during the economic downturn. Properly structured infrastructure investments contribute to the diversification of the portfolio, due to the lack of correlation with the yield on bonds, stocks and real estate, and offer good protection against inflation. Applying the concept of project financing involves the application of the most advanced financial techniques and products that are able to ensure only credible international financial institutions and companies. Paper attempts to indicate the presence of financial institutions in project financing of infrastructure, as well as the benefits of this concept in expected to finance infrastructure in Serbia.

  10. China on the move: Oil price explosion?

    International Nuclear Information System (INIS)

    Skeer, Jeffrey; Wang Yanjia

    2007-01-01

    Rapid expansion of highway and jet traffic in China has created a surge of demand for oil products, putting pressure on world energy markets and petroleum product prices. This paper examines trends in freight and passenger traffic to assess how growth in China's transport demand relates to growth in China's economy, as well as the energy intensity of transport. Based on assumptions about demand elasticity and energy intensity, a range of scenarios is developed for China's oil demand through 2020. Incremental oil demand from China's transport sector is then compared with world oil demand projections to assess the likely impact on world oil prices. The finding is that new demand from China's transport sector would likely raise world oil prices in 2020 by 1-3% in reference scenarios or by 3-10% if oil supply investment is constrained

    1997-12-31

    The Diesel Cycle engine has already established itself as the engine-of-choice for the heavy duty transport industry because of its fuel efficiency, durability, and reliability. In addition, it has also been shown to be capable of using alternative fuels, albeit at efficiencies lower than that achieved with petroleum-derived diesel fuel. Alternative fuel dedicated engines have not made significant penetration of the heavy duty truck market because truck fleet operators need a cost-competitive fuel and reliable supply and fueling infrastructure. In lieu of forcing diverse fuels from many diverse domestic feedstocks onto the end-users, the Office of Heavy Vehicle Technologies envisions that a future fuels strategy for the heavy duty transport sector is one where the diverse feedstocks are utilized to provide a single fuel specification (dispensed from the existing fueling infrastructure) that would run efficiently in a single high efficiency energy conversion device, the Diesel Cycle engine. In so doing, the US Commercial transport industry may gain a measure of security from the rapid fuel price increases by relying less on a single feedstock source to meet its increasing fuel requirements.

    Science.gov (United States)

    Richard, Tom L

    2010-08-13

    Rapid growth in demand for lignocellulosic bioenergy will require major changes in supply chain infrastructure. Even with densification and preprocessing, transport volumes by mid-century are likely to exceed the combined capacity of current agricultural and energy supply chains, including grain, petroleum, and coal. Efficient supply chains can be achieved through decentralized conversion processes that facilitate local sourcing, satellite preprocessing and densification for long-distance transport, and business models that reward biomass growers both nearby and afar. Integrated systems that are cost-effective and energy-efficient will require new ways of thinking about agriculture, energy infrastructure, and rural economic development. Implementing these integrated systems will require innovation and investment in novel technologies, efficient value chains, and socioeconomic and policy frameworks; all are needed to support an expanded biofuels infrastructure that can meet the challenges of scale.

    Railway infrastructure plays an important role in the transportation of freight and passengers across the European Union. According to Eurostat, more than four billion passenger-kilometres were travelled on national and international railway lines of the EU28 in 2014. To further strengthen transport infrastructure in Europe, the European Commission will invest another € 24.05 billion in the transnational transport network until 2020 as part of its new transport infrastructure policy (TEN-T), including railway infrastructure. Floods pose a significant risk to infrastructure elements. Damage data of recent flood events in Europe show that infrastructure losses can make up a considerable share of overall losses. For example, damage to state and municipal infrastructure in the federal state of Saxony (Germany) accounted for nearly 60% of overall losses during the large-scale event in June 2013. Especially in mountainous areas with little usable space available, roads and railway lines often follow floodplains or are located along steep and unsteady slopes. In Austria, for instance, the flood of 2013 caused € 75 million of direct damage to railway infrastructure. Despite the importance of railway infrastructure and its exposure to flooding, assessments of potential damage and risk (i.e. probability * damage) are still in its infancy compared with other sectors, such as the residential or industrial sector. Infrastructure-specific assessments at the regional scale are largely lacking. Regional assessment of potential damage to railway infrastructure has been hampered by a lack of infrastructure-specific damage models and data availability. The few available regional approaches have used damage models that assess damage to various infrastructure elements (e.g. roads, railway, airports and harbours) using one aggregated damage function and cost estimate. Moreover, infrastructure elements are often considerably underrepresented in regional land cover data, such as

    The objective of this paper is to evaluate the performance of natural gas transportation utilities, focusing on the three-key strategic performance measures of profit, productivity, and price differential. We propose a methodology that expresses the three performance measures in a unified single equation using the Edgeworth index. The proposed methodology is applied to an international comparison of the performance of 28 natural gas transportation utilities operating in eight countries in which the business environments differ greatly. The empirical results show the possible causes of performance differences and may shed some light on the direction of regulatory policy, especially for developing countries that have relatively short histories in the natural gas industry, such as Korea.

    This article deals with the trends of the main fuel prices development in the Western European markets. There are two possible price development scenarios presented in the article. Transportation costs of various internationally traded fuels from various sources (Russia, Western Europe) are estimated and their most feasible values are considered. Fuel prices for the final big consumers are calculated adding the domestic distribution costs. Trends of heat and electricity price development in Lithuania during the period of 1991-1995 are analyzed. Forecasts of the electricity generation and supply costs are calculated according to various scenarios. Electricity prices will be lowest in the case of the further operation of the Ignalina NPP and low fuel prices in international markets. (author). 8 refs., 14 figs., 4 tabs

  20. Misunderstood markets: The case of California gasoline

    Science.gov (United States)

    Thompson, Jennifer Ruth

    In 1996, the California Air Resources Board (CARB) implemented a new benchmark for cleaner burning gasoline that is unique to California. Since then, government officials have often expressed concern that the uniqueness of petroleum products in California segregates the industry, allowing for gasoline prices in the State that are too high and too volatile. The growing concern about the segmentation of the California markets lends itself to analysis of spatial pricing. Spatial price spreads of wholesale gasoline within the state exhibit some characteristics that seem, on the surface, inconsistent with spatial price theory. Particularly, some spatial price spreads of wholesale gasoline appear larger than accepted transportation rates and other spreads are negative, giving a price signal for transportation against the physical flow of product. Both characteristics suggest some limitation in the arbitrage process. Proprietary data, consisting of daily product prices for the years 2000 through 2002, disaggregated by company, product, grade, and location is used to examine more closely spatial price patterns. My discussion of institutional and physical infrastructure outlines two features of the industry that limit, but do not prohibit, arbitrage. First, a look into branding and wholesale contracting shows that contract terms, specifically branding agreements, reduces the price-responsiveness of would-be arbitrageurs. Second, review of maps and documents illustrating the layout of physical infrastructure, namely petroleum pipelines, confirms the existence of some connections among markets. My analysis of the day-of-the-week effects on wholesale prices demonstrates how the logistics of the use of transportation infrastructure affect market prices. Further examination of spatial price relationships shows that diesel prices follow closely the Augmented Law of One Price (ALOP), and that branding agreements cause gasoline prices to deviate substantially ALOP.

    There are currently 27 nuclear reactor sites located in the southern region. In many instances, the most practicable modes of transportation of spent nuclear fuel from these sites we through the use of highway and rail systems. These two transportation modes have important differences that affect their applicability; chief among these, perhaps, is the fact that while highway systems are publicly owned and maintained rail lines are owned by private entities. For this reason, track condition and maintenance, usage rates and other aspects of rail transport can vary widely. This report reviews southern state, department plans for infrastructure upgrades in the vicinity of nuclear reactor sites.

    2016-06-01

    Full Text Available The paper presents a concept of urban green infrastructure and analyzes the features of its implementation in the urban development programmes of German cities. We analyzed the most shared articles devoted to the urban green infrastructure to see different approaches to definition of this term. It is based on materials of field research in the cities of Berlin and Leipzig in 2014-2015, international and national scientific publications. During the process of preparing the paper, consultations have been held with experts from scientific institutions and Administrations of Berlin and Leipzig as well as local experts from environmental organizations of both cities. Using the German cities of Berlin and Leipzig as examples, this paper identifies how the concept can be implemented in the program of urban development. It presents the main elements of green city model, which include mitigation of negative anthropogenic impact on the environment under the framework of urban sustainable development. Essential part of it is a complex ecological policy as a major necessary tool for the implementation of the green urban infrastructure concept. This ecological policy should embody not only some ecological measurements, but also a greening of all urban infrastructure elements as well as implementation of sustainable living with a greater awareness of the resources, which are used in everyday life, and development of environmental thinking among urban citizens. Urban green infrastructure is a unity of four main components: green building, green transportation, eco-friendly waste management, green transport routes and ecological corridors. Experience in the development of urban green infrastructure in Germany can be useful to improve the environmental situation in Russian cities.

    2016-04-01

    Strategic infrastructure networks include the highly complex and interconnected systems that are so vital to a city or state that any sudden disruption can result in debilitating impacts on human life, the economy and the society as a whole. Recently, various studies have applied complex network-based models to study the performance and vulnerability of infrastructure systems under various types of attacks and hazards - a major part of them is, particularly after the 9/11 incident, related to terrorism attacks. Here, vulnerability is generally defined as the performance drop of an infrastructure system under a given disruptive event. The performance can be measured by different metrics, which correspond to various levels of resilience. In this paper, we will address vulnerability and exposure of critical infrastructure in the Eastern Alps. The Federal State Tyrol is an international transport route and an essential component of the north-south transport connectivity in Europe. Any interruption of the transport flow leads to incommensurable consequences in terms of indirect losses, since the system does not feature redundant elements at comparable economic efficiency. Natural hazard processes such as floods, debris flows, rock falls and avalanches, endanger this infrastructure line, such as large flood events in 2005 or 2012, rock falls 2014, which had strong impacts to the critical infrastructure, such as disruption of the railway lines (in 2005 and 2012), highways and motorways (in 2014). The aim of this paper is to present how critical infrastructures as well as communities and societies are vulnerable and can be resilient against natural hazard risks and the relative cascading effects to different compartments (industrial, infrastructural, societal, institutional, cultural, etc.), which is the dominant by the type of hazard (avalanches, torrential flooding, debris flow, rock falls). Specific themes will be addressed in various case studies to allow cross

    Directory of Open Access Journals (Sweden)

    Eugen Ferdinand Spangenberg

    2017-12-01

    Full Text Available The current situation is the exponential increase in greenhouse gases (GHG, which is mainly caused by industrial and transport activities. The recent Paris agreement in 2015 (Framework Convention on Climate Change COP21, UNFCCC made it clear to everyone that CO2 emissions are to be limited in all areas of life. Alternative fuels with a lower environmental impact than carbon (CO2 emissions are hard to find if the overall footprint is to be taken into account. Nevertheless, there are some fuels that have less impact on climate change. One the other hand, the production of biofuels is a controversial matter, although it is a viable alternative to emissions reduction. CNG or LNG-powered vehicles are also better in terms of environmental pollution, but are hardly better with regard to CO2 impact when a Life Cycle Assessment (LCA is carried out. LNG (liquid natural gas, for example, is the future fuel in the maritime sector because of the stricter environmental regulations (SOx,NOx in the shipping industry. The battery-powered vehicle is another example of an environmentally friendly solution. The afore-mentioned measures can be considered as “abatement“ necessary in order to limit CO2 impact. The study shows that there are significant differences in the environmental impact between transport systems and the corresponding drive-system or associated energy base. The polluter should pay, which is a common basic principle in economic research. The Emission Trading Scheme (ETS has been introduced in order to ensure a reduction in CO2 output – emissions come with a price tag. An overall view is necessary, both en-vironmental and economic impact must be reconciled (cf. Spangenberg - TQI. The future viability of the transport system as we know it may change significantly over time if new environmental requirements or e.g. CO2 taxes or ETS are introduced in the freight sector. The abatement of CO2 should be effected primarily through technological

  8. Impact of Infrastructure and Production Processes on Rioja Wine Supply Chain Performance

    Directory of Open Access Journals (Sweden)

    José Roberto Díaz-Reza

    2018-01-01

    Full Text Available This paper presents a structural equation model for analyzing the relationship between four latent variables: infrastructure, production processes, transport benefits, and economic benefits within the supply chain for wine from La Rioja, Spain, by incorporating 12 observed variables. The model proposes six hypothesis that were tested using information gathered from 64 surveys completed by managers of several wineries in the region. The WarpPLS v.5® software (Version 5.0, Script Warp Systems, Laredo, TX, USA was used to execute the model and analyze the direct, indirect, and total effects among latent variables. The results show that the control of production processes is a direct source of economic and transport benefits because of its higher explanatory power of those variables. Similarly, infrastructure is a direct source of transport and production benefits, and some of them are given indirectly. In addition, infrastructure does not have a direct effect on economic benefits; however, there were indirect effects given through production process and transport benefits. Infrastructure is a very important variable because of its influence in the final performance, but also because of its high environmental impact. Finally, economic benefits were explained in 43.8%, 19.1% belonging to production process, 21.1% coming from transport benefits, and 3.7% from infrastructure.

    The spatial price problem means that if the supply price plus the transportation cost is less than the demand price, there exists a trade. Thus, after an amount of exchange, the demand price will decrease. This process is continuous until an equilibrium state is obtained. However, how the trade network structure affects this process has received little attention. In this paper, we give a evolving model to describe the levels of spatial price on different complex network structures. The simulation results show that the network with shorter path length is sensitive to the variation of prices.

  11. Measuring global gasoline and diesel price and income elasticities

    International Nuclear Information System (INIS)

    Dahl, Carol A.

    2012-01-01

    Price and income elasticities of transport fuel demand have numerous applications. They help forecast increases in fuel consumption as countries get richer, they help develop appropriate tax policies to curtail consumption, help determine how the transport fuel mix might evolve, and show the price response to a fuel disruption. Given their usefulness, it is understandable why hundreds of studies have focused on measuring such elasticities for gasoline and diesel fuel consumption. In this paper, I focus my attention on price and income elasticities in the existing studies to see what can be learned from them. I summarize the elasticities from these historical studies. I use statistical analysis to investigate whether income and price elasticities seem to be constant across countries with different incomes and prices. Although income and price elasticities for gasoline and diesel fuel are not found to be the same at high and low incomes and at high and low prices, patterns emerge that allow me to develop suggested price and income elasticities for gasoline and diesel demand for over one hundred countries. I adjust these elasticities for recent fuel mix policies, and suggest an agenda of future research topics. - Research highlights: ► Surveyed econometric studies of transport fuel demand. ► Developed price elasticities of demand for gasoline and diesel fuel for 120 countries. ► Developed income elasticities of demand for gasoline and diesel fuel for 120 countries. ► Suggested a research agenda for future work.

    In a context of strong energy dependence, the safety of supplies and the reliability of infrastructures remain of prime importance. The Europe of 27 is looking for the proper balance between excessive dependence and beneficial interdependence. A real competitive bidding about the potential paths of the Russian and CIS gas towards western Europe is taking place. However, a given energy infrastructure can change the economic and cultural relations and the prices as well. Interpreting the energy diplomacy between political and economical stakes has become a hard task. The underlying logic of the impressive number of projects in progress is extremely complex as many projects are in competition and linked with each others (like the BTC - Bakou-Tbilissi-Ceyhan, the Transcaspian and the South Stream). This study aims at presenting a comprehensive overview of the existing and planned projects with the help of a table which includes the oil and gas pipelines and the methane gas terminals. This study includes the imports coming from the north (Norway, UK), from the south (Algeria) and above all from the east (Russia and CIS). It includes the layout and the potential flow rate of these infrastructures, their present day use and financial conditions of transport, the projects in progress or planned, their cost, financing and possible date of commissioning. Even if the study encompasses all infrastructures (including Norway, UK and North Africa), it stresses on those linking Europe to Russia and to the post-soviet area (Central Asia, Caspian Sea).

  14. Canadian hydrocarbon transportation system : transportation assessment

    International Nuclear Information System (INIS)

    2006-06-01

    This document provided an assessment of the Canadian hydrocarbon transportation system. In addition to regulating the construction and operation of Canada's 45,000 km of pipeline that cross international and provincial borders, Canada's National Energy Board (NEB) regulates the trade of natural gas, oil and natural gas liquids. The ability of pipelines to delivery this energy is critical to the country's economic prosperity. The pipeline system includes large-diameter, cross-country, high-pressure natural gas pipelines, low-pressure crude oil and oil products pipelines and small-diameter pipelines. In order to assess the hydrocarbon transportation system, staff at the NEB collected data from pipeline companies and a range of publicly available sources. The Board also held discussions with members of the investment community regarding capital markets and emerging issues. The assessment focused largely on evaluating whether Canadians benefit from an efficient energy infrastructure and markets. The safety and environmental integrity of the pipeline system was also evaluated. The current adequacy of pipeline capacity was assessed based on price differentials compared with firm service tolls for major transportation paths; capacity utilization on pipelines; and, the degree of apportionment on major oil pipelines. The NEB concluded that the Canadian hydrocarbon transportation system is working effectively, with an adequate capacity in place on existing natural gas pipelines, but with a tight capacity on oil pipelines. It was noted that shippers continue to indicate that they are reasonably satisfied with the services provided by pipeline companies and that the NEB-regulated pipeline companies are financially stable. 14 refs, 11 tabs., 28 figs., 4 appendices

    The question of pricing train paths for "open access" railway networks in North America is discussed. An auction process is suggested as necessary to maintain transparency in the contracting process. Multiple random samples of auction pricing for a single track railway line demonstrate...... that the infrastructure entity will receive approximately 15.6% less than the true value of the contracted train paths. This loss of revenue threatens the objective of reducing government subsidy for the railway network. (C) 2012 Elsevier Ltd. All rights reserved....

