Road transport of LWR spent fuel in the Federal Republic of Germany

International Nuclear Information System (INIS)

Bach, R.

1987-01-01

Since 1967, when fuel from LWRs was first transported by road from the Kahl reactor in the Federal Republic of Germany to the Eurochemic reprocessing plant in Belgium, a total of more than 400 road transports have been performed without any adverse effect on the environment. In the beginning, road transport was the dominant mode. However, in recent years large capacity rail flasks with a weight ranging from 80 to 110 tonnes have been put into service in order to cope with the increasing demand of transport services and to replace existing smaller flasks designed primarily for road transport. Therefore, the number of spent fuel transports by road has declined. However, road transport of heavy flasks from reactor sites without a direct rail link to a nearby rail terminal has become an important task and a number of special problems have had to be solved. The following items are discussed, with special emphasis placed on heavy load transports by road from the reactor to a nearby rail terminal: design of road transport equipment to meet the requirements of the national traffic law; application of technical and administrative procedures to meet the IAEA Regulations; transport restrictions due to overload/oversize; transfer of the flask from the reactor to the transport vehicle; handling of the flask at the rail terminal; turn-around inspection and periodic maintenance of equipment to ensure safe performance of transport; and physical protection during transport and handling at rail terminals.

Mraihi, Rafaa; Abdallah, Khaled ben; Abid, Mehdi

2013-01-01

The rapid growth of urban population and the development of road infrastructures in Tunisian cities have brought about many environmental and economic problems, including the rise scored in energy consumption and the increase in the quantity of gas emissions arising from road transport. Despite the critical nature of such problems, no policies have yet been adopted to improve energy efficiency in the transport sector. This paper aims to determine driving factors of energy consumption change for the road mode. It uses decomposition analysis to discuss the effects of economic, demographic and urban factors on the evolution of transport energy consumption. The main result highlighted in the present work is that vehicle fuel intensity, vehicle intensity, GDP per capita, urbanized kilometers and national road network are found to be the main drivers of energy consumption change in the road transport sector during 1990–2006 period. Consequently, several strategies can be elaborated to reduce road transport energy. Economic, fiscal and regulatory instruments can be applied in order to make road transport more sustainable. -- Highlights: •We are interested in determining driving factors of transport energy consumption growth in Tunisia. •We use decomposition analysis approach. •Vehicle fuel and road vehicle intensities are found to be principal factors. •Motorization and urbanization are also found to be responsible

On Transport Service Selection in Intermodal Rail/Road Distribution Networks

Directory of Open Access Journals (Sweden)

Christian Bierwirth

2012-11-01

Full Text Available Intermodal rail/road freight transport constitutes an alternative to long-haul road transport for the distribution of large volumes of goods. The paper introduces the intermodal transportation problem for the tactical planning of mode and service selection. In rail mode, shippers either book train capacity on a per-unit basis or charter block trains completely. Road mode is used for short-distance haulage to intermodal terminals and for direct shipments to customers. We analyze the competition of road and intermodal transportation with regard to freight consolidation and service cost on a model basis. The approach is applied to a distribution system of an industrial company serving customers in eastern Europe. The case study investigates the impact of transport cost and consolidation on the optimal modal split.

Ben Abdallah, Khaled; Belloumi, Mounir; De Wolf, Daniel

2015-01-01

The present work provides an international comparison of the energy intensity and the carbon dioxide intensity in road transport for a group of 90 countries over the period 1980–2012. This paper attempts to perform a comparative analysis to find the most appropriate mapping of the energy performance in road transport taking into account the three dimensions of sustainable energy development, namely road transport-related energy consumption, economic growth and carbon dioxide emissions. An important result of the study is the inverse relationship between energy efficiency and environmental efficiency. Through the calculated Theil coefficient, our empirical findings highlight the existence of spatial and temporal disparities between countries. In 2012, Tunisia occupies the 48th and the 38th rank respectively in terms of energy and environmental efficiency. Based on a general index of energy performance in the road transport sector, it is deemed to have a medium–high energy performance by occupying the 34th rank. The study shows the importance of enhancing a number of policies for the road transport system through the joint improvement of the fuel price policy, of the road infrastructure policy and of the fuel-efficient road vehicles policy, in order to maintain sustainable energy road transport. - Highlights: • The paper presents an international comparative analysis of the energy performance. • The road transport is analyzed for a group of 90 countries over the period 1980–2012. • There is no convergence between energy and environmental efficiencies. • Tunisia has a medium-high energy performance by occupying the 34th rank in 2012. • The findings show the importance of enhancing some policies for the road transport.

Risk management model in road transport systems

Sakhapov, R. L.; Nikolaeva, R. V.; Gatiyatullin, M. H.; Makhmutov, M. M.

2016-08-01

The article presents the results of a study of road safety indicators that influence the development and operation of the transport system. Road safety is considered as a continuous process of risk management. Authors constructed a model that relates the social risks of a major road safety indicator - the level of motorization. The model gives a fairly accurate assessment of the level of social risk for any given level of motorization. Authors calculated the dependence of the level of socio-economic costs of accidents and injured people in them. The applicability of the concept of socio-economic damage is caused by the presence of a linear relationship between the natural and economic indicators damage from accidents. The optimization of social risk is reduced to finding the extremum of the objective function that characterizes the economic effect of the implementation of measures to improve safety. The calculations make it possible to maximize the net present value, depending on the costs of improving road safety, taking into account socio-economic damage caused by accidents. The proposed econometric models make it possible to quantify the efficiency of the transportation system, allow to simulate the change in road safety indicators.

Laboratory tests have given good experiences to develop the technology of building transport roads for truck on peat bogs. The experiences can be summarized in the following points: The bearing capacity can be increased 15-20 times by mixing down, to the depth of 0,5 m, a mixture of gypsum and T-lime. high bearing surface capacity has been achieved at laboratory tests by mixing sulfonated lignin/sodiumbichromate or cement into peat. These mixtures can take a load of 610 kPa will be tested in the field. An ordinary base machine can be used with some modifications for the new technique. Costs for building roads and stores with the new technique can save 6 MSEK/year in Sweden. Remainig problems at full scale tests are: Testroads should be built to get knowledge of settlement, bearing capacity cost of maintenance etc. Heavy metals pollution. Machinery for transportation and admixture of the stabilizing agents must be deloped. By experience a good mixture between firm soil and peat is difficult to achieve. Technique and dimensioning to make a soft mixture ought to be studied.

Full Text Available Analysis of road traffic accidents revealed that most accidents are as a result of drivers’ errors. Over the years, active safety systems (ASS were devised in vehicle to reduce the high level of road accidents, caused by human errors, leading to death and injuries.This study however evaluated the impacts of ASS inclusions into vehicles in Nigeria road transportation network. The objectives was to measure how ASS contributed to making driving safer and enhanced transport safety. Road accident data were collected, for a period of eleven years, from Lagos State Ministry of Economic Planning and Budget, Central Office of Statistics. Quantitative analysis of the retrospective accident was conducted by computing the proportion of yearly number of vehicles involved in road accident to the total number of vehicles for each year. Results of the analysis showed that the proportion of vehicles involved in road accidents decreased from 16 in 1996 to 0.89 in 2006, the injured persons reduced from 15.58 in 1998 to 0.3 in 2006 and the death rate diminished from 4.45 in 1998 to 0.1 in 2006. These represented 94.4%, 95% and 95% improvement respectively on road traffic safety. It can therefore be concluded that the inclusions of ASS into design of modern vehicles had improved road safety in Nigeria automotive industry.

Following the agreement between French and German professionals of automobile and industrial vehicle, the Road Transport world exhibition will take place alternatively in Paris and Hanover. The 1995 meeting has taken place in Paris (September 15-21) and about 20 countries were represented. Road transport is the principal way of goods transportation in France and represent 88% of the traffic explained in tons gross and 70% in tons km. The petroleum dependence of the transportation sector is becoming a worrying problem as the gasoline and diesel fuels taxes will be discussed in the 1996 financial laws project. According to the last ''Worldwide energetic perspectives'' report published by the IEA, in 2010 the transportation sector could absorb more than 60% of the worldwide petroleum consumption. This increase represents a challenge to the petroleum industry to increase the energetic efficiency of the vehicle fuels and the production of diesel fuels, and conversely to reduce the pollution effluents.

Full Text Available Surveying the recent trend toward e-commerce and computerization in the trucking industry, this paper establishes a framework for analyzing the impact of information and communication technology on road freight transportation in terms of commerce, logistics and fleet management, and proposes hypothetical mechanisms of influence. The authors note that the rapid growth of e-commerce and freight fleet management systems make it difficult to arrive at firm, statistics-based conclusions about their impact on road freight transportation, but suggest that more sophisticated government management of transportation demand as well as freight fleet management systems could cancel out the negative impact of e-commerce on road transportation.

THE PLANNING OF WOOD TRANSPORT ON THE FOREST ROADS

2001-04-01

Full Text Available Nowadays, needs for forest and raw wood materials has been increasing with the economic developments of the societies. But, the forest areas have been decreasing because of the pressures of the societies on forest especially in developing countries. In such regions, forest areas were on high mountainous areas. This situation is the same in Turkey, especially east Black Sea region. In Turkey, forest roads are still B forms of secondary roads. The wide of these roads are minimum 4 meters, generally minimum curve radius of them are 10 meters, and some times less then that. These roads do not have pavement and maintenance works were not made there too. And these roads are not suitable for transportation with truck-trailer. The transhipment problems form a typical example of the linear programming method. When this method applied, as well as solving transportation problems, distribution problems are solved related to transhipment.

2018-04-01

Connected and Autonomous Vehicles (CAV) are set to revolutionise the way in which we use our transportation system. However, we do not fully understand how the integration of wireless and autonomous technology into the road transportation network affects overall network dynamism. This paper uses the theoretical principles underlying Distributed Cognition to explore the dependencies and interdependencies that exist between system agents located within the road environment, traffic management centres and other external agencies in both non-connected and connected transportation systems. This represents a significant step forward in modelling complex sociotechnical systems as it shows that the principles underlying Distributed Cognition can be applied to macro-level systems using the visual representations afforded by the Event Analysis of Systemic Teamwork (EAST) method.

This is a private members Bill which will enable new rules to be set out that will govern the way in the which nearly 500,000 shipments of radioactive and nuclear material go by road in the United Kingdom every year. It would give the Department of Transport, which would become the enforcing authority, the powers of entry and inspection and allows penalties to be exacted from those breaking the rules. The present regulations for transport by road are those set out in 1947 and these need to be updated to comply with International Atomic Energy Authority Standards. The debate which lasted over one and a half hours is reported verbatim. The main points raised were about which emergency services if any should be notified on the transport of nuclear materials, with particular reference to Derbyshire. Nuclear power in general was also discussed. (UK)

A proposed regulatory framework for road and rail freight transport in South Africa

Directory of Open Access Journals (Sweden)

Wessel Pienaar

2007-09-01

Full Text Available The increase in the number of freight vehicles on South Africa’s rural road network has received substantial attention. Insinuations persist that long-distance road freight haulage is of a somewhat unsavoury economic nature, and that strict economic re-regulation of the land freight transport is necessary. During the 1970s road transport replaced rail carriage as the dominant form of long-distance freight transport (excluding minerals and ore in South Africa. On long hauls road freight carriers transport certain primary products of an organic nature (such as timber, fish and agricultural produce, some semi-finished goods, many finished goods and most consumer goods. Road freight carriers are continuously gaining market share on long-distance links where rail transport is the more cost efficient mode. The greater value added by road freight carriers in comparison with rail transport through service effectiveness is often more than the cost premium paid for utilising their service rather than making use of rail transport. Throughout history, governments have involved themselves in transport. A diverse range of arguments have been advanced for this involvement in transport, including the following:Control of excessive competition, co-ordination of transport, integration of transport with economic policy, maintenance of safety, security, and order, provision of costly infrastructure, provision of public goods, recovery of the true resource cost of transport inputs, regulation of harmful conduct and externalities, restraint of monopoly power, and social support. A set of nine instruments can be identified that governments apply to influence the performance of the freight transport industry: Legislation, direct supply, fiscal measures, monetary measures, moral appeal and persuasion, policies relating to strategic commodities, procurement policy, provision of information, and research and development. The best prospects for a sound development of

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

Future of energy efficiency and carbon dioxide emissions of Finnish road freight transport

Energy Technology Data Exchange (ETDEWEB)

Liimatainen, H.

2013-05-15

The targets to reduce the carbon dioxide emissions to mitigate climate change are as much applicable to the road freight transport sector as they are to all other sectors of society. The aim of this research is to support the initiatives of the Finnish government for improving the energy efficiency and reducing the CO{sub 2} emissions of road freight transport. This is done by forecasting the future development and giving the policy makers guidance on effective measures for promoting road freight energy efficiency and CO{sub 2} reduction. In the study a new method was introduced for connecting the fuel consumption data and goods transport data gathered from the official Finnish road statistics. This method enabled a detailed analysis of the interrelations between the economy, road freight transport, energy consumption and emissions. This analysis was conducted for the years 1995-2010 and the results were used as background information in the Delphi panel of experts. The experts estimated the development of the Finnish road freight sector to the year 2030. Furthermore, a web-based survey was conducted among Finnish road freight hauliers and shippers in order to explore the attitudes and measures related to the energy efficiency. Expert panel workshops were also organised to identify obstacles for the development of the energy efficiency of road freight transport as well as a wide selection of measures to overcome them. The results indicate that the economic development of different branches has a great effect on the energy efficiency and carbon dioxide emissions of road freight transport. Reaching the carbon emission target for the year 2030 is possible in the light of the scenarios which were formed based on expert forecasts. However, the target can be achieved with very different development paths, e.g. the structure of the national economy and the volume of transport seem to vary widely in the different scenarios. In the proposed recommendations on the measures

SPECIFIC FEATURES OF HIGHER EFFICIENCY IN FUNCTIONING OF ROAD-TRANSPORT COMPLEX IN THE REPUBLIC OF BELARUS

Directory of Open Access Journals (Sweden)

M. G. Solodkaya

2015-01-01

Full Text Available The road-transport complex objectively reflects the essence of efficient transportation process which is carried out by transport facilities along the highways. The complex  emphasizes an equivalent contribution of transport facilities and highways in a unified transportation process. Efficiency of the state economy rigidly depends on availability of the developed and well-functioning network of highways. Countries with the developed economy which have generally finished creation of national highway networks continue to invest money in public road systems that stimulates development of industrial sectors, agriculture and trade, etc. Their progress and efficient functioning is possible only with the balanced, overall development of the road-transport complex of the country. Functioning of the road-transport complex is inextricable connected with the operation of automotive transport and road infrastructure. Interaction of these two components of the unified economic system is determined by technical characteristics of the automotive transport and transport and operational indices of  the highways. Development of methods for optimum organization of management for functioning of the road complex is considered as an important problem of the national economy while forming market economy mechanisms. Further growth of capital expenditures including  investments will be needed in order to ensure such road conditions that meet the requirements of modern and perspective road traffic. Management of the highway network conditions presupposes a selection of such set of regulatory impacts on road conditions which will allow to minimize expenses in the road-transport complex. Elaboration and realization of the most efficient repair measures serve as such regulatory impact. The purpose is achieved while solving the problem pertaining to minimization of expenses on  transportations in the road-transport complex in the process of the realization of the most

Li, Hongqi; Lu, Yue; Zhang, Jun; Wang, Tianyi

2013-01-01

We adopted the simple average Divisia index approach to explore the impacts of factors on the carbon dioxide (CO 2 ) emissions from road freight transportation in China from 1985 to 2007. CO 2 emissions were investigated using the following as influencing factors: the emission coefficient, vehicle fuel intensity, working vehicle stock per freight transport operator, market concentration level, freight transportation distance, market share of road freight transportation, ton-kilometer per value added of industry, industrialization level and economic growth. Building on the results, we suggest that economic growth is the most important factor in increasing CO 2 emissions, whereas the ton-kilometer per value added of industry and the market concentration level contribute significantly to decreasing CO 2 emissions. We also discussed some recent important policies concerning factors contained in the decomposition model. - Highlights: ► We estimated road freight fuel consumption and CO 2 emissions in China. ► Factors implying features of road freight were considered in decomposition model. ► Some policies were discussed to affect CO 2 emissions from road freight

Estimation on oil demand and oil saving potential of China's road transport sector

International Nuclear Information System (INIS)

Lin, Boqiang; Xie, Chunping

2013-01-01

China is currently in the stage of industrialization and urbanization, which is characterized by rigid energy demand and rapid growth of energy consumption. Therefore, energy conservation will become a major strategy for China in a transition to low-carbon economy. China's transport industry is of high energy consumption. In 2010, oil consumption in transport industry takes up 38.2% of the country's total oil demand, of which 23.6% is taken up by road transport sector. As a result, oil saving in China's road transport sector is vital to the whole nation. The co-integration method is developed to find a long-run relationship between oil consumption and affecting factors such as GDP, road condition, labor productivity and oil price, to estimate oil demand and to predict future oil saving potential in China's transport sector under different oil-saving scenarios. Monte Carlo simulation is further used for risk analysis. Results show that under BAU condition, oil demand of China's road transport sector will reach 278.5 million ton of oil equivalents (MTOE) in 2020. Oil saving potential will be 86 MTOE and 131 MTOE under moderate oil-saving scenario and advanced oil-saving scenario, respectively. This paper provides a reference to establishing oil saving policy for China's road transport sector. - Highlights: • We adopt the co-integration model to estimate oil demand and oil saving potential of China's road transport sector. • Monte Carlo simulation is further used for risk analysis. • GDP, ratio of classified highway, labor productivity and oil price are main factors affecting oil consumption. • Scenario analysis approach is applied to calculate oil saving potential under different energy saving scenarios. • Future policy for oil conservation in China's road transport sector is suggested

An Agent-Based Model for Optimization of Road Width and Public Transport Frequency

Directory of Open Access Journals (Sweden)

Mark E. Koryagin

2015-04-01

Full Text Available An urban passenger transportation problem is studied. Municipal authorities and passengers are regarded as participants in the passenger transportation system. The municipal authorities have to optimise road width and public transport frequency. The road consists of a dedicated bus lane and lanes for passenger cars. The car travel time depends on the number of road lanes and passengers’ choice of travel mode. The passengers’ goal is to minimize total travel costs, including time value. The passengers try to find the optimal ratio between public transport and cars. The conflict between municipal authorities and the passengers is described as a game theoretic model. The existence of Nash equilibrium in the model is proved. The numerical example shows the influence of the value of time and intensity of passenger flow on the equilibrium road width and public transport frequency.

Full Text Available Road freight transportation between provinces of a country has an important effect on the traffic flow of intercity transportation networks. Therefore, an accurate estimation of the road freight transportation for provinces of a country is so crucial to improve the rural traffic operation in a large scale management. Accordingly, the focused case study database in this research is the information related to Iran’s provinces in the year 2008. Correlation between road freight transportation with variables such as transport cost and distance, population, average household income and Gross Domestic Product (GDP of each province is calculated. Results clarify that the population is the most effective factor in the prediction of provinces’ transported freight. Linear Regression Model (LRM is calibrated based on the population variable, and afterwards Fuzzy Regression Algorithm (FRA is generated on the basis of the LRM. The proposed FRA is an intelligent modified algorithm with an accurate prediction and fitting ability. This methodology can be significantly useful in macro-level planning problems where decreasing prediction error values is one of the most important concerns for decision makers. In addition, Back-Propagation Neural Network (BPNN is developed to evaluate the prediction capability of the models and to be compared with FRA. According to the final results, the modified FRA estimates road freight transportation values more accurately than the BPNN and LRM. Finally, in order to predict the road freight transportation values, the reliability of the calibrated models is analyzed using the information of the year 2009. Results show higher reliability for the proposed modified FRA.

China is the world's second largest greenhouse gas emitter, and emissions from the road transport sector represent one of the fastest growing GHG sources in China. Taking previous research on China's projected future vehicle ownership and future CO 2 emissions in the transport sector as a starting point, this paper reviews all recent environmental policies relating to the automobile industry and employs a scenario analysis to estimate different emissions inventories for different development strategies. The new policy scenario considers all possible mitigation options available to the road transport sector from a bottom up perspective and examines the effects for fuel efficiency improvement and the cost of these mitigation options - vehicle technology improvement, bus rapid transit system and fuel switching, through which the carbon dioxide emissions reduction potential is estimated. Not only does this paper indicate that a large emissions reduction potential exists in China's road transport sector, but it implies that vehicle technology improvement, especially engine technology is likely to be the most effective means to meet emissions reduction targets. This paper concludes by identifying key barriers to implementing those options in China and deduces the technical, financial and institutional aspects of the demand in China for national capacity building and international aid in order to achieve the emissions reduction goals

Road Transportable Analytical Laboratory (RTAL) system

1995-01-01

U.S. Department of Energy (DOE) facilities around the country have, over the years, become contaminated with radionuclides and a range of organic and inorganic wastes. Many of the DOE sites encompass large land areas and were originally sited in relatively unpopulated regions of the country to minimize risk to surrounding populations. In addition, wastes were sometimes stored underground at the sites in 55-gallon drums, wood boxes or other containers until final disposal methods could be determined. Over the years, these containers have deteriorated, releasing contaminants into the surrounding environment. This contamination has spread, in some cases polluting extensive areas. The DOE would benefit greatly if it had reliable, road transportable, fully independent laboratory systems that could perform on-site the full range of analyses required. The goal of the Road Transportable Analytical Laboratory (RTAL) project is the development and demonstration of a system to meet the unique needs of the DOE for rapid, accurate analysis of a wide variety of hazardous and radioactive contaminants in soils, ground water and surface waters. This document describes the requirements for such a laboratory

2009-01-01

Rapid growth of road vehicles, private vehicles in particular, has resulted in continuing growth in China's oil demand and imports, which has been widely accepted as a major factor effecting future oil availability and prices, and a major contributor to China's GHG emission increase. This paper is intended to analyze the future trends of energy demand and GHG emissions in China's road transport sector and to assess the effectiveness of possible reduction measures. A detailed model has been developed to derive a reliable historical trend of energy demand and GHG emissions in China's road transport sector between 2000 and 2005 and to project future trends. Two scenarios have been designed to describe the future strategies relating to the development of China's road transport sector. The 'Business as Usual' scenario is used as a baseline reference scenario, in which the government is assumed to do nothing to influence the long-term trends of road transport energy demand. The 'Best Case' scenario is considered to be the most optimized case where a series of available reduction measures such as private vehicle control, fuel economy regulation, promoting diesel and gas vehicles, fuel tax and biofuel promotion, are assumed to be implemented. Energy demand and GHG emissions in China's road transport sector up to 2030 are estimated in these two scenarios. The total reduction potentials in the 'Best Case' scenario and the relative reduction potentials of each measure have been estimated

Transportation-related risk factors are a major source of morbidity and mortality in China, where expansion of road networks and surges in personal vehicle ownership are having profound effects on public health. Road traffic injuries and fatalities have increased alongside motorized transport in China, and accident injury risk is aggravated by inadequate emergency response systems and trauma care. National air quality standards and emission control technologies are having a positive effect, yet persistent air pollution is increasingly attributable to a growing and outdated vehicle fleet, and famously congested roads. Urban design favors motorized transport, and physical activity and its associated health benefits are hindered by poor urban infrastructure. Transport emissions of greenhouse gases contribute substantially to regional and global climate change, which compound public health risks from multiple factors. Despite these complex challenges, technological advances and innovations in planning and policy stand to make China a leader in sustainable, healthy transportation. PMID:29047445

2014-12-01

Full Text Available The underlying port operations in Durban, South Africa, epitomise intense global competitiveness in the intermodal logistics chain. The link between containerisation and theroad transport network can falter as a result of the dynamics of the logistics system. The main objective of the study was to establish the extent of the intermodal challenges of logistical systems on containerisation to which the role of intermodal sea–road freight transportation enhances the logistical competitiveness. It further examined the intermodal relationship on containerised freight between the challenges of containerisation processes and the effects on road freight transport mode. The impact of containerisation on intermodalism, the sea–road freight transport network and the technological attributes of security-based systems and logistical tracking protocols influence the systematic movement of containers on Durban’s public roads.

Optimizing transport logistics taking into account the state of roads and road traffic

Full Text Available The choice and use of rational routes at strict observance of deliveries terms help to achieve not only minimization of operational expenses, but also to reduce commodity and production stocks in warehouses by 1,5...2 times. Therefore special relevance is gained by the works allowing precisely calculating the volumes of a cargo transportation, to count the quantity of transport units necessary for providing cargo flow, to define the rational routes of transportation, and also to reduce total costs of transportation. On the basis of the analysis of the known mathematical methods applied in transport logistics, the authors drew a conclusion that the route of freight delivery is estimated according to the distance passed by the vehicle. However the time of freight delivery depends not only on distance, but also on a set of other factors, such as vehicle type, road capacity, intensity of transport stream, weather conditions, season and others. For taking note of additional factors when optimizing a freight delivery route the method of analogy and similarity is used by the authors. The transportation parameters were estimated by analogy with an electric chain. For this purpose the authors entered the new concepts “fictitious distance” and “conductivity of the road”. The mathematical model allowing optimizing the organization of freight delivery taking into account not only distances, but also the probable speed of the vehicle movement depending on the road quality, intensity of transport stream and weather conditions is developed. Further development of the system of decision-making support while choosing the optimum route of cargo delivery is planned.

Energy intensity in road freight transport of heavy goods vehicles in Spain

International Nuclear Information System (INIS)

Andrés, Lidia; Padilla, Emilio

2015-01-01

This paper examines the factors that have influenced the energy intensity trend of the Spanish road freight transport of heavy goods vehicles over the period 1996–2012. This article aims to contribute to a better understanding of these factors and to inform the design of measures to improve energy efficiency in road freight transport. The paper uses both annual single-period and chained multi-period multiplicative LMDI-II decomposition analysis. The results suggest that the decrease in the energy intensity of Spanish road freight in the period is explained by the change in the real energy intensity index (lower energy consumption per tonne-kilometre transported), which is partially offset by the behaviour of the structural index (greater share in freight transport of those commodities the transportation of which is more energy intensive). The change in energy intensity is analysed in more depth by quantifying the contribution of each commodity through the attribution of changes in Divisia indices. -- Highlights: •We examine energy intensity of Spanish road freight transport over 1996–2012. •We employ single-period and chained multi-period multiplicative LMDI-II decomposition. •Energy intensity reduction is explained by the change in real energy intensity index. •This is partially offset by the behaviour of the structural index. •The attribution of Divisia indices changes gives the contribution of each commodity

Who is in control of road safety? A STAMP control structure analysis of the road transport system in Queensland, Australia.