    Wang, Bin; Hu, Boyang; Qiu, Charlie; Chu, Peter; Gadh, Rajit

    2015-02-17

    in this paper, we propose and implement a smart Electric Vehicle (EV) charging algorithm to control the EV charging infrastructures according to users’ price preferences. EVSE (Electric Vehicle Supply Equipment), equipped with bidirectional communication devices and smart meters, can be remotely monitored by the proposed charging algorithm applied to EV control center and mobile app. On the server side, ARIMA model is utilized to fit historical charging load data and perform day-ahead prediction. A pricing strategy with energy bidding policy is proposed and implemented to generate a charging price list to be broadcasted to EV users through mobile app. On the user side, EV drivers can submit their price preferences and daily travel schedules to negotiate with Control Center to consume the expected energy and minimize charging cost simultaneously. The proposed algorithm is tested and validated through the experimental implementations in UCLA parking lots.

    The ability to charge battery electric vehicles (BEVs) on a time scale that is on par with the time to fuel an internal combustion engine vehicle (ICEV) would remove a significant barrier to the adoption of BEVs. However, for viability, fast charging at this time scale needs to also occur at a price that is acceptable to consumers. Therefore, the cost drivers for both BEV owners and charging station providers are analyzed. In addition, key infrastructure considerations are examined, including grid stability and delivery of power, the design of fast charging stations and the design and use of electric vehicle service equipment. Each of these aspects have technical barriers that need to be addressed, and are directly linked to economic impacts to use and implementation. This discussion focuses on both the economic and infrastructure issues which exist and need to be addressed for the effective implementation of fast charging at 400 kW and above. In so doing, it has been found that there is a distinct need to effectively manage the intermittent, high power demand of fast charging, strategically plan infrastructure corridors, and to further understand the cost of operation of charging infrastructure and BEVs.

  19. Energy Aware Pricing in a Three-Tiered Cloud Service Market

    2016-09-01

    Full Text Available We consider a three-tiered cloud service market and propose an energy efficient pricing strategy in this market. Here, the end customers are served by the Software-as-a-Service (SaaS providers, who implement customized services for their customers. To host these services, these SaaS providers, in turn, lease the infrastructure related resources from the Infrastructure-as-a-Service (IaaS or Platform-as-a-Service (PaaS providers. In this paper, we propose and evaluate a mechanism for pricing between SaaS providers and Iaas/PaaS providers and between SaaS providers and the end customers. The pricing scheme is designed in a way such that the integration of renewable energy is promoted, which is a very crucial aspect of energy efficiency. Thereafter, we propose a technique to strategically provide an improved Quality of Service (QoS by deploying more resources than what is computed by the optimization procedure. This technique is based on the square root staffing law in queueing theory. We carry out numerical evaluations with real data traces on electricity price, renewable energy generation, workload, etc., in order to emulate the real dynamics of the cloud service market. We demonstrate that, under practical assumptions, the proposed technique can generate more profit for the service providers operating in the cloud service market.

  2. Investing in Port Infrastructure to Lower Trade Costs in East Asia

    Directory of Open Access Journals (Sweden)

    Kazutomo Abe

    2011-06-01

    Full Text Available We examine how port infrastructure affects trade and role of transport costs in driving exports and imports for East Asia. Existing studies use survey indexes to explain transport costs. These do not link investment in port infrastructure to transport costs. We include in our estimates a variable to represent the congestion of the ports to explain the transport costs. We find that the port congestion has significantly increased the transport costs from East Asia to the United States. Our analysis suggests that increase in port capacity by 10 percent could cut transport cost in East Asia by up to three percent. This translates into a 0.3 to 0.5 percent across-the-board tariff cut.

    This report aims at identifying measures to be implemented during coming years in order energy consumption of the transport sector to become consistent with energy scenarios, and at studying how these measures could be funded. After a presentation of the situation of the transport sector in terms of energy consumption (energy consumption by the different sub-sectors, greenhouse effect, relationship with mobility, issue of infrastructures and related investments) and of its objectives, this study proposes an overview of the content of various scenarios (NegaWatt, Ademe, Ministry of Ecology, Greenpeace). It proposes a brief overview and discussion of energy saving potentials and sources, and presents issues related to energy efficiency in the transport sector. It develops an action plan aimed at exploiting energy efficiency sources in transports. This action plan notably comprises: a political signal for a more efficient mobility, a support to change in mobility, actions in town planning to ease energy efficiency in transports, a more efficient use of the rolling stock, infrastructures for a more efficient transport sector, a price signal in favour of a more efficient transport. The next parts of the study discuss expenses of the transport sector, incomes and funding tools for energy efficiency in transports, financial needs for efficiency improvement, financial resources, and propose a road map

    Habitat loss and deterioration represent the main threats to wildlife species, and are closely linked to the expansion of roads and human settlements. Unfortunately, large-scale effects of these structures remain generally overlooked. Here, we analyzed the European transportation infrastructure network and found that 50% of the continent is within 1.5 km of transportation infrastructure. We present a method for assessing the impacts from infrastructure on wildlife, based on functional response curves describing density reductions in birds and mammals (e.g., road-effect zones), and apply it to Spain as a case study. The imprint of infrastructure extends over most of the country (55.5% in the case of birds and 97.9% for mammals), with moderate declines predicted for birds (22.6% of individuals) and severe declines predicted for mammals (46.6%). Despite certain limitations, we suggest the approach proposed is widely applicable to the evaluation of effects of planned infrastructure developments under multiple scenarios, and propose an internationally coordinated strategy to update and improve it in the future.

    Life-cycle cost (LCC) analysis is an economic technique used to assess the total costs associated with the lifetime of a system in order to support decision making in long term strategic planning. For complex systems, such as railway and road infrastructures, the cost of maintenance plays an important role in the LCC analysis. Costs associated with maintenance interventions can be more reliably estimated by integrating the probabilistic nature of the failures associated to these interventions in the LCC models. Reliability, Maintainability, Availability and Safety (RAMS) parameters describe the maintenance needs of an asset in a quantitative way by using probabilistic information extracted from registered maintenance activities. Therefore, the integration of RAMS in the LCC analysis allows obtaining reliable predictions of system maintenance costs and the dependencies of these costs with specific cost drivers through sensitivity analyses. This paper presents an innovative approach for a combined RAMS & LCC methodology for railway and road transport infrastructures being developed under the on-going H2020 project INFRALERT. Such RAMS & LCC analysis provides relevant probabilistic information to be used for condition and risk-based planning of maintenance activities as well as for decision support in long term strategic investment planning.

  11. Integrated Intermodal Passenger Transportation System

    2012-01-01

    Modern transportation consists of many unique modes of travel. Each of these modes and their respective industries has evolved independently over time, forming a largely incoherent and inefficient overall transportation system. Travelers today are forced to spend unnecessary time and efforts planning a trip through varying modes of travel each with their own scheduling, pricing, and services; causing many travelers to simply rely on their relatively inefficient and expensive personal automobile. This paper presents a demonstration program system to not only collect and format many different sources of trip planning information, but also combine these independent modes of travel in order to form optimal routes and itineraries of travel. The results of this system show a mean decrease in inter-city travel time of 10 percent and a 25 percent reduction in carbon dioxide emissions over personal automobiles. Additionally, a 55 percent reduction in carbon dioxide emissions is observed for intra-city travel. A conclusion is that current resources are available, if somewhat hidden, to drastically improve point to point transportation in terms of time spent traveling, the cost of travel, and the ecological impact of a trip. Finally, future concepts are considered which could dramatically improve the interoperability and efficiency of the transportation infrastructure.

  12. Higher prices, higher quality? Evidence from German nursing homes.

    This study investigates the relationship between prices and quality of 7400 German nursing homes. We use a cross section of public quality reports for all German nursing homes, which had been evaluated between 2010 and 2013 by external institutions. Our analysis is based on multivariate regressions in a two stage least squares framework, where we instrument prices to explain their effect on quality controlling for income, nursing home density, demographics, labour market characteristics, and infrastructure at the regional level. Descriptive analysis shows that prices and quality do not only vary across nursing homes, but also across counties and federal states and that quality and prices correlate positively. Second, the econometric analysis, which accounts for the endogenous relation between negotiated price and reported quality, shows that quality indeed positively depends on prices. In addition, more places in nursing homes per people in need are correlated with both lower prices and higher quality. Finally, unobserved factors at the federal state level capture some of the variation of reported quality across nursing homes. Our results suggest that higher prices increase quality. Furthermore, since reported quality and prices vary substantially across federal states, we conclude that the quality and prices of long-term care facilities may well be compared within federal states but not across.

    Failure of critical national infrastructures can result in major disruptions to society and the economy. Understanding the criticality of individual assets and the geographic areas in which they are located is essential for targeting investments to reduce risks and enhance system resilience. Within this study we provide new insights into the criticality of real-life critical infrastructure networks by integrating high-resolution data on infrastructure location, connectivity, interdependence, and usage. We propose a metric of infrastructure criticality in terms of the number of users who may be directly or indirectly disrupted by the failure of physically interdependent infrastructures. Kernel density estimation is used to integrate spatially discrete criticality values associated with individual infrastructure assets, producing a continuous surface from which statistically significant infrastructure criticality hotspots are identified. We develop a comprehensive and unique national-scale demonstration for England and Wales that utilizes previously unavailable data from the energy, transport, water, waste, and digital communications sectors. The testing of 200,000 failure scenarios identifies that hotspots are typically located around the periphery of urban areas where there are large facilities upon which many users depend or where several critical infrastructures are concentrated in one location. © 2017 Society for Risk Analysis.

    2008-07-01

    Our study, focused on gas prices in importing economies, describes wholesale prices and retail prices, their evolution for the last one or two decades, the economic mechanisms of price formation. While an international market for oil has developed thanks to moderate storage and transportation charges, these costs are much higher in the case of natural gas, which involves that this energy is still traded inside continental markets. There are three regional gas markets around the world: North America (the United States, importing mainly from Canada and Mexico), Europe (importing mainly from Russia, Algeria and Norway) and Asia (Japan, Korea, Taiwan, China and India, importing mainly from Indonesia, Malaysia and Australia). A market for gas has also developed in South America, but it will not be covered by our paper. In Europe and the US, due to large domestic resources and strong grids, natural gas is purchased mostly through pipelines. In Northeast Asia, there is a lack of such infrastructures, so imported gas takes mainly the form of Liquefied Natural Gas (LNG), shipped on maritime tankers. Currently, the LNG market is divided into two zones: the Atlantic Basin (Europe and US) and the Pacific Basin (Asia and the Western Coast of America). For the past few years, the Middle East and Africa have tended to be crucial suppliers for both LNG zones. Gas price formation varies deeply between regional markets, depending on several structural factors (regulation, contracting practises, existence of a spot market, liquidity, share of imports). Empirically, the degree of market opening (which corresponds to the seniority in the liberalization process) seems to be the primary determinant of pricing patterns. North America has the most liberalized and well-performing natural gas industry in the world. Gas pricing is highly competitive and is based on supply/demand balances. Spot and futures markets are developed. The British gas sector is also deregulated and thus follows a

  19. The use of the natural-gas pipeline infrastructure for hydrogen transport in a changing market structure

    International Nuclear Information System (INIS)

    Haeseldonckx, Dries; D'haeseleer, William

    2007-01-01

    In this paper, the transport and distribution aspects of hydrogen during the transition period towards a possible full-blown hydrogen economy are carefully looked at. Firstly, the energetic and material aspects of hydrogen transport through the existing natural-gas (NG) pipeline infrastructure is discussed. Hereby, only the use of centrifugal compressors and the short-term security of supply seem to constitute a problem for the NG to hydrogen transition. Subsequently, the possibility of percentwise mixing of hydrogen into the NG bulk is dealt with. Mixtures containing up to 17 vol% of hydrogen should not cause difficulties. As soon as more hydrogen is injected, replacement of end-use applications and some pipelines will be necessary. Finally, the transition towards full-blown hydrogen transport in (previously carrying) NG pipelines is treated. Some policy guidelines are offered, both in a regulated and a liberalised energy (gas) market. As a conclusion, it can be stated that the use of hydrogen-natural gas mixtures seems well suited for the transition from natural gas to hydrogen on a distribution (low pressure) level. However, getting the hydrogen gas to the distribution grid, by means of the transport grid, remains a major issue. In the end, the structure of the market, regulated or liberalised, turns out not to be important. (author)

    Pluvial and flash floods, related to massive sediment transport become phenomenon nowadays, under conditions of climate changes. Storm events, related to material damages appear at unexpected places and their effective control is only possible in form of prevention. To apply preventive measures, there have to be defined localities with reasonable reliability, which are endangered by surface runoff and sediment transport produced in the subcatchments, often at agriculturally used landscape. Classification of such localities, concerning of potential damages and magnitude of sediment transport shall be also included within the analyses, to design control measures effectively. Large scale project for whole territory of the Czech Republic (ca 80.000 km2) has therefore been granted b the Ministry of Interior of the Czech Republic, with the aim to define critical points, where interaction between surface runoff connected to massive sediment transport and infrastructure or vulnerable water bodies can occur and to classify them according to potential risk. Advanced GIS routines, based on analyses of land use, soil conditions and morphology had been used to determine the critical points - points, where significant surface runoff occurs and interacts with infrastructure and vulnerable water bodies, based exclusively on the contributing area - flow accumulation. In total, ca 150.000 critical points were determined within the Czech Republic. For each of critical points, its subcatchment had then been analyzed in detail, concerning of soil loss and sediment transport, using simulation model WATEM/SEDEM. The results were used for classification of potential risk of individual critical points, based on mean soil loss within subcatchment, total sediment transport trough the outlet point and subcatchment area. The classification has been done into 5 classes. The boundaries were determined by calibration survey and statistical analysis, performed at three experimental catchments area

    Huang, Yongxi

    Infrastructure systems support human activities in transportation, communication, water use, and energy supply. The dissertation research focuses on critical transportation infrastructure and renewable energy infrastructure systems. The goal of the research efforts is to improve the sustainability of the infrastructure systems, with an emphasis on economic viability, system reliability and robustness, and environmental impacts. The research efforts in critical transportation infrastructure concern the development of strategic robust resource allocation strategies in an uncertain decision-making environment, considering both uncertain service availability and accessibility. The study explores the performances of different modeling approaches (i.e., deterministic, stochastic programming, and robust optimization) to reflect various risk preferences. The models are evaluated in a case study of Singapore and results demonstrate that stochastic modeling methods in general offers more robust allocation strategies compared to deterministic approaches in achieving high coverage to critical infrastructures under risks. This general modeling framework can be applied to other emergency service applications, such as, locating medical emergency services. The development of renewable energy infrastructure system development aims to answer the following key research questions: (1) is the renewable energy an economically viable solution? (2) what are the energy distribution and infrastructure system requirements to support such energy supply systems in hedging against potential risks? (3) how does the energy system adapt the dynamics from evolving technology and societal needs in the transition into a renewable energy based society? The study of Renewable Energy System Planning with Risk Management incorporates risk management into its strategic planning of the supply chains. The physical design and operational management are integrated as a whole in seeking mitigations against the

    The ability to charge battery electric vehicles (BEVs) on a time scale that is on par with the time to fuel an internal combustion engine vehicle (ICEV) would remove a significant barrier to the adoption of BEVs. However, for viability, fast charging at this time scale needs to also occur at a price that is acceptable to consumers. Therefore, the cost drivers for both BEV owners and charging station providers are analyzed. In addition, key infrastructure considerations are examined, including grid stability and delivery of power, the design of fast charging stations and the design and use of electric vehicle service equipment. Each of these aspects have technical barriers that need to be addressed, and are directly linked to economic impacts to use and implementation. Here, this discussion focuses on both the economic and infrastructure issues which exist and need to be addressed for the effective implementation of fast charging up to 350 kW. In doing so, it has been found that there is a distinct need to effectively manage the intermittent, high power demand of fast charging, strategically plan infrastructure corridors, and to further understand the cost of operation of charging infrastructure and BEVs.

    2015-05-01

    Full Text Available The management of research and development (R&D in the transport infrastructure field is complex due to the multidisciplinary nature of the work. The literature shows that linear R&D models that progress from idea through to consumer product are not suitable for the management of such multi-disciplinary projects. This study focuses on determining the key characteristics required for a systems-based approach to the management of R&D projects. The information and data was compiled from literature reviews, interviews, and an e-mail survey with responses from 42 significant international R&D programmes. The findings confirmed the need for a systems-based approach to R&D management. The study formulated twelve principles or tenets for a new, systems-based approach.

  7. Welfare distribution effect of a price reduction in the Dutch gas transport market: A scenario analysis of regulatory policy, market form and rent allocation

    International Nuclear Information System (INIS)

    Van Witteloostuijn, Arjen; Van Marrewijk, Charles

    2007-01-01

    As part of the larger energy market deregulation program, the Dutch energy authority - DTe - has developed the habit to force the Dutch gas transport enterprise - Gas Transport Services, or GTS - to lower its prices. DTe's key argument is that lower gas transport prices will benefit the end-user. Indeed, that might well be the case. This policy, in general, is in line with European legislation on the liberalization of the gas market. We model and simulate the (domestic) welfare effects of a 5 percent transport price reduction. From this, we conclude that at least three observations complicate matters substantially. First, GTS is government-owned, and the dominant shipper - Gasunie Trade and Supply (or GasTerra, as it was recoined recently) - is partly so (50%). Second, shippers enter into the competitive game to make profits. Third, not only is the majority of gas transported in the Netherlands exported to foreign end-users, but also foreign owners have a large stake in Dutch shippers. As a result, part of the rents will always be distributed, or will 'leak' away, to foreign consumers and shippers (or their shareholders). These three observations together have three important implications. First, state ownership implies that much rent allocation is simply a matter of circulating money from one government sub-budget to the other. Second, given that the industry is imperfectly competitive, part of the rents will not be passed on to the end-consumers. Third, it is unavoidable that a substantial part of the rents are transferred abroad. A general conclusion for policy-makers is that market liberalization might not bring ex post what they expected ex ante. (author)

    The proliferation of linear infrastructure such as roads and railways is a major global driver of cumulative biodiversity loss. One strategy for reducing habitat loss associated with development is to encourage linear infrastructure providers and users to share infrastructure networks. We quantified the reductions in biodiversity impact and capital costs under linear infrastructure sharing of a range of potential mine to port transportation links for 47 mine locations operated by 28 separate companies in the Upper Spencer Gulf Region of South Australia. We mapped transport links based on least-cost pathways for different levels of linear-infrastructure sharing and used expert-elicited impacts of linear infrastructure to estimate the consequences for biodiversity. Capital costs were calculated based on estimates of construction costs, compensation payments, and transaction costs. We evaluated proposed mine-port links by comparing biodiversity impacts and capital costs across 3 scenarios: an independent scenario, where no infrastructure is shared; a restricted-access scenario, where the largest mining companies share infrastructure but exclude smaller mining companies from sharing; and a shared scenario where all mining companies share linear infrastructure. Fully shared development of linear infrastructure reduced overall biodiversity impacts by 76% and reduced capital costs by 64% compared with the independent scenario. However, there was considerable variation among companies. Our restricted-access scenario showed only modest biodiversity benefits relative to the independent scenario, indicating that reductions are likely to be limited if the dominant mining companies restrict access to infrastructure, which often occurs without policies that promote sharing of infrastructure. Our research helps illuminate the circumstances under which infrastructure sharing can minimize the biodiversity impacts of development. © 2017 The Authors. Conservation Biology published

  11. Promoting regional mobility

    DEFF Research Database (Denmark)

    Jensen, Anne

    Pricing of transport has been part of EU's common transport policy since this gained momentum in the early 1990s. Since then, it has been closely connected to the trans-European transport network (TEN-T) and to rising demands of efficient mobility systems at a local, regional and Community scale....... Development of pricing policies is contested at Community level and has taken place in a clash between different policy rationalities. Significantly though, the effects of the pricing policies are closely related to regional mobility systems, e.g. through financing large trans-border infrastructure projects...... and establishing common technical charging systems thus changing the conditions for regional mobility. This paper explores how policies of infrastructure pricing shape new ways of governing mobility which influences trans-border, regional policy-making. The key findings are that there is a tendency to include...

    Low cost transportation for people and goods is essential to the economic well-being of the nation. Until now, if the oil prices rise, the cost of transportation will automatically follow and most of the people suffering due to soaring prices of food and other items. Almost 100 percent of Indonesian transportation energy demand is supported by oil. Supply disruption - or even the threat of disruption - in the Middle East or elsewhere may lead to a shift in consumer prices and the cost of the industry in significant numbers. While costs in the energy sector, especially electricity in developed countries that also contribute significantly to support the transport sector, is much more stable and predictable. Energy requirements are so high in the transport sector tends to force people to seek the source and means of energy in other forms such as electricity or hydrogen that can match or exceed the performance of fuel oil. This paper aims to analyze the economics of energy price comparison to see the extent of the economic opportunities some kind of energy to play a significant role in the transport sector and the subsequent impact on the energy system. From the results obtained by the analysis that will be increasingly necessary role of nuclear energy and other specific energy as a source of electrical energy considering its economical aspects are relatively better.

  13. Hydrogen production from steam methane reforming and electrolysis as part of a near-term hydrogen infrastructure

    International Nuclear Information System (INIS)

    Roberts, K.

    2003-01-01

    Building a complete hydrogen infrastructure for a transportation system based on Fuel Cells (FC) and hydrogen is a risky and expensive ordeal, especially given that it is not known with complete certainty that Fuel Cells will indeed replace the gasoline ICE. But how can we expect the diffusion of an automotive technology if there is no infrastructure to support its fuel needs? This gives rise to a chicken and egg type problem. One way to get around this problem is to produce hydrogen when and where it is needed. This solves the problems of high costs associated with expensive pipeline distribution networks, the high energy-intensities associated with liquefaction of hydrogen and the high costs of cryogenic equipment. This paper will consider the advantages and disadvantages of two such hydrogen production mechanisms, namely, onsite production of hydrogen from Electrolysis and onsite production of hydrogen from Steam Methane Reforming (SMR). Although SMR hydrogen may be more economical due to the availability and low cost of methane, under certain market and technological conditions onsite electrolytic hydrogen can be more attractive. The paper analyses the final price of delivered hydrogen based on its sensitivity to market conditions and technology developments. (author)

  14. The integration of Price Responsive Demand into Regional Transmission Organization (RTO) wholesale power markets and system operations

    International Nuclear Information System (INIS)

    Centolella, Paul

    2010-01-01

    A number of states and utilities are pursuing demand response based on dynamic and time-differentiated retail prices and utility investments in Advanced Metering Infrastructure (AMI), often as part of Smart Grid initiatives. These developments could produce large amounts of Price Responsive Demand, demand that predictably responds to changes in wholesale prices. Price Responsive Demand could provide significant reliability and economic benefits. However, existing RTO tariffs present potential barriers to the development of Price Responsive Demand. Effectively integrating Price Responsive Demand into RTO markets and operations will require changes in demand forecasting, scarcity pricing reform, synchronization of scarcity pricing with capacity markets, tracking voluntary hedging by price responsive loads, and a non-discriminatory approach in curtailments in capacity emergencies. The article describes changes in RTO policies and systems needed incorporate Price Responsive Demand. (author)

    2006-12-01

    Today’s society relies greatly upon an array of complex national and international infrastructure networks such as transportation, utilities, telecommunication, and even financial networks. While modeling and simulation tools have provided insight into the behavior of individual infrastructure networks, a far less understood area is that of the interrelationships among multiple infrastructure networks including the potential cascading effects that may result due to these interdependencies. This paper first describes infrastructure interdependencies as well as presenting a formalization of interdependency types. Next the paper describes a modeling and simulation framework called CIMS© and the work that is being conducted at the Idaho National Laboratory (INL) to model and simulate infrastructure interdependencies and the complex behaviors that can result.

    2008-01-01

    The Australian coal industry is an export oriented industry, meeting world needs as a secure, reliable and competitive supplier of high quality coal. It is also the world's largest exporter, with 30 per cent of world coal market. An overview of the Australian coal industry and the impacts of coal infrastructure bottlenecks were addressed in this presentation, with particular reference to demurrage; shipping costs; lost profit and income for coal companies; costs to end users; lost royalties; lost income for infrastructure providers; and higher shipping costs. Perspectives from 2002 were illustrated in graph format, including thermal and metallurgical coal prices; forecast for world coal imports; and forecasted global demand versus actual demand. Other contributing factors to capacity constraints include the underperformance of coal infrastructure supply chains and investment issues. Australia's infrastructure response required a coordinated response between the federal government, state government, mining companies, shippers and buyers, port authorities, Australian Rail Track Corporation, coal terminal operators, and private and public rail freight operators. The presentation concluded with a discussion of the Australian infrastructure response, such as supply side improvement strategies, demand management strategies, and investment in increased infrastructure capacity. It was concluded that infrastructure issues must be addressed on a system wide basis. tabs., figs

    Full Text Available This paper offers a broad overview of road pricing from a social welfare perspective. I first examine two common objectives of road pricing: congestion management and profit making. My goal is to provide a guideline explaining how to promote a social-welfare-enhancing road pricing scheme. To this end, we should: (i consider and improve public transportation systems by providing more environment-friendly transport options; (ii include tolling profits in our welfare analysis (as opposed to what economists suggest since residents are the real owners of roads not users, and since some users are from outside the region and so might not be excluded from analysis; and (iii search for a holistic approach that takes into account system-wide impacts, disutility to users who change their travel behavior (i.e., switch to public transportation, shift their travel, or do not travel at all, and the impacts on land use, employment, and residents.

    Mechanisms linking changes to the environment with changes in physical activity are poorly understood. Insights into mechanisms of interventions can help strengthen causal attribution and improve understanding of divergent response patterns. We examined the causal pathways linking exposure to new transport infrastructure with changes in cycling to work. We used baseline (2009) and follow-up (2012) data (N=469) from the Commuting and Health in Cambridge natural experimental study (Cambridge, UK). Exposure to new infrastructure in the form of the Cambridgeshire Guided Busway was defined using residential proximity. Mediators studied were changes in perceptions of the route to work, theory of planned behaviour constructs and self-reported use of the new infrastructure. Outcomes were modelled as an increase, decrease or no change in weekly cycle commuting time. We used regression analyses to identify combinations of mediators forming potential pathways between exposure and outcome. We then tested these pathways in a path model and stratified analyses by baseline level of active commuting. We identified changes in perceptions of the route to work, and use of the cycle path, as potential mediators. Of these potential mediators, only use of the path significantly explained (85%) the effect of the infrastructure in increasing cycling. Path use also explained a decrease in cycling among more active commuters. The findings strengthen the causal argument that changing the environment led to changes in health-related behaviour via use of the new infrastructure, but also show how some commuters may have spent less time cycling as a result.

    2017-10-23

    For decades, the transportation system has been built to position the personal automobile at the pinnacle of mobility options. This prominence is strongly reflected in individual and population behaviors, and supported by coevolved transportation policy, social norms, funding, and physical structures. Such has been the status quo for the living memory of the U.S. population. However, with the advent of emergent, technologically driven mobility options, the transportation system is in an era of rapid and disruptive change. No longer is transportation infrastructure an externality predominantly composed of physical elements; it is also now a personalized interface carried in the pockets of the majority of the population. Perceptions of personal mobility are evolving, in large part because of the proliferation of smartphone technology and the related Internet of Things (IoT), which will become increasingly essential within future transportation systems. With the emergence of personalized mobility infrastructure, many intervention approaches to influence transportation behavior do not adequately acknowledge the complexity of the social/digital environment within which transportation decisions are made. Transportation decisions are influenced by multiple facets, including costs and benefits in time and money, but also by sociocultural elements shaped by social norms and diffusion of ideas. Understanding of factors that lead to transportation behaviors can help to identify incentives and leverage points whereby alternative choices may be most accepted by individuals, and which, if well coordinated, may lead to improved transportation energy outcomes. How can change be initiated to shift away from the transportation status quo? Is it possible to use technologically delivered incentives to produce meaningful changes in transportation behavior? What types of incentives and at what perceived value is necessary to induce changes in behavior? As transportation agencies look

  2. Comparison of Urban and Suburban Rail Transport in Germany and in the Czech Republic

    2014-06-01

    Full Text Available Rail transport is an environmentally friendly form of passenger transport which can be utilized effectively also in urban and suburban transport systems. The paper describes the urban and suburban rail transport system including comparison of selected Czech (Prague, Brno and Ostrava and German metropolitan regions (Munich, Nuremberg and Dresden. Its aim is to analyze the importance of various factors influencing the differences between the situation in Germany and in the Czech Republic. Therefore, the research question is whether these differences are primarily caused by a different liberalization stage, or whether they are a result of other factors such as available infrastructure, investment level, rail transport services budget, structure and activity of ordering bodies and coordinators or geographical context. The supply of city and suburban rail transport is quite good in Germany and in the Czech Republic, although trains in Munich, Nuremberg and Dresden run more frequently, faster and are better interconnected with car transport. German rail transport sector is at a higher stage of liberalization, and tendering procedures are the preferred selection method for contractor carriers. However, a degree of liberalization of the railway sector is not the key marker indicating a better standard of urban and suburban rail transport in Germany because it is the high standard which is achieved as the consequence of the professional activity of the ordering bodies and train service coordinators in combination with geographical conditions, available financial sources and effective transport infrastructure. On the other hand, the importance of liberalization cannot be totally overlooked as tenders are a tool for the ordering bodies to strongly affect the price and quality of transport services in their area. The supply of better quality and attractive transport to passengers could increase the usage of rail transport in metropolitan regions and could

    David, L.

    2003-07-01

    This article examines the problem of the price-cap regulation applied to the british gas transport. The RPI-X cap is a particular form of the price cap. This cap seems to be more remunerative for the regulatory firm than a cap calculated on the Laspeyres index because it authorizes a greater freedom of prices choice, to the prejudice of the consumers. Facing these perverse effects, Cowan proposed in 1997 a new system, not more satisfying. Another equation is analyzed in this article, proposed by Ofgem. Meanwhile this system presents no improvement of the consumers surplus facing the RPI-X cap. (A.L.B.)

    Full Text Available The infrastructure of vehicular networks plays a major role in realizing the full potential of vehicular communications. More and more vehicles are connected to the Internet and to each other, driving new technological transformations in a multidisciplinary way. Researchers in automotive/telecom industries and academia are joining their effort to provide their visions and solutions to increasingly complex transportation systems, also envisioning a myriad of applications to improve the driving experience and the mobility. These trends pose significant challenges to the communication systems: low latency, higher throughput, and increased reliability have to be granted by the wireless access technologies and by a suitable (possibly dedicated infrastructure. This paper presents an in-depth survey of more than ten years of research on infrastructures, wireless access technologies and techniques, and deployment that make vehicular connectivity available. In addition, we identify the limitations of present technologies and infrastructures and the challenges associated with such infrastructure-based vehicular communications, also highlighting potential solutions.

  9. Area price and demand response in a market with 25% wind power

    2011-01-01

    Denmark, east and west of the Great Belt are bidding areas with separate hourly area prices for the Nord Pool power exchange, covering four Nordic countries and parts of Germany. The share of wind power has now increased to 25% on an annual basis in western Denmark. This has a significant impact not only on the electricity wholesale prices, but also on the development of the market. Hourly market data are available from the website of Danish TSO from 1999. In this paper these data are analysed for the period 2004–2010. Electricity generators and customers may respond to hourly price variations, which can improve market efficiency, and a welfare gain is obtained. An important limitation for demand response is events of several consecutive hours with extreme values. The analysis in this paper is a summary and update of some of the issues covered by the EU RESPOND project. It shows that extreme events were few, and the current infrastructure and market organisation have been able to handle the amount of wind power installed so far. This recommends that geographical bidding area for the wholesale electricity market reflects external transmission constraints caused by wind power. - Highlights: ► More than 10 years of hourly electricity market data are available for western Denmark. ► Current infrastructure and market organisation could handle 25% wind power. ► Demand response to hourly electricity prices leads to limited welfare gain. ► Consecutive hours with high or low price, or high or low wind are relatively few.

  10. Regional Relative Price Disparities and Their Driving Forces

    2017-09-01

    Full Text Available This paper studies the long-run behavior of relative price dispersion among cities in Korea with a special emphasis on heterogeneous transitional patterns of price level dynamics. Formal statistical tests indicate considerable evidence for rejecting the null of relative price level convergence among the majority of cities over the sample period of 1985-2015. The analysis of gravity model suggests that the effect of transportation costs on intercity price level differentials is limited, while other socioeconomic factors, such as income, input factor prices, demographic structure, and housing price growth, play key roles in accounting for persistent regional price level disparities. Individual price levels are found to be better explained by a multiple-component model, and the deviations from PPP may be attributed to distinct stochastic common trends that are characterized by income and demographic structure.