Science.gov (United States)

Salmon, Paul M; Read, Gemma J M; Stevens, Nicholas J

2016-11-01

Despite significant progress, road trauma continues to represent a global safety issue. In Queensland (Qld), Australia, there is currently a focus on preventing the 'fatal five' behaviours underpinning road trauma (drug and drink driving, distraction, seat belt wearing, speeding, and fatigue), along with an emphasis on a shared responsibility for road safety that spans road users, vehicle manufacturers, designers, policy makers etc. The aim of this article is to clarify who shares the responsibility for road safety in Qld and to determine what control measures are enacted to prevent the fatal five behaviours. This is achieved through the presentation of a control structure model that depicts the actors and organisations within the Qld road transport system along with the control and feedback relationships that exist between them. Validated through a Delphi study, the model shows a diverse set of actors and organisations who share the responsibility for road safety that goes beyond those discussed in road safety policies and strategies. The analysis also shows that, compared to other safety critical domains, there are less formal control structures in road transport and that opportunities exist to add new controls and strengthen existing ones. Relationships that influence rather than control are also prominent. Finally, when compared to other safety critical domains, the strength of road safety controls is brought into question.

Energy and exergy utilization in transportation sector of Saudi Arabia

International Nuclear Information System (INIS)

Dincer, I.; Hussain, M.M.; Al-Zaharnah, I.

2004-01-01

In this paper we present an analysis of energy and exergy utilization in the transportation sector of Saudi Arabia by considering the sectoral energy and exergy flows for the years of 1990-2001. Energy and exergy analyses are conducted for its three subsectors, namely road, air and marine, and hence the energy and exergy efficiencies are obtained for comparison. Road subsector appears to be the most efficient one compared to air and marine subsectors. It is found that the energy efficiencies in air and marine subsectors are found to be equal to the corresponding exergy efficiencies due to the values of exergy grade function. A comparison of the overall energy and exergy efficiencies of Saudi Arabian transportation sector with the Turkish transportation sector is also presented for the year 1993 based on the data available. Although the sectoral coverage is not same for both countries, it is still useful to illustrate the situation on how subsectoral energy and exergy efficiencies vary over the years. Turkish transportation sector appears to be a bit more efficient for that particular year. It is believed that the present technique is practical and useful for analyzing sectoral energy and exergy utilization to determine how efficient energy and exergy are used in transportation sector. It is also be helpful to establish standards, based on exergy, to facilitate applications in industry and in other planning processes such as energy planning

2015-03-10

We present in this paper a model of vehicular traffic flow for a multimodal transportation road network. We introduce the notion of class of vehicles to refer to vehicles of different transport modes. Our model describes the traffic on highways (which may contain several lanes) and network transit for pubic transportation. The model is drafted with Eulerian and Lagrangian coordinates and uses a Logit model to describe the traffic assignment of our multiclass vehicular flow description on shared roads. The paper also discusses traffic streams on dedicated lanes for specific class of vehicles with event-based traffic laws. An Euler-Lagrangian-remap scheme is introduced to numerically approximate the model’s flow equations.

Valuation of health effects of air pollution is becoming a critical component of the performance of cost-benefit analysis of pollution control measures, which provides a basis for setting priorities for action. Beijing has focused on control of transport emission as vehicular emissions have recently become an important source of air pollution, particularly during Olympic games and Post-games. In this paper, we conducted an estimation of health effects and economic cost caused by road transport-related air pollution using an integrated assessment approach which utilizes air quality model, engineering, epidemiology, and economics. The results show that the total economic cost of health impacts due to air pollution contributed from transport in Beijing during 2004-2008 was 272, 297, 310, 323, 298 million US (mean value), respectively. The economic costs of road transport accounted for 0.52, 0.57, 0.60, 0.62, and 0.58% of annual Beijing GDP from 2004 to 2008. Average cost per vehicle and per ton of PM 10 emission from road transport can also be estimated as 106 US /number and 3584 US $ t -1, respectively. These findings illustrate that the impact of road transport contributed particulate air pollution on human health could be substantial in Beijing, whether in physical and economic terms. Therefore, some control measures to reduce transport emissions could lead to considerable economic benefit.

Climate policies for road transport revisited (II): Closing the policy gap with cap-and-trade

International Nuclear Information System (INIS)

Flachsland, Christian; Brunner, Steffen; Edenhofer, Ottmar; Creutzig, Felix

2011-01-01

Current policies in the road transport sector fail to deliver consistent and efficient incentives for greenhouse gas abatement (see companion article by ). Market-based instruments such as cap-and-trade systems close this policy gap and complement traditional policies that are required where specific market failures arise. Even in presence of strong existing non-market policies, cap-and-trade delivers additional abatement and efficiency by incentivizing demand side abatement options. This paper analyzes generic design options and economic impacts of including the European road transport sector into the EU ETS. Suitable points of regulation are up- and midstream in the fuel chain to ensure effectiveness (cover all emissions and avoid double-counting), efficiency (incentivize all abatement options) and low transaction costs. Based on year 2020 marginal abatement cost curves from different models and current EU climate policy objectives we show that in contrast to conventional wisdom, road transport inclusion would not change the EU ETS allowance price. Hence, industrial carbon leakage induced by adding road transport to the EU ETS may be less important than previously estimated. - Research highlights: → We analyze the rationale, design and economic impacts of including road transportation into GHG cap-and-trade systems. → Suitable points of regulation are up- and mid-stream. → Including European road transport into the EU ETS by 2020 would not change the EU allowance price.

ROAD AND ROADSIDE FEATURE EXTRACTION USING IMAGERY AND LIDAR DATA FOR TRANSPORTATION OPERATION

Directory of Open Access Journals (Sweden)

S. Ural

2015-03-01

Full Text Available Transportation agencies require up-to-date, reliable, and feasibly acquired information on road geometry and features within proximity to the roads as input for evaluating and prioritizing new or improvement road projects. The information needed for a robust evaluation of road projects includes road centerline, width, and extent together with the average grade, cross-sections, and obstructions near the travelled way. Remote sensing is equipped with a large collection of data and well-established tools for acquiring the information and extracting aforementioned various road features at various levels and scopes. Even with many remote sensing data and methods available for road extraction, transportation operation requires more than the centerlines. Acquiring information that is spatially coherent at the operational level for the entire road system is challenging and needs multiple data sources to be integrated. In the presented study, we established a framework that used data from multiple sources, including one-foot resolution color infrared orthophotos, airborne LiDAR point clouds, and existing spatially non-accurate ancillary road networks. We were able to extract 90.25% of a total of 23.6 miles of road networks together with estimated road width, average grade along the road, and cross sections at specified intervals. Also, we have extracted buildings and vegetation within a predetermined proximity to the extracted road extent. 90.6% of 107 existing buildings were correctly identified with 31% false detection rate.

Trends of energy efficiency in Finnish road freight transport 1995-2009 and forecast to 2016

Liimatainen, Heikki; Poellaenen, Markus [Department of Business Information Management and Logistics, Tampere University of Technology, P.O. Box 541, 33101 Tampere (Finland)

2010-12-15

A framework for modeling and analyzing the energy efficiency of road freight transport is presented in this paper. This framework is tested by using the data from the Finnish Goods Transport by Road statistics. The data was enhanced by calculating the fuel consumption for each trip in the data. To calculate this, weight-fuel consumption functions were estimated for each Euro-class vehicles and road type. This is a new method for analyzing the energy efficiency of road freight transport and it could be applied also in other countries gathering freight transport data with continuous company surveys. The analysis show that the energy efficiency of road freight transport in Finland improved during 1995-2002, but has declined since. The major drivers in the development have been the changes in the level of empty running and vehicle fuel efficiency. Extrapolating current statistical trends of factors that influence the energy efficiency show that the target set by the Finnish government for improving energy efficiency by 9% until 2016 will not be achieved. However, the target is possible to be achieved by a combination of small changes to some determinants. (author)

Internationalisation in Road Transport of Goods in Norway: Safety Outcomes, Risk Factors and Policy Implications

2017-09-01

Full Text Available The European Union (EU promotes a gradual lifting of restrictions on foreign hauliers involved in domestic road transport of goods (cabotage, and liberalization of the current road cabotage rules may further increase the proportion of foreign heavy goods vehicles (HGVs on Norwegian roads. The aims of the present study are to: (1 Examine the safety outcomes of increasing internationalisation in (Norwegian road transport of goods; and (2 Discuss the importance of potential risk factors related to increasing proportions of foreign HGVs on Norwegian roads. We use four data sources to shed light on the aims. Results show that foreign HGVs account for 6% of the average domestic transport in Norway, and 11% of the HGVs involved in personal injury accidents. Additionally, foreign HGVs have a three times higher risk of single vehicle accidents, and twice the risk of head-on collisions. Foreign HGV drivers also seem more likely to trigger fatal accidents. We conclude that two risk factors seem to be important: (1 experience with/competence on Norwegian roads and (2 winter driving. Thus, the safety challenge is not that the drivers are foreign, but that they to some extent lack experience with, and competence on, the Norwegian road networks and the challenges that these roads may pose (e.g., narrow roads with high gradients, many curves, snow and ice. Previous research from other countries has also found that lacking experience with national road networks is an important risk factor. Given our results on risk factors, we may hypothesize that if foreign HGV drivers get more experience and education on Norwegian driving conditions, then increased internationalization could perhaps be of less concern in road safety. When discussing the higher accident risk and lower experience of foreign HGV drivers in Norway, it is important to note that the reason for foreign HGV drivers, working for foreign hauliers, to drive in Norway is that there are customers of the

STUDY ABOUT THE ROAD TRANSPORTATION COSTS AND FISCALITY IN THE ROMANIAN COMPANIES

Directory of Open Access Journals (Sweden)

Violeta Isai

2013-12-01

Full Text Available The economic development of the European countries in the second half of the XXth century, and also the increase of commercial international exchanges, generated the transportation development in general, and especially the road transportation. The road transports knew an ascendant evolution due to their advantages: superior mobility; fast adaptability to every land conditions, without special investments; the capacity to complete the other modalities of transportation, in order to achieve the transportation chain; the only one type or transportation which can be done by self; the insurance of wares perishability, without require supplementary manipulations during the transportation. It’s obvious that, there are also negative aspects like: pollution and supplementary fuel consumption. On the level of Romanian companies, transports rise problems related on their costs, the costs structure and the directions to make this activity profitable.The Romanian government established fiscal measures, in order to make the companies more responsible in the vehicles use and their efficient exploitation.

Road transportation impact on Ghana's future energy and environment

Energy Technology Data Exchange (ETDEWEB)

Faah, George

2008-11-07

This research work explored the environmental and socio-economic benefits derived, if some proportion of daily passenger trips made using private cars in Ghana could be shifted to the use of public transport. The research applied the computer software COPERT III in estimating road transport Greenhouse gas (GHG) emissions and fuel consumption in Ghana for the base year 2005 and forecast years 2010 and 2020. The research reveals that if no major change occur in policies or economic determinants in meeting road transport and energy in Ghana, then the 2005 total emissions value is expected to rise by 36% in 2010 and over double in 2020 i.e. from 4.6 to 6.25 in 2010 and to 9.77 Mt CO{sub 2}e in 2020. However, if just 10% of daily passenger trips using private cars can be shifted towards the use of public transport, then the end results in reduction in emissions could earn Ghana about USD 6.6million/year under the Kyoto Protocol CDM initiative. The research also demonstrated that with a further 10% daily passenger trip shift, the outcome could be more promising, increasing to USD 13million/year. (orig.)

GHG emissions inventory for on-road transportation in the town of Sassari (Sardinia, Italy)

Science.gov (United States)

Sanna, Laura; Ferrara, Roberto; Zara, Pierpaolo; Duce, Pierpaolo

2016-04-01

The IPCC Fifth Assessment Report (AR5) accounts an increase of the total annual anthropogenic GHG emissions between 2000 and 2010 that directly came from the transport sector. In 2010, 14% of GHG emissions were released by transport and fossil-fuel-related CO2 emissions reached about 32 GtCO2 per year. The report also considers adaptation and mitigation as complementary strategies for reducing the risks of climate change for sustainable development of urban areas. This paper describes the on-road traffic emission estimated in the framework of a Sardinian regional project [1] for the town of Sassari (Sardinia, Italy), one of the Sardinian areas where the fuel consumption for on-road transportation purposes is higher [2]. The GHG emissions have been accounted (a) by a calculation-based methodology founded on a linear relationship between source activity and emission, and (b) by the COPERT IV methodology through the EMITRA (EMIssions from road TRAnsport) software tool [3]. Inventory data for annual fossil fuel consumption associated with on-road transportation (diesel, gasoline, gas) have been collected through the Dogane service, the ATP and ARST public transport services and vehicle fleet data are available from the Public Vehicle Database (PRA), using 2010 as baseline year. During this period, the estimated CO2 emissions accounts for more than 180,000 tCO2. The calculation of emissions due to on-road transport quantitatively estimates CO2 and other GHG emissions and represents a useful baseline to identify possible adaptation and mitigation strategies to face the climate change risks at municipal level.

Matos, Fernando J.F.; Silva, Francisco J.F.

2011-01-01

Because a large proportion of total operating costs for transportation companies goes towards energy, a reduction in energy operating costs, brought about by an increase in fleet fuel efficiency, or an increase in operational efficiency, results in a change in the relative cost of road freight transportation. This fact could result in an increase in the demand for such services. If this is true, the result would be an increase in total fuel consumption. Consequently, that part of the energy savings obtained through the increased energy efficiency would be lost. The existence of a 'Rebound Effect' is especially important in the road freight transportation sector and is crucial for the definition of a national energy policy. In this study, data from the road freight transportation sector in Portugal for the years of 1987 through 2006 was analyzed. It was determined that an increase in energy efficiency did not cause a backfire, but did cause a total direct rebound effect of 24.1%. In addition, fleet operators were more inclined to adopt operational efficiencies than technological fuel efficiencies as a means of increasing the total operational efficiency. - Research highlights: → We estimate a direct rebound effect for road freight transportation in Portugal. → The functional form chosen was a log-log model and the estimation method used was the two stage least squares model. → Increasing energy efficiency by 1% results in a reduction of 0.759% in energy consumption (a direct rebound effect of about 24.1%). → Estimates of reduced fuel consumption without considering the direct rebound effect may be overestimated by about 0.87 million liters of diesel per year for each percentage point increase in energy efficiency.

Dynamic linkages between road transport energy consumption, economic growth, and environmental quality: evidence from Pakistan.

Science.gov (United States)

Danish; Baloch, Muhammad Awais

2018-03-01

The focus of the present research work is to investigate the dynamic relationship between economic growth, road transport energy consumption, and environmental quality. To this end, we rely on time series data for the period 1971 to 2014 in the context of Pakistan. To use sulfur dioxide (SO 2 ) emission from transport sector as a new proxy for measuring environmental quality, the present work employs time series technique ARDL which allows energy consumption from the transport sector, urbanization, and road infrastructure to be knotted by symmetric relationships with SO 2 emissions and economic growth. From the statistical results, we confirm that road infrastructure boosts economic growth. Simultaneously, road infrastructure and urbanization hampers environmental quality and causes to accelerate emission of SO 2 in the atmosphere. Furthermore, economic growth has a diminishing negative impact on total SO 2 emission. Moreover, we did not find any proof of the expected role of transport energy consumption in SO 2 emission. The acquired results directed that care should be taken in the expansion of road infrastructure and green city policies and planning are required in the country.

Sobrino, Natalia; Monzon, Andres

2014-01-01

Road traffic is the greatest contributor to the carbon footprint of the transport sector and reducing it has become one of the main targets of sustainable transport policies. An analysis of the main factors influencing greenhouse gas (GHG) emissions is essential for designing new energy- and environmentally efficient strategies for the road transport. This paper addresses this need by (i) identifying factors which influence the carbon footprint, including traffic activity, fuel economy and socioeconomic development; and (ii) proposing a methodological framework which uses Modified Laspeyres Index decomposition to analyze the effect of important drivers on the changes in emissions of road transport in Spain during the period from 1990 to 2010. The results demonstrate that the country's economic growth has been closely linked to the rise in GHG emissions. The innovative contribution of this paper is the special analysis of the changes in mobility patterns and GHG emissions during the economic crisis, when, for the first time, Spanish road traffic emissions decreased. The reduction of road transport and improved energy efficiency has been powerful contributors to this decrease, demonstrating the effectiveness of energy-saving measures. On the basis of this analysis, several tailored policy recommendations have been suggested for future implementation. - Highlights: • Drivers contributing to GHG emissions of road transport are identified and analyzed. • Decomposition analysis based on Modified Laspeyres Index (MLI) is applied to the Spanish case. • Economic crisis and changes in mobility patterns and GHG emissions are analyzed. • Policies for the decarbonization of road transport are recommended

The road transport sector is the largest consumer of commercial fuel energy within the transportation system in India and accounts for nearly 35% of the total liquid commercial fuel consumption by all sectors. Gasoline and diesel consumption for road transportation have quadrupled between 1980 and 2000 due to about nine times increase in the number of vehicles and four-fold increase in freight and passenger travel demands. The paper elaborates the trends of energy consumption and consequent emissions of greenhouse gases such as CO 2 , CH 4 and N 2 O and ozone precursor gases like CO, NO x and NMVOC in the road transport sector in India for the period from 1980 to 2000. For the first time, efforts have been made to apportion the fuels, both diesel and gasoline, across different categories of vehicles operating on the Indian roads. In order to generate more comprehensive and complete emission estimates, additionally, other minor fuel types like light diesel oil and fuel oil along with lubricants have also been taken into account. Emission estimates have revealed that nearly 27 Mt of CO 2 were emitted in 1980, increasing to about 105 Mt in 2000. Similar trends have also been observed for other gases. Further scope for improvements in emission estimation is possible by generating country specific emission factors for different vehicle categories and improvement in documentation of fuel consumption at segregated levels by fuel types and vehicle types

This paper is an account of work performed within a multi-lateral research project on the radiological risks associated with the transportation of Type A packaged radioactive material. The research project has been performed on behalf of the European Commission and various national agencies of the participating countries and involved organizations and institutes of five EU Member States, France, Germany, The Netherlands, Sweden, and the UK. The main objectives of the research project were the assessment and appraisal of the potential radiological risks of road transport accidents involving Type A package shipments in participating EU Member States. Data were collected and include harmonized sets information related to the type, quantity and characteristics of Type A package shipments by road. Such databases were basically non-existent until recently. The results are expected to be valuable to both national agencies and international organizations, with responsibilities for the safe transport of radioactive materials by providing some insight in the carriage of radioactive materials by road making up a major fraction of radioactive material transports. Similarly, a wide body of information has been collected and compiled on road transport accidents in terms of the frequency of occurrence and the severity of accidental impact loads potentially experienced by a Type A package.In addition, the results will facilitate judgement of the adequacy of the IAEA Transport Regulations as far as Type A packages are concerned.

Taxes to influence energy use in road transportation in Australia

Directory of Open Access Journals (Sweden)

Pearce Prafula

2017-01-01

Full Text Available The desire to achieve a shift towards renewable energy will be difficult to achieve without a change in the energy use in road transportation in Australia. The transport sector in Australia is heavily reliant on oil and is responsible for contributing 18.1%, of Australia's annual greenhouse gas emissions. This paper examines the current Australian tax policy and its inability to make an impact on transport choices that would reduce energy use and emissions and promote alternative energy use. Some of the current taxes such as the luxury car tax can be singled out as a tax that has passed its “use-by” date. The paper explores how the Australian Government can use targeted taxation measures in order to encourage the purchase of low energy consumption and low-emission vehicles, reduce the number of registered cars on Australian roads and control the use of cars as a means of personal transportation. A comprehensive tax measure suggested in this paper is the luxury energy tax based on the premise that energy use in transportation is a luxury and should be taxed appropriately in order to curb its use and bring about a behaviour change in the choice and usage of motor vehicles.

the application of satellite Earth Observation (EO) methods to the analysis of transportation networks. Other geospatial technologies, including geographic information systems (GIS) and the Global Positioning System (GPS), sharply enhance the utility of EO data in identifying potential road hazards and providing an objective basis for allocating resources to reduce their risks. In combination, these powerful information technologies provide substantial public benefits and increased business opportunities to remote sensing value-added firms. departments in rural jurisdictions improve the trafficability of the roads under their management during severe weather. We are developing and testing these methods in the U.S. Southwest, where thousands of kilometers of unimproved and graded dirt roads cross Native American reservations.

Improved Cost Management at Small and Medium Sized Road Transport Companies: Case Hungary

Directory of Open Access Journals (Sweden)

Zoltan Bokor

2015-10-01

Full Text Available Small and medium sized road freight transport companies located in Hungary are facing strong competition on the logistics market. An advanced cost management system supporting decisions on capacity allocations or pricing may be a competitive advantage for them and indirectly for the whole economy as well. Still, they generally apply simple, traditional cost calculation regimes, potentially sufficient in case of a homogeneous service portfolio. Nevertheless, road haulage companies with heterogeneous service structures may witness information distortions when using traditional costing methods. So it might be recommended for them to introduce better costing principles. To support an improved transport costing, a multi-level full cost allocation model has been set up and tested in this paper. The research results have pointed out that such a methodological development accompanied by the extension of the data collection mechanism can contribute to making the cost management systems of road freight transport companies more effective.

Dzikuć, Maciej; Adamczyk, Janusz; Piwowar, Arkadiusz

2017-07-01

According to the report of the World Health Organization (WHO) on the list of 50 cities with the most polluted air in Europe as many as 33 are located in Poland. All the cities that are on the list exceed the maximum concentration of dust recommended by WHO at least three times. In the Lubuskie Province there is a very serious problem of maintaining good air quality. The air in Poland is among the most polluted in the European Union and this also applies to less-industrialized areas, such as Lubuskie, where the concentration levels of substances hazardous to human health and the environment are recorded as exceeded. One of the main factors affecting the poor air quality in the region is road transport. It is not just a problem near roads with heavy traffic, but also applies to the cities, where there is a large movement of cars, which are often old and do not meet current environmental standards. This article aims to identify the main sources of low emission from road transport and identify potential solutions to help reduce emission from this sector. The actions aimed at limiting low emission from road transport can bring a significant positive ecological effect. The aim of this article is to review one of the main sources of low emission in the province of Lubuskie, which is transportation. Moreover, the authors of the paper indicate the main problems associated with the emission coming from road transport and describe the possibilities for opportunities to reduce pollution from this sector. In addition, the article presents the three-scenario simulation of annual emissions from passenger cars that could take place in 2020.

Zhang, Yue-Jun; Peng, Hua-Rong; Liu, Zhao; Tan, Weiping

2015-01-01

The transport sector appears a main energy consumer in China and plays a significant role in energy conservation. Improving energy efficiency proves an effective way to reduce energy consumption in transport sector, whereas its effectiveness may be affected by the rebound effect. This paper proposes a dynamic panel quantile regression model to estimate the direct energy rebound effect for road passenger transport in the whole country, eastern, central and western China, respectively, based on the data of 30 provinces from 2003 to 2012. The empirical results reveal that, first of all, the direct rebound effect does exist for road passenger transport and on the whole country, the short-term and long-term direct rebound effects are 25.53% and 26.56% on average, respectively. Second, the direct rebound effect for road passenger transport in central and eastern China tends to decrease, increase and then decrease again, whereas that in western China decreases and then increases, with the increasing passenger kilometers. Finally, when implementing energy efficiency policy in road passenger transport sector, the effectiveness of energy conservation in western China proves much better than that in central China overall, while the effectiveness in central China is relatively better than that in eastern China. - Highlights: • The direct rebound effect (RE) for road passenger transport in China is estimated. • The direct RE in the whole country, eastern, central, and western China is analyzed. • The short and long-term direct REs are 25.53% and 26.56% within the sample period. • Western China has better energy-saving performance than central and eastern China.

This study determined whether transporting lambs on paved (PR) or unpaved roads (UR) for 3 h had an effect on plasma stress indicators (cortisol, lactate, glucose, creatine kinase [CK], red blood cells, white blood cells, hematocrit, and neutrophil/lymphocyte [N/L] ratio) and instrumental meat quality (pH24, bruising score, water holding capacity [WHC], color, and texture). A total of 48 Rasa Aragonesa male lambs were used that were approximately 100 days old (12.5 kg ± 1.64, carcass weight). The results suggest that transport on unpaved roads had a significant influence on physiological and hematological stress parameters. Road type had a significant effect on all variables, except for white and red blood cells, and hematocrit levels. The UR lambs had significantly higher (at least p ≤ 0.01) cortisol, lactate, glucose, and CK levels and a higher N/L ratio than PR lambs. Meat from UR lambs had some dark-cutting characteristics, with a darker color, higher ultimate pH, and higher tenderness values than PR. In conclusion, lambs transported on unpaved roads had a more intense stress response and poorer meat quality than lambs transported on paved roads. An effort to improve the logistics associated with route planning is necessary to prevent welfare problems during transport to slaughter.

Reforming the road freight transportation system using systems thinking: An investigation of Coronial inquests in Australia.

Science.gov (United States)

Newnam, Sharon; Goode, Natassia; Salmon, Paul; Stevenson, Mark

2017-04-01

Road freight transport is considered to be one of the most dangerous industries in Australia, accounting for over 30% of all work fatalities. Whilst system reform (i.e., change to policy and practice) is needed, it is not clear what this reform should be, or what approaches should be used to drive it. This article argues that road freight transportation reform should be underpinned by a systems thinking approach. Efforts to understand crash causation should be focused beyond the driver and identify contributing factors at other levels with the road freight system. Accordingly, we present the findings from a study that examined whether Australian Coronial investigations into road freight crashes reflect support appropriate system reform. Content analysis was used to identify the contributing factors and interrelations implicated in the road freight crashes described in publicly available Australian Coroner's inquest reports from the last 10 years (2004-2014; n=21). The results found evidence to suggest that the Coronial inquests provide some understanding of the complex system of factors influencing road freight transportation crashes in Australia. However, there was a lack of evidence to suggest an understanding of system-based reform based on the identification of reductionist-focused recommendations. It is concluded that researchers and practitioners (ie., government and industry) need to work together to develop prevention efforts focused on system reforms. Systems thinking based data collection and analysis frameworks are urgently required to help develop this understanding in road freight transportation. Copyright © 2017 Elsevier Ltd.