The broad coverage provided by an upstream system recommends this approach over vehicle-maker based approaches, which would not cover emissions from heavy-duty vehicles and the aviation, marine and off-road sub-sectors. The on-road fleet approach unfairly and inefficiently burdens vehicle manufacturers with responsibility for emissions that they cannot control. A new vehicles approach would exclude emissions from vehicles on the road prior to program inception. The hybrid approach faces significant technical and political complications, and it is not clear that the approach would actually change behavior among vehicle makers and users, which is its main purpose. They also note that a trading system would fail to encourage many land use and infrastructure measures that affect VMT growth and GHG emissions. They recommend that this market failure be addressed by complementing the trading system with a program specifically targeting land use- and infrastructure-related activities. A key issue that must be addressed in designing a national GHG control strategy is whether or not it is necessary to guarantee GHG reductions from the transport sector. Neither an upstream system nor a downstream approach would do so, since both would direct capital to the least-cost abatement opportunities wherever they were found. They review two reasons why it may be desirable to force transportation sector reductions: first, that the long-term response to climate change will require reductions in all sectors; and second, the many ancillary benefits associated with transportation-related, and especially VMT-related, emissions reduction activities. If policy makers find it desirable to establish transportation

    Critical infrastructure networks, including transport, are crucial to the social and economic function of urban areas but are at increasing risk from natural hazards. Minimizing disruption to these networks should form part of a strategy to increase urban resilience. A framework for assessing the disruption from flood events to transport systems is presented that couples a high-resolution urban flood model with transport modelling and network analytics to assess the impacts of extreme rainfall events, and to quantify the resilience value of different adaptation options. A case study in Newcastle upon Tyne in the UK shows that both green roof infrastructure and traditional engineering interventions such as culverts or flood walls can reduce transport disruption from flooding. The magnitude of these benefits depends on the flood event and adaptation strategy, but for the scenarios considered here 3-22% improvements in city-wide travel times are achieved. The network metric of betweenness centrality, weighted by travel time, is shown to provide a rapid approach to identify and prioritize the most critical locations for flood risk management intervention. Protecting just the top ranked critical location from flooding provides an 11% reduction in person delays. A city-wide deployment of green roofs achieves a 26% reduction, and although key routes still flood, the benefits of this strategy are more evenly distributed across the transport network as flood depths are reduced across the model domain. Both options should form part of an urban flood risk management strategy, but this method can be used to optimize investment and target limited resources at critical locations, enabling green infrastructure strategies to be gradually implemented over the longer term to provide city-wide benefits. This framework provides a means of prioritizing limited financial resources to improve resilience. This is particularly important as flood management investments must typically exceed

    As part of the larger energy market deregulation program, the Dutch Office of Energy Regulation (DTe) has developed the habit to force the Dutch gas transport enterprise (Gas Transport Services GTS) to lower its prices. In this report, we simulate the welfare effects of a five per cent transport price reduction. DTe's key argument is that lower gas transport prices will benefit the end-user. Indeed, that might well be the case. However, at least three observations complicate matters substantially: Observation 1: government ownership. GTS is government -owned, and the dominant shipper (Gasunie Trade and Supply) is partly so (50 %). Hence, lost revenues from the gas transport business will all emerge at the debit side of the government's budget, and part of the shippers' rent returns in the government's pockets. Observation 2: imperfect competition. Firms enter into the competitive game to make profits. Shippers are not different. So, apart from in the extreme case of perfect competition (or, more generally, perfect contestability), part of the rents will end up in the pockets of the shippers, rather than the endconsumers. Observation 3: rent export. The Netherlands are not an isolated island in the European gas ocean. Not only is the majority of gas transported in the Netherlands exported to foreign end-users, but apart from that have foreign owners a large stake in Dutch shippers. As a result, given the fact that the Dutch industry is not autarktic, part of the rents will always be distributed, or will always 'leak' away, to foreign consumers and shippers (or their shareholders). These three observations together have three important implications. First, state ownership implies that much rent allocation is simply a matter of circulating money from one government sub-budget to the other (Observation 1). Second, given that the industry is imperfectly competitive, part of the rents will not be passed on to the endconsumers (Observation 2). Third, it is unavoidable

    The poultry commodity consumption and requirement is one of the main commodities that must be fulfilled in a region to maintain the availability of meat from poultry. Poultry commodity production is one of the production sectors that have a clean environment resistance. An increasing of poultry commodity generation production requires a smooth distribution to arrive at the processing. The livestock location as a commodity production is placed at a considerable far distance from residential and market locations. Zones that have poultry commodity production have an excess potential to supply other zones that are lacking in production to the consumption of these commodities. The condition of highway transportation infrastructure that is very diverse with the damage level availability in a zone has an influence in the supply and demand of poultry commodity requirement in the regional internal of Central Java province. In order to know the effect of highway transportation infrastructure condition toward the poultry commodity movement, demography factor and availability of freight vehicles will be reviewed to estimate the amount of poultry commodity movement generation production. Thus the poultry commodity consumption requirement that located in the internal - regional zone of central java province can be adequated from the zone. So it can be minimized the negative impacts that affect the environment at the zone in terms of comparison of the movement attraction and generation production at poultry commodity in Central Java.

    Full Text Available Price is a significant factor of competitiveness. Price is a complex issue and is determined by a variety of demand and supply factors. These factors also differ from industry to industry. The purpose of this article is to determine the factors that influence pricing in the South African accommodation sector. In order to generate proper data, a survey was conducted at various South African accommodation establishments that were obtained from the databases of the three major associations in the accommodation sector. Two-hundred and forty seven questionnaires completed by managers from accommodation establishments were used in this research. Principal component factor analyses with Varimax rotation in STATISTICA were carried out. These resulted in ten factors, namely environmental qualities, amenities, image, management factor, positioning, quality service factor, infrastructure service factor, location, marketing and product quality factor. The results revealed that the major factors in pricing are service quality, image and product quality. Consequently this article can be used to assist managers in pricing and in obtaining a better competitive position in the industry by revising management structures and marketing campaigns. Keywords and phrases: Tourism industry, price competitiveness, service quality, image, product quality, entrepreneur and factor analysis

    This paper reports that India continues to press oil and gas exploration and development and expansion of its petroleum sector infrastructure. One of the key moves is the government's decision to stage a fourth exploration bidding round, its most ambitious to date and one expected to elicit enthusiasm from international oil companies. At the same time, state oil companies Oil and Natural Gas Commission and Oil India Ltd. plan to maintain strong domestic E and D programs. ONGC is seeking more revenue to sustain India's ambitious oil and gas upstream plans. The state company has asked the government for a 50% hike in the price of domestic crude. The government currently pays ONGC and OIL only about $8.84/bbl, a price fixed in 1981. A jump of 50% in the domestic crude price would net ONGC another $1 billion/year in revenues, ONGC Chairman S.L. Khosla the. The government and other state companies also continue efforts to expand gas utilization and markets and match refining plans with market needs

    2017-02-01

    Full Text Available The growth rate for the Botswana economy has slowed down in recent years. This has been explained by weak global demand in minerals, subdued commodity prices and persistent electricity supply problems. The government is making efforts to diversify the economy to tap from other sources of growth. The government has come with two initiatives to boast growth: increasing expenditure on roads and improved generation of electricity. Literature has failed to agree on the causal linkage between growth and infrastructure development.  Previous studies employed different measures of infrastructure development and models resulting in conflicting findings. As a point of departure this study uses a log linear model and different measures of growth and infrastructure to examine the link between the two variables in the context of Botswana. Using vector error correction model and Ordinary Least Squares the study finds that long term economic growth is explained by both measures of infrastructure (electricity distribution and maintenance of roads. The impact of the former was more pronounced than the impact of the later. Evidence supports the infrastructure led growth hypothesis.

    Lake, Ron; Farley, Jim

    Geospatial data and geoprocessing techniques are now directly linked to business processes in many areas. Commerce, transportation and logistics, planning, defense, emergency response, health care, asset management and many other domains leverage geospatial information and the ability to model these data to achieve increased efficiencies and to develop better, more comprehensive decisions. However, the ability to deliver geospatial data and the capacity to process geospatial information effectively in these domains are dependent on infrastructure technology that facilitates basic operations such as locating data, publishing data, keeping data current and notifying subscribers and others whose applications and decisions are dependent on this information when changes are made. This chapter introduces the notion of infrastructure technology for the Geospatial Web. Specifically, the Geography Markup Language (GML) and registry technology developed using the ebRIM specification delivered from the OASIS consortium are presented as atomic infrastructure components in a working Geospatial Web.

  3. How to decarbonize the transport sector?

    2013-01-01

    This article investigates possible evolution pathways for the transport sector during the 21st century, globally and in Europe, under a climate change control scenario. We attempt to shed light on the question how the transport sector should best be decarbonized. We perform our study with the global bottom-up energy systems model TIAM-ECN, a version of the TIAM model that is broadly used for the purpose of developing energy technology and climate policy scenarios, which we adapted for analyzing in particular the transport sector. Given the global aggregated perspective of TIAM-ECN, that in its current version yields at every point in time a single CO 2 price for different forms of energy use across geographic regions and economic sectors, it generates a decarbonization process that for the transport sector occurs later in time than for the power sector. This merely reflects that emission reductions are generally cheaper for electricity production than for transportation, and that it is thus cost-minimizing to spend limited financial resources available for CO 2 emissions abatement in the power sector first. In our scenarios the use of hydrogen in internal combustion engines and fuel cells, rather than electricity as energy carrier and batteries to store it, gradually becomes the dominant transport technology. This outcome is in agreement with some recent publications but is at loggerheads with the current popularity of the electric car. Based on sensitivity analysis we conclude that even if the establishment of a hydrogen infrastructure proves about an order of magnitude more costly than modeled in our base case, electricity based transportation only broadly emerges if simultaneously also the costs of electric cars go down by at least 40% with respect to our reference costs. One of the explanations for why the electric car is today, by e.g. entrepreneurs, often considered the supposed winner amongst multiple future transportation options is that the decision

    -pay model would work to eliminate political influence, create revenue for infrastructure renewal, and facilitate an optimal allocation of infrastructure resources. All of this further helps maximise the benefits derived from public infrastructure. This model of infrastructure finance and provision could be further advanced and reinforced through the creation of provincial and federal bodies whose mandate would be to actively evaluate infrastructure investments in their respective jurisdictions, prioritizing funding for the most meritorious projects, and those offering the highest public return on investment. When projects are funded through taxation and access is not priced, there is often little or no incentive for individuals to make efficient use of them. The lack of direct accountability means individuals fail to use infrastructure judiciously and sparingly to preserve the life of public assets or prevent unnecessary congestion. Moreover, the lack of a clear sense of cost means governments do not know the true value that the public places on one type of infrastructure over another. Thus, government budgeting for such projects remains inefficient and skewed. The best level and mix of public infrastructure can only be determined when government and private providers can reliably establish user demands in a priced (efficient system. The current model of funding public infrastructure deprives users of infrastructure as well as government planners from vital information they need to make informed and efficient decisions. Both remain unclear on value for money, and costaccountability, but are bound by an innate aversion to increased tax-financing. Governments, fully cognizant of both consumer attitudes and the need to retain vote-getting power, thus swing between funding necessary infrastructure and allowing infrastructure deficits to grow. This paper advocates for a more efficient, accountable system with greater dependence on user-pay models and reinforced by and active

  6. Transport and environment: policy directions for Europe

    International Nuclear Information System (INIS)

    Tinch, R.

    2001-01-01

    Transport externalities are among the most important environmental problems affecting quality of life in Europe. Forecasts suggest that past environmental improvements may now be rolled back by traffic growth, and current traffic trends are not sustainable. The theory of environmental policy proposes pricing external costs at their marginal social costs as one solution. Although full marginal social cost pricing is impracticable, advances in tolling technology and environmental valuation mean that it is now a viable option to approximate such charging. There are signs that the European Commission and other bodies are starting to favour pricing over regulatory instruments. However, often overlooked is the potential for non-convexities in the transport sector or between transport and the rest of the economy. For example it may be that small increases in resources for public transport would not result in welfare gains, whereas large increases would. Non-convexities would mean that market forces under marginal social cost pricing might lead away from the optimal transport system. This is one reason why pricing instruments cannot in themselves be a panacea for transport externalities or bring about a sustainable transport system. (Author)

    Extending earlier seminal work, the author finds that locational spot price differences in an electric network provide the natural measure of the appropriate internodal transport charge. However, the problem of loop flow requires different economic intuition for interpreting the implications of spot pricing. The Direct Current model, which is the usual approximation for estimating spot prices, ignores reactive power effects; this approximation is best when thermal constraints create network congestion. However, when voltage constraints are problematic, the DC Load model is insufficient; a full AC Model is required to determine both real and reactive spot prices. 16 figs., 3 tabs., 22 refs

  9. ON PROBLEM OF REGIONAL WAREHOUSE AND TRANSPORT INFRASTRUCTURE OPTIMIZATION

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available The article suggests an approach of solving the problem of warehouse and transport infrastructure optimization in a region. The task is to determine the optimal capacity and location of the support network of warehouses in the region, as well as power, composition and location of motor fleets. Optimization is carried out using mathematical models of a regional warehouse network and a network of motor fleets. These models are presented as mathematical programming problems with separable functions. The process of finding the optimal solution of problems is complicated due to high dimensionality, non-linearity of functions, and the fact that a part of variables are constrained to integer, and some variables can take values only from a discrete set. Given the mentioned above complications search for an exact solution was rejected. The article suggests an approximate approach to solving problems. This approach employs effective computational schemes for solving multidimensional optimization problems. We use the continuous relaxation of the original problem to obtain its approximate solution. An approximately optimal solution of continuous relaxation is taken as an approximate solution of the original problem. The suggested solution method implies linearization of the obtained continuous relaxation and use of the separable programming scheme and the scheme of branches and bounds. We describe the use of the simplex method for solving the linearized continuous relaxation of the original problem and the specific moments of the branches and bounds method implementation. The paper shows the finiteness of the algorithm and recommends how to accelerate process of finding a solution.

  10. Business Models for Solar Powered Charging Stations to Develop Infrastructure for Electric Vehicles

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available Electric power must become less dependent on fossil fuels and transportation must become more electric to decrease carbon emissions and mitigate climate change. Increasing availability and accessibility of charging stations is predicted to increase purchases of electric vehicles. In order to address the current inadequate charging infrastructure for electric vehicles, major entities must adopt business models for solar powered charging stations (SPCS. These SPCS should be located in parking lots to produce electricity for the grid and provide an integrated infrastructure for charging electric vehicles. Due to the lack of information related to SPCS business models, this manuscript designs several models for major entities including industry, the federal and state government, utilities, universities, and public parking. A literature review of the available relevant business models and case studies of constructed charging stations was completed to support the proposals. In addition, a survey of a university’s students, staff, and faculty was conducted to provide consumer research on people’s opinion of SPCS construction and preference of business model aspects. Results showed that 69% of respondents would be more willing to invest in an electric vehicle if there was sufficient charging station infrastructure at the university. Among many recommendations, the business models suggest installing level 1 charging for the majority of entities, and to match entities’ current pricing structures for station use. The manuscript discusses the impacts of fossil fuel use, and the benefits of electric car and SPCS use, accommodates for the present gap in available literature on SPCS business models, and provides current consumer data for SPCS and the models proposed.

  12. Human initiated cascading failures in societal infrastructures.

    Directory of Open Access Journals (Sweden)

    Chris Barrett

    Full Text Available In this paper, we conduct a systematic study of human-initiated cascading failures in three critical inter-dependent societal infrastructures due to behavioral adaptations in response to a crisis. We focus on three closely coupled socio-technical networks here: (i cellular and mesh networks, (ii transportation networks and (iii mobile call networks. In crises, changes in individual behaviors lead to altered travel, activity and calling patterns, which influence the transport network and the loads on wireless networks. The interaction between these systems and their co-evolution poses significant technical challenges for representing and reasoning about these systems. In contrast to system dynamics models for studying these interacting infrastructures, we develop interaction-based models in which individuals and infrastructure elements are represented in detail and are placed in a common geographic coordinate system. Using the detailed representation, we study the impact of a chemical plume that has been released in a densely populated urban region. Authorities order evacuation of the affected area, and this leads to individual behavioral adaptation wherein individuals drop their scheduled activities and drive to home or pre-specified evacuation shelters as appropriate. They also revise their calling behavior to communicate and coordinate among family members. These two behavioral adaptations cause flash-congestion in the urban transport network and the wireless network. The problem is exacerbated with a few, already occurring, road closures. We analyze how extended periods of unanticipated road congestion can result in failure of infrastructures, starting with the servicing base stations in the congested area. A sensitivity analysis on the compliance rate of evacuees shows non-intuitive effect on the spatial distribution of people and on the loading of the base stations. For example, an evacuation compliance rate of 70% results in higher number

    According to this presentation, The oil shock of 1973 tripled the share of natural gas in the primary energy consumption in Western Europe. Power generation now emerges as the fastest growing market for gas. Under the impetus of the new measures to be implemented by the EU, as well as the willingness of governments and industrial consumers, the European gas market will gradually change. Price prospects represent the key issue of the new European model. On the one hand prices are likely to become more volatile, increasingly changing with the season. Long-term contract pricing formulas and competing prices may decouple the gas price from oil or petroleum product prices. On the other hand, as a clean energy source gas will register a sustained growth in demand. Gas will still require highly capitalistic infrastructure to reach the markets safely. 8 figs

    Saricks, C.L.; Singh, M.K.; Stammer, R.E. Jr.

    1988-06-01

    This study is concerned with the segments of the transportation system that include possible routings over public roads and private (or public) rail links, and waterway access (within 25 miles) from the gates of typical reactor sites to proximate links of what can be termed the national through-route system. These routings are by no means uniform throughout the United States. Local roads and rail links near reactor sites may be subject to a wide variety of jurisdictions for maintenance, repair, and inspection; may or may not (at present) qualify for federal assistance under the Federal-Aid Highway and related funding programs; may or may not meet accepted construction standards for facilities expected to bear heavy loads; and, perhaps most importantly for the spent-fuel transportation program, may be subject to occasional and currently unavoidable disruptions that could seriously impair shipment schedules. The overall objectives of the study are to describe a framework for identifying the characteristics of the near-site transportation networks of all existing nuclear power plants that could give rise to important shipment scheduling and programming constraints. These characteristics cover both transportation infrastructure and existing structural and environmental limitation, and define a scope and schedule for constructing a data base for the transportation networks surrounding all nuclear power plants. 6 refs., 4 figs., 8 tabs

  20. Transportation Infrastructure Impacts Evaluation: The Case of Egnatia Motorway in Greece

    Directory of Open Access Journals (Sweden)

    2014-05-01

    Full Text Available To expand GIS abilities to the consideration of decision criteria, OR/MS researchers strongly pronounce in favor of developing synergies between GIS and multicriteria decision making tools. The rationale of this integration is the GIS ability to store and manage and visualize geographically referenced data and the efficiency of Operational Research tools for modeling decision problems. As a result, MultiCriteria Spatial Decision Support Systems (MC-SDSS provide a consistent framework that allows alternatives’ ranking combining both spatial data and DMs preferences according to a selected decision rule. Regarding to their applicability in situations that involve classification, multiattribute decision models are considered as a very attractive procedure in urban and regional planning concerning the appraisal of transportation infrastructure construction. In the present a spatial multicriteria evaluation of the impacts derived by the realization of Egnatia Motorway is performed. Egnatia Motorway is considered one of the most significant interventions that have taken place in Greece during the early pre-Olympic Games period and up to the year 2007. With a length of 670 km, it crosses 12 prefectures starting from the Igoumenitsa Port, which provides links by boat to Italy, ending to Kipi in Evros (Greek-Turkish borders. It is a dual carriageway with two traffic lanes per direction with an overall construction cost of about 6b€. Aiming to enrich Northern Greece’s potential in transport industry and tourism, European Union has heavily invested in its construction. In the present paper an integration among GIS functionalities and multi-attribute decision making models such as Analytic Hierarchy Process (AHP and Ideal Point Methods is proposed in order to estimate the impacts provoked by the construction and operation of Egnatia Motorway in regional level.

    reduced carbon emissions are central to the design and optimization of future low carbon transport systems. Gaker et al (2011) suggest a framework, and provide insight into the willingness of transport consumers to pay for emission reductions of carbon dioxide from their personal transport choices within the context of other attributes of transport variables. The results of this study, although limited to a small demographic segment of the US population, demonstrate that people can integrate information on greenhouse gas emissions with other transport attributes including cost and time. Likewise, the research shows that the study group was willing to pay for reduction in greenhouse gas emissions associated with their transport choices. The study examined auto purchase choice, transport mode choice and transport route choice, which represent key decisions associated with transport that impact greenhouse gas emissions. Interestingly, they found that the study group was willing to pay for reductions in greenhouse gas emissions at a relatively consistent price across these transport choices. Clearly, the study results may not broadly apply to all demographics of users of transport, even in the study domain, due to the small demographic segment that was examined and the fact that the study was conducted in the laboratory. However, the methods used by Gaker et al (2011) are cause for optimism that future studies can obtain much needed mapping of transport preferences and willingness to pay for greenhouse gas emission reductions associated with personal transport choices. Although the Gaker et al (2011) study is directed at understanding the promotion of low carbon transport in the context of existing infrastructures, the ability of these studies to elucidate human behavior and preferences within the trade-offs of transport are critical to the design of future transport systems that seek to meet transport demand with constrained greenhouse gas emissions.

    Full Text Available Purpose. The purpose of the article is to develop a one- and two-element model of the fees calculation for the use of track infrastructure of Ukrainian railway transport. Methodology. On the basis of this one can consider that when planning the planned preventive track repair works and the amount of depreciation charges the guiding criterion is not the amount of progress it is the operating life of the track infrastructure facilities. The cost of PPTRW is determined on the basis of the following: the classification track repairs; typical technological processes for track repairs; technology based time standards for PPTRW; costs for the work of people, performing the PPTRW, their hourly wage rates according to the Order 98-Ts; the operating cost of machinery; regulated list; norms of expenditures and costs of materials and products (they have the largest share of the costs for repairs; railway rates; average distances for transportation of materials used during repair; standards of general production expenses and the administrative costs. Findings. The models offered in article allow executing the objective account of expenses in travelling facilities for the purpose of calculation of the proved size of indemnification and necessary size of profit, the sufficient enterprises for effective activity of a travelling infrastructure. Originality. The methodological bases of determination the fees (payments for the use of track infrastructure on one- and two-element base taking into account the experience of railways in the EC countries and the current transport legislation were grounded. Practical value. The article proposes the one- and two-element models of calculating the fees (payments for the TIF use, accounting the applicable requirements of European transport legislation, which provides the expense compensation and income formation, sufficient for economic incentives of the efficient operation of the TIE of Ukrainian railway transport.

    There are repeated calls to build better cycling paths in Australian cities if the proportion of people cycling is to increase. Yet the full range of transport, health, environmental and economic impacts of new cycling infrastructure and the extent to which observed changes are sustained is not well understood. The City of Sydney is currently building a new bicycle network, which includes a new bicycle path separated from road traffic in the south Sydney area. This protocol paper describes a comprehensive method to evaluate this new cycling infrastructure. A cohort of residents within two kilometres of the new bicycle path will be surveyed at baseline before a new section of bicycle path is built, and again 12 and 24 months later to assess changes in travel behaviour, sense of community, quality of life and health behaviours. Residents in a comparable area of Sydney that will not get a new separated bike path will act as a comparison group. At baseline a sub-set of residents who volunteer will also take a small GPS device with them for one week to assess travel behaviour. This research should contribute to the advancement in evaluation and appraisal methods for cycling projects.

    2016-01-01

    Full Text Available Recent flood events in Ireland and particularly in County Cork have caused significant disruption to health service provisions, interruption of water and power supplies, and damage to roads and other transportation infrastructure, affecting the lives of hundreds of thousands of people over a prolonged period of weeks. These events clearly reveal- the vulnerability of the critical infrastructure to flooding and the dependence of society on critical infrastructure. In order to reduce the flood vulnerability and increase the resilience of the critical infrastructure networks in the future, detailed evidence-based analysis and assessment is essential. To this end a case study has been carried out on Cork City which analyses this vulnerability as it was in 2009, and as it is currently, and identifies adaptation options to reduce the future vulnerability of critical infrastructure to flooding and to build a more resilient society. This paper describes the storyline approach and CIrcle tool and their application to Cork City which focused on the analysis of the flood vulnerability of critical infrastructure and the impacts of failure of the infrastructure for other critical functions and on society.

    Full Text Available The Danube Regions, especially the sub-national units of governance, must be ready to play an active role in spatial development policies. A precondition for this is good accessibility and the coordinated development of all transport systems in the Danube corridor. The main contribution of this paper is to provide a multi-criteria model for potential decision making related to the evaluation of transportation accessibility in Serbia’s Danube Corridor. Geographic Information Systems (GIS, based on maps, indicate the existing counties’ transport infrastructures inequities (between well-connected and isolated counties in terms of accessibility to central places. Through the research, relevant indicators have been identifi ed. This provides an outline of transportation perspectives regarding the development achieved and also fosters the increase of transportation accessibility in some peripheral Serbian Danube administrative units – counties (Nomenclature of Territorial Units for Statistics level 3 – NUTS 3.

    Full Text Available Rail transport is the second mode most used in the country, due to the low cost of transporting large volumes over long distances. Although there was no investment in the expansion for a long time, after privatization there was a resumption of maintenance and expansion of the railways, but it is far from achieving international quality and performance indices. The objective of this work was a study on the rail transport in the country, to raise the structure of the Brazilian railway network. For the development of this article, the method used was bibliographic research in books, articles and websites. Although the Brazilian railway network is just over 12% of the railroad network in the United States, after the privatization of the sector, growth has resumed. The Bioceanic, a railroad that will connect the Atlantic Ocean to the Pacific Ocean, will improve the flow of agricultural production to overseas

    The coal world experienced a true upheaval in the past five years World coal consumption went up 28 % between 2000 and 2005, as a result of the strong growth in Chinese demand. The growth should continue in the coming years: electrical plant builders' orders are mainly for coal. The regained interest in coal is based on the constraints experienced by competing energies (increase in oil and natural gas prices, geopolitical uncertainties, supply difficulties) and by the abundant reserves of coal in the world and the competitiveness of its price. The strong growth in world coal demand comes with a change in rules governing steam coal trading. While long term bilateral agreements were most common until the late nineties, there has been a true revolution in coal marketing since 2000: spot contracts, stock exchange emergence and futures contracts, price indexes. In a few years, the steam coal market has become a true commodities market, overtaking many more goods. The price of coal has also gone through strong variations since 2003. Whereas the price had been stable for decades, in 2004 the strong increase in China' s demand for coal and iron ore resulting in transport shortage, caused a strong increase in CAF coal prices. Since then, prices have gone down, but remain higher than the Eighties and Nineties levels. In spite of the increase, coal remains available at more competitive prices than its competing energies.

  15. The Role of the Transport System in the National Management of Life Quality

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available The aim of the article is to analyze the development prospects of transport system in Ukraine as a lever for national economic development capable of providing a sustainable quality of life and to search for mechanisms of their activation in national development. Transport is one of the leading sectors of material production, it participates in the formation of its branch structure, placement of production capacity and price formation. Through the economic channels the transport industry affects all indicators of life quality creating benefits for economic growth of the region and the country, developing national infrastructure. The transport industry performs a range of services to improve the life quality of the population: providing access to all members of society to socio-economic infrastructure by increasing the degree of transport accessibility, increasing labor force mobility, increasing availability of any objects, simplifying the implementation of many vital processes and expanding opportunities for social interaction. The quality of the social environment formation depends on the operation quality and development level of the transport system. A higher mobility and saving of time as the most important resource of modern time create more opportunities for human development. But the transport system also increases the risk level and risk of human existence because of environmental degradation, technogenity and increasing accident rates. The potential of the transport system development in Ukraine, which, provided the right management decisions, can be implemented as a competitive advantage, should include a favorable geographical position. In order to give the transport development a dynamic nature, it is necessary to combine technological and technical renewal of the industry with the improvement of the state regulation system on the basis of forming innovative transport strategies. It is this approach that not only will allow solving

  16. Essays on the Impacts of Geography and Institutions on Access to Energy and Public Infrastructure Services

    Science.gov (United States)

    Archibong, Belinda

    While previous literature has emphasized the importance of energy and public infrastructure services for economic development, questions surrounding the implications of unequal spatial distribution in access to these resources remain, particularly in the developing country context. This dissertation provides evidence on the nature, origins and implications of this distribution uniting three strands of research from the development and political economy, regional science and energy economics fields. The dissertation unites three papers on the nature of spatial inequality of access to energy and infrastructure with further implications for conflict risk , the historical institutional and biogeographical determinants of current distribution of access to energy and public infrastructure services and the response of households to fuel price changes over time. Chapter 2 uses a novel survey dataset to provide evidence for spatial clustering of public infrastructure non-functionality at schools by geopolitical zone in Nigeria with further implications for armed conflict risk in the region. Chapter 3 investigates the drivers of the results in chapter 2, exploiting variation in the spatial distribution of precolonial institutions and geography in the region, to provide evidence for the long-term impacts of these factors on current heterogeneity of access to public services. Chapter 4 addresses the policy implications of energy access, providing the first multi-year evidence on firewood demand elasticities in India, using the spatial variation in prices for estimation.

    Data and modeling infrastructure is becoming increasingly accessible to water scientists. HydroShare is a collaborative environment that currently offers water scientists the ability to access modeling and data infrastructure in support of data intensive modeling and analysis. It supports the sharing of and collaboration around "resources" which are social objects defined to include both data and models in a structured standardized format. Users collaborate around these objects via comments, ratings, and groups. HydroShare also supports web services and cloud based computation for the execution of hydrologic models and analysis and visualization of hydrologic data. However, the quantity and variety of data and modeling infrastructure available that can be accessed from environments like HydroShare is increasing. Storage infrastructure can range from one's local PC to campus or organizational storage to storage in the cloud. Modeling or computing infrastructure can range from one's desktop to departmental clusters to national HPC resources to grid and cloud computing resources. How does one orchestrate this vast number of data and computing infrastructure without needing to correspondingly learn each new system? A common limitation across these systems is the lack of efficient integration between data transport mechanisms and the corresponding high-level services to support large distributed data and compute operations. A scientist running a hydrology model from their desktop may require processing a large collection of files across the aforementioned storage and compute resources and various national databases. To address these community challenges a proof-of-concept prototype was created integrating HydroShare with RADII (Resource Aware Data-centric collaboration Infrastructure) to provide software infrastructure to enable the comprehensive and rapid dynamic deployment of what we refer to as "collaborative infrastructure." In this presentation we discuss the

    Ramaswami, A.

    2016-12-01

    Urban infrastructure - broadly defined to include the systems that provide water, energy, food, shelter, transportation-communication, sanitation and green/public spaces in cities - have tremendous impact on the environment and on human well-being (Ramaswami et al., 2016; Ramaswami et al., 2012). Aggregated globally, these sectors contribute 90% of global greenhouse gas (GHG) emissions and 96% of global water withdrawals. Urban infrastructure contributions to such impacts are beginning to dominate. Cities are therefore becoming the action arena for infrastructure transformations that can achieve high levels of service delivery while reducing environmental impacts and enhancing human well-being. Achieving sustainable urban infrastructure transitions requires: information about the engineered infrastructure, and its interaction with the natural (ecological-environmental) and the social sub-systems In this paper, we apply a multi-sector, multi-scalar Social-Ecological-Infrastructural Systems framework that describes the interactions among biophysical engineered infrastructures, the natural environment and the social system in a systems-approach to inform urban infrastructure transformations. We apply the SEIS framework to inform water and energy sector transformations in cities to achieve environmental and human health benefits realized at multiple scales - local, regional and global. Local scales address pollution, health, wellbeing and inequity within the city; regional scales address regional pollution, scarcity, as well as supply risks in the water-energy sectors; global impacts include greenhouse gas emissions and climate impacts. Different actors shape infrastructure transitions including households, businesses, and policy actors. We describe the development of novel cross-sectoral strategies at the water-energy nexus in cities, focusing on water, waste and energy sectors, in a case study of Delhi, India.

    2004-01-01

    The study reported in this paper is part of an OECD project with several case studies in different countries. The purpose of the project was to look for possible ways to reduce the environmental impact of transport to a level which is compatible with sustainability. The participants in the case studies agreed upon quantifying criteria for carbon dioxide, nitrogen oxides and volatile organic compounds, which should describe environmentally sustainable transport (EST), and each case study constructed a business-as-usual scenario and three EST scenarios, considering the period from 1990 to 2030. Each EST scenario should meet the criteria in a backcasting effort, EST1 looking for solely technical solutions, EST2 restricting and shifting transport volumes while ignoring technological progress, and EST3 combining components of both strategies. In the German case study criteria were additionally quantified for particulate matter, noise and land-take for transport purposes. The German EST1 scenario is based on hybrid electric hypercars, hydrogen for public transport, freight and aviation, and electricity from renewable sources. In the EST2 scenario total transport activity for passenger and freight transport had to be reduced by 40% and 25% respectively, compared to 1990 in order to meet the criteria. In the EST3 scenario, while highly energy efficient conventional propulsion systems and engines were used, total passenger transport decreased only slightly and freight transport even increased. Implementation measures were then defined on the basis of the EST3 scenario. Emission regulation, fuel tax, and road pricing for heavy duty vehicles were the key features in order to achieve EST in this case study. They were complemented by additional sets of measures, designed to prevent urban sprawl, diminish freight traffic growth, increase liveability of towns, improve the infrastructure and service conditions of alternative modes as well as provide energy supply by regenerative

    2015-01-01

    Full Text Available Rapid development of urbanization and automation has resulted in serious urban traffic congestion and air pollution problems in many Chinese cities recently. As a traffic demand management strategy, congestion pricing is acknowledged to be effective in alleviating the traffic congestion and improving the efficiency of traffic system. This paper proposes an urban traffic congestion pricing model based on the consideration of transportation network efficiency and environment effects. First, the congestion pricing problem under multimode (i.e., car mode and bus mode urban traffic network condition is investigated. Second, a traffic congestion pricing model based on bilevel programming is formulated for a dual-mode urban transportation network, in which the delay and emission of vehicles are considered. Third, an improved mathematical algorithm combining successive average method with the genetic algorithm is proposed to solve the bilevel programming problem. Finally, a numerical experiment based on a hypothetical network is performed to validate the proposed congestion pricing model and algorithm.