Impacts of urbanization on national transport and road energy use: Evidence from low, middle and high income countries

International Nuclear Information System (INIS)

Poumanyvong, Phetkeo; Kaneko, Shinji; Dhakal, Shobhakar

2012-01-01

Few attempts have been made to investigate quantitatively and systematically the impact of urbanization on transport energy use for countries of different stages of economic development. This paper examines the influence of urbanization on national transport and road energy use for low, middle and high income countries during 1975–2005, using the Stochastic Impacts by Regression on Population, Affluence and Technology (STIRPAT) model. After controlling for population size, income per capita and the share of services in the economy, the main results suggest that urbanization influences national transport and road energy use positively. However, the magnitude of its influence varies among the three income groups. Changes in urbanization appear to have a greater impact on transport and road energy use in the high income group than in the other groups. Surprisingly, the urbanization elasticities of transport and road energy use in the middle income group are smaller than those of the low income group. This study not only sheds further light on the existing literature, but also provides policy makers with insightful information on the link between urbanization and transport energy use at the three different stages of development. - Highlights: ► Overall, urbanization increases national transport and road energy use. ► Urbanization elasticities of transport energy use differ across development stages. ► Urbanization elasticities in high-income group are higher than in other groups.

Trends of energy efficiency in Finnish road freight transport 1995-2009 and forecast to 2016

International Nuclear Information System (INIS)

Liimatainen, Heikki; Poellaenen, Markus

2010-01-01

A framework for modeling and analyzing the energy efficiency of road freight transport is presented in this paper. This framework is tested by using the data from the Finnish Goods Transport by Road statistics. The data was enhanced by calculating the fuel consumption for each trip in the data. To calculate this, weight-fuel consumption functions were estimated for each Euro-class vehicles and road type. This is a new method for analyzing the energy efficiency of road freight transport and it could be applied also in other countries gathering freight transport data with continuous company surveys. The analysis show that the energy efficiency of road freight transport in Finland improved during 1995-2002, but has declined since. The major drivers in the development have been the changes in the level of empty running and vehicle fuel efficiency. Extrapolating current statistical trends of factors that influence the energy efficiency show that the target set by the Finnish government for improving energy efficiency by 9% until 2016 will not be achieved. However, the target is possible to be achieved by a combination of small changes to some determinants. - Research highlights: →A new method for analyzing energy efficiency by adding fuel data to national freight statistics. →Energy efficiency improved in Finland from 1995 to 2002 but has declined since. →Energy efficiency in Finland is still on a good level internationally. →Target of the Finnish energy efficiency agreement was quantified for the first time in this study. →The target will not be achieved if the past trends continue.

Energy for sustainable road transportation in China: Challenges, initiatives and policy implications

This paper presents an overview of the initiatives launched in energy supply and consumption and the challenges encountered in sustainable road transportation development in China. It analyzes the main energy challenges related to road transportation development arising in the context of economic development, rapid urbanization, and improvement in living standards. It also discusses technological- and policy initiatives needed to deal with these challenges, drawing comparisons with foreign experience: promoting the development and dissemination of alternative fuels and clean vehicles such as: LPG, CNG, EV, HEV, FCV, ethanol, methanol, DME, bio-diesel, and CTL, strengthening regulations relating to vehicle fuel economy and emission, improving traffic efficiency and facilitating public transport development, and strengthening management of the soaring motor vehicle population. If the current pattern continues, by the year 2030, the vehicle population in China will be 400 million and fuel demand will be 350 million tons. The potential energy saving capacity being 60%, the actual oil demand by 2030 from on-road vehicles might technically be kept at the current level by improving fuel economy, propagating use of HEV and diesel vehicles, improving supply of alternative fuels, and developing public transport. Several uncertainties are identified that could greatly influence the effect of the technical proposals: traffic efficiency, central government's resolve, and consumers' choice. (author)

To evaluate if the Swedish Road Administration (SRA) model for a safe road transport system, which includes the interaction between the road user, the vehicle, and the road, could be used to classify fatal car crashes according to some safety indicators. Also, to present a development of the model to better identify system weakness. Real-life crashes with a fatal outcome were classified according to the vehicle's safety rating by Euro NCAP (European Road Assessment Programme) and fitment of ESC (Electronic Stability Control). For each crash, the road was also classified according to EuroRAP (European Road Assessment Programme) criteria, and human behavior in terms of speeding, seat belt use, and driving under the influence of alcohol. Each crash was compared with the model criteria, to identify components that might have contributed to fatal outcome. All fatal crashes where a car occupant was killed that occurred in Sweden during 2004 were included: in all, 215 crashes with 248 fatalities. The data were collected from the in-depth fatal crash data of the Swedish Road Administration (SRA). It was possible to classify 93% of the fatal car crashes according to the SRA model. A number of shortcomings in the criteria were identified since the model did not address rear-end or animal collisions or collisions with stationary/parked vehicles or trailers (18 out of 248 cases). Using the further developed model, it was possible to identify that most of the crashes occurred when two or all three components interacted (in 85 of the total 230 cases). Noncompliance with safety criteria for the road user, the vehicle, and the road led to fatal outcome in 43, 27, and 75 cases, respectively. The SRA model was found to be useful for classifying fatal crashes but needs to be further developed to identify how the components interact and thereby identify weaknesses in the road traffic system. This developed model might be a tool to systematically identify which of the components are

Road transportation impact on Ghana's future energy and environment

Energy Technology Data Exchange (ETDEWEB)

Faah, George

2008-11-07

This research work explored the environmental and socio-economic benefits derived, if some proportion of daily passenger trips made using private cars in Ghana could be shifted to the use of public transport. The research applied the computer software COPERT III in estimating road transport Greenhouse gas (GHG) emissions and fuel consumption in Ghana for the base year 2005 and forecast years 2010 and 2020. The research reveals that if no major change occur in policies or economic determinants in meeting road transport and energy in Ghana, then the 2005 total emissions value is expected to rise by 36% in 2010 and over double in 2020 i.e. from 4.6 to 6.25 in 2010 and to 9.77 Mt CO{sub 2}e in 2020. However, if just 10% of daily passenger trips using private cars can be shifted towards the use of public transport, then the end results in reduction in emissions could earn Ghana about USD 6.6million/year under the Kyoto Protocol CDM initiative. The research also demonstrated that with a further 10% daily passenger trip shift, the outcome could be more promising, increasing to USD 13million/year. (orig.)

Full Text Available Forestry management has activities dealing with technical, economic, social and environmental services. Forestry operations which are carried out on forest areas , an important part of the ecosistem are materialized in open space. This forestry activities on large areas and high sloping generally, include many different techniques. It is needed primarily to the forest road network in terms of forest management. Determining the approriate route in the natural environment, planning and road construction affairs for forest roads which are necessary accessing in forest areas, is also of great importance from an environmental viewpoint as well as technical and economic manner. Forest road planning which can not be changed later and left a permanent mark on the natural environment carries much more importance to the environment especially on sloping land. This is because, it is important choosing correct type of roaf structure, and doing periodic maintenance of the roads. Skidding activities, after wood production, is important in terms of its impact on forest soil and by means of effects on saplings and trees on the releated forest areas.The development of environmental sensitive techniques is difficult, limited or expensive for this wood extraction works which are made more difficult conditons in the sloping terrain. Therefore, especially in using some silvicultural methods wood extraction damages are even greater. In this study; some road planning, road construction and wood extraction techniques which performed by me have been made to examine the environmental aspects. Environment-friendly forest roads and primary transport techniques on the forest ecosystem are briefly explained and discussed in the frame of the environmental aspects.

Bahn, Olivier; Marcy, Mathilde; Vaillancourt, Kathleen; Waaub, Jean-Philippe

2013-01-01

We use a newly developed bottom-up model of the entire Canadian energy system (TIMES-Canada) to assess potentials for electrification of the road transport sector. A special emphasis has been put on the modelling of the Canadian road transport, by considering a variety of vehicles for passenger and freight transportation. Besides a business-as-usual (baseline) scenario, we have analysed an energy policy scenario imposing targets for electric vehicle penetration and a climate policy scenario imposing targets for greenhouse gas emission reduction. Our analysis shows on the one hand that electric vehicles penetrate notably the passenger vehicle market after 2040 in the baseline scenario and after 2030 in the energy policy scenario (following the assumed penetration targets). On the other hand, the assumed climate policy forces a stronger penetration of electric vehicles for passenger transportation, with a progressive phasing out of internal combustion engine vehicles, whereas the latter vehicles remain dominant for freight transportation but with a shift away of fossil fuels and in favour of biofuels. A sensitivity analysis on the (assumed) evolution of electric vehicles over time confirms these general trends. -- Highlights: •We use a newly developed TIMES-Canada model of the entire Canadian energy system. •We assess potentials for electrification of the Canadian road transport sector. •We analyse three scenarios: baseline, energy policy and climate policy. •EVs penetrate notably after 2040 in the baseline and after 2030 in the energy policy scenario. •The climate policy forces a stronger penetration of EVs

Building and improving road infrastructure in Slovakia is currently influenced by the amount of state funding. Therefore, it is necessary to determine the effectiveness of each proposed solution of road project, which is based on life-cycle costs. Besides capital costs, social costs are also important, which valued the negative impacts due to road construction and operation on road users, the environment, and the population living in the affected area. Some components of social costs have shortcomings in quantifying and valuating, which need to be resolved. The one of important components which affects human health and the value of an area, and have some shortcomings are noise costs. Improvement of this component will lead to more accurate valuation of economic efficiency of roads.

Full Text Available An integrated environmental health impact assessment of road transport in New Zealand was carried out, using a rapid assessment. The disease and injury burden was assessed from traffic-related accidents, air pollution, noise and physical (inactivity, and impacts attributed back to modal source. In total, road transport was found to be responsible for 650 deaths in 2012 (2.1% of annual mortality: 308 from traffic accidents, 283 as a result of air pollution, and 59 from noise. Together with morbidity, these represent a total burden of disease of 26,610 disability-adjusted life years (DALYs. An estimated 40 deaths and 1874 DALYs were avoided through active transport. Cars are responsible for about 52% of attributable deaths, but heavy goods vehicles (6% of vehicle kilometres travelled, vkt accounted for 21% of deaths. Motorcycles (1 per cent of vkt are implicated in nearly 8% of deaths. Overall, impacts of traffic-related air pollution and noise are low compared to other developed countries, but road accident rates are high. Results highlight the need for policies targeted at road accidents, and especially at heavy goods vehicles and motorcycles, along with more general action to reduce the reliance on private road transport. The study also provides a framework for national indicator development.

2016-04-01

Surface transportation road networks share structural properties similar to other complex networks (e.g., social networks, information networks, biological networks, and so on). This research investigates the structural properties of road networks for any possible correlation with the traffic characteristics such as link flows those determined independently. Additionally, we define a criticality index for the links of the road network that identifies the relative importance in the network. We tested our hypotheses with two sample road networks. Results show that, correlation exists between the link flows and centrality measures of a link of the road (dual graph approach is followed) and the criticality index is found to be effective for one test network to identify the vulnerable nodes.

Márton Lányi

2018-03-01

Full Text Available This article attempts to reveal the general behavioural norms of cargo carriers, with a predominant emphasis on security issues. The security awareness level of road transporters has been found hugely dependent on management capabilities. Additionally, this poses a risk factor indicative of a shipment load's quantity and value. At a certain level of road transporter development trajectory, broad research delineates a sharp increase in security awareness, stemming from leadership recognition at larger companies. The results of the following research findings are significantly similar to various well respected scientific theories which verify the hypothesis that the principal barrier to developing a company is a combination of a lack of management capabilities and an unwillingness to adapt to change.

2011-01-01

Full Text Available With more stringent requirements for efficient utilization of energy resources within the transport industry a need for implementation of sustainable development principles has appeared. Such action will be one of competitive advantages in the future. This is especially confirmed within the road transport sector. A methodology implemented in public procurement procedures for fleet renewal regarding the calculation of road vehicles’ operational lifecycle costs has been analyzed in detail in this paper. Afore mentioned calculation comprises the costs for: vehicle ownership, energy, carbon dioxide and pollutants emissions. Implementation of this methodology allows making the choice of energy efficient vehicles and vehicles with notable positive environmental effects. The objective of the research is to assess the influence of specific parameters of vehicle operational lifecycle costs, especially energy costs and estimated vehicle energy consumption, on vehicle choice in the procurement procedure. The case of urban bus fleet in Serbia was analyzed. Their operational lifecycle costs were calculated and differently powered vehicles were assessed. Energy consumption input values were defined. It was proved that defined fleet renewal scenarios could influence unquestionable decrease in energy consumption.

Road Transportable Analytical Laboratory (RTAL) system

Finger, S.M.

1995-01-01

U.S. Department of Energy (DOE) facilities around the country have, over the years, become contaminated with radionuclides and a range of organic and inorganic wastes. Many of the DOE sites encompass large land areas and were originally sited in relatively unpopulated regions of the country to minimize risk to surrounding populations. In addition, wastes were sometimes stored underground at the sites in 55-gallon drums, wood boxes or other containers until final disposal methods could be determined. Over the years, these containers have deteriorated, releasing contaminants into the surrounding environment. This contamination has spread, in some cases polluting extensive areas. Remediation of these sites requires extensive sampling to determine the extent of the contamination, to monitor clean-up and remediation progress, and for post-closure monitoring of facilities. The DOE would benefit greatly if it had reliable, road transportable, fully independent laboratory systems that could perform on-site the full range of analyses required. Such systems would accelerate and thereby reduce the cost of clean-up and remediation efforts by (1) providing critical analytical data more rapidly, and (2) eliminating the handling, shipping and manpower associated with sample shipments. The goal of the Road Transportable Analytical Laboratory (RTAL) Project is the development and demonstration of a system to meet the unique needs of the DOE for rapid, accurate analysis of a wide variety of hazardous and radioactive contaminants in soil, groundwater, and surface waters. This laboratory system has been designed to provide the field and laboratory analytical equipment necessary to detect and quantify radionuclides, organics, heavy metals and other inorganic compounds. The laboratory system consists of a set of individual laboratory modules deployable independently or as an interconnected group to meet each DOE site's specific needs

Strategies for a road transport system based on renewable resources - The case of an import-independent Sweden in 2025

Lindfeldt, Erik G.; Saxe, Maria; Magnusson, Mimmi; Mohseni, Farzad

2010-01-01

When discussing how society can decrease greenhouse gas emissions, the transport sector is often seen as posing one of the most difficult problems. In addition, the transport sector faces problems related to security of supply. The aim of this paper is to present possible strategies for a road transport system based on renewable energy sources and to illustrate how such a system could be designed to avoid dependency on imports, using Sweden as an example. The demand-side strategies considered include measures for decreasing the demand for transport, as well as various technical and non-technical means of improving vehicle fuel economy. On the supply side, biofuels and synthetic fuels produced from renewable electricity are discussed. Calculations are performed to ascertain the possible impact of these measures on the future Swedish road transport sector. The results underline the importance of powerful demand-side measures and show that although biofuels can certainly contribute significantly to an import-independent road transport sector, they are far from enough even in a biomass-rich country like Sweden. Instead, according to this study, fuels based on renewable electricity will have to cover more than half of the road transport sector's energy demand.

Roads provide the main means of transportation in Brazil. According to data from the Brazilian Department of Infrastructure and Transport, 96.2% of the passenger transportation and 61.8% of the cargo transportation are based on road infrastructure. However, three quarters of the Brazilian roads are in terrible, unsatisfactory or generally inadequate condition. Poor road conditions are responsible for a great number of accidents with severe consequences for the population and the environment. Given the importance of this matter, there is a need to develop an intelligent system for automatic classification of social and environmental sensitivity maps in order to support actions that respond to emergencies and to help in transportation planning, especially considering the heavy movement of hazardous cargoes such as petroleum and its derivates. For this, tools such as Geographic Information System (GIS) allow social-environmental and traffic engineering characterization maps to be analyzed on a unified, geo referenced digital base. This way, administrators can estimate which stretches of the network are more environmentally sensitive and which pose greater risks, and therefore draw inferences on the most socially and environmentally vulnerable. Social and environmental vulnerability data not only help in the classification of the areas which pose the greater risks, but also make it possible to decide on emergency support points, creating a culture of prevention in the area of hazardous cargo transportation. The case study on the state of Rio Grande do Norte provides a measure of the importance of such work. The city of Natal - the state capital - and the Guamare petrochemical facility are interconnected by 180 Km Road, on which more than 100 tanker trucks loaded with diesel and its derivates travel every day. This road is classified as in poor conditions and, according to the Brazilian Roads Police, it is one of the most dangerous. The relevance of this work is to show

2001-01-01

An assessment and evaluation of the potential radiological risks of transport accidents involving Type A package shipments by road have been performed by five EU Member States, France, Germany, Sweden, The Netherlands, and the UK. The analysis involved collection and analysis of information on a national basis related to the type, volume, and characteristics of Type A package consignments, the associated radioactive traffic, and the expected frequency and consequences of potential vehicular road transport accidents. It was found that the majority of Type A packaged radioactive material shipments by road is related to applications of non-special form radioactive material, i.e. radiopharmaceuticals, radiochemicals etc., in medicine, research, and industry and special form material contained in radiography and other radiation sources, e.g. gauging equipment. The annual volumes of Type A package shipments of radiopharmaceuticals and radiochemicals by road differ considerably between the participating EU Member States from about 12,000 Type A packages in Sweden to about 240,000 in the Netherlands. The broad range reflects to a large extent the supply of radioactive material for the national populations and the production and distribution operations prevailing in the participating EU Member States (some are producer countries, others are not!). Very few standard package designs weighing from about 1-25 kg are predominant in Type A package shipments in all participating countries. Type A packages contain typically a range of radioactivity from a few mega becquerels to a few tens of giga becquerels, the average package activity contents is in terms of fractions of A 2 about 0.01, i.e. about one hundredth of a Type A package contents limits. Based on a probabilistic risk assessment method it has been concluded that the expected frequencies of occurrence of vehicular road transport accidents with the potential to result in an environmental release - including radiologically

The potential of natural gas as a bridging technology in low-emission road transportation in Germany

Directory of Open Access Journals (Sweden)

Wang-Helmreich Hanna

2012-01-01

Full Text Available Greenhouse gas emission reductions are at the centre of national and international efforts to mitigate climate change. In road transportation, many politically incentivised measures focus on increasing the energy efficiency of established technologies, or promoting electric or hybrid vehicles. The abatement potential of the former approach is limited, electric mobility technologies are not yet market-ready. In a case study for Germany, this paper focuses on natural gas powered vehicles as a bridging technology in road transportation. Scenario analyses with a low level of aggregation show that natural gas-based road transportation in Germany can accumulate up to 464 million tonnes of CO2-equivalent emission reductions until 2030 depending on the speed of the diffusion process. If similar policies were adopted EU-wide, the emission reduction potential could reach a maximum of about 2.5 billion tonnes of CO2-equivalent. Efforts to promote natural gas as a bridging technology may therefore contribute to significant emissions reductions.

Measurement of CO2 emissions from road freight transport: A review of UK experience

International Nuclear Information System (INIS)

McKinnon, A.C.; Piecyk, M.I.

2009-01-01

It is possible to estimate CO 2 emissions from road freight transport in different ways, depending on the definition of trucking activity, the degree of reliance on survey, vehicle test-cycle and traffic count data and the geographical scope of the calculation. The emergence of differing road freight-related CO 2 estimates from official sources and revisions to statistical series can frustrate the policy-making process and erode the confidence of industry stakeholders in the validity of the figures. Using UK data, this paper examines the various methods of carbon auditing road freight transport at the national level and compares the results both for a single year (2006) and over a time period. It highlights a series of statistical anomalies and approximations and tries to explain discrepancies that have arisen in the UK data sets. A concluding section considers the general lessons that can be learned from the recent UK experience in this field.

Electric Road Systems: Strategic Stepping Stone on the Way towards Sustainable Freight Transport?

Directory of Open Access Journals (Sweden)

Jesko Schulte

2018-04-01

Full Text Available Electrification of the transport sector has been pointed out as a key factor for tackling some of today’s main challenges, such as global warming, air pollution, and eco-system degradation. While numerous studies have investigated the potential of electrifying passenger transport, less focus has been on how road freight transport could be powered in a sustainable future. This study looks at Electric Road Systems (ERS in comparison to the current diesel system. The Framework for Strategic Sustainable Development was used to assess whether ERS could be a stepping stone on the way towards sustainability. Strategic life-cycle assessment was applied, scanning each life-cycle phase for violations against basic sustainability principles. Resulting sustainability “hot spots” were quantified with traditional life-cycle assessment. The results show that, if powered by renewable energy, ERS have a potential to decrease the environmental impact of freight transport considerably. Environmental payback times of less than five years are achievable if freight traffic volumes are sufficiently high. However, some severe violations against sustainability principles were identified. Still, ERS could prove to be a valuable part of the solution, as they drastically decrease the need for large batteries with high cost and sustainability impact, thereby catalyzing electrification and the transition towards sustainable freight transport.

To evaluate the reduction potential of greenhouse gas and pollutant emissions of the industry in China, its emission inventory was calculated and scenario analysis was created for the period between 2012 and 2030 in this paper. Based on the Long-range Energy Alternatives Planning System (LEAP model, the development of China’s road transportation industry in two scenarios (the business-as-usual (BAU scenario and the comprehensive-mitigation (CM scenario was simulated. In the Comprehensive Mitigation scenario, there are nine various measures which include Fuel Economy Standards, Auto Emission Standards, Energy-saving Technology, Tax Policy, Eco-driving, Logistics Informatization, Vehicle Liquidation, Electric Vehicles, and Alternative Fuels. The cumulative energy and emission reductions of these specific measures were evaluated. Our results demonstrate that China’s road transportation produced 881 million metric tons of CO2 and emitted 1420 thousand tons of CO, 2150 thousand tons of NOx, 148 thousand tons of PM10, and 745 thousand tons of HC in 2012. The reduction potential is quite large, and road freight transportation is the key mitigation subsector, accounting for 85%–92% of the total emission. For energy conservation and carbon emission mitigation, logistics informatization is the most effective method, potentially reducing 1.80 billion tons of coal equivalent and 3.83 billion tons of CO2 from 2012 to 2030. In terms of air pollutant emission mitigation, the auto emission standards measure performs best with respect to NOx, PM10, and HC emission mitigation, and logistic informatization measure is the best in CO emission reduction. In order to maximize the mitigation potential of China’s road transportation industry, the government needs to implement various measures in a timely and strict fashion.

Previous research has emphasized the need to consider the social dimension featuring organizations in order to maximize organizational efficiency (Rasmussen, 1997). In the road transport sector, previous research has focused on the relationship between human factor, stress, fatigue, and other relevant issues, and professional drivers health and safety (p.e., De Croon et al, 2004). However, research on relevant organizational factors is scarce. This study aims to examine the association between leadership and supportive climate, and employees health and safety. Moreover, the impact of stress (time pressure) was also examined because previous research has stressed its importance. This study used a sample of 486 employees from 35 different Spanish companies pertaining to the road transport sector. Findings showed time pressure to be negatively associated to employees health, job satisfaction and satisfaction with safety. Additionally, leadership was positively associated employees health, job satisfaction and satisfaction with safety. Finally, co-workers and supervisors supportive climate was positively associated with job satisfaction and negatively associated to illness. These findings have relevant practical implications for the competitiveness of road transport companies. (Author) 21 refs.

Full Text Available Introduction The most important post-harvest mechanical damage is bruising. Bruising occurs during the stages of handling, transporting and packaging due to quasi-static and dynamic loads. Vibrations of tomato fruits during transportation by truck will decrease their quality. More than 2.5 million tons damages have been reported during tomato transportation in Iran. Therefore, it is necessary to recognize different parameters of damages during road transportation in order to detect and prevent bruising injury. Materials and Methods In this study, healthy Super Queen verity of tomatoes devoid of any corrosion and mechanical damage multipliers were used. Aaverage of 7 and 5 pieces of fruit in each length and width, respectively in 13*25*37 cm boxes with a capacity of 8 kg were arranged. The boxes were divided into 2 types of truck suspension (model M2631 AIMCO, manufactured in 2010 with air suspension and Nissan trucks 2400, manufactured in 2010 with suspension spring. Boxes were established in three different heights truck, floor truck, height of middle and top of truck, in addition to two different situation boxes on the front axle (S1 and rear axle (S2.

For a long time synonymous with independence and freedom, the car and its different uses are now increasingly controlled - or even constrained - by European governments. In the most recent example, on 8 December 2014, the Mayor of Paris Anne Hidalgo stated her wish to eradicate diesel from the streets of Paris (in the next five years) to combat air pollution. Going beyond the impact of the announcement itself, this pollution prevention plan comes on top of a whole series of measures recently implemented in Europe: reduction of the speed limit, congestion charging in London and Stockholm, eco-tax in France, 'environmental bonus' for electric vehicles, etc. These different policies, which are not always clearly aligned, aim to reduce the nuisances caused by road transport without compromising mobility. This note aims to explain them by offering an overview of the main transport policies in Europe. (authors)

Singh, N.; Mishra, T.; Banerjee, R.

2017-12-01

India is one of the fastest growing major economies of the world. It imports three quarters of its oil demand, making transport sector major contributor of greenhouse gas (GHG) emissions. 40% of oil consumption in India comes from transport sector and over 90% of energy demand is from road transport sector. This has led to serious increase in CO2 emission and concentration of air pollutants in India. According to Intergovernmental Panel on Climate Change (IPCC), transport can play a crucial role for mitigation of global greenhouse gas emissions. Therefore, assessment of appropriate mitigation policies is required for emission reduction and cost benefit potential. The present study aims to estimate CO2, SO2, PM and NOx emissions from the road transport sector for the base year (2014) and target year (2030) by applying bottom up emission inventory model. Effectiveness of different mitigation strategies like inclusion of natural gas as alternate fuel, penetration of electric vehicle as alternate vehicle, improvement of fuel efficiency and increase share of public transport is evaluated for the target year. Emission reduction achieved from each mitigation strategies in the target year (2030) is compared with the business as usual scenario for the same year. To obtain cost benefit analysis, marginal abatement cost for each mitigation strategy is estimated. The study evaluates mitigation strategies not only on the basis of emission reduction potential but also on their cost saving potential.