  10. CLUB FORMATION MECHANISM FOR TRANSPORT-COMMUNITY CREDIT CARDS

    Science.gov (United States)

    Ding, Yue; Kobayashi, Kiyoshi; Nishida, Junji; Yoshida, Mamoru

    In this paper, the roles of transport-community cards jointly issued by a public transport firm and retails are investigated as a means to vitalize an obsolescence shopping center located in a middle of a city. When both the price of goods supplied by the retails and the transport fares affect the consumers' behavior, there exist pecuniary externality between the behaviors of the retails and transport firms. The introduction of a transport-community cards system enables to integrate a basket of goods and transport service into a single commodity; thus, the pecuniary externality can be internalized by price coordination. In addition, the paper clarifies theoretically that the transport firm initiatively decides the price of the transportation service and the retails transfer their incomes to the transport firm so that they are induced to jointly issue the transport-community cards.

    Full Text Available Large and medium-size transport infrastructure shall increasingly cope with acceptability-related problems. This is due to the lack of confidence that nowadays characterises the relations between public administrations and their citizens, as well as between citizens and the project promoters. Moreover, the subjects that take advantage from the project implementation and those not often do not coincide, whereas the latter are not compensated for the damages they bear. A sound cost-benefit analysis supporting the entire decision-making process may be a valuable tool for fostering the dialogue with all concerned subjects, provided that a set of basic conditions is met. Firstly, cost-benefit analysis has to be credible as far as the effects generated by the project are concerned. Therefore, it shall: (i secure transparency of: results achieved by the evaluation (including the assumptions and criteria that led to such results, and procedures embedded into the evaluation process; (ii be performed by independent evaluators rather than those sponsoring the project; (iii be as much robust as possible, and finally (iv deliver structured and thorough risk analyses. In order to reinforce credibility and soundness of the analysis and the evaluations undertaken, previous project experiences shall be duly taken into account, which implies fine-tuning ex-ante evaluations upon the basis of the results obtained by ex-post analysis of projects already implemented. Additionally, the evaluation shall be dynamic, as it shall back since the very beginning the whole process of infrastructure designing, and until the project is finalised. Transparency of such process is then a key pre-requisite.\tThe second condition refers to the fact that stakeholders interested into the project shall be actively involved into the planning process. Further major token is that the economic evaluation at the level of approximation featuring the various steps of the project cycle feeds

  14. Transportation Energy Futures Series: Non-Cost Barriers to Consumer Adoption of New Light-Duty Vehicle Technologies

    Energy Technology Data Exchange (ETDEWEB)

    Stephens, T.

    2013-03-01

    Consumer preferences are key to the adoption of new vehicle technologies. Barriers to consumer adoption include price and other obstacles, such as limited driving range and charging infrastructure; unfamiliarity with the technology and uncertainty about direct benefits; limited makes and models with the technology; reputation or perception of the technology; standardization issues; and regulations. For each of these non-cost barriers, this report estimates an effective cost and summarizes underlying influences on consumer preferences, approximate magnitude and relative severity, and assesses potential actions, based on a comprehensive literature review. While the report concludes that non-cost barriers are significant, effective cost and potential market share are very uncertain. Policies and programs including opportunities for drivers to test drive advanced vehicles, general public outreach and information programs, incentives for providing charging and fueling infrastructure, and development of technology standards were examined for their ability to address barriers, but little quantitative data exists on the effectiveness of these measures. This is one in a series of reports produced as a result of the Transportation Energy Futures project, a Department of Energy-sponsored multi-agency effort to pinpoint underexplored strategies for reducing GHGs and petroleum dependence related to transportation.

  19. Diluent and bitumen, an uneasy mix : considerations for treating, blending, transportation, marketing and refining

    Energy Technology Data Exchange (ETDEWEB)

    Todd, C. [Connacher Oil and Gas Ltd., Calgary, AB (Canada)

    2009-07-01

    This presentation evaluated several issues regarding the use of diluent as a blending agent with Canadian bitumen. Heavy and viscous crude oils are commonly diluted with condensates and gasolines. This improves field processing, transportability in pipelines and acceptability in markets and refineries. The demand for such diluent is increasing because of the large amounts of heavy oil and bitumen currently produced in Canada. The current tenable price of diluents has meant that a wide range of diluent sources and components are finding their way into the Canadian diluent supply stream. This has raised concerns regarding diluent performance and the affect on blended crude oils. The cost of diluent is among the most controllable expense associated with most bitumen production projects. Market factors were considered in this presentation, such as supply demand; price and infrastructure; operational processing and blending issues; diluent quality and component variability; and downstream issues such as refinery processing and production. tabs., figs.

    Budzynski, Marcin; Jamroz, Kazimierz; Kustra, Wojciech; Michalski, Lech; Gaca, Stanislaw

    2017-10-01

    The objective of road safety infrastructure management is to ensure that when roads are planned, designed, built and used road risks can be identified, assessed and mitigated. Road transport safety is significantly less developed than that of rail, water and air transport. The average individual risk of being a fatality in relation to the distance covered is thirty times higher in road transport that in the other modes. This is mainly because the different modes have a different approach to safety management and to the use of risk management methods and tools. In recent years Poland has had one of the European Union’s highest road death numbers. In 2016 there were 3026 fatalities on Polish roads with 40,766 injuries. Protecting road users from the risk of injury and death should be given top priority. While Poland’s national and regional road safety programmes address this problem and are instrumental in systematically reducing the number of casualties, the effects are far from the expectations. Modern approaches to safety focus on three integrated elements: infrastructure measures, safety management and safety culture. Due to its complexity, the process of road safety management requires modern tools to help with identifying road user risks, assess and evaluate the safety of road infrastructure and select effective measures to improve road safety. One possible tool for tackling this problem is the risk-based method for road infrastructure safety management. European Union Directive 2008/96/EC regulates and proposes a list of tools for managing road infrastructure safety. Road safety tools look at two criteria: the life cycle of a road structure and the process of risk management. Risk can be minimized through the application of the proposed interventions during design process as reasonable. The proposed methods of risk management bring together two stages: risk assessment and risk response occurring within the analyzed road structure (road network, road

    2017-10-01

    Sedimentary properties territory Tura-Pyshma interfluve, where Tyumen is located are determined by the general course of ancient and especially the newest tectonic movements. Active development of the transport network on the territory of the Tour-Pyshma interfluve has created the need for a contemporary study of regional peculiarities of grounds. This will allow you to create roads with the quality meet the international standards. The use of average values of indicators of the properties of silty-clay soils during the development of the transport infrastructure projects of the city of Tyumen and its environs is ineffective due to the genetic characteristics of the rocks located at the depth of 1.5-5.0 meters. Detailed analysis showed that the studied soil belongs to the covering carbonate loams and clays, differing in its characteristics from loess-like sediments of the European part of Russia. The thickness of the covering rocks is not more than 5 meters. It’s low-carbonate, non-saline and often has a layered structure. The upper three meters of sediments contain the minimum quantity of water-soluble salts (dry residue less than 0.1%). Studied covering loams are characterized by favorable physical properties: the density of the bulk and the particle is 1.44 to 1.62 and 2.70-2.78 g/cm3, respectively. Water permeability is high - the filtration coefficient varies from 3.4 to 6.4 m/day, the minimum water velocity observed in the clay types of soil. The presence of sand layers adversely affects the permeability of soil. Therefore, the design and construction of transport infrastructure of the city and the surrounding territories it is necessary to consider regional features of grounds.

  4. Modeling Hydrogen Refueling Infrastructure to Support Passenger Vehicles †

    2018-05-01

    Full Text Available The year 2014 marked hydrogen fuel cell electric vehicles (FCEVs first becoming commercially available in California, where significant investments are being made to promote the adoption of alternative transportation fuels. A refueling infrastructure network that guarantees adequate coverage and expands in line with vehicle sales is required for FCEVs to be successfully adopted by private customers. In this paper, we provide an overview of modelling methodologies used to project hydrogen refueling infrastructure requirements to support FCEV adoption, and we describe, in detail, the National Renewable Energy Laboratory’s scenario evaluation and regionalization analysis (SERA model. As an example, we use SERA to explore two alternative scenarios of FCEV adoption: one in which FCEV deployment is limited to California and several major cities in the United States; and one in which FCEVs reach widespread adoption, becoming a major option as passenger vehicles across the entire country. Such scenarios can provide guidance and insights for efforts required to deploy the infrastructure supporting transition toward different levels of hydrogen use as a transportation fuel for passenger vehicles in the United States.

    Road authorities, freight, and logistic industries face a multitude of challenges in a world changing at an ever growing pace. While globalization, changes in technology, demography, and traffic, for instance, have received much attention over the bygone decades, climate change has not been treated with equal care until recently. However, since it has been recognized that climate change jeopardizes many business areas in transport, freight, and logistics, research programs investigating future threats have been initiated. One of these programs is the Conference of European Directors of Roads' (CEDR) Transnational Research Programme (TRP), which emerged about a decade ago from a cooperation between European National Road Authorities and the EU. This paper presents findings of a CEDR project called CliPDaR, which has been designed to answer questions from road authorities concerning climate-driven future threats to transport infrastructure. Pertaining results are based on two potential future socio-economic pathways of mankind (one strongly economically oriented "A2" and one more balanced scenario "A1B"), which are used to drive global climate models (GCMs) producing global and continental scale climate change projections. In order to achieve climate change projections, which are valid on regional scales, GCM projections are downscaled by regional climate models. Results shown here originate from research questions raised by European Road Authorities. They refer to future occurrence frequencies of severely cold winter seasons in Fennoscandia, to particularly hot summer seasons in the Iberian Peninsula and to changes in extreme weather phenomena triggering landslides and rutting in Central Europe. Future occurrence frequencies of extreme winter and summer conditions are investigated by empirical orthogonal function analyses of GCM projections driven with by A2 and A1B pathways. The analysis of future weather phenomena triggering landslides and rutting events requires

  7. Taking the mystery out of gasoline prices

    Gasoline price variations in different markets of Canada are primarily driven by market forces, not necessarily by costs, according to a petroleum valuation consultant of the Newfoundland Department of Mines and Energy. Market forces include wholesale prices, the number and efficiency of stations in an area, companies' marketing strategies and customer buying preferences. Prices can be affected by any one of these forces at any time. The prediction is that wholesale prices will continue to be volatile in the next few months as the market adjusts to the changes in crude oil prices determined by OPEC as well as the summer season for gasoline. Changes in crude oil prices are usually reflected in the price of gasoline at the pump, although they do not necessarily move together. Demand which is an important factor in price, is cyclical in both the US and Canada, being lowest in the first quarter of the year, picking up during the second and third quarters with increased driving during good weather, and usually declining again in the fourth quarter with the onset of colder weather. Taxes are also a very significant component of the retail price of gasoline; in July 1998 the combined federal and provincial taxes accounted for 54 per cent of the average retail price of regular unleaded gasoline in Canada. Refining and marketing costs, the distance gasoline has to be transported to market, also influence prices at the pump

    Indication value-based pricing (IBP) has been proposed in the United States as a tool to capture the differential value of drugs across indications or patient groups and is in the early phases of implementation. In Europe, no major country has experimented with IBP or is seriously discussing its use. We assessed how the reimbursement and pricing environment allows for IBP in seven European countries, evaluating both incentives and hurdles. In price setting countries such as France and Germany, the Health Technology Assessment and pricing process already accounts for differences of value across indications. In countries where differential value drives coverage decisions such as the United Kingdom and Sweden, IBP is likely to be used, at least partially, but not in the short-term. Italy is already achieving some form of differential value through managed entry agreements, whereas in Spain the electronic prescription system provides the infrastructure necessary for IBP but other hurdles exist.

    Full Text Available The study assessed allocation, criteria and allotment effectiveness of performance risks in Build- Operate-Transfer (BOT transportation infrastructure in Nigeria using Lagos Infrastructure Project (LIP as a case study. LIP is the only BOT-procured tolled road that has attained ‘operate’ stage of BOT cycle in Nigeria. It revealed that more operating risks were actually allocated to the concessionaire than the grantor and most of the risks were preferred retained by the allottee. Significant fraction of the risks was effectively allocated between the concessionaire and grantor except those that involve close interface between participants. While grantor rated nine risks high and seven risks very high; the concessionaire assessed nine risks to be high and five risks to be very high; the grantor rated the effectiveness level to be seventy three per cent and the concessionaire assessed it to be sixty four per cent. The study recommended that the evolving knowledge from Lagos Infrastructure Project (LIP should be documented to guide future BOT transactions in Nigeria.

  13. Oil prices in a new light

    International Nuclear Information System (INIS)

    Fesharaki, F.

    1994-01-01

    For a clear picture of how oil prices develop, the author steps away from the price levels to which the world is accustomed, and evaluates scientifically. What makes prices jump from one notch to another? The move results from a political or economic shock or the perception of a particular position by the futures market and the media. The shock could range from a war or an assassination to a promise of cooperation among OPEC members (when believed by the market) or to speculation about another failure at an OPEC meeting. In the oil market, only a couple of factual figures can provide a floor to the price of oil. The cost of production of oil in the Gulf is around $2 to $3/bbl, and the cost of production of oil (capital and operating costs) in key non-OPEC areas is well under $10/bbl. With some adjustments for transport and quality, a price range of $13/bbl to $16/bbl would correspond to a reasonable sustainable floor price. The reason for prices above the floor price has been a continuous fear of oil supply interruptions. That fear kept prices above the floor price for many years. The fear factor has now almost fully disappeared. The market has gone through the drama of the Iranian Revolution, the Iran-Iraq war, the tanker war, the invasion of Kuwait, and the expulsions of the Iraqis. And still the oil flowed -- all the time. It has become abundantly clear that fears above the oil market were unjustified. Everyone needs to export oil, and oil will flow under the worst circumstances. The demise of the fear factor means that oil prices tend toward the floor price for a prolonged period

    The ambitious target of 60% reduction in greenhouse gas emissions by 2050 requires transformation of the transport system in Europe. Decarbonising transport calls for the use of less and cleaner energy, and more efficient use of modern transport infrastructure and services. These strategic targets in EU policy are supported by substantial investment in research to develop innovative and sustainable solutions in efficient use of transport infrastructure and services, more energy-efficient transport, and use of alternative fuels and propulsion systems. This Policy Brochure, which is produced by the Transport Research and Innovation Portal (TRIP), highlights the contribution of research and innovation in meeting the EU targets on CO2 emission reduction in the transport system.

  1. Natural gas and CO2 price variation: impact on the relative cost-efficiency of LNG and pipelines.

    Science.gov (United States)

    Ulvestad, Marte; Overland, Indra

    2012-06-01

    THIS ARTICLE DEVELOPS A FORMAL MODEL FOR COMPARING THE COST STRUCTURE OF THE TWO MAIN TRANSPORT OPTIONS FOR NATURAL GAS: liquefied natural gas (LNG) and pipelines. In particular, it evaluates how variations in the prices of natural gas and greenhouse gas emissions affect the relative cost-efficiency of these two options. Natural gas is often promoted as the most environmentally friendly of all fossil fuels, and LNG as a modern and efficient way of transporting it. Some research has been carried out into the local environmental impact of LNG facilities, but almost none into aspects related to climate change. This paper concludes that at current price levels for natural gas and CO 2 emissions the distance from field to consumer and the volume of natural gas transported are the main determinants of transport costs. The pricing of natural gas and greenhouse emissions influence the relative cost-efficiency of LNG and pipeline transport, but only to a limited degree at current price levels. Because more energy is required for the LNG process (especially for fuelling the liquefaction process) than for pipelines at distances below 9100 km, LNG is more exposed to variability in the price of natural gas and greenhouse gas emissions up to this distance. If the prices of natural gas and/or greenhouse gas emission rise dramatically in the future, this will affect the choice between pipelines and LNG. Such a price increase will be favourable for pipelines relative to LNG.

    Transportation infrastructure tremendously affects the quality of life for urban residents, influences public and mental health, and shapes social relations. Historically, the topic is rich with social and political controversy and the resultant transit systems in the United States cause problems for minority residents and issues for the public. Environmental justice frameworks provide a means to identify and address harms that affect marginalized groups, but environmental justice has limits that cannot account for the mainstream population. To account for this condition, I employ a complex moral assessment measure that provides a way to talk about harms that affect the public.

    Infrastructure development does not only affect the economic aspect, but also social and environmental, those are the main dimensions of sustainable development. Many aspects and actors involved in urban infrastructure development requires a comprehensive and integrated policy towards sustainability. Therefore, it is necessary to formulate an infrastructure development policy that considers various dimensions of sustainable development. The main objective of this research is to formulate policy of sustainable infrastructure development. In this research, urban infrastructure covers transportation, water systems (drinking water, storm water, wastewater), green open spaces and solid waste. This research was conducted in Bandarlampung City. This study use a comprehensive modeling, namely the Multi Dimensional Scaling (MDS) with Rapid Appraisal of Infrastructure (Rapinfra), it uses of Analytic Network Process (ANP) and it uses system dynamics model. The findings of the MDS analysis showed that the status of Bandarlampung City infrastructure sustainability is less sustainable. The ANP analysis produces 8 main indicators of the most influential in the development of sustainable infrastructure. The system dynamics model offered 4 scenarios of sustainable urban infrastructure policy model. The best scenario was implemented into 3 policies consist of: the integrated infrastructure management, the population control, and the local economy development.

    The primary objective of this Advanced Mission Design Program is to define the general characteristics and phased evolution of a near-Earth space infrastructure. The envisioned foundation includes a permanently manned, self-sustaining base on the lunar surface, a space station at the Libration Point between earth and the moon (L1), and a transportation system that anchors these elements to the Low Earth Orbit (LEO) station. The implementation of this conceptual design was carried out with the idea that the infrastructure is an important step in a larger plan to expand man's capabilities in space science and technology. Such expansion depends on low cost, reliable, and frequent access to space for those who wish to use the multiple benefits of this environment. The presence of a cislunar space infrastructure would greatly facilitate the staging of future planetary missions, as well as the full exploration of the lunar potential for science and industry. The rationale for, and a proposed detailed scenario in support of, the cislunar space infrastructure are discussed.

  10. How to decarbonize the transport sector?

    Van der Zwaan, B.; Keppo, I. [Policy Studies Department, Energy research Center of the Netherlands ECN, Amsterdam (Netherlands); Johnsson, F. [Department of Energy and Environment, Chalmers University of Technology, Goeteborg (Sweden)

    2013-10-15

    This article investigates possible evolution pathways for the transport sector during the 21st century, globally and in Europe, under a climate change control scenario. We attempt to shed light on the question how the transport sector should best be decarbonized. We perform our study with the global bottom-up energy systems model TIAM-ECN, a version of the TIAM (TIMES Integrated Assessment Model) model that is broadly used for the purpose of developing energy technology and climate policy scenarios, which we adapted for analyzing in particular the transport sector. Given the global aggregated perspective of TIAM-ECN, that in its current version yields at every point in time a single CO2 price for different forms of energy use across geographic regions and economic sectors, it generates a decarbonization process that for the transport sector occurs later in time than for the power sector. This merely reflects that emission reductions are generally cheaper for electricity production than for transportation, and that it is thus cost-minimizing to spend limited financial resources available for CO2 emissions abatement in the power sector first. In our scenarios the use of hydrogen in internal combustion engines and fuel cells, rather than electricity as energy carrier and batteries to store it, gradually becomes the dominant transport technology. This outcome is in agreement with some recent publications but is at loggerheads with the current popularity of the electric car. Based on sensitivity analysis we conclude that even if the establishment of a hydrogen infrastructure proves about an order of magnitude more costly than modeled in our base case, electricity based transportation only broadly emerges if simultaneously also the costs of electric cars go down by at least 40% with respect to our reference costs. One of the explanations for why the electric car is today, by e.g. entrepreneurs, often considered the supposed winner amongst multiple future transportation

  11. Research on Price of Railway Freight Based on Low-Carbon Economy

    Directory of Open Access Journals (Sweden)

    Fenling Feng

    2016-01-01

    Full Text Available Transportation is one of the major energy consumption and carbon emission industries. Railway transport is a typical low-carbon transport. To accelerate the green low-carbon transportation development and improve the railway market share, this paper defines the concept of carbon saving profit to study the price of railway freight after the government functions were separated from railway enterprise management. First, taking full account of market factors and on the principle of utility maximization and maximum likelihood method, the sharing ratio model of transportation modes is established. Then consideration is given to both the profit of railway enterprises and social benefits, and income maximization model of railway freight based on low-carbon economy is established. The model can scientifically guide the transportation users who prefer to use resource-saving and environmental-friendly transportation modes, optimize transportation structure, and comprehensively improve the efficiency of transportation system. Finally, case analysis is conducted to verify the rationality and validity of the model, and reference for the rail freight pricing is provided.

  12. Fair and efficient prices in traffic. Propositions on price policy for the sustainable development of traffic in Switzerland

    International Nuclear Information System (INIS)

    Maibach, M.; Ott, W.; Schreyer, Ch.

    2000-01-01

    Fair and efficient prices are a central topic in traffic policy, both at the EU level and in Switzerland. They should allow the efficient use of the infrastructure, set up fair terms of competition between road and rail traffic and reduce traffic loading. At the same time, they should also make it possible to finance traffic in a sustainable manner. One of the main directions of attack is letting those responsible pay the external costs which result from traffic jams, accidents and environmental pollution.

    Fair and efficient prices are a central topic in traffic policy, both at the European Union level and in Switzerland. They should allow the efficient use of the infrastructure, set up fair terms of competition between road and rail traffic and reduce traffic loading. At the same time, they should also make it possible to finance traffic in a sustainable manner. One of the main directions of attack is letting those responsible pay the external costs which result from traffic jams, accidents and environmental pollution. With the planned introduction of the usage-dependent heavy traffic levy, Switzerland has made an important step in the direction of true cost-allocation for goods vehicles. As for the rest of road traffic, however, considerable external costs are still not covered.

    Walking and cycling is widely assumed to substitute for at least some motorized travel and thereby reduce energy use and carbon dioxide (CO2) emissions. While the evidence suggests that a supportive built environment may be needed to promote walking and cycling, it is unclear whether and how interventions in the built environment that attract walkers and cyclists may reduce transport CO2 emissions. Our aim was therefore to evaluate the effects of providing new infrastructure for walking and cycling on CO2 emissions from motorised travel. A cohort of 1849 adults completed questionnaires at baseline (2010) and one-year follow-up (2011), before and after the construction of new high-quality routes provided as part of the Sustrans Connect2 programme in three UK municipalities. A second cohort of 1510 adults completed questionnaires at baseline and two-year follow-up (2012). The participants reported their past-week travel behaviour and car characteristics from which CO2 emissions by mode and purpose were derived using methods described previously. A set of exposure measures of proximity to and use of the new routes were derived. Overall transport CO2 emissions decreased slightly over the study period, consistent with a secular trend in the case study regions. As found previously the new infrastructure was well used at one- and two-year follow-up, and was associated with population-level increases in walking, cycling and physical activity at two-year follow-up. However, these effects did not translate into sizeable CO2 effects as neither living near the infrastructure nor using it predicted changes in CO2 emissions from motorised travel, either overall or disaggregated by journey purpose. This lack of a discernible effect on travel CO2 emissions are consistent with an interpretation that some of those living nearer the infrastructure may simply have changed where they walked or cycled, while others may have walked or cycled more but few, if any, may have substituted

    Apollo Gas, a Toronto-based gas marketer, is considering options to enhance unit holder value, including sale of its 21,000 gas supply contracts, just weeks after it was forced out of the Alberta market by rising gas prices. Although the company had reported first quarter revenues of more than $15 million and earnings through that period of about $2.1 million, increases of 33 per cent and 38 per cent respectively over the same period in 1999, the company is resigned to the fact that such performance markers are not likely to be reached again in the foreseeable future, hence the decision to sell. About 95 per cent of Apollo's current transportation service volumes are matched to existing fixed-price supply contract which are due to expire in November 2000. After that, it is about 75 per cent matched for the balance of the term of its customer contracts (mostly five years). This means that the company is exposed to market prices that are likely to continue to increase. If this prediction holds true, Apollo would be forced to purchase the unhedged volumes of gas it needs to service its customers in the spot market at prices higher than prices the company is charging to its customers.

    The lack of a hydrogen refuelling infrastructure is one of the major obstacles to the introduction of the hydrogen vehicles to the road transport market. To help overcome this hurdle a likely transitional solution is to introduce hydrogen for niche applications such as buses or other types of fleet vehicles for which fuel demand is predictable and localised. This paper analyses the costs of different hydrogen production-delivery pathways, via a case study of buses in London. Scenario analysis over time (2007-2025) is used to investigate potential changes to the cost of hydrogen as a result of technology development, growing demand for hydrogen and changes in energy prices (gas and electricity). It is found that factors related to hydrogen demand have the greatest effect on the unit cost of hydrogen, while for the whole of the analysis period, on-site SMR (steam methane reforming) remains the least-cost production-delivery pathway.

    Full text: In 2005, the Victorian Government contracted CSIRO, Maunsell Australia and Phillips Fox to undertake an overview assessment of the likely impacts of climate change on the State's infrastructure, establish the categories of infrastructure most at risk and outline opportunities for adaptation responses. The Government released the assessment in May 2007. Climate change poses a significant risk to infrastructure and its owners, managers and long-term operators. The work was undertaken on the basis that it should not be assumed that future climate and its impacts will simply be an extension of what has been experienced in the past. Major infrastructure items have long useful life spans (20-100 years). A bridge built today is expected to still be in use in tens, if not hundreds, of years. This means that recognition of likely climate change impacts and appropriate adaptation measures should occur now. Recognition of the risks associated with climate change is a valuable first step towards better planning of new infrastructure investments and reducing potential damage to existing infrastructure.lnfrastructure types examined were water, power, telecommunications, transport and buildings. The climate change projections used in this report are based on CSIRO climate modelling, supported by findings from the Intergovernmental Panel on Climate Change. Climatic and other variables considered were temperature, rainfall, available moisture, humidity, winds, fire-weather frequency and intensity, solar radiation levels and sea-level rise. For each climate change variable identified, we described a worst-case impact for low and high climate change projections for the years 2030 and 2070. The assessment was made on the basis of 'business as usual' with no adaptation responses to climate change. The report also details the current governance structures associated with each infrastructure type. Overall, the report assessed the likely impact of climate change on

    This paper evaluates the impact of fluctuating electricity prices on the cost of five options to increase the water supply to urban areas in Southern California-new surface storage, water purchases, desalination, wastewater recycling, and conservation.We show that the price of electricity required to produce and transport water influences the cost of water supply options and may alter the decision makers economic ranking of these options. When electricity prices are low, water purchase is the cost effective option. When prices exceed US$ 86/MWh, conservation of electricity and water through installation of high efficiency clothes washers is the most effective option.

    Policies to promote active transportation are emerging as a best practice to increase physical activity, yet relatively little is known about public opinion on utilizing transportation funds for such investments. This study sought to assess public awareness of and support for investments in walking and biking infrastructure in Los Angeles County. In the fall of 2013, the Los Angeles County Department of Public Health conducted a telephone survey with a random sample of registered voters in the region. The survey asked respondents to report on the presence and importance of walking and biking infrastructure in their community, travel behaviors and preferences, and demographics. One thousand and five interviews were completed (response rate 20%, cooperation rate 54%). The majority of participants reported walking, biking, and bus/rail transportation investments as being important. In addition, participants reported a high level of support for redirecting transportation funds to active transportation investment - the population average was 3.28 (between 'strongly' and 'somewhat' support) on a 4 point Likert scale. Voters see active transportation infrastructure as being very important and support redirecting funding to improve the infrastructure. These findings can inform policy-decisions and planning efforts in the jurisdiction. Copyright © 2015 Elsevier Inc. All rights reserved.

  8. Does infrastructure provision hinder energy integration? The case of natural gas in the southern cone

    Navajas, Fernando

    2010-09-15

    This paper uses evidence on policies, markets and private transactions to discuss the experience of natural gas infrastructure integration in the Southern Cone of Latin America. The argument is that contracts on international exchanges supported by infrastructure may become incomplete due to contingencies related to policy-induced price distortions not anticipated at the moment of writing. Beyond regulatory risk mitigation, it calls for back-up contract provisions designed to cope with aggregate imbalances and for some supranational coordination related to information about market conditions and on energy planning dialogues that test consistency and stress situations in markets where exports originate.

    2011-01-01

    In a quest for strategic and environmental benefits, the developed countries have been trying for many years to increase the share of alternative fuels in their transportation fuel mixes. They have met very little success though. In this paper, we examine the experience of Argentina with compressed natural gas. We conducted interviews with a wide range of stakeholders and analyzed econometrically data collected in Argentina to investigate the factors, economic, political, and others that determined the high rate of adoption of this fuel. A central objective of this research was to identify lessons that could be useful to developed countries in their efforts to deploy alternative fuel vehicles. We find that fuel price regulation was a significant determinant of the adoption of compressed natural gas, while, contrary to expectations, government financing of refueling infrastructure was minimal.

    Full Text Available This work investigates the relationship between the average export prices and the distance between the origin and the destination market in international trade. Distance between trading partners obviously stands at the core of I international trade literature and is strictly related with the issue of how countries and firms compete on export markets when transport costs become increasingly stiff. Heterogeneous-Firm Trade (HFT models predict that only most competitive firms are able to export on distant markets, where it is more difficult to recover from freight costs. However, this simple concept does not lead to unambiguous predictions on the spatial pattern of average export f.o.b. prices. \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\r\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

  12. Sustainable Urban Transport in the Developing World: Beyond Megacities

    2015-06-01

    Full Text Available Megacities have frequently received a disproportionate amount of attention over other sizes of cities in recent discourse on urban sustainability. In this article, the authors argue that a focus on smaller and medium-sized cities is crucial to achieving substantial progress towards more sustainable urban development, not only because they are home to at least a quarter of the world’s population but because they also offer great potential for sustainable transformations. In principle, their size allows for flexibility in terms of urban expansion, adoption of “green” travel modes, and environmental protection. At the same time, smaller and medium-sized cities often have fewer resources to implement new transport measures and can be more vulnerable to fluctuations in the world economy. This article critically reviews the potential role and impact of nine commonly considered options for sustainable urban transport in cities in developing countries: (1 road infrastructure; (2 rail-based public transport; (3 road-based public transport; (4 support for non-motorized travel modes; (5 technological solutions; (6 awareness-raising campaigns; (7 pricing mechanisms; (8 vehicle access restrictions; and (9 control of land-uses. Drawing on international research and examples of policies to reduce the environmental impacts of transport in urban areas, this article identifies some key lessons for sustainable urban transport in smaller and medium-sized cities in developing countries. These lessons are certainly not always identical to those for megacities in the global south.

    Full Text Available Investment decisions should not be taken without an in-depth analysis of the risks. This is an important stage in project preparation and should be performed simultaneously with the planning of the financial operations. Infrastructure development requires that project risks and responsibilities be assigned to the public or private entity that is best able to manage them. The risks and their financial impacts are usually not quantified equally by all parties. Each party views the given risks according to the guarantees provided. These guarantees are related to the form of participation in the project.

    This paper presents an optimal load management strategy for residential consumers that utilizes the communication infrastructure of the future smart grid. The strategy considers predictions of electricity prices, energy demand, renewable power production, and power-purchase of energy of the consumer in determining the optimal relationship between hourly electricity prices and the use of different household appliances and electric vehicles in a typical smart house. The proposed strategy is illustrated using two study cases corresponding to a house located in Zaragoza (Spain) for a typical day in summer. Results show that the proposed model allows users to control their diary energy consumption and adapt their electricity bills to their actual economical situation. - Highlights: ► This work shows an optimal load management strategy for residential consumers. ► It has been considered the communication infrastructure of the future smart grid. ► A study case shows the optimal utilization of some appliances and electric vehicles. ► Results showed that the proposed model allows users to reduce their electricity bill.

  17. Analysis of extreme values of the economic efficiency indicators of transport infrastructure projects

    2017-10-01

    Paper builds on previous research of the authors into the evaluation of economic efficiency of transport infrastructure projects evaluated by the economic efficiency ratio - NPV, IRR and BCR. Values of indicators and subsequent outputs of the sensitivity analysis show extremely favourable values in some cases. The authors dealt with the analysis of these indicators down to the level of the input variables and examined which inputs have a larger share of these extreme values. NCF for the calculation of above mentioned ratios is created by benefits that arise as the difference between zero and investment options of the project (savings in travel and operating costs, savings in travel time costs, reduction in accident costs and savings in exogenous costs) as well as total agency costs. Savings in travel time costs which contribute to the overall utility of projects by more than 70% appear to be the most important benefits in the long term horizon. This is the reason why this benefit emphasized. The outcome of the article has resulted how the particular basic variables contributed to the total robustness of economic efficiency of these project.

  18. Deregulation, market structure and gas prices in the Canadian Natural Gas Industry

    International Nuclear Information System (INIS)

    Uhler, R.S.