This developmental effort clearly shows that a Road Transportable Analytical Laboratory System is a worthwhile and achievable goal. The RTAL is designed to fully analyze (radioanalytes, and organic and inorganic chemical analytes) 20 samples per day at the highest levels of quality assurance and quality control. It dramatically reduces the turnaround time for environmental sample analysis from 45 days (at a central commercial laboratory) to 1 day. At the same time each RTAL system will save the DOE over $12 million per year in sample analysis costs compared to the costs at a central commercial laboratory. If RTAL systems were used at the eight largest DOE facilities (at Hanford, Savannah River, Fernald, Oak Ridge, Idaho, Rocky Flats, Los Alamos, and the Nevada Test Site), the annual savings would be $96,589,000. The DOE's internal study of sample analysis needs projects 130,000 environmental samples requiring analysis in FY 1994, clearly supporting the need for the RTAL system. The cost and time savings achievable with the RTAL system will accelerate and improve the efficiency of cleanup and remediation operations throughout the DOE complex

Is an increased elderly population related to decreased CO2 emissions from road transportation?

International Nuclear Information System (INIS)

Okada, Akira

2012-01-01

Few studies have focused on the potential effects of an increase in the share of aged population on the environmental impacts of road transportation. In order to fill this gap in the literature, this paper empirically analyzes whether there is a relationship between the share of aged population and carbon dioxide (CO 2 ) emissions from road transportation by applying a quadratic function. Using international panel data, it also addresses the level of the turning point in the relationships between the share of aged population and CO 2 emissions. The analysis in this paper uses a first-order differential equation to estimate an inverted U-shaped relationship between them in order to alleviate the unit roots issue. The results from 25 OECD countries, consisting mainly of European countries and Japan, indicate that there is a quadratic relationship between CO 2 emissions per capita and the share of aged population, and that the turning point is around 16 percent. The results also imply that a relative increase in the number of elderly people is associated with a decrease in CO 2 emissions per capita from the road sector when the share of aged population reaches more than 16 percent. - Highlights: ► I estimate the relationship between a country's share of elderly population and CO 2 emissions from road transport. ► In order to alleviate the unit roots issue, the analysis uses a first-order differential equation to estimate models. ► There is a quadratic relationship between CO 2 emissions per capita and the share of elderly. ► The level of the turning point in terms of the share of elderly in OECD European countries and Japan is around 16 percent.

Most young people killed in road crashes are known as vulnerable road users. A combination of physical and developmental immaturity as well as inexperience increases the risk of road traffic accidents with a high injury severity rate. Understanding injury mechanism and pattern in a group of young road users may reduce morbidity and mortality. This study analyzes injury patterns and outcomes of young road users compared to adult road users. The comparison takes into account different transportation related injury mechanisms. A retrospective analysis using data collected between 2002 and 2012 from the TraumaRegister DGU® was performed. Only patients with a transportation related injury mechanism (motor vehicle collision (MVC), motorbike, cyclist, and pedestrian) and an ISS ≥ 9 were included in our analysis. Four different groups of young road users were compared to adult trauma data depending on the transportation related injury mechanism. Twenty four thousand three hundred seventy three, datasets were retrieved to compare all subgroups. The mean ISS was 23.3 ± 13.1. The overall mortality rate was 8.61%. In the MVC, the motorbike and the cyclist group, we found young road users having more complex injury patterns with a higher AIS pelvis, AIS head, AIS abdomen and AIS of the extremities and also a lower GCS. Whereas in these three sub-groups the adult trauma group only had a higher AIS thorax. Only in the group of the adult pedestrians we found a higher AIS pelvis, AIS abdomen, AIS thorax, a higher AIS of the extremities and a lower GCS. This study reports on the most common injuries and injury patterns in young trauma patients in comparison to an adult trauma sample. Our analysis show that in contrast to more experienced road users our young collective refers to be a vulnerable trauma group with an increased risk of a high injury severity and high mortality rate. We indicate a striking difference in terms of the region of injury and the mechanism of

Non-hardened roads formed in the production of the Shenfu Coalfield have a unique condition of underlying surface. The road surface is composed of a regolith layer with a certain thickness resulted from long-term rolling and thus, is characterized by weakened anti-scourabilty and anti-erodibility. In contrast, soil layer below the regolith has a higher bulk density and anti-erodibility. The processes of soil erosion on the non-hardened roads exhibit some differences under rainfall condition. The process of sediment transport and the relationship between sediment transport rate and erosion factors at different erosion stages were studied on non-hardened roads with slope degrees ranging from 3° to 12° (3°, 6°, 9°, 12°) by a field experiment under artificial rainfall. Results showed that the first peak of sediment transport on the regolith surface was observed at the sheet erosion stage. Sheet erosion occurred only at 3° slope degree, with an average variation coefficient of 0.07 for sediment transport rate. Rills in every testing began to develop at slope degrees of 6° to 12° about 15 min after runoff initiation. At the sheet erosion stage, the process of sediment transport fluctuated considerably at rainfall intensities of > 1.5 mm · min(-1), but the differences in its variation were little at the three slope degrees, with average variation coefficients of 0.20, 0.19 and 0.16, respectively. Rainfall intensity had a more significant impact on sediment transport rate than slope degree. The process of sediment transport at the rill erosion stage fluctuated, but the fluctuation was obviously smaller than that at the sheet erosion stage, with average variation coefficients of 0.05, 0.09 and 0.10 at the three slope degrees. Many wide and shallow rills evolved at the rill erosion stage. The sediment transport rate could be well predicted by a power function of rainfall intensity and slope degree at the sheet and rill erosion stages. The stable sediment transport

We studied mainstream couples in The Netherlands and Turkey as well as Turkish-Dutch immigrant couples to address cultural factors associated with marital satisfaction. A total of 13 Turkish (mainstream couples living in Turkey), 19 Turkish-Dutch (Turkish immigrant couples living in The Netherlands), and 17 Dutch (mainstream couples living in The Netherlands) married dyads (total of 98 individuals) were independently interviewed about positive and negative characteristics of marriages, determinants of general marital satisfaction and dissatisfaction, spousal communication, marital conflict, and marital roles. Multivariate tests revealed ethnic group differences on all marriage-related domains except the conflict resolution strategies. However, univariate analyses showed differences in few themes within domains; main differences were assessed between the Turkish/Turkish-Dutch (who put more emphasis on children and economical aspects) and Dutch couples (who put more emphasis on behavior, and personality of the spouse, reciprocity, emotional sharing, and psychological roles). Turkish-Dutch couples were more similar to Turkish than to Dutch couples. Results were discussed in light of the socioeconomic development and cultural value theories, which are believed to provide a useful framework for understanding the role of culture in marital satisfaction.

Indirect Energy for Road and Railway Transportation in Sweden; Indirekt energi foer svenska vaeg- och jaernvaegstransporter

Energy Technology Data Exchange (ETDEWEB)

Jonsson, Daniel K.

2005-02-01

Besides energy for propulsion, there are a number of considerable indirect energy categories in the life-cycle of transport systems, e.g. construction and maintenance of infrastructure, and manufacture and service of vehicles. Indirect energy represents 64-66% of the total amount of energy used in the railway sector, while the corresponding share in the road sector is 42-45%. Consequently, decision-making and planning processes regarding transport infrastructure and environmental impacts should also consider indirect energy-use. Two energy case studies have been carried through; the railroad project Botniabanan in the north of Sweden, and the motorway tunnel Soedra Laenken in Stockholm. The result for Botniabanan corresponds with the Swedish railroad average, but Botniabanan contributes to decreased energy use in the transport sector as a whole. The infra structural energy use for Soedra Laenken is considerably higher than the Swedish road average. Soedra Laenken also contributes to an increase of the energy use in the transport sector as a whole.

1985-06-01

The INTERTRAN code was developed by the IAEA in order to provide member states with a simple and rapide method of assessing the risk involved in the transportation of radioactive materials and one which was applicable on a worldwide scale. Before being used, this code must be validated and the CEA thus compared the results obtained with the conventional risk assessment methods used by the CEPN with those derived from INTERTRAN. This paper gives the results of the studies made on the subject of road transportation of uranium hexafluoride in France. The conventional accident risk assessment method gave a figure of 8.84 x 10 -4 deaths/year, whereas INTERTRAN announces 1.78 x 10 -2 . To these figures should be added 3.38 x 10 -2 deaths/year, which is the intrinsic road risk, whatever the goods carried. In relation to conventional estimates, the INTERTRAN forecasts are five times lower for the U risk and twenty times higher for the HF risk. The chemical risk is indeed the most prevalent one in this case. Other comparisons are needed to validate this code

This report is the third of a series dealing with the coordination of ministerial actions in favor of the use of liquefied natural gas (LNG) as fuel in transports. LNG is an important potential substitute to diesel fuel in road transport and would allow significant abatement of nitrogen oxides emissions. Bio-LNG is ten times less polluting than fossil fuel LNG and thus important efforts are to be made in bio-LNG R and D. An important work has been carried out for adapting EU regulations and standards to LNG vehicles and LNG supply developments. This report presents, first, a summary of the report's recommendations and the aim of this coordination study, and, then, treats more thoroughly of the different coordination aspects: 1 - European framework of energy transition in the road freight transport (differences with maritime transport, CO 2 emissions abatement, trucks pollution and fuel quality standards, trucks technical specifications and equipment, fuel taxes in EU countries); 2 - European policy and national actions in favour of LNG development for road transport (LNG as alternate fuel, the Paris agreement, the French national energy plan); 3 - Environmental benefits of LNG in road transport (public health impacts, nitrogen oxides abatement, divergent views and expertise, LNG and CO 2 abatement measures, bio-LNG environmental evaluation; 4 - LNG development actors in road transport and the administrative coordination (professional organizations, public stakeholders, LNG topics information dissemination at the Ministry); 5 - LNG development in road transport at the worldwide, European and national scales; 6 - European regulations and standards allowing trucks LNG fueling and circulation (standard needs, users information, regulation works); 7 - Common rules to define and implement for personnel training; 8 - reflexion on LNG taxation; 9 - support policy for a road transport LNG supply chain (infrastructures, European financing, lessons learnt from maritime

Highlights: ► Energy demand modeling in Thai road transportation sector was developed. ► Such model was used to assess environment impact by ethanol bus technology (ED95). ► Ethanol bus technology (ED95) shows beneficial impacts to Thailand. ► Increase in ethanol demand and decrease in GHG emission in Thailand by ethanol bus. ► Ethanol bus (ED95) has been successfully demonstrated in Thailand. -- Abstract: Over decades, Thailand energy consumption has been concentrated in three main sectors, namely manufacturing, power and transportation. Energy consumption in transportation sector has also been dominated by road transport due to limited coverage by rail and water transportation. Hence, road transport has been a major contributor for greenhouse gas emission in Thailand over recent years. Along with global warming concern throughout the world, Thailand has taken various adaptation and mitigation measures, especially the strong policy push to use carbon–neutral biofuel in transportation sector due to Thailand competitive advantage in agriculture sector. National Renewable Energy Plan (2008–2022) has set challenging targets of 9 and 4.5 million liters/day of ethanol and biodiesel consumption by 2022, respectively. Various blends of ethanol in gasoline (10%, 20% and 85%) and biodiesel in diesel (up to 5%) have been commercially available. However, since current consumption of diesel is twice as much of gasoline, ethanol blend in gasoline would widen the imbalance consumption of gasoline and diesel. The present study however offers an insight into a possibility to use ethanol as diesel substitute. A case study of ethanol bus technology was investigated by recourse to energy demand modeling. Necessary data, such as a number of vehicles (NVs) for various vehicle types, vehicle kilometer of travel (VKT) and fuel economy (FE) were collected, with reasonable assumptions made for those unavailable data, to construct predicative energy demand model.

Because of the low percentage of crashes involving buses and the assumption that public transport improves road safety by reducing vehicular traffic, public interest in bus safety is not as great as that in the safety of other types of vehicles. It is possible that less attention is paid to the significance of crashes involving buses because the safety level of bus systems is considered to be adequate. The purpose of this study was to evaluate the knowledge and perceptions of bus managers with respect to safety issues and the potential effectiveness of various technologies in achieving higher safety standards. Bus managers were asked to give their opinions on safety issues related to drivers (training, skills, performance evaluation and behaviour), vehicles (maintenance and advanced devices) and roads (road and traffic safety issues) in response to a research survey. Kendall's algorithm was used to evaluate the level of concordance. The results showed that the majority of the proposed items were considered to have great potential for improving bus safety. The data indicated that in the experience of the participants, passenger unloading and pedestrians crossing near bus stops are the most dangerous actions with respect to vulnerable users. The final results of the investigation showed that start inhibition, automatic door opening, and the materials and internal architecture of buses were considered the items most strongly related to bus passenger safety. Brake assistance and vehicle monitoring systems were also considered to be very effective. With the exception of driver assistance systems for passenger and pedestrian safety, the perceptions of the importance of other driver assistance systems for vehicle monitoring and bus safety were not unanimous among the bus company managers who participated in this survey. The study results showed that the introduction of new technologies is perceived as an important factor in improving bus safety, but a better understanding

Full Text Available The aim of this article is to investigate the impact of new Turkish commercial code and Turkish accounting standards on accounting education. This study takes advantage of the survey method for gathering information and running the research analysis. For this purpose, questionnaire forms are distributed to university students personally and via the internet.This paper includes significant research questions such as “Are accounting academicians informed and knowledgeable on new Turkish commercial code and Turkish accounting standards?”, “Do accounting academicians integrate new Turkish commercial code and Turkish accounting standards to their lectures?”, “How does modern accounting education methodology and technology coincides with the teaching of new Turkish commercial code and Turkish accounting standards?”, “Do universities offer mandatory and elective courses which cover the new Turkish commercial code and Turkish accounting standards?” and “If such courses are offered, what are their names, percentage in the curriculum and degree of coverage?”Research contributes to the literature in several ways. Firstly, new Turkish commercial code and Turkish accounting standards are current significant topics for the accounting profession. Furthermore, the accounting education provides a basis for the implementations in public and private sector. Besides, one of the intentions of new Turkish commercial code and Turkish accounting standards is to foster transparency. That is definitely a critical concept also in terms of mergers, acquisitions and investments. Stakeholders of today’s business world such as investors, shareholders, entrepreneurs, auditors and government are in need of more standardized global accounting principles Thus, revision and redesigning of accounting educations plays an important role. Emphasized points also clearly prove the necessity and functionality of this research.

Are Chinese Green Transport Policies Effective? A New Perspective from Direct Pollution Rebound Effect, and Empirical Evidence From the Road Transport Sector

Directory of Open Access Journals (Sweden)

Lu-Yi Qiu

2017-03-01

Full Text Available Air pollution has become a serious challenge in China. Emissions from motor vehicles have been found to be one main sources of air pollution. Although the Chinese government has undertaken numerous green policies to mitigate harmful emissions from road transport sector, it is still uncertain for both policy makers and researchers to know whether the policies are effective in the short and long terms. We propose a new concept of “pollution rebound effect” (PRE to estimate the effectiveness of green traffic policies. We estimate direct air PRE as a measure of the effectiveness of the policies of reducing air pollution from the transport sector based on time-series data from the period 1986–2014. We find that the short-term direct air PRE is −0.4105, and the corresponding long-run PRE is −0.246. The negative results indicate that the direct air PRE does not exist in the road passenger transport sector in China, both in the short term and in the long term during the period 1986–2014. This implies that the Chinese green transport policies are effective in terms of harmful emissions reduction in the transport sector. This research, to the best of our knowledge, is the first attempt to quantify the effectiveness of the green transport policies in the transitional period that China is currently undergoing.

Food transport refrigeration - Approaches to reduce energy consumption and environmental impacts of road transport

International Nuclear Information System (INIS)

Tassou, S.A.; De-Lille, G.; Ge, Y.T.

2009-01-01

Food transport refrigeration is a critical link in the food chain not only in terms of maintaining the temperature integrity of the transported products but also its impact on energy consumption and CO 2 emissions. This paper provides a review of (a) current approaches in road food transport refrigeration, (b) estimates of their environmental impacts, and (c) research on the development and application of alternative technologies to vapour compression refrigeration systems that have the potential to reduce the overall energy consumption and environmental impacts. The review and analysis indicate that greenhouse gas emissions from conventional diesel engine driven vapour compression refrigeration systems commonly employed in food transport refrigeration can be as high as 40% of the greenhouse gas emissions from the vehicle's engine. For articulated vehicles over 33 ton, which are responsible for over 80% of refrigerated food transportation in the UK, the reject heat available form the engine is sufficient to drive sorption refrigeration systems and satisfy most of the refrigeration requirements of the vehicle. Other promising technologies that can lead to a reduction in CO 2 emissions are air cycle refrigeration and hybrid systems in which conventional refrigeration technologies are integrated with thermal energy storage. For these systems, however, to effectively compete with diesel driven vapour compression systems, further research and development work is needed to improve their efficiency and reduce their weight

Mobile source emission inventories serve as critical input for atmospheric chemical transport models, which are used to simulate air quality and understand the role of mobile source emissions. The significance of mobile sources is even more important in China because the country has the largest vehicle population in the world, and that population continues to grow rapidly. Estimating emissions from diesel trucks is a critical work in mobile source emission inventories due to the importance and difficulties associated with estimating emissions from diesel trucks. Although diesel trucks are major contributors of nitrogen oxide (NOx) and primary particulate matter smaller than 2.5 μm (PM2.5), there are still more obstacles on the existing estimation of diesel truck emissions compared with that of cars; long-range freight transportation activities are complicated, and much of the basic data remain unclear. Most of existing inventories were based on local registration number. However, according to our research, a large number of trucks are conducting long-distance inter-city or inter province transportation. Instead of the local registration number based approach, a road emission intensity-based (REIB) approach is introduced in this research. To provide efficient data for the REIB approach, 1060 questionnaire responses and approximately 1.7 million valid seconds of onboard GPS monitoring data were collected. Both the questionnaire answers and GPS monitoring results indicated that the driving conditions on different types of road have significant impacts on the emission levels of freight trucks. We present estimated emissions of NOx and primary PM2.5 from diesel freight trucks for China in 2011. Using the REIB approach, the activity level and distribution data are obtained from the questionnaire answers. Emission factors are calculated with the International Vehicle Emission (IVE) model that interpolated local on-board measurement results in China according to the GPS

Selected risk factors of diabetes mellitus among road transport drivers.

Marcinkiewicz, Andrzej; Szosland, Dorota

2010-01-01

Road transport drivers are one of the professional groups whose activities have a strong impact on public safety. In view of the nature of their professional activity, the drivers are at a higher risk of obesity and hypertension, and thus, indirectly, of carbohydrate metabolism disorders such as diabetes mellitus. Medical documentation was a source of data for the reported study. It derived from medical examinations of truck and bus drivers applying for the new category II driving licence or for prolongation of the one they already had. Excessive body weight was recorded in 62.6% of the study population; 45.3% had overweight and 17.4% were diagnosed with obesity. Hypertension was noted in the medical records of 36.7% drivers. The prevalence of abnormal BP values was increasing with age. Overweight was found to be a risk factor for hypertension. Hyperglycaemia was found in 47.5% of the drivers and was also increasing with age. In road transport drivers, the high prevalence of excessive body weight and elevated arterial blood pressure as the risk factors for diabetes indicates a need to undertake multidimensional actions targeted on this particular profession and involving various health care sectors. Prophylactic and detailed pre-placement examinations should be considered, depending on the rate and intensity of the disorders diagnosed. This should be coupled with an introduction of primary and secondary prophylactic activities and monitoring of relevant treatment. A close collaboration with the patient's GP is necessary.

Full Text Available Experiments were carried out with the aim of investigating the modulatory role of ascorbic acid (AA on responses to 8-h road transportation, covering a distance of 260 km at a speed of 40 - 50 km/h, during the harmattan season. Twentynine adult local pigs aged 9 - 12 months served as subjects. Seventeen pigs administered with AA, prior to the transportation, at the dose of 250 mg/kg orally and individually served as experimental animals, and 12 others administered orally with sterile water were used as control animals. The behavioural activities of pigs which included resting (that is, either lying down or standing idle, defaecating, urinating, sniffing, threats of attack (fight, attempts to escape, mounting on one another, hurdling together and routing the floor were monitored with the aid of a video camera without the pigs knowing that they were being observed. Recordings were done based on the number of pigs found performing each activity within 30 min of direct observation, alternated by 30 min of rest and this continued for a period of 4 h. The tape was later watched, analysed and the number of pigs exhibiting each behavioural activity was recorded. Post-transportation, the behavioural activities of standing (94.1 ± 5.8 %, aggressiveness indicated by the percentage of pigs involved in fighting (23.5 ± 6.00 % and attempts to escape (66.67 ± 14.21 % were higher in experimental pigs (P< 0.05 post-transportation than control pigs with the corresponding values of 25.00 ± 3.00 %; 0.00 % and 35.29 ± 11.95 %, respectively. The results showed that road transportation induced considerable behavioural stress resulting in depression of the central nervous system. AA administration pre-transportation reduced the manifestation of stressful behavioural activities in experimental pigs following road transportation. In conclusion, long-term road transportation of pigs during the harmattan season induces behavioural stress, alleviated by AA

Full Text Available Road safety assessment has played a crucial role in the theory and practice of transport management systems. This paper focuses on risk evaluation in the Asian region by exploring the interaction between road safety risk and influencing factors. In the first stage, a data envelopment analysis (DEA method is applied to calculate and rank the road safety risk levels of Asian countries. In the second stage, a structural equation model (SEM with latent variables is applied to analyze the interaction between the road safety risk level and the latent variables, measured by six observed performance indicators, i.e., financial impact, institutional framework, infrastructure and mobility, legislation and policy, vehicular road users, and trauma management. Finally, this paper illustrates the applicability of this DEA-SEM approach for road safety performance analysis.

Economic impact assessments of air pollution-related health effects from a sectoral perspective in China is still deficient. This study evaluates the PM 2.5 pollution-related health impacts of the road transport sector on China's economy at both national and provincial levels in 2030 under various air mitigation technologies scenarios. Health impacts are estimated using an integrated approach that combines the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model, a computable general equilibrium (CGE) model and a health model. Results show that at a national level, the road transport sector leads to 163.64 thousand deaths per year, increases the per capita risk of morbidity by 0.37% and accounts for 1.43 billion Yuan in health care expenditures. We estimate 442.90 billion Yuan of the value of statistical life loss and 2.09 h/capita of work time loss in 2015. Without additional control measures, air pollution related to the transport sector will cause 177.50 thousand deaths in 2030, a 0.40% per capita increase in the risk of morbidity, accounting for 4.12 billion Yuan in health care expenditures, 737.15 billion Yuan of statistical life loss and 2.23 h/capita of work time loss. Based on our model, implementing the most strict control strategy scenario would decrease mortality by 42.14%, morbidity risk by 42.14%, health care expenditures by 41.94%, statistical life loss by 26.22% and hours of work time loss by 42.65%, comparing with the no control measure scenario. In addition, PM 2.5 pollution from the road transport sector will cause 0.68% GDP loss in 2030. At a provincial level, GDP losses in 14 out of 30 provinces far exceed the national rate. Henan (1.20%), Sichuan (1.07%), Chongqing (0.99%), Hubei (0.94%), and Shandong (0.90%) would experience the highest GDP loss in 2030. Implementing control strategies to reduce PM 2.5 pollution in the road transport sector could bring positive benefits in half of the Chinese provinces especially in

Full Text Available The aim of this paper is the analysis of indicators of corporate responsibility in road freight transport, with special emphasis on freight transport and delivery to Fast Moving Consumers Goods (FMCG retailers and final consumer. The main task is to rank the importance of corporate responsibility indicators in freight transport from the perspective of the management of transport companies, as well as management of retail stores. In this context, empirical research was conducted on a sample of 124 managers of transport enterprises and 181 managers of FMCG retailers in Serbia. The results showed that the impact of indicators does not depend on the region, transport company and retail store. The indicators show a statistically significant dependence on FMCG type that is being transported. The conducted analysis and achieved results are important in practice as they show to the management of transport companies which indicators should be developed, so that customers (retailers, and thus the users of final products are satisfied. Disadvantages of the existing research and suggestions for future studies are provided in the paper.

Use of car crashes resulting in fatal and serious injuries to analyze a safe road transport system model and to identify system weaknesses.

Science.gov (United States)

Stigson, Helena; Hill, Julian

2009-10-01

The objective of this study was to evaluate a model for a safe road transport system, based on some safety performance indicators regarding the road user, the vehicle, and the road, by using crashes with fatally and seriously injured car occupants. The study also aimed to evaluate whether the model could be used to identify system weaknesses and components (road user, vehicles, and road) where improvements would yield the highest potential for further reductions in serious injuries. Real-life car crashes with serious injury outcomes (Maximum Abbreviated Injury Scale 2+) were classified according to the vehicle's safety rating by Euro NCAP (European New Car Assessment Programme) and whether the vehicle was fitted with ESC (Electronic Stability Control). For each crash, the road was also classified according to EuroRAP (European Road Assessment Programme) criteria, and human behavior in terms of speeding, seat belt use, and driving under the influence of alcohol/drugs. Each crash was compared and classified according to the model criteria. Crashes where the safety criteria were not met in more than one of the 3 components were reclassified to identify whether all the components were correlated to the injury outcome. In-depth crash injury data collected by the UK On The Spot (OTS) accident investigation project was used in this study. All crashes in the OTS database occurring between 2000 and 2005 with a car occupant with injury rated MAIS2+ were included, for a total of 101 crashes with 120 occupants. It was possible to classify 90 percent of the crashes according to the model. Eighty-six percent of the occupants were injured when more than one of the 3 components were noncompliant with the safety criteria. These cases were reclassified to identify whether all of the components were correlated to the injury outcome. In 39 of the total 108 cases, at least two components were still seen to interact. The remaining cases were only related to one of the safety criteria

It is widely accepted that transport is stressful for horses, but only a few studies are available involving horses that are transported regularly and are accustomed to transport. We determined salivary cortisol immunoreactivity (IR), fecal cortisol metabolites, beat-to-beat (RR) interval, and heart rate variability (HRV) in transport-experienced horses (N=7) in response to a 2-d outbound road transport over 1370 km and 2-d return transport 8 d later. Salivary cortisol IR was low until 60 min before transport but had increased (PHRV variable standard deviation 2 (SD2) occurred (PHRV, which is indicative of stress. The degree of these changes tended to be most pronounced on the first day of both outbound and return transport. Copyright 2009 Elsevier Inc. All rights reserved.

Yang Jie; Li Fengying; Zhou Jingbo; Zhang Ling; Huang Lei; Bi Jun

2010-01-01

A study of 322 accidents that occurred during the road transport of hazardous materials (hazmat) in China from 2000 to 2008 was carried out. The results showed an increase in the frequency of accidents from 2000 to 2007 and a decline in 2008. More than 63% of the accidents occurred in the eastern coastal areas, 25.5% in the central inland areas, and only 10.9% in the western remote areas. The most frequent types of accident were releases (84.5%), followed by gas clouds (13.0%), fires (10.2%), no substance released due to timely measures (9.9%), and explosions (5.9%). The spatial distribution, the causes and consequences of the accidents related to the population (e.g., number of people killed, injured, evacuated, or poisoned), and environment elements were analyzed. Finally, conclusions are drawn concerning the need to improve certain safety measures in the road transport of hazmat in China.

In spring 1990, the Federal German Minister for Education, Science, Research and Technology (BMBF) commissioned the team from the Federal Institute for Materials Research and Testing (BAM), DEKRA, Daimler-Benz, the Federal Road Research Institute (BASt) with the University of Cologne, Ellinghaus and TUeV Rheinland (project leader) to perform the research project `THESEUS` (the acronym THESEUS comes from the German `Tankfahrzeuge mit hoechst erreichbarer Sicherheit durch experimentelle Unfallsimulation`, which translates as `achieving maximum possible road transport tanker safety by means of experimental accident simulation`). Arting from an analysis of road transport tanker accidents, crash tests and overturn tests were performed and supplemented by investigations of road transport tanker components and accompanying complex calculations of the failure processes. Parallel to this, the static side-tilt stability of road transport tankers was determined on a tilting test platform. The causes of and constructive possibilities for avoiding overturning, which is the most common cause of accidents in which hazardous materials escape, wewre analysed in dynamic driving tests with supplementary computer simulation. Various measures for improving the safety of road transport tankers were determined and subjected to a cost-benefit analysis. (orig.)

Full Text Available The development of tourism in Thailand relies on the development of appropriate infrastructure. Road access is the key infrastructure issue for tourist destinations throughout Thailand. Each year Thailand has welcomed over 15 million travelers, accounted approximately 7% of GDP. To support tourist activities, variety types of transportation modes have designed. However, road transportation is one of the most effective modes that connect most places together. Beside high-standard vehicles, road is another mechanism that derive comfort and safety of travelling. For this reason, Motorway networks were initiated and constructed to support high speed traffic with high safety and standard. Motorway route 7 is one of major motorway networks that lies between major cities and tourist landmarks. To raise the road standard could be the key to support tourist industry and economic growth. The road developments may not be precise and accurate without knowing the needs from road users’. Therefore, a questionnaire is developed and distributed to 890 randomly selected road users along Motorway route 7. Factor analysis and t-test are employed to analyze the factors affecting road users’ satisfaction and to compare the satisfaction level between both inbound and outbound travelers.

Full Text Available To investigate the injury characteristics and mortality of patients transported by emergency medical services (EMS and hospitalized for trauma following a road traffic crash, data obtained from the Trauma Registry System were retrospectively reviewed for trauma admissions between 1 January 2009 and 31 December 2013 in a Level I trauma center. Of 16,548 registered patients, 3978 and 1440 patients injured in road traffic crashes were transported to the emergency department by EMS and non-EMS, respectively. Patients transported by EMS had lower Glasgow coma scale (GCS scores and worse hemodynamic measures. Compared to patients transported by non-EMS, more patients transported by EMS required procedures (intubation, chest tube insertion, and blood transfusion at the emergency department. They also sustained a higher injury severity, as measured by the injury severity score (ISS and the new injury severity score (NISS. Lastly, in-hospital mortality was higher among the EMS than the non-EMS group (1.8% vs. 0.3%, respectively; p < 0.001. However, we found no statistically significant difference in the adjusted odds ratio (AOR for mortality among patients transported by EMS after adjustment for ISS (AOR 4.9, 95% CI 0.33–2.26, indicating that the higher incidence of mortality was likely attributed to the patients’ higher injury severity. In addition, after propensity score matching, logistic regression of 58 well-matched pairs did not show a significant influence of transportation by EMS on mortality (OR: 0.578, 95% CI: 0.132–2.541 p = 0.468.

Understanding and Improving Arterial Roads to Support Public Health and Transportation Goals.

Science.gov (United States)

McAndrews, Carolyn; Pollack, Keshia M; Berrigan, David; Dannenberg, Andrew L; Christopher, Ed J

2017-08-01

Arterials are types of roads designed to carry high volumes of motorized traffic. They are an integral part of transportation systems worldwide and exposure to them is ubiquitous, especially in urban areas. Arterials provide access to diverse commercial and cultural resources, which can positively influence community health by supporting social cohesion as well as economic and cultural opportunities. They can negatively influence health via safety issues, noise, air pollution, and lack of economic development. The aims of public health and transportation partially overlap; efforts to improve arterials can meet goals of both professions. Two trends in arterial design show promise. First, transportation professionals increasingly define the performance of arterials via metrics accounting for pedestrians, cyclists, transit riders, and nearby residents in addition to motor vehicle users. Second, applying traffic engineering and design can generate safety, air quality, and livability benefits, but we need evidence to support these interventions. We describe the importance of arterials (including exposures, health behaviors, effects on equity, and resulting health outcomes) and make the case for public health collaborations with the transportation sector.

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

Modeling hydrology and reactive transport in roads: The effect of cracks, the edge, and contaminant properties

International Nuclear Information System (INIS)

Apul, Defne S.; Gardner, Kevin H.; Eighmy, T. Taylor

2007-01-01

The goal of this research was to provide a tool for regulators to evaluate the groundwater contamination from the use of virgin and secondary materials in road construction. A finite element model, HYDRUS2D, was used to evaluate generic scenarios for secondary material use in base layers. Use of generic model results for particular applications was demonstrated through a steel slag example. The hydrology and reactive transport of contaminants were modeled in a two-dimensional cross section of a road. Model simulations showed that in an intact pavement, lateral velocities from the edge towards the centerline may transport contaminants in the base layer. The dominant transport mechanisms are advection closer to the edge and diffusion closer to the centerline. A shoulder joint in the pavement allows 0.03 to 0.45 m 3 /day of infiltration per meter of joint length as a function of the base and subgrade hydrology and the rain intensity. Scenario simulations showed that salts in the base layer of pavements are depleted by 99% in the first 20 years, whereas the metals may not reach the groundwater in 20 years at any significant concentrations if the pavement is built on adsorbing soils

2017-10-01

The article considers one of the topical problems of road safety management at the federal level - the problem of the heterogeneity of road traffic accident rate in Russian cities. The article analyzes actual statistical data on road traffic accident rate in the administrative centers of Russia. The histograms of the distribution of the values of two most important road accidents characteristics - Social Risk HR and Severity Rate of Road Accidents - formed in 2016 in administrative centers of Russia are presented. On the basis of the regression model of the statistical connection between Severity Rate of Road Accidents and Social Risk HR, a classification of the Russian cities based on the level of actual road traffic accident rate was developed. On the basis of this classification a differentiated system of priority methods for organizing the safe functioning of transport systems in the cities of Russia is proposed.

Atmospheric emissions from road transportation in India

International Nuclear Information System (INIS)

Baidya, S.; Borken-Kleefeld, J.

2009-01-01

India has become one of the biggest emitters of atmospheric pollutants from the road transportation sector globally. Here we present an up-to-date inventory of the exhaust emissions of ten species. This inventory has been calculated bottom-up from the vehicle mileage, differentiating by seven vehicle categories, four age/technology layers and three fuel types each, for the seven biggest cities as well as for the whole nation. The age composition of the rolling fleet has been carefully modelled, deducting about one quarter of vehicles still registered but actually out-of-service. The vehicle mileage is calibrated to the national fuel consumption which is essential to limit uncertainties. Sensitivity analyses reveal the primary impact of the emission factors and the secondary influence of vehicle mileage and stock composition on total emissions. Emission estimates since 1980 are reviewed and qualified. A more comprehensive inspection and maintenance is essential to limit pollutant emissions; this must properly include commercial vehicles. They are also the most important vehicle category to address when fuel consumption and CO 2 emissions shall be contained. (author)

Road Infrastructure Safety Management in Poland

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

This report explains the parts of the Danish inventories related to road transport and other mobile sources. Emission results for CO 2 , CH 4 , N 2 O, SO 2 , NO X , NMVOC, CO, particulate matter (PM), heavy metals, dioxins and PAH are shown from 1985 to 2004. In this period the fuel use and CO 2 emissions for road transport have increased by 48%. The emission decreases for PM (exhaust only), CO, NO X and NMVOC are 35, 58, 34 and 66% respectively, due to the introduction of vehicles complying with gradually stricter emission standards. A N 2 O emission increase of 301% is related to the high emissions from gasoline catalyst cars. For other mobile sources the fuel use and CO 2 emissions have decreased by 15% from 1985 to 2004. The PM, NO x and NMVOC emission declines are 46, 14 and 10%, respectively. For SO 2 the emission drop is 74% from 1985 to 2004, due to gradually lower fuel sulphur contents. For CO the 1985 and 2004 emissions are the same. Uncertainties for the emissions and trends have been estimated. (au)

Seasonal Drivers of Dissolved Metal Transport During Infiltration of Road Runoff in an Urban Roadside Environment

Science.gov (United States)

Mullins, A.; Bain, D.

2017-12-01

Infiltration-based green infrastructure (GI) is being increasingly applied in urban areas, systems characterized by substantial legacy contamination and complicated hydrology. However, it is not clear how the application of green infrastructure changes the geochemistry of urban roadside environments. Most current research on GI focuses on small sets of chemical parameters (e.g. road salt, nitrogen and phosphorous species) over relatively short time periods, limiting comprehensive understanding of geochemical function. This work measures changes in groundwater infiltration rate and dissolved metal concentrations in two infiltration trenches in Pittsburgh, PA to evaluate function and measure dissolved metal transport from the system over time. Two distinct geochemical regimes seem to be driven by seasonality: road de-icer exchange and microbial driven summer reducing conditions. Interactions between these geochemical regimes and variability in infiltration rate control the flux of different metals, varying with metal chemistry. These findings suggest the adoption of infiltration based green infrastructure will likely create complicated patterns of legacy contamination transport to downstream receptors.

2001-08-01

This article describes the state of the automobile industry and urban road transportation management in China. It reviews how the automobile industry is evolving to respond to challenges in economic development, environmental regulations, and technological change. The dynamics and barriers resulting from technological change of the automobile in response to reduction of exhaust emissions and energy-efficiency improvement are analyzed. It is argued that consideration of externality costs should be integrated in automobile industrial policy making and transport management. This paper questions the current government policy of encouraging private car ownership, and suggests that improvement in public transportation systems and stronger emissions control would be relevant to China's drive toward sustainable transportation development.

Road transportation has contributed to increased emissions of conventional air pollutants and, consequently, to the increase in problems associated with the environment and human health, depending on the type of pollutant and the concentration of it. To support the development of public policies aimed to decrease total tonnes of emissions, we used a bottom-up approach to estimate the amount of air pollutants, such as carbon monoxide (CO), total hydrocarbons (THC), nitrogen oxides (NO x ), particulate matter (PM), and aldehydes (RCHO), that are emitted by road transportation in the state of Rio de Janeiro (RJ) from 1980 to 2010. The results from 2010 show that cars are responsible for 55% of CO emissions, 61% of THC emissions, and 93% of RCHO emissions. Due to the use of hydrated ethanol and compressed natural gas (CNG) instead of petroleum based fuels during the period analyzed, 1,760,370 t of air pollutant emissions were avoided. Compared to Brazil, in 2010, RJ had a quantity of emissions per vehicle from 12% (CO) to 59% (PM) smaller than the national average. As strategies to reduce air pollutant emissions, we consider reducing the intensity of use, with a proportional reduction in emissions, and increased the use of biodiesel. - Highlights: ► We estimate road transportation emissions for Rio de Janeiro from 1980 to 2010. ► C gasoline was most responsible for CO (74%) and diesel for PM (91%). ► Emissions/vehicle for Rio de Janeiro are (12% to 59%) smaller than Brazilian. ► 1,760,370 t of emissions was avoided using non-petroleum-based fuels. ► Strategies to reduce the emissions of these air pollutants were proposed.

Menossi, C.A.; Segado, R.; Reyes, R.

1983-01-01

A probability model for the evaluation of the individual radiological risk resulting from road transportation of tritiated water in 200-liter drums is presented. In order to evaluate such risk, an evaluation must be made of the probability for an individual to be involved in the consequences of a radiological transport accident, to incur a given dose and to suffer deleterious effects resulting from the dose incurred. With the purpose of quantifying the importance of accidents, a severity level classification was adopted as a function of the fraction of liquid volume spilled as a result of the accident. Considering the above-mentioned severity classification and the transported volume, the volume and the spill area are implied, while the soil characteristics are taken into account. By evaluating the spill characteristics, the average meteorological conditions in the area under analysis and the activity concentration of the transported liquid, the activity concentration values for tritium in air may be estimated, thus allowing calculation of the effective dose equivalent to be incurred by the individual who is most exposed to the consequences of an associated event. As a result of the summarized analysis above, a value of the individual risk per unit of activity concentration is obtained for tritium and for a given volume of transported liquid. 8 references

2014-06-01

The article aims to examine the relationship between road transport and macro economy, especially the use of fossil energy in transport sector. Nowadays environmental pollution is a key issue on the EU level as well as in Hungary. Lots of effort have been already done in order to decrease emissions in road transport, but a lot more need to be done. The article aims to prove that the only possible solution is technological innovation in order to reach emission reduction target without decline of the GDP. The basic idea is to ensure sustainable development, to decrease environmental pollution in road transport without harming the economy. In the EU and in Hungary road vehicles are powered by fossil fuelled internal combustion engines. This paper aims to analyse the role of the fossil fuel-based road transport sector within the economy with the usage of constant elasticity substitution (CES) production functions. Authors have built CES production function for Hungary. Parameters were calculated based on the validated model.

Full Text Available The functions of the scientific texts under the informative text type are referring to the results of a research, reinterpreting certain research results, or reaching original results. When literature reviewed, it is observed that although the studies for creating scientific text have increased recently, it seems that the desired outcome is not achieved. In addition to teaching Turkish as a mother tongue, teaching it as a foreign language has also started to gain importance. For this reason, it is necessary to carry out such studies in order to increase the productivity in the field of teaching Turkish to foreigners. The aim of the study is to determine the orientations related to the rhetorical arrangement of the scientific texts on teaching of Turkish as a foreign language, which are included in the textbooks of the International Training and Education of Turkish Language Congresses as a full text and to evaluate these texts in terms of their specific functions. Findings and determinations revealed in the study are based on a corpus comprised of a total of 64 texts included in proceedings books, written in Turkish and related to teaching Turkish to foreigners. The study is structured by qualitative research method. The data were obtained by qualitative data collection techniques through document scanning and were examined within the framework of the scientific text criteria specified by Huber and Uzun (2001. Two out of 64 articles in the sample of the study revealed that none of the expected functional steps in the introduction, main and final sections were found. No work has been found that covers all of the functional steps in the introduction, main and final sections.

Baptista, Patrícia C.; Silva, Carla M.; Farias, Tiago L.; Heywood, John B.

2012-01-01

This study presents a methodology to develop scenarios of evolution from 2010 to 2050, for energy consumption and emissions (CO 2 , HC, CO, NO x , PM) of the road transportation sector (light-duty and heavy-duty vehicles). The methodology is applied to Portugal and results are analyzed in a life-cycle perspective. A BAU trend and 5 additional scenarios are explored: Policy-based (Portuguese political targets considered); Liquid fuels-based (dependency on liquid fuels and no deployment of alternative refueling infrastructure); Diversified (introduction of a wide diversity of alternative vehicle technology/energy sources); Electricity vision (deployment of a wide spread electricity recharging infrastructure); Hydrogen pathway (a broad hydrogen refueling infrastructure is deployed). Total life-cycle energy consumption could decrease between 2 and 66% in 2050 relatively to 2010, while CO 2 emissions will decrease between 7 and 73% in 2050 relatively to 2010. In 2050 the BAU scenario remains 30% above the 1990 level for energy consumption and CO 2 emissions; the other considered scenarios lead to 4 to 29% reductions for energy consumption and 10 to 33% for CO 2 emissions in 2050 compared to the BAU. Therefore, alternative vehicle technologies are required in the long-term, but changes in taxation and alternative transportation modes policies are crucial for achieving short-term impacts. - Highlight: ► Assess future energy consumption and emissions scenarios for road transportation. ► LCA energy consumption could decrease 2 to 66% in 2050 relatively to 2010. ► Alternative vehicle technologies can help to lower the BAU scenario impacts. ► Different deployments of alternative technologies can lead to similar impacts.

In France, road transport is the main source of pollutant emissions in urban areas despite a fall in emissions of certain pollutants, recently achieved following significant technological progress and new legislation adopted. In addition, CO 2 emissions from motor vehicles continue to rise, accounting for about 40 % of net CO 2 emissions in France. These trends are mainly due to consumer behaviour and the use of motor vehicles. The sharp increase in passenger and freight traffic and an increase in the distances covered have negative impacts on the environment. In light of this situation, new technologies appear to be an inadequate solution to reverse emission trends. (A.L.B.)

An object of this study is the old Akiha road located along the southern parts of the Akaishi Mountains in Sizuoka Prefecture. The old Akiha road between Hamamatsu city in Enshu and Iida city in Shinshu had been utilized by people for the purposes of making a pilgrimage, megalithic faith, transporting obsidian since the primitive age, practicing the mountaineering asceticism, operating the military activities in the warlike age, transporting salt from coastal area to mountainous area and so on. Through the investigation of literature, site reconnaissance and hearing, the formation process and the historical functions of the old Akiha road were studied, including the situation in medieval times or before. As the results, it was elucidated that the oldest road between two cities had located over the Hyoukoshi Pass, the road routes had the lowering trend from mountainside to riverside, and the historical functions of old Akiha road were the passage for transportation of various kinds of goods and human being, faith and culture.

The aim of the study is to define the probability of accident that can be applied to a packaging for plutonium oxide transport. The analysis is designed essentially for packagings of few tons with impact resistance corresponding to a speed of 10 m/s but can be used for packagings with a resistance corresponding to IAEA tests. This work is based on analysis and processing of 2 accident files: one on road accidents, the other on air accidents. Computer codes are developed, from one hand, to obtain stress indicator distribution by Monte Carlo methods and on the other hand to link these distributions to itinerary parameters. Previous similar studies are examined and compared to figures obtained here and explained as far as possible [fr

Every year many traffic accidents with fatal outcomes occur in our Country. According to the recent indications of the European Agency for Safety and Health at Work, the Piedmont region has financed the plan: Prevention of road accidents in the road haulage field. The aims of the plan are to stimulate transport companies to the target of road safety and to improve and enforce sanitary surveillance, in order to improve the safety on road haulage and to prevent traffic injuries. the plan foresees, over a period of two years, a few encounters with all the interested parties (companies, police forces, labour unions etc). During those encounters we have to give a questionnaire for evaluating the companies' knowledge about the problem and we have to choose a common plan with the aim of improving road safety. The Piedmont regional plan recalls the need to increase the attention to numerous and diversified hazards for safety on road haulage. It also imposes the choice of measures that include: risk assessment, health education, technical and environmental prevention, sanitary surveillance and clinical interventions (diagnosis and rehabilitation of occupational accidents).

This developmental effort clearly shows that a Road Transportable Analytical Laboratory System is a worthwhile and achievable goal. The RTAL is designed to fully analyze (radioanalytes, and organic and inorganic chemical analytes) 20 samples per day at the highest levels of quality assurance and quality control. It dramatically reduces the turnaround time for environmental sample analysis from 45 days (at a central commercial laboratory) to 1 day. At the same time each RTAL system will save the DOE over $12 million per year in sample analysis costs compared to the costs at a central commercial laboratory. If RTAL systems were used at the eight largest DOE facilities (at Hanford, Savannah River, Fernald, Oak Ridge, Idaho, Rocky Flats, Los Alamos, and the Nevada Test Site), the annual savings would be $96,589,000. The DOE`s internal study of sample analysis needs projects 130,000 environmental samples requiring analysis in FY 1994, clearly supporting the need for the RTAL system. The cost and time savings achievable with the RTAL system will accelerate and improve the efficiency of cleanup and remediation operations throughout the DOE complex.

The prospects for limiting emissions from road transport: a case study for the Middle Odra and Poland

Science.gov (United States)

Dzikuć, Maciej; Dzikuć, Maria

2018-02-01

The article presents selected aspects related to emissions that arise during road transport. These impurities are an important component of low emission, which is generated at a height of up to 40 m from the ground level. Low emission in the Middle Odra Region and throughout Poland is a serious problem. Low emission has a significant share in total emissions in Poland, where the air is one of the worst in the EU. The problem of low emission concerns not only highly urbanized areas, but also places where the industry is less developed and the number of inhabitants falling on average per square kilometre is less than in the rest of Poland. An example of such an area is the Middle Odra, which additionally features the highest forest cover in the country (more than 50%). The paper highlights the main causes of road transport emissions and points out the need to take action that can significantly help reduce this phenomenon.

This document reports on a study undertaken at the request of the United Grain Growers regarding government fuel tax revenue and the relationship to expenditures on roads. The account of fuel tax revenues was compiled from data collected from several different sources, as was the case for the road expenditures at the federal, provincial, local and modal levels. The emphasis was placed on the effects of fuel taxes on grain handling and transportation in the Prairie provinces. The authors presented fuel tax revenues broken down by mode of transportation and by province. The document was divided as follows: the first part was the introduction with the second part dealing with fuel tax rates and policies. In the third part, the topic of fuel tax and road related revenues was examined. Part four discussed road expenditures. The authors concluded that Transport Canada has traditionally represented the most important federal link to provincial highway infrastructure. It was noted that 4.2 billion dollars in road fuel taxes were collected by the federal government in 1998/1999, and of that amount, 198 million dollars, or 4.7 per cent, was reinvested in the National Highway System in programs managed by Transport Canada. Nearly one dollar on roads is spent by provincial governments on a Prairie-wide basis for every dollar collected in road fuel taxes, with Alberta spending the most and Saskatchewan spending the least. 15 tabs

To compare the Dutch governmental efforts and developments in the field of electric road transport, the Ministry of Economic Affairs, Agriculture and Innovation has asked ECN Policy Studies and NL Agency to conduct an international assessment on electric mobility. The countries that have been considered are: Austria, Belgium, Denmark, France, Germany, the Netherlands, Norway, Portugal, Spain, UK, China, USA and South Korea. The Netherlands has a high ambition level with regard to the number of electric vehicles and is one of the leaders as for the envisaged number of charging points. In the field of R and D, Germany, South Korea and China take the lead, followed by France, the UK, the USA and Austria. However, the assessment has only looked at specific funds for electric mobility, and has not looked at general R and D and innovation funds. The Netherlands has several electro-mobility field tests, but is not leading in number. Norway and Austria are leading countries when it comes to implementation of public charging infrastructure.

Sustainable road safety: a new (?) neighbourhood road pattern that saves VRU lives.

Science.gov (United States)

Wei, Vicky Feng; Lovegrove, Gord

2012-01-01

Both the UN (2007) and World Health Organizations (2004) have declared the enormous social and economic burden imposed on society by injuries due to road collisions as a major global problem. While the road safety problem is not new, this prominent global declaration sends an important signal of frustration regarding progress to date on reducing road collisions. It is clear that governments, communities, businesses and the public must discover ways of reducing this burden, especially as it relates to vulnerable road users (VRUs), typically meaning pedestrian and bicyclist road users. Recent comparisons of global VRU collisions statistics suggest that, in addition to mixed land use density, the layout of neighbourhood roads plays a vital role in the encouragement of walkable, safe and quiet, yet accessible and sustainable communities. The purpose of this paper was to: The Dutch Sustainable Road Safety (SRS) Program has produced a number of innovative land use and transportation initiatives for vehicular road users as well as non-vehicular VRUs. Following from the Dutch initiatives, these new 3-way offset, and fused grid neighbourhood patterns appear to not only have positive effects in encouraging mode split (i.e. increasing walking and bicycling, and transit), slowing traffic, and reducing energy consumption and GHG emissions; but also, to hold potential to improve road safety. To test the road safety hypothesis, UBCO researchers evaluated the level of road safety relative to five neighbourhood patterns - grid, culs-de-sac, and Dutch Sustainable Road Safety (SRS) (or limited access), 3-way offset, and fused grid networks. Analysis using standard transportation planning methodology revealed that they would maintain both mobility and accessibility. Analysis using standard road safety analysis methodology further revealed that these 3-way offset, and fused grid patterns would significantly improve road safety levels by as much as 60% compared to prevalent patterns (i

Emissions of CO2 from road freight transport in London: Trends and policies for long run reductions

International Nuclear Information System (INIS)

Zanni, Alberto M.; Bristow, Abigail L.

2010-01-01

Freight transport has been receiving increasing attention in both literature and practice following the growing recognition of its importance in urban transport planning. This paper analyses historical and projected road freight CO 2 emissions in the city of London and explores the potential mitigation effect of a set of freight transport policies and logistics solutions. Findings indicate a range of policies with potential to reduce emissions in the period up to 2050. However, this reduction would appear to only be capable of partly counterbalancing the projected increase in freight traffic. More profound behavioural measures therefore appear to be necessary for London's CO 2 emissions reduction targets to be met.

2017-12-08

For off-road mobility, some manual or power assisted devices were conceived to be self-driven by paraplegics while for tetraplegics non power-assisted devices were conceived. These devices require one or more conductors who are subjected to a high physical demand thus potentially creating: precarious safety condition for the user an elevated physical demand of conductors could reduce the care and the attention to give to the user; the time of the outdoor adventure experience of the user could be limited. To address these issues, an innovative user-centered power assisted off-road wheelchair for the transportation of tetraplegics along mountain trails was developed. The device, structured like a trike, is driven by two healthy conductors; the user is placed in the middle of the frame. A movable seat provides for the transfer from the standard to the off-road wheelchair. An electrical motor, powered by a battery pack, provides for the actuation. All the design and prototype aspects, the control system and experimental tests are detailed. The prototype satisfies mechanical, safety and duration requirements. No physical demand while using the device and for the transfer of the user to the device was identified. Fun and engaging tests were carried out and all the participants were involved. Implications for Rehabilitation The device has the potential to enhance the quality of life of tetraplegics in terms of new life experiences. The device revealed the real possibility of a full recreational experience, an enhanced participation and a better social integration of tetraplegics.