    1992-01-01

    During the course of the development of the natural gas industry in Canada, gas purchase and sales markets have evolved from being relatively free of regulation to being highly regulated and back again. Though pipeline transport charges were regulated, the pipeline companies, or their subsidiaries, owned the gas that they transported and price and other provisions of purchase and sales contracts were freely negotiated with the producers at one end and distributing utilities or industrial users at the other end. The Western Accord of 1985 set the process of deregulation of the Canadian natural gas industry in motion. On November 1, 1986, natural gas prices in interprovincial trade were deregulated in that domestic natural gas prices were to be freely negotiated. Although not stated explicitly, government policy is to permit export prices to be freely negotiated so long as they do not fall below domestic prices. The deregulation process has dramatically changed the relationship between buyers and sellers. Of particular importance is that deregulation has permitted companies to negotiate gas purchase contracts directly with producers with the pipeline company acting solely as a gas transporter. The purpose of this paper is to examine the forces that have led to shorter term contracts and to examine the likely effect of these contract terms on reservoir development investment incentives. 5 refs., 3 figs

  20. Demystifying the Barriers to Transport Infrastructure Project Development in Fast Developing Regions: The Case of China

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available Transport infrastructure (TI has become one of the primary drivers for sustainable economic growth and social progress. However, a wider take-up is currently inhibited in fast developing regions (FDRs by many barriers, which have not been explored explicitly in previous studies. In this study, a three-dimensional framework (i.e., macro environment, local environment, and the construction process is proposed to structure the barriers in a reasonable way. Professionals’ opinions on the importance of the barriers are collected through questionnaire survey. The survey results were analyzed by the ranking analysis technique. It is found that the top five barriers are “difficulty in survey and design during the construction process”, “weak support from economy”, “insufficient funding”, “harsh regional climate”, and “cost overrun”. Further analysis, based on a factor analysis, indicates that these critical barriers could be grouped into three clusters: “administration on transport infrastructure”, “construction technology and cost management”, and “geographical and economic conditions”. The research findings demonstrate the usefulness of the proposed framework, and the implication is that a barriers-based checklist favors stakeholders to improve the efficiency and sustainability of TI development in FDRs. Although the study is situated in China, it sheds light on the subject in other developing countries.

  2. Regional prices in the Swedish wood-fuel market

    International Nuclear Information System (INIS)

    Hillring, Bengt

    1999-01-01

    This paper analyses, through a statistical survey, the regional distribution of prices on the commercial wood-fuel market for district heating plants and the pellets market for single family houses. The existing market watch of the national Swedish wood-fuel market has been developed for both refined and unrefined wood-fuels. The last five years the trend for wood-fuel prices on the district heating market has been stable, with a slight increase in the price of refined wood-fuels. However, on the young and fast-growing household market for pellets, prices have increased 12% during the last three years. The distribution of prices for northern, middle and southern Sweden indicates differences within 5% between the regions. The limited price difference between Swedish regions are a product of a large domestic supply and an increasing trade among regions in Europe, putting pressure on prices. Regional differences, mirrored as transportation distances and local production costs are key factors that could explain this regional price variation. However, the development of a commercial market with less regulation tends to level out prices. Consumers on the household market purchase small quantities and do not have the same possibility as district heating companies to take advantage of the oversupply opportunity and thus face a faster price development. The weaker market position of the consumers also tends to give homogeneous prices between regions of the residential sector. (Author)

    The outlook for Canadian natural gas in Western U.S. markets through the winter of 1997 and 1998 was discussed. The effect of El Nino on West Coast gas pricing was noted, while also admitting that the best scientific minds are unable to determine what these effects actually are. Both the Cambridge Energy Research Associates (CERA) and PIRA predicted that Topock (the border pricing point) prices will track the NYMEX Henry Hub prices. The three points that were emphasized for the winter of 1997-1998 were: (1) Western U.S. pricing is higher than last year, (2) there is a surplus of gas in Canada relative to export capacity, and (3) differentials are anticipated to remain in excess of full transportation costs. The 1997 gas accord rates were also noted and its significance discussed. Increased electric load growth is likely to result in higher electricity prices which may drag gas prices along with them. Any new power generation facility is likely to be gas-fired, a fact which should also help to maintain natural gas prices. Transmission pricing is the major unknown variable. It is well known that from a capital cost perspective it is about four times more expensive to build a high -Kv transmission line than to build a gas pipeline to deliver the equivalent amount of energy. Therefore, to the degree that transmission pricing favours building new generation near load centres, gas should do well. If on the other hand, transmission pricing favours building generation plants near the fuel source, gas probably would not do nearly as well. The effects will not be known until the relevant decisions have been made. 6 figs

    A new concept study was initiated to examine the architecture needed to gradually develop an economical, evolvable and sustainable lunar infrastructure using a public/private partnerships approach. This approach would establish partnership agreements between NASA and industry teams to develop a lunar infrastructure system that would be mutually beneficial. This approach would also require NASA and its industry partners to share costs in the development phase and then transfer operation of these infrastructure services back to its industry owners in the execution phase. These infrastructure services may include but are not limited to the following: lunar cargo transportation, power stations, communication towers and satellites, autonomous rover operations, landing pads and resource extraction operations. The public/private partnerships approach used in this study leveraged best practices from NASA's Commercial Orbital Transportation Services (COTS) program which introduced an innovative and economical approach for partnering with industry to develop commercial cargo services to the International Space Station. This program was planned together with the ISS Commercial Resupply Services (CRS) contracts which was responsible for initiating commercial cargo delivery services to the ISS for the first time. The public/private partnerships approach undertaken in the COTS program proved to be very successful in dramatically reducing development costs for these ISS cargo delivery services as well as substantially reducing operational costs. To continue on this successful path towards installing economical infrastructure services for LEO and beyond, this new study, named Lunar COTS (Commercial Operations and Transport Services), was conducted to examine extending the NASA COTS model to cis-lunar space and the lunar surface. The goals of the Lunar COTS concept are to: 1) develop and demonstrate affordable and commercial cis-lunar and surface capabilities, such as lunar cargo

    Consumer preferences are key to the adoption of new vehicle technologies. Barriers to consumer adoption include price and other obstacles, such as limited driving range and charging infrastructure; unfamiliarity with the technology and uncertainty about direct benefits; limited makes and models with the technology; reputation or perception of the technology; standardization issues; and regulations. For each of these non-cost barriers, this report estimates an effective cost and summarizes underlying influences on consumer preferences, approximate magnitude and relative severity, and assesses potential actions, based on a comprehensive literature review. While the report concludes that non-cost barriers are significant, effective cost and potential market share are very uncertain. Policies and programs including opportunities for drivers to test drive advanced vehicles, general public outreach and information programs, incentives for providing charging and fueling infrastructure, and development of technology standards were examined for their ability to address barriers, but little quantitative data exists on the effectiveness of these measures. This is one in a series of reports produced as a result of the Transportation Energy Futures project, a Department of Energy-sponsored multi-agency effort to pinpoint underexplored strategies for reducing GHGs and petroleum dependence related to transportation.

    Highlights: • CHP and biomethane generation were investigated as biogas utilization pathways. • A spatially explicit biogas supply chain optimization model was developed. • Biomethane as vehicle fuel has lower investment and operational costs than CHP. • CHP has most favorable economics thanks to high carbon reduction potential. - Abstract: Italy is a large producer of biogas from anaerobic digestion, which is mainly used for power generation with limited use of cogenerated heat. Other utilization pathways, such as biomethane injection into the natural gas grid or biomethane used as a vehicle fuel, remain unexplored. Given the dense grid of natural gas pipelines and existing Compressed Natural Gas (CNG) refueling stations in northern Italy, significant market opportunities for biogas could also arise in the heating and transport sectors. The main objectives of this paper are to explore the potential role of agricultural biogas in different utilization pathways. Biogas combustion for simultaneous production of heat and power in small Combined Heat and Power (CHP) facilities is also assessed, as is upgrading to biomethane for transport or natural gas grid injection in the specific context of northern Italy. The spatially explicit optimization model BeWhere is used to identify optimal locations where greenfield biogas plants could be installed and to determine the most economic and environmentally beneficial mix of conversion technologies and plant capacities. Carbon price, for instance in the form of tradable emission permits, is assessed as a policy instrument and compared with other options such as price premiums on biomethane or electricity costs. Results show that starting from a carbon price of 15 EUR/tCO_2, the cogeneration option is preferable if plants are located in the proximity of existing district heating infrastructure. CNG plants are only competitive starting at a carbon price of 70 EUR/tCO_2 in areas with high feedstock availability. The

    This article assess the magnitudes of costs to replace oil (and natural gas) in their fixed (heat) or mobile (transport) uses with energy savings or non CO 2 emitting energies. The price of oil (or gas) at which such measures would be profitable at is inferred, without any tax or subsidy, as well as the resulting CO 2 costs avoided. It shows that several of the actions considered in France and Europe to protect the climate are far from being the most economically justified. (author)

  14. The price of oil and the future of Middle East Gas

    1997-01-01

    Most LNG contracts relate the LNG price received by the supplier at the point of delivery to a relevant oil price. Gas and oil are thus closely connected so that when the price of landed oil decreases so dose the price of delivered LNG. With large fixed transportation and liquefaction costs, accounting for around 85% of the supply cost of delivered LNG in the case of Qatari LNG supplied to japan, you can imagine how large falls in the price paid for delivered LNG would squeeze the net back to the producer back in Qatar. However, low oil price can do some damage to the economics of existing LNG projects in the Middle East. More importantly, persistently low oil prices can prevent new LNG projects from leaving the drawing board-which will stifle the exciting export potential of Middle Eastern gas

    This paper presents a search algorithm based framework to calibrate origin-destination (O-D) market specific airline ticket demands and prices for the Air Transportation System (ATS). This framework is used for calibrating an agent based model of the air ticket buy-sell process - Airline Evolutionary Simulation (Airline EVOS) -that has fidelity of detail that accounts for airline and consumer behaviors and the interdependencies they share between themselves and the NAS. More specificially, this algorithm simultaneous calibrates demand and airfares for each O-D market, to within specified threshold of a pre-specified target value. The proposed algorithm is illustrated with market data targets provided by the Transportation System Analysis Model (TSAM) and Airline Origin and Destination Survey (DB1B). Although we specify these models and datasources for this calibration exercise, the methods described in this paper are applicable to calibrating any low-level model of the ATS to some other demand forecast model-based data. We argue that using a calibration algorithm such as the one we present here to synchronize ATS models with specialized forecast demand models, is a powerful tool for establishing credible baseline conditions in experiments analyzing the effects of proposed policy changes to the ATS.

  16. Transport and agricultural productivity: A cross-national analysis

    Full Text Available The transportation infrastructure plays a significant role in the development of agriculture. In this study we examine the relationship between transport and agricultural performance by employing the World Bank’s roads infrastructure indicators. Based on a cross-country sample, a classic method is employed to test the hypothesis that better transport fosters agricultural productivity. The empirical results of the method support the hypothesis. As for this method, the estimation results of the widely-used inter-country aggregate agricultural production function describe that a country with better transport can produce more agricultural outputs given the same amounts of agricultural inputs and the same education level. Our empirical work lends support to the claim of Gollin and Rogerson (2010 [19] that transport is a basic factor explaining the poor economic performance of many developing countries, apart from physical and education investments, more emphasis should be placed on improving the transport infrastructure of these countries.

  17. Spatial and intertemporal arbitrage in the California natural gas transportation and storage network

    Science.gov (United States)

    Uria Martinez, Rocio

    Intertemporal and spatial price differentials should provide the necessary signals to allocate a commodity efficiently inside a network. This dissertation investigates the extent to which decisions in the California natural gas transportation and storage system are taken with an eye on arbitrage opportunities. Daily data about flows into and out of storage facilities in California over 2002-2006 and daily spreads on the NYMEX futures market are used to investigate whether the injection profile is consistent with the "supply-of-storage" curve first observed by Working for wheat. Spatial price differentials between California and producing regions fluctuate throughout the year, even though spot prices at trading hubs across North America are highly correlated. In an analysis of "residual supply", gas volumes directed to California are examined for the influence of those fluctuations in locational differentials. Daily storage decisions in California do seem to be influenced by a daily price signal that combines the intertemporal spread and the locational basis between California and the Henry Hub, in addition to strong seasonal and weekly cycles. The timing and magnitude of the response differs across storage facilities depending on the regulatory requirements they face and the type of customers they serve. In contrast, deviations in spatial price differentials from the levels dictated by relative seasonality in California versus competing regions do not trigger significant reallocations of flows into California. Available data for estimation of both the supply-of-storage and residual-supply curves aggregate the behavior of many individuals whose motivations and attentiveness to prices vary. The resulting inventory and flow profiles differ from those that a social planner would choose to minimize operating costs throughout the network. Such optimal allocation is deduced from a quadratic programming model, calibrated to 2004-2005, that acknowledges relative seasonality

    Economic factors such as rising gasoline prices may contribute to the crash trends by shaping individuals' choices of transportation modalities. This study examines the relationship of gasoline prices with fatal and non-fatal motorcycle injuries. Data on fatal and non-fatal motorcycle injuries come from California's Statewide Integrated Traffic Records System for 2002-2011. Autoregressive integrated moving average (ARIMA) regressions were used to estimate the impact of inflation-adjusted gasoline price per gallon on trends of motorcycle injuries. Motorcycle fatalities and severe and minor injuries in California were highly correlated with increasing gasoline prices from 2002 to 2011 (r=0.76, 0.88 and 0.85, respectively). In 2008, the number of fatalities and injuries reached 13,457--a 34% increase since 2002, a time period in which inflation-adjusted gasoline prices increased about $0.30 per gallon every year. The majority of motorcycle riders involved in crashes were male (92.5%), middle-aged (46.2%) and non-Hispanic white (67.9%). Using ARIMA modelling, we estimated that rising gasoline prices resulted in an additional 800 fatalities and 10,290 injuries from 2002 to 2011 in California. Our findings suggest that increasing gasoline prices led to more motorcycle riders on the roads and, consequently, more injuries. Aside from mandatory helmet laws and their enforcement, other strategies may include raising risk awareness of motorcyclists and investment in public transportation as an alternative transportation modality to motorcycling. In addition, universally mandated training courses and strict licensing tests of riding skills should be emphasised to help reduce the motorcycle fatal and non-fatal injuries.

  19. Optimal Operation of Interdependent Power Systems and Electrified Transportation Networks

    Directory of Open Access Journals (Sweden)

    M. Hadi Amini

    2018-01-01

    Full Text Available Electrified transportation and power systems are mutually coupled networks. In this paper, a novel framework is developed for interdependent power and transportation networks. Our approach constitutes solving an iterative least cost vehicle routing process, which utilizes the communication of electrified vehicles (EVs with competing charging stations, to exchange data such as electricity price, energy demand, and time of arrival. The EV routing problem is solved to minimize the total cost of travel using the Dijkstra algorithm with the input from EVs battery management system, electricity price from charging stations, powertrain component efficiencies and transportation network traffic conditions. Through the bidirectional communication of EVs with competing charging stations, EVs’ charging demand estimation is done much more accurately. Then the optimal power flow problem is solved for the power system, to find the locational marginal price at load buses where charging stations are connected. Finally, the electricity prices were communicated from the charging stations to the EVs, and the loop is closed. Locational electricity price acts as the shared parameter between the two optimization problems, i.e., optimal power flow and optimal routing problem. Electricity price depends on the power demand, which is affected by the charging of EVs. On the other hand, location of EV charging stations and their different pricing strategies might affect the routing decisions of the EVs. Our novel approach that combines the electrified transportation with power system operation, holds tremendous potential for solving electrified transportation issues and reducing energy costs. The effectiveness of the proposed approach is demonstrated using Shanghai transportation network and IEEE 9-bus test system. The results verify the cost-savings for both power system and transportation networks.

  20. Decision analysis and risk models for land development affecting infrastructure systems.

    Coordination and layering of models to identify risks in complex systems such as large-scale infrastructure of energy, water, and transportation is of current interest across application domains. Such infrastructures are increasingly vulnerable to adjacent commercial and residential land development. Land development can compromise the performance of essential infrastructure systems and increase the costs of maintaining or increasing performance. A risk-informed approach to this topic would be useful to avoid surprise, regret, and the need for costly remedies. This article develops a layering and coordination of models for risk management of land development affecting infrastructure systems. The layers are: system identification, expert elicitation, predictive modeling, comparison of investment alternatives, and implications of current decisions for future options. The modeling layers share a focus on observable factors that most contribute to volatility of land development and land use. The relevant data and expert evidence include current and forecasted growth in population and employment, conservation and preservation rules, land topography and geometries, real estate assessments, market and economic conditions, and other factors. The approach integrates to a decision framework of strategic considerations based on assessing risk, cost, and opportunity in order to prioritize needs and potential remedies that mitigate impacts of land development to the infrastructure systems. The approach is demonstrated for a 5,700-mile multimodal transportation system adjacent to 60,000 tracts of potential land development. © 2011 Society for Risk Analysis.