Assessment of on-road transportation demand and CO2 emissions for determination of air quality impacts from the Megacity of São Paulo

Science.gov (United States)

Perez-Martinez, P. J.; Miranda, R. M.; Andrade, M. D. F.

2017-12-01

In this manuscript we assess the capability of using mobility surveys and a high-scale assignment and emission model to study climate change and air quality impacts related to on-road transportation in the Megacity of São Paulo (MSP). Initially, we estimate CO2 emissions of light and heavy vehicles (LVs and HVs) at a spatial scale of 500m and temporal scale of an hour, using transport demand modeling. The estimates are based on origin and destination trip pairs and the height of the planetary boundary layer (PBL). These estimates, performed for the years 2007 and 2012, depend also on intermediate variables as dilution rates (D) and surface particulate-matter concentrations (PM). Secondly, we assess the changes in CO2 vehicle emissions from the MRSP over the period 2007-2012 (4% year-1). Consequently, CO2 emission inventories merge trip-based surveys, traffic assignments and road network database with air pollution monitoring data. Despite the difference of the methodologies, we use a road link bottom up vehicle activity based approach, the assessed emissions agree with the State's Emission Inventory. This paper shows that the CO2 emissions from LDVs and HDVs in the MSP in 2007 and 2012 were 8,477 and 10,075 tCeq day-1 (58% LVs and 42% HVs), respectively. CO2 emissions from vehicles show spatial patterns consistent with passenger and freight transport trips and road network assignments. Temporal profiles (diurnal, weekly and monthly) were estimated using traffic counts and congestion surrogates. The profiles were compared with average road-site (Western of MSP) and background (Jaraguá Peak) CO2 measurements available for 2014. On-road measurements showed one peak associated to the morning peak hour of vehicles (437±45 ppm) and another night peak (435±49 ppm) related to the low PBL (313 m) and D (329 m2 h-1). From on-road measurements, background values (414±2 ppm) were subtracted to estimate excess CO2 (12±8 ppm) directly attributed to vehicles. The inventory

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

Carbon Nanomaterials for Road Construction

Full Text Available The requirement of developing and modernizing the roads in Russia and in the Volgograd region in particular, is based on need of expanding the directions of scientific research on road and transport complexes. They have to be aimed at the development of the theory of transport streams, traffic safety increase, and, first of all, at the application of original methods of road development and modernization, introduction of modern technologies and road-building materials.On the basis of the analysis of the plans for transportation sphere development in the Volgograd region assuming the need to apply the new technologies allowing to create qualitative paving, the authors propose the technology of creating a heavy-duty paving with the use of carbon nanomaterial. The knowledge on strengthening the characteristics of carbon nanotubes is a unique material for nanotechnology development which allowed to assume the analysis of general information about asphalt concrete. The analysis showed that carbon nanotubes can be used for improvement of operational characteristics of asphalt concrete, and it is possible to carry out additives of nanotubes in hot as well as in cold bitumen. The article contains the basic principles of creation of the new road material received by means of bitumen reinforcing by carbon nanotubes. The structures received by the offered technique binding on the basis of the bitumens modified by carbon nanomaterial can be used for coverings and bases on highways of all categories in all road and climatic zones of Russia. The technical result consists in increasing the durability and elasticity of the received asphalt covering, and also the increase of water resistance, heat resistance and frost resistance, the expansion of temperature range of its laying in the field of negative temperatures.

Road network safety evaluation using Bayesian hierarchical joint model.

Science.gov (United States)

Wang, Jie; Huang, Helai

2016-05-01

Safety and efficiency are commonly regarded as two significant performance indicators of transportation systems. In practice, road network planning has focused on road capacity and transport efficiency whereas the safety level of a road network has received little attention in the planning stage. This study develops a Bayesian hierarchical joint model for road network safety evaluation to help planners take traffic safety into account when planning a road network. The proposed model establishes relationships between road network risk and micro-level variables related to road entities and traffic volume, as well as socioeconomic, trip generation and network density variables at macro level which are generally used for long term transportation plans. In addition, network spatial correlation between intersections and their connected road segments is also considered in the model. A road network is elaborately selected in order to compare the proposed hierarchical joint model with a previous joint model and a negative binomial model. According to the results of the model comparison, the hierarchical joint model outperforms the joint model and negative binomial model in terms of the goodness-of-fit and predictive performance, which indicates the reasonableness of considering the hierarchical data structure in crash prediction and analysis. Moreover, both random effects at the TAZ level and the spatial correlation between intersections and their adjacent segments are found to be significant, supporting the employment of the hierarchical joint model as an alternative in road-network-level safety modeling as well.

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.

Full Text Available This study was carried out to examine access to rural road infrastructure and its effects on smallholder farmers’ agricultural productivity in Horro Guduru Wollega Zone, Western Ethiopia. A three stage random sampling technique was employed to select 500 farming households in the study area and data was collected on their socio-economic and farm specific characteristics. The collected data was analyzed using descriptive statistics and stepwise multiple regression analysis. The result of multiple regression model used revealed that distance to major market is important in predicting agricultural productivity of smallholder farmers at 5% levels of probability in Abe Dongoro, Amuru and Hababo Guduru districts. Ownership of intermediate means of transport was also found to influence agricultural productivity in Horro, Amuru and Hababo Guduru districts (p = 0.05. Further analysis of the regression model showed a significant negative correlation between distance to nearest all weather roads and distance to zonal head quarter on one hand and agricultural productivity on the other hand in Abe Dongoro, Hababo Guduru and Amuru districts. Rural kebeles of Abe Dongoro and Amuru districts which has vast agricultural potential were found to be the most inaccessible in Horro Guduru Wollega Zone. It is therefore suggested that interventions in the transport sector should include provision of rural roads as well as measures that will help improve vehicle supply in rural areas. An attempt has to be done also to increase the use of intermediate means of transport to ease agricultural inputs and outputs mobility and farm access.

Full Text Available The work, result of a research carried out in collaboration with the Chamber of Commerce of Lucca, aims to implement a tool for the evaluation of positive and negative effects arising by the “widening” or “new construction” of road transport infrastructures in the territory. In particular, with respect to the impacts generated by the project actions relating to the construction or widening of roads, the research has produced several sensitivity maps of the studied area and a graphical interface, accessible on the Internet and user friendly, allowing the synthetic evaluation of the impacts and the comparison of different scenarios The implemented methodology, through the use of advanced tools for data management and processing and for impacts quantification and assessment, has allowed us to define a very detailed database related to all components of study area, both natural and anthropic, and to build a "synthetic sensitivity index", obtained from the combination of thematic information about each component and from the relationships that involve each others. It’s therefore to consider an indispensable support tool for planners and evaluators (eg. SEA procedures, but also for others users (eg organizations representing businesses, consumer associations, etc.. In fact it allows to acquire a deep knowledge of the area (environmental and economic resources, to verify the sensitivity of each part of the area with respect to a series of project actions concerning both the construction of new roads that the widening of the existing ones and finally to evaluate different localization scenarios for the same type of project or different impact scenarios for the same localization.

Road safety and trade and industry.

Trade and industry mostly experience the negative consequences of crashes, but sometimes the consequences are positive. The negative consequences of road traffic crashes include loss of personnel and damage to vehicles. Some other industries, such as damage repair companies, on the other hand, derive income from road crashes. Trade and industry can also be of importance for road safety. Particularly the transport sector, the car industry and insurers take several initiatives which for example...

Due to the sheer size and capacity of the tanker and the properties of cargo transported in the tank, hazmat tanker accidents are more disastrous than other types of vehicle accidents. The aim of this study was to provide a current survey on the situation of accidents involving tankers transporting hazardous materials in China. Detailed descriptions of 708 tanker accidents associated with hazmat transportation in China from 2004 to 2011 were analyzed to identify causes, location, types, time of occurrence, hazard class for materials involved, consequences, and the corresponding probability. Hazmat tanker accidents mainly occurred in eastern (38.1%) and southwest China (12.3%). The most frequent hazmat tanker accidents involved classes 2, 3, and 8. The predominant accident types were rollover (29.10%), run-off-the-road (16.67%), and rear-end collisions (13.28%), with a high likelihood of a large spill occurring. About 55.93% of the accidents occurred on freeways and class 1 roads, with the spill percentage reaching 75.00% and the proportion of spills that occurred in the total accidents amounting to 77.82%, of which 61.72% are considered large spills. The month with the highest accident probability was July (12.29%), and most crashes occurred during the early morning (4:00-6:00 a.m.) and midday (10:00 a.m.-12:00 p.m.) hours, 19.63% versus 16.10%. Human-related errors (73.8%) and vehicle-related defects (19.6%) were the primary reasons for hazmat tanker crashes. The most common outcomes of a hazmat tanker accident was a spill without further events (55.51%), followed by a release with fire (7.77%), and release with an explosion (2.54%). The safety situation of China's hazmat tanker transportation is grim. Such accidents not only have high spill percentages and consistently large spills but they can also cause serious consequences, such as fires and explosions.

Nobody can doubt today that hydrogen will, in the not-too-distant future, represent a very significant percentage of the total energy used by the transport sector. This study therefore consists of the modelling and simulation of energy consumption, by type of vehicle and fuel or energetic vector, in the road transport sector of the Madrid Region, during the period 2010-2050, using the MARKAL model. It has been necessary to complete this model by adding numerous specifications in order to determine the features of the Madrid Region, the richest Region in Spain. For the purpose of the study, three growth scenarios, based on short-term energy forecasts made by different official organizations, have been proposed for the energy consumption of the road transport sector in the Region. The results show a profound change in the current situation as there is a significant decrease in the consumption of fossil fuels and an increase in that of alternative non-fossil fuels and hydrogen. The latter, in particular, will rise from 0.1% in the year 2010, to around 50% in the year 2050, which will mean a drastic drop in the sector's CO 2 and atmospheric pollutant emissions. (author)

This report compares the transport by sea transport versus road for some selected scenarios that all end up in Oslo. Scenarios are chosen because they reflect realistic transportation options for products that consumers can relate to. It is therefore decided to look at the transportation of house modules from Estonia, kitchen units from Denmark, TVs from Germany and containers from Rotterdam. There are only examined some selected environmental stresses, including categories of climate change, acidification and eutrophication (excessive nutrients). Environmental impact categories are chosen for relevance (ie that transport contributes to such environmental stresses and that the environmental impact categories that may be important) and data availability (it's relevant categories for which data are lacking, such as noise and toxicity). Table A shows the results for all the examined scenarios of probable reservoir levels. One can see from the table that sea transport gives better environmental performance than the surface of all the scenarios in the categories climate change and eutrophication. For acidification is only one scenario where sea transport means less strain than land transport (transport of containers from Rotterdam). It should be emphasized that the relative contributions are greater climate change than to acidification and eutrophication for all options, and also the importance of climate change is considered to be greater than for acidification and eutrophication, Man may therefore conclude that sea transport is more environmentally friendly than road transport for all the investigated options. Underlying data are taken from real options for the transport ships and updated emissions data for trucks from environmental databases (EcoInvent). It is considered a completely new truck park in the comparisons presented above, the assumption is examined in sensitivity analyzes. With the Port as principal, it was important to have a conservative approach

Full Text Available The aim of this study is to identify the traditional Turkish motifs and its relations among present industrial designs. Traditional Turkish motifs played a very important role in 16th century onwards. The arts of the Ottoman Empire were used because of their symbolic meanings and unique styles. When we examine these motifs we encounter; Tiger Stripe, Three Spot (Çintemani, Rumi, Hatayi, Penç, Cloud, Crescent, Star, Crown, Hyacinth, Tulip and Carnation motifs. Nowadays, Turkish designers have begun to use these traditional Turkish motifs in their designs so as to create differences and awareness in the world design. The examples of these industrial designs, using the Turkish motifs, have survived and have Ottoman heritage and historical value. In this study, the Turkish motifs will be examined along with their focus on contemporary Turkish industrial designs used today.

A multi-methodological approach to study the temporal and spatial distribution of air quality related to road transport emissions in Madrid, Spain

Science.gov (United States)

Perez, Pedro; Miranda, Regina

2013-04-01

The traffic-related atmospheric emissions, composition and transport of greenhouse gases (GHGs) and air toxic pollutants (ATPs), are an important environmental problem that affect climate change and air pollution in Madrid, Spain. Carbon dioxide (CO2) affects the regional weather and particularly fine particle matter (PM) translocate to the people resulting in local health problems. As the main source of emissions comes from road transport, and subsequent combustion of fossil fuels, air quality deterioration may be elevated during weekdays and peak hours. We postulate that traffic-related air quality (CO2, methane CH4, PM, volatile organic compounds VOCs, nitrogen oxides NOx and carbon monoxide CO contents) impairs epidemiology in part via effects on health and disease development, likely increasing the external costs of transport in terms of climate change and air pollution. First, the paper intends to estimate the local air quality related to the road transport emissions of weeks over a domain covering Madrid (used as a case study). The local air quality model (LAQM) is based on gridded and shaped emission fields. The European Environmental Agency (EEA) COPERT modeling system will provide GHGs and ATPs gridded and shaped emission data and mobile source parameters, available for Madrid from preliminary emission inventory records of the Municipality of Madrid and from disaggregated traffic counts of the Traffic Engineering Company and the Metropolitan Company of Metro (METRO-Madrid). The paper intends to obtain estimates of GHGs and ATPs concentrations commensurate with available ground measurements, 24-hour average values, from the Municipality of Madrid. The comparison between estimated concentrations and measurements must show small errors (e.g. fractional error, fractional bias and coefficient of determination). The paper's expected results must determine spatial and temporal patterns in Madrid. The estimates will be used to cross check the primary local

Associations between road traffic noise and hypertension have been repeatedly documented, whereas associations with rail or total road, rail, and air (RRA) traffic noise have rarely been investigated. Moreover, most studies of noise in the environment have only taken into account the residential neighborhood. Finally, few studies have taken into account individual/neighborhood confounders in the relationship between noise and hypertension. We performed adjusted multilevel regression analyses using data from the 7,290 participants of the RECORD Study to investigate the associations of outdoor road, rail, air, and RRA traffic noise estimated at the place of residence, at the workplace, and in the neighborhoods around the residence and workplace with systolic blood pressure (SBP), diastolic blood pressure (DBP), and hypertension. Associations were documented between higher outdoor RRA and road traffic noise estimated at the workplace and a higher SBP [+1.36 mm of mercury, 95% confidence interval (CI): +0.12, +2.60 for 65-80 dB(A) vs 30-45 dB(A)] and DBP [+1.07 (95% CI: +0.28, +1.86)], after adjustment for individual/neighborhood confounders. These associations remained after adjustment for risk factors of hypertension. Associations were documented neither with rail traffic noise nor for hypertension. Associations between transportation noise at the workplace and blood pressure (BP) may be attributable to the higher levels of road traffic noise at the workplace than at the residence. To better understand why only noise estimated at the workplace was associated with BP, our future work will combine Global Positioning System (GPS) tracking, assessment of noise levels with sensors, and ambulatory monitoring of BP.

Over-the-road shock and vibration testing of the radioisotope thermoelectric generator transportation system

International Nuclear Information System (INIS)

Becker, D.L.

1997-01-01

Radioisotope Thermoelectric Generators (RTG) convert heat generated by radioactive decay into electricity through the use of thermocouples. The RTGs have a long operating life, are reasonably lightweight, and require little or no maintenance, which make them particularly attractive for use in spacecraft. However, because RTGs contain significant quantities of radioactive materials, normally plutonium-238 and its decay products, they must be transported in packages built in accordance with Title 10, Code of Federal Regulations, Part 71 (10 CFR 71). To meet these regulations, a RTG Transportation System (RTGTS) that fully complies with 10 CFR 71 has been developed, which protects RTGs from adverse environmental conditions during normal conditions of transport (e.g., shock, vibration, and heat). To ensure the protection of RTGs from shock and vibration loadings during transport, extensive over-the-road testing was conducted on the RTG'S to obtain real-time recordings of accelerations of the air-ride suspension system trailer floor, packaging, and support structure. This paper provides an overview of the RTG'S, a discussion of the shock and vibration testing, and a comparison of the test results to the specified shock response spectra and power spectral density acceleration criteria

Full Text Available Mother tongue education (or instruction plays quite a significant role in individual students’ success in both social and academic areas. A qualified mother tongue education is crucial in ensuring those students become successful adults in their later life and adopt their own culture and identities. From time to time, there might be students who have mother tongue medium education along with those who have other languages as the medium of instruction. Among those bilingual students there are children of Turkish citizens who immigrated to Western Europe as workers. Mother tongue education is a necessity for bilingual individuals to protect their identities, to adopt to the society they already live in and to learn the language used in that very society much more easily. This makes it more important for the bilingual Turkish children living in foreign countries to receive mother tongue education. In this vein, the attitudes of Turkish students, who live in England, towards the Turkish language class are examined. 105 Turkish students between 11 and 18 years enrolled in Wisdom and Namık Kemal Turkish School in the UK were requested to fill in a questionnaire. Based on their responses, their opinions about the Turkish language class were evaluated.

This article describes the state of the automobile industry and urban road transportation management in China. It reviews how the automobile industry is evolving to respond to challenges in economic development, environmental regulations, and technological change. The dynamics and barriers resulting from technological change of automobiles in response to reduction of exhaust emissions and energy-efficiency improvement are analysed. It is argued that consideration of externality costs should be integrated in automobile industrial policymaking and transportation management. Efforts need to be made to use more economic incentives for emissions reduction, and to promote technological change for cleaner vehicle development. This paper questions the current government policy of encouraging private car ownership, and suggests that improvement in public transportation systems, stronger emissions control, and technology innovation on environmental friendly automobile technologies would be relevant to China's drive toward sustainable transportation development. Social inequities resulted from automobile use is also stressed in the analysis. (author)

In this context, this work analyzed the potential, implications and experiences for biofuels with ethanol, mainly biogas and biodiesel for road transport in Brazil. (author)

Urban Integrity: The City of Nicosia, Turkish Republic of Northern Cyprus

Directory of Open Access Journals (Sweden)

Hasan ZAFERSOY

2014-12-01

Full Text Available For more than one thousand years, the island of Cyprus has borne witness to the history of different cultures and their sovereignties. In the 19th century, starting in 1877, the process of turning the Ottoman island into a British dominion opened up a new phase in the development of both the island and its cities. Nicosia began to spread outside the city walls after 1925, when the island came fully under the dominion of the British. In this period, some new roads and a square were constructed to improve urban integrity. In 1959, The Republic of Cyprus was established and the island gained independence in 1960. However, due to escalating political and social unrest, the country itself and its capital Nicosia were divided into two parts in 1974. The new situation opened up another phase in the development of the northern part and its capital, affecting social life in terms of integrity and coherence. It also brought with it negative pressures on the economy as a result of the embargo applied by the western world. In this new situation, there even existed practical difficulties in terms of how the city should be referenced, with some long and complicated alternatives suggested: Turkish Republic of Northern Cyprus City of Nicosia, North Nicosia etc. In this essay, the term Nicosia is used for ease of expression.
It is interesting to see that various studies have laid emphasis on the possibility of integrating cities via improvement of pedestrian accessibility. The same effect has been studied and sought out recently by several researchers on vehicle transportation. In this study, the Nicosia transportation network is analysed using the space syntax method, with a view to determining ways in which the integrity of the city’s structure could be developed under different scenarios.

Participants were 50 second grade learners in the English Language Teaching Departments of Hacettepe University (N=10, Mehmet Akif Ersoy University (N=10, and Uludag University (N=30 who had already taken courses about learner autonomy.  The data were collected by means of a questionnaire which had two Likert-scale sections and an open-ended questions section. The first Likert-scale section contained 15 characteristics of autonomous learners each of which was rated by the participants in a scale from strongly disagree to agree, from 1 to 5. In the second Likert-scale section, the participants were asked to rate the Turkish education system’s five basic elements such as school curriculums, course materials, approaches used by the teachers in classrooms, learning activities, and classroom settings. Additionally, learners’ opinions about their awareness and understanding of learner autonomy were gathered by five open ended questions. The results proposed that the participants were aware of learner autonomy, and had the characteristics of autonomous learners. On the other hand, results showed that the Turkish education system was not suitable for autonomous learners and did not foster learner autonomy. The findings suggested that the Turkish education system should be designed again in such a way to support the autonomous learners and to foster learner autonomy in all sections of the education.

Evaluation of Alternatives for the Passenger Road Transport Sector in Europe: A Life-Cycle Assessment Approach

Full Text Available The road passenger transport is responsible for a large share of energy consumption and pollutants emission in Europe. Efforts have been made in the definition of new policies to reduce the environmental impacts of this sector. However, an integrated and consistent assessment of the most promising policies is required, using specific European indicators. For that matter, a life-cycle analysis was applied to the road passenger transport, for the European Union with 27 countries (EU27 in 2010, following a basket-of-products methodology and considering three main stages: production, use, and end-of-life of vehicles. Simapro 8 software was used, along with Ecoinvent 3 database and the impact assessment method International Reference Life Cycle Data System (ILCD 2011 Midpoint+. Changes in vehicle production processes, vehicle constitution, and energy sources for vehicle propulsion were analyzed. The policies resulting in a decrease in all impact categories are the use of smaller or lightweight vehicles by positively influencing use, production, and end-of-life of vehicles. The use of more recent vehicles technology or diesel vehicles show substantial reductions in, respectively, five and eight impact categories (out of 15, justifying their adoption in the European fleet. Generally, the most notorious policies compared to the actual transport paradigm, like compressed natural gas (CNG, biofuels, or electric vehicles use, show the greatest reduction in climate change (up to 46% but also a very significant rise of impacts in the categories that in the conventional basket-of-products already resulted in the worst indicators after normalization.

Freight transport has been receiving increasing attention in both literature and practice following the growing recognition of its importance in urban transport planning. This paper analyses historical and projected road freight CO{sub 2} emissions in the city of London and explores the potential mitigation effect of a set of freight transport policies and logistics solutions. Findings indicate a range of policies with potential to reduce emissions in the period up to 2050. However, this reduction would appear to only be capable of partly counterbalancing the projected increase in freight traffic. More profound behavioural measures therefore appear to be necessary for London's CO{sub 2} emissions reduction targets to be met.

Full Text Available The present study aims to investigate the pronunciation problems of Turkish learners of English as a foreign language (Turkish EFL learners due to the orthography system of English. Orthography is a standardized system for using a particular writing system (script to write a particular language. It includes rules of spelling, and may also concern other elements of the written language such as punctuation and capitalization. It is clear that English is a non-phonetic and Turkish is a phonetic language, so it is very natural for the Turkish EFL learners to have some phonological problems in learning English. The author has done a contrastive study concerning three linguistic systems, i.e. consonants, vowels and syllable structures of English and Turkish to find the causes of the problems to be used in teaching English as a foreign language to Turks. The results of the study showed that the problems under discussion are caused by some differences between the orthography and the phonology of the two languages. As a result, English teachers, to be helpful, should focus on the differences and help the Turkish learners overcome the pronunciation problems. The author of the paper believes that an English teacher should be both aware of the differences and be able to teach them effectively to the Turkish EFL learners.

Many studies nowadays make the effort of determining personal exposure rather than estimating exposure at the residential address only. While intra-urban air pollution can be modeled quite easily using interpolation methods, estimating exposure in transport is more challenging. The aim of this study is to investigate which factors determine black carbon (BC) concentrations in transport microenvironments. Therefore personal exposure measurements are carried out using portable aethalometers, trip diaries and GPS devices. More than 1500 trips, both by active modes and by motorized transport, are evaluated in Flanders, Belgium. GPS coordinates are assigned to road segments to allow BC concentrations to be linked with trip and road characteristics (trip duration, degree of urbanization, road type, traffic intensity, travel speed and road speed). Average BC concentrations on highways (10.7 μg/m 3 ) are comparable to concentrations on urban roads (9.6 μg/m 3 ), but levels are significantly higher than concentrations on rural roads (6.1 μg/m 3 ). Highways yield higher BC exposures for motorists compared to exposure on major roads and local roads. Overall BC concentrations are elevated at lower speeds ( 3 for roads with less than 500 veh/h, up to 12 μg/m 3 for roads with over 2500 veh/h). Traffic intensity proved to be the major explanatory variable for in-vehicle BC exposure, together with timing of the trip and urbanization. For cyclists and pedestrians the range in BC exposure is smaller and models are less predictive; for active modes exposure seems to be influenced by timing and degree of urbanization only. - Highlights: ► Aethalometers, an electronic diary and GPS were used to measure exposure in transport ► More than 1500 trips with active modes and in motorized transport are studied ► Exposure is higher on highways, in urban areas and during traffic peak hours. ► Traffic intensity is the major explanatory variable for in-vehicle BC exposure. ► Exposure

Source identification of hydrocarbon contaminants and their transportation over the Zonguldak shelf, Turkish Black Sea

Under great anthropogenic pressure due to the substantial freshwater input from the surrounding industrial and agricultural areas, especially central and middle-Eastern Europe, the Black Sea basin is ranked among the most ecologically threatened water bodies of the world. Oil levels are unacceptable in many coastal areas perilously close to polluted harbors and many river mouths; the places presenting the highest levels of bio-diversity and having a high socio-economic importance due to human use of coastal resources. There are about sixty sources of pollution which resulted in "hot spots" having disastrous impacts on sensitive marine and coastal areas and needing immediate priorities for action. Beyond such land-based sources, trans-boundary pollution sources from Black Sea riparian countries, heavy maritime traffic, particularly involving petroleum transports and fishing boats, and the improper disposal of ballast and bilge waters and solid waste are also important marine sources of pollution. Found in fossil fuels such as Polycyclic Aromatic Hydrocarbons are generated by incomplete combustion of organic matter. In order to estimate their distribution in sediment and their sources, they were monitored from the bottom samples offshore the Zonguldak industry region, one of the most polluted spots in the Turkish Black Sea. There the budget of pollutants via rivers is not precisely known due to an evident lack of data on chemical and granulometric composition of the river runoff and their fluxes. Therefore the marine sediments, essential components of marine ecosystems, are very important in our estimating the degree of the damage given to the ecosystem by such inputs. Realization of the sources and transport of these contaminants will be a critical tool for future management of the Zonguldak industry region and its watershed. The sea bottom in study area is composed of mainly sand and silt mixtures with small amount of clay. Geochemical analyses have shown that oil

Full Text Available Recently in mass media we can find the idea about a new Silk Road or the concept of "Silk Road Economic Belt" which has been formulated by the Chinese PresidentXi Jinping on September 7,2013, during his official visit to Kazakhstan. This project is not only the creation of a transport, power and trade corridor, and also the project which will promote development of tourism in the region and to strengthening of cultural exchanges of China with the countries of Central Asia, it also includes construction of a network of high-speed fiber-optical networks. The economic strip of the Silk Road will begin in China and pass across the Central and the Southern Asia, part of branches across the territory of the Russian Federation and to leave to Europe. This international investment project assumes creation of a continental transport way. For implementation of overland part of "A great Silk Road is a three railway corridors (northern, central have to be constructed and southern They have form a basis for development of other means of transport, including automobile subsequently. Construction of these three railway corridors acts as the most important and necessary stage of implementation of the project. The government of China declares that creation of an economic belt of the Silk way is a revival of once prospering trade-transport and cultural corridor from Asia to Europe which will promote activization of a friendly exchange between the people of the different countries. Further all this has to connect trade and economic space of Europe and Asia in a whole that has to serve implementation of deeper economic cooperation, between the countries participating in him, to increase in a trade turnover and expansion of scientific and technical exchanges between them.

Nobody can doubt today that hydrogen will, in the not-too-distant future, represent a very significant percentage of the total energy used by the transport sector. This study therefore consists of the modelling and simulation of energy consumption, by type of vehicle and fuel or energetic vector, in the road transport sector of the Madrid Region, during the period 2010-2050, using the MARKAL model. It has been necessary to complete this model by adding numerous specifications in order to determine the features of the Madrid Region, the richest Region in Spain. For the purpose of the study, three growth scenarios, based on short-term energy forecasts made by different official organizations, have been proposed for the energy consumption of the road transport sector in the Region. The results show a profound change in the current situation as there is a significant decrease in the consumption of fossil fuels and an increase in that of alternative non-fossil fuels and hydrogen. The latter, in particular, will rise from 0.1% in the year 2010, to around 50% in the year 2050, which will mean a drastic drop in the sector's CO{sub 2} and atmospheric pollutant emissions.

NEGATIVE CURRENCY-RISK-EXPOSURE FOR TURKISH EQUITIES

Directory of Open Access Journals (Sweden)

Salvatore J. Terregrossa

2016-04-01

Full Text Available Currency-risk-exposure is an issue for Turkish equities, from two different angles: internationaltrade and foreign-portfolio-investment. The likely effect is positive for the former, and negative for the latter aspect. Consequently, the overall or net effect on equity value depends on which of these aspects of currency-risk-exposure has the greater impact. The present empirical analysis estimates currency risk of Turkish equities within a multi-factor regression setting, utilizing the framework of the Security Market Plane (SMP model. The SMP model embodies a conditional relation among three variables: beta, realized excess market-return, and expected excess portfolio-return. The SMP empirical framework is extended to include a currency-risk-factor in the present analysis. The currency-risk-factor is specified as the excess return to holding foreign currency (€; $, relative to holding domestic currency (Turkish Lira. The SMP-related factor is the cross-product term of beta and realized excess market-return (β it rMt . A regression of realized excess portfolio-returns against the corresponding currency-risk-factor and cross product-term (β it rMt finds that the Turkish stocks represented in the analysis generally have overall negative currency-risk-exposure; suggesting that unexpected currency depreciation generally leads to lower values for Turkish stocks (and portfolios of Turkish stocks. Thus, after accounting for the SMP-related interaction-effect between beta and realized excess marketreturn, currency risk is found to command a premium for the Turkish stocks represented in the analysis.

Danish emission inventories for road transport and other mobile sources. Inventories until year 2006

Energy Technology Data Exchange (ETDEWEB)

Winther, M.

2008-09-15

This report explains the parts of the Danish inventories related to road transport and other mobile sources. Emission results are shown for CO{sub 2}, CH{sub 4}, N{sub 2}O, SO{sub 2}, NO{sub X}, NMVOC, CO, particulate matter (PM), heavy metals, dioxins and PAH. From 1990-2006 the fuel use and CO{sub 2} emissions for road transport have increased by 36 %, and CH{sub 4} emissions have decreased by 51 %. A N{sub 2}O emission increase of 29 % is related to the relatively high emissions from older gasoline catalyst cars. The 1985-2006 emission decreases for PM (exhaust only), CO, NO{sub X} and NMVOC are 30, 69, 28 and 71 % respectively, due to the introduction of vehicles complying with gradually stricter emission standards. For SO{sub 2} the emission drop is 99% (due to reduced sulphur content in the diesel fuel), whereas the NH{sub 3} emissions increase by 3065% (due to the introduction of catalyst cars). For other mobile sources the calculated emission changes for CO{sub 2} (and fuel use), CH{sub 4} and N{sub 2}O are -10, 5 and -11%, from 1990 to 2006. The emissions of SO{sub 2}, particulates (all size fractions), NO{sub X}, NMVOC and CO have decreased by 88, 56, 14, 12 and 9% from 1985 to 2006. For NH{sub 3} the emissions have increased by 8% in the same time period. Uncertainties for the emissions and trends have been estimated. (au)

The driver, the road, the rules … and the rest? A systems-based approach to young driver road safety.

Science.gov (United States)

Scott-Parker, B; Goode, N; Salmon, P

2015-01-01

The persistent overrepresentation of young drivers in road crashes is universally recognised. A multitude of factors influencing their behaviour and safety have been identified through methods including crash analyses, simulated and naturalistic driving studies, and self-report measures. Across the globe numerous, diverse, countermeasures have been implemented; the design of the vast majority of these has been informed by a driver-centric approach. An alternative approach gaining popularity in transport safety is the systems approach which considers not only the characteristics of the individual, but also the decisions and actions of other actors within the road transport system, along with the interactions amongst them. This paper argues that for substantial improvements to be made in young driver road safety, what has been learnt from driver-centric research needs to be integrated into a systems approach, thus providing a holistic appraisal of the young driver road safety problem. Only then will more effective opportunities and avenues for intervention be realised. Copyright © 2014 Elsevier Ltd. All rights reserved.

Societal Economics of the European Union Liquid Fuel Consumption for Road Transportation

Directory of Open Access Journals (Sweden)

Alfred Wong

2016-08-01

Full Text Available In order for the EU to achieve its goal of 10% biofuel for all EU motor vehicles by 2020, a substantial amount of biofuel as well as a biofuel feedstock would need to be imported largely from developing countries where the climate is warm and labor is inexpensive. But there may never be sufficient supply to fulfill the evergrowing demand for biofuel for road transportation in the EU, even as motor vehicles are increasingly becoming more fuel-efficient. The constraint to realizing an effective and equitable reduction in greenhousegas emission is the overbearing political economics of neoliberalism. A different remedial strategy is needed to address the dual problems of the excessive uses of motor fuels and greenhouse-gas emission.

Full Text Available The language used by a poet or an author in a literary work in verse or prose, and the way he uses idioms, proverbs and literary arts in that language indicate the success of his art. The achievement of author in this matter makes him well known in the country where he lives. However, the topic choice is as important as an artist’s language skills. That’s why poets and authors prefer universal subjects such as love, death, religion, religious personalities (like prophets, saints, etc. and humanity (man's way of living and right to live in their works. If artists produce universal subjects with a clear language, a fluent wording and a strong story line, this achievement makes them famous both nationally and internationally. This fact can also be applied to the literature of any nation. Literary works containing local subjects cannot take their place in the world’s literary history. Classical Turkish literature (Ottoman Period Turkish Literature is extremely rich in subject matter. The period in which Classical Turkish Literature continued its existence was the period when the Ottoman state dominated large geographical regions in Asia, Europe and Africa. Accordingly, the lifestyles, beliefs, traditions and customs of people from different religions, races and cultures living in these geographies; in other words, the issues that are important to these people were also reflected in the literature produced in this period. The subject of this article Virgin Mary is an important religious and a historical personality primarily for the Ottoman state’s Christians and Muslim subjects as well as those who weren’t the subjects of Ottoman Empire. In this article, first how Virgin Mary took part in the two most important sources of Classical Turkish literature, Koran and the hadiths will be summarized.

Gerulis, Eduardo

2013-01-01

The radiation doses to workers in the transport of radioactive material should be as low as reasonably achievable. The average doses of drivers and loaders, sampled in this thesis should be decreased. The demonstration of doses control in a road vehicle with radioactive material required by the current Brazilian regulation, CNEN NE 5.01 should be written in its own printed form with exposure values obtained in normally occupied positions from workers and members of the public, even when the consignment does not need 'exclusive use' (⅀IT ≤50). Through bibliographic research, modeling and field research, this research work shows that this demonstration of the control should be done by writing the registration accumulation of load, limited (⅀IT ≤50), also in the own printed form. It is for a better control method, in order to avoid the use of measuring equipment, to build standardization with foreign regulations, to the current occupational doses of radioprotection technicians, the costs and time, (important for consignment with radiopharmaceuticals short half-life) would be all smaller. Exposure values of the parameters used with this method are smaller than regulatory limits. The segregation distances between loads and the cabins of vehicles shall be showed by Brazilian regulation updated to contribute to these aims. (author)

Heavy trucks are primarily responsible for pavement damage to the nation's highways. In this paper we evaluate the pavement damage caused by coal trucks. We analyze the chief source of pavement damage (vehicle weight per axle, not total vehicle weight) and the chief cost involved (the periodic overlay that is required when a road's surface becomes worn). This analysis is presented in two stages. In the first section we present a synopsis of current economic theory including simple versions of the formulas that can be: used to calculate costs of pavement wear. In the second section we apply this theory to a specific example proximate to the reference environment for the Fuel Cycle Study in New Mexico in order to provide a numerical measure of the magnitude of the costs

The objective of this article is to assess the status of road safety in Asia and present accident and injury prevention strategies based on global road safety improvement experiences and discuss the way forward by indicating opportunities and countermeasures that could be implemented to achieve a new level of safety in Asia. This study provides a review and analyses of data in the literature, including from the World Health Organization (WHO) and World Bank, and a review of lessons learned from best practices in high-income countries. In addition, an estimation of costs due to road transport injuries in Asia and review of future trends in road transport is provided. Data on the global and Asian road safety problem and status of prevention strategies in Asia as well as recommendations for future actions are discussed. The total number of deaths due to road accidents in the 24 Asian countries, encompassing 56% of the total world population, is 750,000 per year (statistics 2010). The total number of injuries is more than 50 million, of which 12% are hospital admissions. The loss to the economy in the 24 Asian countries is estimated to around US$800 billion or 3.6% of the gross domestic product (GDP). This article clearly shows that road safety is causing large problems and high costs in Asia, with an enormous impact on the well-being of people, economy, and productivity. In many Asian low- and middle-income countries, the yearly number of fatalities and injuries is increasing. Vulnerable road users (pedestrians, cyclists, and motorcyclists combined) are particularly at risk. Road safety in Asia should be given rightful attention, including taking powerful, effective actions. This review stresses the need for reliable accident data, because there is considerable underreporting in the official statistics. Reliable accident data are imperative to determine evidence-based intervention strategies and monitor the success of these interventions and analyses. On the other

Potential emissions reduction in road transport sector using biofuel in developing countries

Use of biofuels as transport fuel has high prospect in developing countries as most of them are facing severe energy insecurity and have strong agricultural sector to support production of biofuels from energy crops. Rapid urbanization and economic growth of developing countries have spurred air pollution especially in road transport sector. The increasing demand of petroleum based fuels and their combustion in internal combustion (IC) engines have adverse effect on air quality, human health and global warming. Air pollution causes respiratory problems, adverse effects on pulmonary function, leading to increased sickness absenteeism and induces high health care service costs, premature birth and even mortality. Production of biofuels promises substantial improvement in air quality through reducing emission from biofuel operated automotives. Some of the developing countries have started biofuel production and utilization as transport fuel in local market. This paper critically reviews the facts and prospects of biofuel production and utilization in developing countries to reduce environmental pollution and petro dependency. Expansion of biofuel industries in developing countries can create more jobs and increase productivity by non-crop marginal lands and wastelands for energy crops plantation. Contribution of India and China in biofuel industry in production and utilization can dramatically change worldwide biofuel market and leap forward in carbon cut as their automotive market is rapidly increasing with a souring proportional rise of GHG emissions.

How can Saudi Arabia use the Decade of Action for Road Safety to catalyse road traffic injury prevention policy and interventions?

Science.gov (United States)

Al Turki, Yousef Abdullah

2014-01-01

Motor vehicle accidents are the leading cause of death in adolescents and young adults worldwide. Nearly three-quarters of road deaths occur in developing countries and men comprise a mean 80% of casualties. The rate of road traffic accidents caused by four-wheeled vehicles is the highest globally reported road traffic accidents statistic. In Saudi Arabia, the motor vehicle is the main means of transportation with one person killed and four injured every hour. Over 65% of accidents occur because of vehicles travelling at excess speed and/or drivers disobeying traffic signals. Road traffic injuries cause considerable economic losses to victims, their families, and to nations as a whole. Strategic prevention plans should be implemented soon by various sectors (health, police, transport, and education) to decrease the mortality and morbidity among adolescent and young age group. Strong and effective coordination between ministry of health and other ministries together with World Health Organization and other related organisations will be an important step towards implementing the international Decade of Action for Road Safety (2011-2020). The aim of this review article is to highlight some aspects of the health impacts of road traffic accidents.

Turkish cultural heritage: a cup of coffee

Birsen Yılmaz

2017-12-01

Full Text Available Setting out a fabulous journey from a tiny bean, coffee is the stimulant of the heart and mind and a mysterious plant that strengthens friendship and also takes your tiredness away during the day. Although information on how and where the coffee came from is not clear, Sheikh Şazeli is regarded as the “father” by coffee makers. The word coffee originates from “Kaffa”, a primary coffee production center in Abyssinia, Africa, which can be considered the homeland of coffee. According to this consideration, in Abyssinia, coffee was consumed with bread; it was then pulped and brought to Yemen, and Yemeni people started to cultivate coffee. The word “kahve” in Turkish does not mean the coffee plant like its synonym in Arabic but means the beverage made by boiling. Turkish coffee is a blend of high-quality Arabic-type coffee beans, originating from Brazil and Central America and moderately roasted and ground finely. The way it is prepared differentiates Turkish coffee from others. This coffee was called Turkish coffee because of a new method of preparation invented by Turkish people where it is boiled in copper coffee pots. Turkish coffee that has spread around the world with this name has been an indispensable part of the cultural and social history of Turks.

Full Text Available In Africa, roads are the dominant mode of passenger and freight transport, for which the need is growing rapidly. It is noticeable that most of the African countries do not do enough to ensure the sustainability of road infrastructure as it has been widely reported that roads are affected, to varying degrees, by premature deterioration. Most of the African countries have adopted institutional reforms, notably entailing the creation of road funds and road agencies, and made significant progress on road maintenance.

In Africa, roads are the dominant mode of passenger and freight transport, for which the need is growing rapidly. It is noticeable that most of the African countries do not do enough to ensure the sustainability of road infrastructure as it has been widely reported that roads are affected, to varying degrees, by premature deterioration. Most of the African countries have adopted institutional reforms, notably entailing the creation of road funds and road agencies, and made significant progress on road maintenance. However, many challenges remain to be addressed in all of them to ensure appropriate maintenance. Although spending on road maintenance has increased over time in all African countries it remains insufficient to cover the needs. Poorly maintained roads constrain mobility, significantly raise vehicle operating costs, increase accident rates and their associated human and property costs, and aggravate isolation, poverty, poor health, and illiteracy in rural communities. This paper focuses, in particular, on road maintenance in some African countries considering types of road maintenance and the different approaches aiming at a comparison to reflect on similarities and differences.

Bengi-Arslan, L; Verhulst, F C; van der Ende, J; Erol, N

1997-11-01

Parents' reports of problem behaviors in 2,081 Dutch children, 3,127 Turkish children in Ankara and 833 Turkish immigrant children living in The Netherlands, aged 4-18 years, were compared. Dutch and Turkish versions of the Child Behavior Checklist (CBCL) were used. Immigrant children were scored higher than Dutch children on 6 of the 11 CBCL scales, most markedly on the Anxious/Depressed scale. Immigrant children were scored higher than Ankara children on five CBCL scales. However, these differences were much smaller than those found between immigrant and Dutch children. Furthermore, immigrant children's Total Problem scores did not differ from those for Ankara children. Turkish immigrant children have very similar patterns of parent-reported problem behaviors to children living in Turkey, although both groups of Turkish children showed higher levels of parent-reported problem behaviors than Dutch children. The higher scores for Turkish children on the Anxious/Depressed scale compared with their Dutch peers may be explained by cultural differences in parental perception of children's problem behaviors, as well as the threshold for reporting them, or by cultural differences in the prevalence of problems, for instance as the result of cross-cultural differences in child-rearing practice. More research is needed to test the degree to which Turkish immigrant parents tend to preserve their cultural characteristics and child-rearing practices in Dutch society.

The transportation of British nuclear weapons by road. Hiroshima is waiting to happen in the UK

This leaflet describes the transportation of nuclear weapons on United Kingdom roads. The author seeks to question the safety and desirability of such activities, and points out the potential hazards to humans and the environment should convoy accidents occur. Correspondence is included between the author and various Government sources to illustrate the difficulty of obtaining full, accurate information on the design and safety of weapons transportation vehicles and the reasons and frequency of weapons convoys. The author contrasts these difficulties with the free available government information in the United States of America because of the Freedom of Information Act. Readers are urged to contribute to monitoring the routes and occurrence of UK weapons convoys to assist in data collection. (UK)

The impact of a future H2-based road transportation sector on the composition and chemistry of the atmosphere - Part 2: Stratospheric ozone

The prospective future adoption of hydrogen to power the road transportation sector could greatly improve tropospheric air quality but also raises the question whether the adoption would have adverse effects on stratospheric ozone. The possibility of these undesirable impacts must be fully evaluated to guide future policy decisions. Here we evaluate the possible impact of a future (2050) H2-based road transportation sector on stratospheric composition and chemistry, especially on stratospheric ozone, with the MOZART chemical transport model. Since future growth is highly uncertain we evaluate the impact for two world evolution scenarios, one based on a high emitting scenario (IPCC A1FI) and the other on a low emitting scenario (IPCC B1), as well as two technological options: H2 fuel cells and H2 internal combustion engines. We assume a H2 leakage rate of 2.5% and a complete market penetration of H2 vehicles in 2050. The model simulations show that a H2-based road transportation sector would reduce stratospheric ozone concentrations as a result of perturbed catalytic ozone destruction cycles. The magnitude of the impact depends on which growth scenario the world evolves and which H2 technology option is applied. For the same world evolution scenario, stratospheric ozone decreases more in the H2 fuel cell scenarios than in the H2 internal combustion engine scenarios because of the NOx emissions in the latter case. If the same technological option is applied, the impact is larger in the A1FI emission scenario. The largest impact, a 0.54% decrease in annual average global mean stratospheric column ozone, is found with a H2 fuel cell type road transportation sector in the A1FI scenario; whereas the smallest impact, a 0.04% increase in stratospheric ozone, is found with applications of H2 internal combustion engine vehicles in the B1 scenario. The impacts of the other two scenarios fall between the above two bounding scenarios. However, the magnitude of these changes is

To determine the influence of transportation by road and air on heart rate (HR) and HR variability (HRV) in horses. Animals-6 healthy horses. ECG recordings were obtained from horses before (quarantine with stall rest [Q]; 24 hours) and during a journey that included transportation by road (RT; 4.5 hours), waiting on the ground in an air stall (W; 5.5 hours), and transportation by air (AT; 11 hours); HR was determined, and HRV indices of autonomic nervous activity (low-frequency [LF; 0.01 to 0.07 Hz] and high-frequency [HF; 0.07 to 0.6 Hz] power) were calculated. Mean ± SD HRs during Q, RT, W, and AT were 38.9 ± 1.5 beats/min, 41.7 ± 5.6 beats/min, 41.5 ± 4.3 beats/min, and 48.8 ± 5.6 beats/min, respectively; HR during AT was significantly higher than HR during Q. The LF power was significantly higher during Q (3,454 ± 1,087 milliseconds(2)) and AT (3,101 ± 567 milliseconds(2)) than it was during RT (1,824 ± 432 milliseconds(2)) and W (2,072 ± 616 milliseconds(2)). During Q, RT, W, and AT, neither HF powers (range, 509 to 927 milliseconds(2)) nor LF:HF ratios (range, 4.1 to 6.2) differed significantly. The HR during RT was highly correlated with LF power (R(2) = 0.979), and HR during AT was moderately correlated with the LF:HF ratio (R(2) = 0.477). In horses, HR and HRV indices during RT and AT differed, suggesting that exposure to different stressors results in different autonomic nervous influences on HR.

Sahin, Bahri; Yilmaz, Huseyin; Ust, Yasin; Guneri, Ali Fuat; Gulsun, Bahadir; Turan, Eda

2014-01-01

A different intermodal transportation model based on cost analysis considering technical, economical, and operational parameters is presented. The model consists of such intermodal modes as sea-road, sea-railway, road-railway, and multimode of sea-road-railway. A case study of cargo transportation has been carried out by using the suggested model. Then, the single road transportation mode has been compared to intermodal modes in terms of transportation costs. This comparison takes into account the external costs of intermodal transportation. The research reveals that, in the short distance transportation, single transportation modes always tend to be advantageous. As the transportation distance gets longer, intermodal transportation advantages begin to be effective on the costs. In addition, the proposed method in this study leads to determining the fleet size and capacity for transportation and the appropriate transportation mode.

The European road sector is vulnerable to extreme weather phenomena, which can cause large socio-economic losses. Almost every year there occur several weather triggered events (like heavy precipitation, floods, landslides, high winds, snow and ice, heat or cold waves, etc.), that disrupt transportation, knock out power lines, cut off populated regions from the outside and so on. So, in order to avoid imbalances in the supply of vital goods to people as well as to prevent negative impacts on health and life of people travelling by car it is essential to know present and future threats to roads. Climate change might increase future threats to roads. CliPDaR focuses on parts of the European road network and contributes, based on the current body of knowledge, to the establishment of guidelines helping to decide which methods and scenarios to apply for the estimation of future climate change based challenges in the field of road maintenance. Based on regional scale climate change projections specific road-impact models are applied in order to support protection measures. In recent years, it has been recognised that it is essential to assess the uncertainty and reliability of given climate projections by using ensemble approaches and downscaling methods. A huge amount of scientific work has been done to evaluate these approaches with regard to reliability and usefulness for investigations on possible impacts of climate changes. CliPDaR is going to collect the existing approaches and methodologies in European countries, discuss their differences and - in close cooperation with the road owners - develops a common line on future applications of climate projection data to road impact models. As such, the project will focus on reviewing and assessing existing regional climate change projections regarding transnational highway transport needs. The final project report will include recommendations how the findings of CliPDaR may support the decision processes of European

The Methodology of Selecting the Transport Mode for Companies on the Slovak Transport Market

Černá, Lenka; Zitrický, Vladislav; Daniš, Jozef

2017-03-01

Transport volume in the Slovak Republic is growing continuously every year. This rising trend is influenced by the development of car industry and its suppliers. Slovak republic has also a geographic strategy position in middle Europe from the side of transport corridors (east-west and north-south). The development of transport volume in freight transport depends on the transport and business processes between the European Union and China and it is an opportunity for Slovak republic to obtain transit transport flows. In the Slovak Republic, road transport has a dominant position in the transport market. The volume of road transport has gradually increased over the past years. The increase of road transport is reflected on the highways and speed roads in regions which have higher economic potential. The increase of rail transport as seen on the main rail corridors is not as significant as in road transport. Trade globalization also has an influence on the increase of transport volume in intermodal transport. Predicted increase in transport volume for this transport mode is from 2,3 mil ton per year at present to 8 mil ton in the year 2020. Selection of transport mode and carrier is an important aspect for logistic management, because companies (customers) want to reduce the number of carriers which they trade and they create the system of several key carriers. Bigger transport volume and more qualitative transport service give a possibility to reduce transport costs. This trend is positive for carriers too, because the carriers can focus only on the selected customers and provide more qualitative services. The paper is focused on the selection of transport mode based on the proposed methodology. The aims of the paper are, definition of criteria which directly influence the selection of transport modes, determination of criteria based on the subjectively methods, creation of process for the selection of transport modes and practical application of proposed

In spite of being an essential part of the system of automobility and as such playing an important role in the development of urban landscapes, road networks seldom attracts much attention among architects involved in the planning and design of urban landscapes. One reason is probably found...... in the dominance of the zoning approach to planning, where road planning easily becomes isolated and reduced to a matter of traffic regulation and transport economy. Another possible reason could be, as suggested by the Australian landscape architect Christopher Sawyer, that road networks like other...... as landscape architects engage with road networks in profound ways, which moves beyond the purely visual and pictorial? Is it possible to conceptually (re)locate road networks in the landscape? The paper will address these questions by discussing different understandings of landscape and its relation...

Full Text Available Major roads in Yemen are not paved and its population density is high in coastal areas, implementing the idea of intermodal transportation method all over the coastline will give the product industries a huge advantages, due to its attractive solutions to the poor transportation infrastructure and its extremely limited road transportation system. The transport of goods in Yemen depends heavily on road transport in the absence of rail transport and limited movement by air transport and its high cost, the private sector provides the bulk of land transport services (goods and has accompanied the performance of road transport activities in the absence of regulation and supervision. In this research paper the author intends to analyse and develop optimal intermodal freight transportation plans for product shipping in Yemen by using two modes of transport (truck, ship without any handling of the freight itself when changing modes. Using intermodal transportation is vital for the product movement and supplies when single mode alternative becomes unusable or infeasible. The author intends to use quantitative research method, plan and execute fieldwork, collecting data form freight companies (truck, ship, local factories, Ministry of Transportation, etc. Compile preliminary maps of roads condition and population density. First the author intends to visit the Ministry of Transport to closely monitor the program and objectives of the Ministry and the secret of work and projects in which it is implemented and meet with its representative for the purpose of collecting data and evidence of the difficulties it faces in order to become familiar with it Comprehensively and directly on its problems and study the possible solutions. , the author will intend to visit Aden and Hodeida ports to view the service and facilities for a better understanding of the processes and to examine the availabilities of intermodal transportation freight and collect data of sea

The purpose of this cross-cultural study was to describe and compare US and Turkish children's observational knowledge of the day and night cycle and to identify similarities predicted by framework theory. Fifty-six (27 US and 29 Turkish) young children (ages 48-60 months) participated in the study. Semi-structured interviews were individually conducted, digitally recorded, transcribed, and analyzed using the constant comparative method. The results demonstrate that preschoolers from the two cultures are able to make comparable informal observations of the sky, and their observational knowledge includes many similarities, with one exception, as predicted by framework theory. US children were more likely to perform better than the Turkish children on the question about the time of observation for the moon. Although science concepts and skills are better represented in US early childhood education programs than the Turkish program, the results suggest that this advantage did not translate into performance differences between US and Turkish children.

Natural hazard impacts on transport systems: analyzing the data base of transport accidents in Russia

Science.gov (United States)

Petrova, Elena

2015-04-01

We consider a transport accident as any accident that occurs during transportation of people and goods. It comprises of accidents involving air, road, rail, water, and pipeline transport. With over 1.2 million people killed each year, road accidents are one of the world's leading causes of death; another 20-50 million people are injured each year on the world's roads while walking, cycling, or driving. Transport accidents of other types including air, rail, and water transport accidents are not as numerous as road crashes, but the relative risk of each accident is much higher because of the higher number of people killed and injured per accident. Pipeline ruptures cause large damages to the environment. That is why safety and security are of primary concern for any transport system. The transport system of the Russian Federation (RF) is one of the most extensive in the world. It includes 1,283,000 km of public roads, more than 600,000 km of airlines, more than 200,000 km of gas, oil, and product pipelines, 115,000 km of inland waterways, and 87,000 km of railways. The transport system, especially the transport infrastructure of the country is exposed to impacts of various natural hazards and weather extremes such as heavy rains, snowfalls, snowdrifts, floods, earthquakes, volcanic eruptions, landslides, snow avalanches, debris flows, rock falls, fog or icing roads, and other natural factors that additionally trigger many accidents. In June 2014, the Ministry of Transport of the RF has compiled a new version of the Transport Strategy of the RF up to 2030. Among of the key pillars of the Strategy are to increase the safety of the transport system and to reduce negative environmental impacts. Using the data base of technological accidents that was created by the author, the study investigates temporal variations and regional differences of the transport accidents' risk within the Russian federal regions and a contribution of natural factors to occurrences of different

Many consortia and international projects have investigated the human genetic variation of a large number of ethno-geographic groups. However, populations with peculiar genetic features, such as the Turkish population, are still absent in publically available datasets. To explore the genetic predisposition to health-related traits of the Turkish population, we analyzed 34 genes associated with different health-related traits (for example, lipid metabolism, cardio-vascular diseases, hormone metabolism, cellular detoxification, aging and energy metabolism). We observed relevant differences between the Turkish population and populations with non-European ancestries (that is, Africa and East Asia) in some of the investigated genes (that is, AGT, APOE, CYP1B1, GNB3, IL10, IL6, LIPC and PON1). As most complex traits are highly polygenic, we developed polygenic scores associated with different health-related traits to explore the genetic diversity of the Turkish population with respect to other human groups. This approach showed significant differences between the Turkish population and populations with non-European ancestries, as well as between Turkish and Northern European individuals. This last finding is in agreement with the genetic structure of European and Middle East populations, and may also agree with epidemiological evidences about the health disparities of Turkish communities in Northern European countries.

Full Text Available The paper deals with the issue of efficiency of public passenger transport through financial support from public funds from the perspective of improving road safety. The aim is to verify the hypothesis that financing public passenger transport from public funds is a significant tool to influence the number of passengers carried by individual automobile transport, and thus it can be used a tool for influencing road safety in a particular territory. The first part of the paper analyses the sources for financial support of public passenger transport. The next part describes the assumptions for improving road safety through increasing the support of public passenger transport. The last part analyses possible impacts of financing public passenger transport on the road safety in relation to the specified hypothesis.

The present study assessed the psychometric properties of the Frustration Discomfort Scale for Turkish college students. The Frustration Discomfort Scale (FDS), Procrastination Assessment Scale-Student, and Rosenberg Self-Esteem Scale were administered to a sample of 171 (98 women, 73 men) Turkish college students. The results of the confirmatory factor analysis yielded fit index values demonstrating viability of the four-dimensional solution as in the original. Findings also revealed that, as predicted, the Discomfort Intolerance subscale of Turkish FDS was most strongly correlated with procrastination. Overall results provided evidence for the factor validity and reliability of the Turkish version of the scale for use in a Turkish population.

Danish emission inventories for road transport and other mobile sources. Inventories until the year 2010

This report explains the parts of the Danish emission inventories related to road transport and other mobile sources. Emission results are shown for CO{sub 2}, CH{sub 4}, N{sub 2}O, SO{sub 2}, NO{sub X}, NMVOC, CO, particulate matter (PM), heavy metals, dioxins and PAH. From 1990-2010 the fuel consumption and CO{sub 2} emissions for road transport increased by 30 %, and CH{sub 4} emissions have decreased by 74 %. A N{sub 2}O emission increase of 29 % is related to the relatively high emissions from older gasoline catalyst cars. The 1985-2010 emission decrease for NO{sub X}, NMVOC, CO and particulates (exhaust only: Size is below PM{sub 2.5}) -52, -84, -81, and -65 %, respectively, due to the introduction of vehicles complying with gradually stricter emission standards. For SO{sub 2} the emission drop 99 % (due to reduced sulphur content in the diesel fuel), whereas the NH{sub 3} emissions increased by 2232 % (due to the introduction of catalyst cars). For other mobile sources the calculated emission changes for CO{sub 2} (and fuel use), CH{sub 4} and N{sub 2}O were -2, 5 and -1 %, from 1990 to 2010. The emissions of SO{sub 2}, particulates (all size fractions), NO{sub X}, NMVOC and CO decreased by 88, 65, 17, 28 and 2 % from 1985 to 2010. For NH{sub 3} the emissions increased by 17 % in the same time period. Uncertainties for the emissions and trends were estimated. (Author)

Fietz, Jennifer; Stupp, Barbara

2018-05-04

Traditional municipal services are not successful at reaching Turkish seniors. Compared to native Germans Turkish seniors have a lower social participation. Do native language groups hosted by a German organization promote the social participation of Turkish seniors? How does social participation take place in the ZWAR networks (between work and retirement; a project to strengthen social participation of seniors) and which factors promote or reduce social participation? Qualitative structuring content analysis of two group discussions, which were based on guided interviews. The social participation of Turkish-speaking seniors was strengthened on three levels: (1) through regular meetings of the Turkish ethnic group social relationships were promoted and German language skills and other skills were improved. Through mutual sharing and understanding of the stressors specific to migration, emotional support was provided. The sharing of mutual cultural and linguistic backgrounds created a sense of community and meetings were perceived as an antidote to migrants' exhausting lives in German society. (2) At the organizational level, participation was promoted through extensive group events. Regardless of their cultural background all participants identified as equal ZWAR members. The ZWAR project functioned as an umbrella organization for participation in the intercultural context. (3) Participation in community events created contacts with community stakeholders and fostered volunteer work. Hence, participants were able to use their skills, and therefore broaden their horizons. Turkish ZWAR networks promoted the social participation of members because integration with their ethnic group reduced access barriers, broadened members' scopes of action, and created new opportunities for participation.

Modelling and forecasting Turkish residential electricity demand

Dilaver, Zafer; Hunt, Lester C

2011-01-01

This research investigates the relationship between Turkish residential electricity consumption, household total final consumption expenditure and residential electricity prices by applying the structural time series model to annual data over the period from 1960 to 2008. Household total final consumption expenditure, real energy prices and an underlying energy demand trend are found to be important drivers of Turkish residential electricity demand with the estimated short run and the long run total final consumption expenditure elasticities being 0.38 and 1.57, respectively, and the estimated short run and long run price elasticities being -0.09 and -0.38, respectively. Moreover, the estimated underlying energy demand trend, (which, as far as is known, has not been investigated before for the Turkish residential sector) should be of some benefit to Turkish decision makers in terms of energy planning. It provides information about the impact of past policies, the influence of technical progress, the impacts of changes in consumer behaviour and the effects of changes in economic structure. Furthermore, based on the estimated equation, and different forecast assumptions, it is predicted that Turkish residential electricity demand will be somewhere between 48 and 80 TWh by 2020 compared to 40 TWh in 2008. - Research highlights: → Estimated short run and long run expenditure elasticities of 0.38 and 1.57, respectively. → Estimated short run and long run price elasticities of -0.09 and -0.38, respectively. → Estimated UEDT has increasing (i.e. energy using) and decreasing (i.e. energy saving) periods. → Predicted Turkish residential electricity demand between 48 and 80 TWh in 2020.

It is well established that GHG emissions must be reduced 50 to 80% by 2050 in order to limit global temperature increase to 2 °C. Achieving reductions of this magnitude in the transportation sector is a challenge and requires a multitude of policies and technology options. The research presented here analyzes three scenarios: changes in the perceived price of travel, land use intensification, and increases in transit. Elasticity estimates are derived using an activity-based travel model for the state of California and broadly representative of the US. The VISION model is used to forecast changes in technology and fuel options that are currently forecast to occur in the US for the period 2000–2040, providing a life-cycle GHG forecast for the road transportation sector. Results suggest that aggressive policy action is required, especially pricing policies, but also more on the technology side, especially increases in the carbon efficiency of medium and heavy-duty vehicles. - Highlights: • Travel elasticities are calculated for policy scenarios using an activity-based travel model. • These elasticities are used to estimate changes in total life-cycle greenhouse gas emissions. • Current technology and fuel policy and the strongest behavioral policy will not meet targets. • Heavy and medium-duty trucks need more aggressive technology and fuel options

Environmental problems attributed due to increased road traffic intensity in Hyderabad city

International Nuclear Information System (INIS)

Memon, Z.; Ansari, A.K.

2001-01-01

Hyderabad is a historical city, so roads are not so wide to cater the present intensity of traffic, hence it is facing transportation problems. No any attempt of traffic management and control has been made in this regard to solve the acute problem of city. Some of the typical problems can be stated as poor driving, encroachments, unsystematic parking on roads, improper road markings and road sings, inadequate road geometry and inadequate control system at intersections etc. This study involves measurement of vehicles flow at five sites of Hyderabad city, and assessment of health hazards on human being due to noise congestion, improper road planning coupled with old city streets converted into roads which are now insufficient for present traffic density, resulting disturbance to pedestrians and dwellers who are living near by road for smooth walk. Motor vehicles, however, play a vital role in the field of public and goods transportation and this survey shows that there are about 726 vehicles operating per hour at the five sites in the city.

Heterogeneity of demand responses in modelling the distributional consequences of tradable carbon permits in the road transport sector

International Nuclear Information System (INIS)

Wadud, Zia; Noland, Robert B.; Graham, Daniel J.

2007-01-01

Personal road transport sector is one of the largest and fastest growing sources of CO 2 emissions. This paper investigates a tradable permit policy for mitigating carbon emissions from personal road transport and discusses various issues of permit allocation. As tradable permits will effectively raise the price of fuel, the policy has important distributional implications. The distribution of burden depends on permit allocation strategies and on the consumer response to an increase in price. The behavioural response may vary among different segments of the population depending on their travel needs, which in turn are contingent upon their income, location of residence and other factors. Consumer Expenditure Survey micro dataset from 1997 to 2002 has been used to econometrically model the possible variation of price elasticity for different socio-economic groups in the USA. Results indicate that the response of gasoline demand to a change in price does depend on income level or location of the household. Distributional impacts of the tradable permit policy are then evaluated using the micro dataset for year 2002. In this regard, different permit allocation schemes are considered in the analysis. Impacts on households owning a vehicle and households with no vehicles have been evaluated as well

2009-07-15

British Columbia's vast network of resource roads are considered to be amongst the most dangerous, high-risk workplaces in the province. Resource roads, also known as industrial roads, forest service roads, or petroleum development roads, present several unique safety challenges as workplaces. They are built for the purpose of access, egress and transport of materials, resources, equipment and people. However, the lack the same diligence of enforcement and a consistent design, construction, maintenance and standard for use as public highways or municipal roads. There are also safety challenges related to public use of resource roads. This report presented a project, called ResourceRoads by WorkSafe BC that focused on the organization and implementation of a management structure that would provide a system of coordination and a process of compliance for the users of the defined road systems. The project was based on information gathered in two forest districts of Prince George and the South Peace Forest Districts. A committee consisting of the actual owner of the road and other users was formed. The report presented a history of British Columbia's resource road system, and discussed resource roads as industrial workplaces and worksites, as well as resource road fatality statistics. The demonstration project was outlined in terms of project leadership; scope; strategic objectives; project purpose; performance objectives; project communication; demonstration areas; and project stages. Project fundamentals and project findings were also presented along with recommendations and responses to the Auditor General report and the Forest Safety Ombudsman report. It was concluded that potential uses of new technologies for resource road vehicles should be reviewed. tabs., figs.

This case study of the Argentina Road Safety Project demonstrates how the application of World Bank road safety project guidelines focused on institution building can accelerate knowledge transfer, scale up investment and improve the focus on results. The case study highlights road safety as a development priority and outlines World Bank initiatives addressing the implementation of the World Report on Road Traffic Injury's recommendations and the subsequent launch of the Decade of Action for Road Safety, from 2011-2020. The case study emphasizes the vital role played by the lead agency in ensuring sustainable road safety improvements and promoting the shift to a 'Safe System' approach, which necessitated the strengthening of all elements of the road safety management system. It summarizes road safety performance and institutional initiatives in Argentina leading up to the preparation and implementation of the project. We describe the project's development objectives, financing arrangements, specific components and investment staging. Finally, we discuss its innovative features and lessons learned, and present a set of supplementary guidelines, both to assist multilateral development banks and their clients with future road safety initiatives, and to encourage better linkages between the health and transportation sectors supporting them.

Assessment of the Electrification of the Road Transport Sector on Net System Emissions

Science.gov (United States)

Miller, James

As worldwide environmental consciousness grows, electric vehicles (EVs) are becoming more common and despite the incredible potential for emissions reduction, the net emissions of the power system supply side plus the transportation system are dependent on the generation matrix. Current EV charging patterns tend to correspond directly with the peak consumption hours and have the potential to increase demand sharply allowing for only a small penetration of Electric Vehicles. Using the National Household Travel Survey (NHTS) data a model is created for vehicle travel patterns using trip chaining. Charging schemes are modeled to include uncontrolled residential, uncontrolled residential/industrial charging, optimized charging and optimized charging with vehicle to grid discharging. A charging profile is then determined based upon the assumption that electric vehicles would directly replace a percentage of standard petroleum-fueled vehicles in a known system. Using the generation profile for the specified region, a unit commitment model is created to establish not only the generation dispatch, but also the net CO2 profile for variable EV penetrations and charging profiles. This model is then used to assess the impact of the electrification of the road transport sector on the system net emissions.

Impact of a future H2-based road transportation sector on the composition and chemistry of the atmosphere - Part 2: Stratospheric ozone

Wang, D.; Jia, W.; Olsen, S. C.; Wuebbles, D. J.; Dubey, M. K.; Rockett, A. A.

2013-07-01

The prospective future adoption of molecular hydrogen (H2) to power the road transportation sector could greatly improve tropospheric air quality but also raises the question of whether the adoption would have adverse effects on the stratospheric ozone. The possibility of undesirable impacts must be fully evaluated to guide future policy decisions. Here we evaluate the possible impact of a future (2050) H2-based road transportation sector on stratospheric composition and chemistry, especially on the stratospheric ozone, with the MOZART (Model for OZone And Related chemical Tracers) model. Since future growth is highly uncertain, we evaluate the impact of two world evolution scenarios, one based on an IPCC (Intergovernmental Panel on Climate Change) high-emitting scenario (A1FI) and the other on an IPCC low-emitting scenario (B1), as well as two technological options: H2 fuel cells and H2 internal combustion engines. We assume a H2 leakage rate of 2.5% and a complete market penetration of H2 vehicles in 2050. The model simulations show that a H2-based road transportation sector would reduce stratospheric ozone concentrations as a result of perturbed catalytic ozone destruction cycles. The magnitude of the impact depends on which growth scenario evolves and which H2 technology option is applied. For the evolution growth scenario, stratospheric ozone decreases more in the H2 fuel cell scenarios than in the H2 internal combustion engine scenarios because of the NOx emissions in the latter case. If the same technological option is applied, the impact is larger in the A1FI emission scenario. The largest impact, a 0.54% decrease in annual average global mean stratospheric column ozone, is found with a H2 fuel cell type road transportation sector in the A1FI scenario; whereas the smallest impact, a 0.04% increase in stratospheric ozone, is found with applications of H2 internal combustion engine vehicles in the B1 scenario. The impacts of the other two scenarios fall

Developing a 3D Road Cadastral System: Comparing Legal Requirements and User Needs

Science.gov (United States)

Gristina, S.; Ellul, C.; Scianna, A.

2016-10-01

Road transport has always played an important role in a country's growth and, in order to manage road networks and ensure a high standard of road performance (e.g. durability, efficiency and safety), both public and private road inventories have been implemented using databases and Geographical Information Systems. They enable registering and managing significant amounts of different road information, but to date do not focus on 3D road information, data integration and interoperability. In an increasingly complex 3D urban environment, and in the age of smart cities, however, applications including intelligent transport systems, mobility and traffic management, road maintenance and safety require digital data infrastructures to manage road data: thus new inventories based on integrated 3D road models (queryable, updateable and shareable on line) are required. This paper outlines the first step towards the implementation of 3D GIS-based road inventories. Focusing on the case study of the "Road Cadastre" (the Italian road inventory as established by law), it investigates current limitations and required improvements, and also compares the required data structure imposed by cadastral legislation with real road users' needs. The study aims to: a) determine whether 3D GIS would improve road cadastre (for better management of data through the complete life-cycle infrastructure projects); b) define a conceptual model for a 3D road cadastre for Italy (whose general principles may be extended also to other countries).

Solutions to Improve Person Transport System in the Pitesti City by Analyzing Public Transport vs. Private Transport

Science.gov (United States)

Mihaela, Istrate; Alexandru, Boroiu; Viorel, Nicolae; Ionel, Vieru

2017-10-01

One of the major problems facing the Pitesti city is the road congestion that occurs in the central area of the city during the peak hours. With all the measures taken in recent years - the widening of road arteries, increasing the number of parking spaces, the creation of overground road passages - it is obvious that the problem can only be solved by a new philosophy regarding urban mobility: it is no longer possible to continue through solutions to increase the accessibility of the central area of the city, but it is necessary, on the contrary, to promote a policy of discouraging the penetration of vehicles in the city center, coupled with a policy of improving the connection between urban public transport and county public transport. This new approach is also proposed in the new Urban Mobility Plan of Pitesti city, under development. The most convincing argument for the necessity of this new orientation in the Pitesti city mobility plan is based on the analysis of the current situation of passenger transport on the territory of Pitesti city: the analysis of “public transport versus private transport” reveals a very low occupancy rate for cars and the fact that the road surface required for a passenger (the dynamic area) is much higher in the case of private transport than in the case of public transport. Measurements of passenger flows and vehicle flows on the 6 penetration ways in the city have been made and the calculations clearly demonstrate the benefits of an urban public transport system connected by “transshipment buses” to be made at the edge of the city, to the county public transport system. In terms of inter-county transport, it will continue to be connected to the urban public transport system by existing bus Station, within the city: South Bus Station and North Bus Station. The usefulness of the paper is that it identifies the solutions for sustainable mobility in Pitesti city and proposes concrete solutions for the development of the

Meso-scale on-road vehicle emission inventory approach: a study on Dhaka City of Bangladesh supporting the 'cause-effect' analysis of the transport system.

Science.gov (United States)

Iqbal, Asif; Allan, Andrew; Zito, Rocco

2016-03-01

The study aims to develop an emission inventory (EI) approach and conduct an inventory for vehicular sources in Dhaka City, Bangladesh. A meso-scale modelling approach was adopted for the inventory; the factors that influence the emissions and the magnitude of emission variation were identified and reported on, which was an innovative approach to account emissions unlike the conventional inventory approaches. Two techniques for the emission inventory were applied, viz. (i) a combined top-down and bottom-up approach that considered the total vehicle population and the average diurnal on-road vehicle speed profile in the city and (ii) a bottom-up approach that accounted for road link-specific emissions of the city considering diurnal traffic volume and speed profiles of the respective roads. For the bottom-up approach, road link-specific detailed data were obtained through field survey in 2012, where mid-block traffic count of the day, vehicle speed profile, road network and congestion data were collected principally. The emission variances for the change in transport system characteristics (like change in fuel type, AC usage pattern, increased speed and reduced congestion/stopping) were predicted and analysed in this study; congestion influenced average speed of the vehicles, and fuel types in the vehicles were identified as the major stressors. The study performance was considered reasonable when comparing with the limited number of similar studies conducted earlier. Given the increasing trend of private vehicles each year coupled with increasing traffic congestion, the city is under threat of increased vehicular emissions unless a good management strategy is implemented. Although the inventory is conducted for Dhaka and the result may be important locally, the approach adopted in this research is innovative in nature to be followed for conducting research on other urban transport systems.

Forest soil erosion prediction as influenced by wildfire and roads

Science.gov (United States)

Cao, L.; Brooks, E. S.; Elliot, W.

2017-12-01

Following a wildfire, the risk of erosion is greatly increased. Forest road networks may change the underlying topography and alter natural flow paths. Flow accumulation and energy can be redistributed by roads and alter soil erosion processes. A LiDAR (Light Detection and Ranging) DEM makes it possible to quantify road topography, and estimate how roads influence surface runoff and sediment transport in a fire-disturbed watershed. With GIS technology and a soil erosion model, this study was carried out to evaluate the effect of roads on erosion and sediment yield following the Emerald Fire southwest of Lake Tahoe. The GeoWEPP model was used to estimate onsite erosion and offsite sediment delivery from each hillslope polygon and channel segment before and after fire disturbance in part of the burned area. The GeoWEPP flow path method was used to estimate the post-fire erosion rate of each GIS pixel. A 2-m resolution LiDAR DEM was used as the terrain layer. The Emerald Fire greatly increased onsite soil loss and sediment yields within the fire boundary. Following the fire, 78.71% of the burned area had predicted sediment yields greater than 4 Mg/ha/yr, compared to the preburn condition when 65.3% of the study area was estimated to generate a sediment yield less than 0.25 Mg/ha/yr. Roads had a remarkable influence on the flow path simulation and sub-catchments delineation, affecting sediment transport process spatially. Road segments acted as barriers that intercepted overland runoff and reduced downslope flow energy accumulation, therefore reducing onsite soil loss downslope of the road. Roads also changed the boundary of sub-catchment and defined new hydrological units. Road segments can transport sediment from one sub-catchment to another. This in turn leads to the redistribution of sediment and alters sediment yield for some sub-catchments. Culverts and road drain systems are of vital importance in rerouting runoff and sediment. Conservation structures can be

A good understanding of the learning styles of students is necessary for optimizing the quality of the learning process. There are few studies in Turkey on the subject of the learning characteristics of medical students. The aim of this study was to define the learning patterns of Turkish medical students based on the Turkish version of Vermunts Inventory of Learning Styles (ILS). The Turkish version of the ILS was developed and administered to 532 medical students. Learning patterns were investigated using factor analysis. Internal consistencies of scales ranged from 0.43 to 0.80. The Turkish version of the ILS identified four learning styles among medical students. In comparing the pre-clinical and clinical phases of medical students related to mental models of learning, statistically significant differences (p learning characteristics: lack of regulation; certificate; self-test and ambivalent orientation; intake of knowledge; and use of knowledge. The Turkish version of the ILS can be used to identify learning styles of medical students. Our findings indicate an intermediate position for our students on a teacher-regulated to student-regulated learning continuum. A variety of teaching methods and learning activities should be provided in medical schools in order to address the range of learning styles.

Road mortality is probably the best-known and visible impact of roads upon wildlife. Although several factors influence road-kill counts, carcass persistence time is considered the most important determinant underlying underestimates of road mortality. The present study aims to describe and model carcass persistence variability on the road for different taxonomic groups under different environmental conditions throughout the year; and also to assess the effect of sampling frequency on the relative variation in road-kill estimates registered within a survey. Daily surveys of road-killed vertebrates were conducted over one year along four road sections with different traffic volumes. Survival analysis was then used to i) describe carcass persistence timings for overall and for specific animal groups; ii) assess optimal sampling designs according to research objectives; and iii) model the influence of road, animal and weather factors on carcass persistence probabilities. Most animal carcasses persisted on the road for the first day only, with some groups disappearing at very high rates. The advisable periodicity of road monitoring that minimizes bias in road mortality estimates is daily monitoring for bats (in the morning) and lizards (in the afternoon), daily monitoring for toads, small birds, small mammals, snakes, salamanders, and lagomorphs; 1 day-interval (alternate days) for large birds, birds of prey, hedgehogs, and freshwater turtles; and 2 day-interval for carnivores. Multiple factors influenced the persistence probabilities of vertebrate carcasses on the road. Overall, the persistence was much lower for small animals, on roads with lower traffic volumes, for carcasses located on road lanes, and during humid conditions and high temperatures during the wet season and dry seasons, respectively. The guidance given here on monitoring frequencies is particularly relevant to provide conservation and transportation agencies with accurate numbers of road

Emission projections of the transport Sector in China: 2015-2040

Science.gov (United States)

Yan, L.

2016-12-01

Driven by the significant growth freight and passenger transport demand, transport sector has become a sector that is largely responsible for increases in emissions of atmospheric pollutants (NOx, CO, HC, PM2.5) in China. Figuring out the emission trend in China's transport sector has great influence on formulating emission reduction measures in the future. In this work, both on-road and off-road transport emissions in China were estimated from 2015 to 2040 for CO, NOx, HC and PM2.5. The projection was conducted based on on the energy consumption structure forecast from IEA (International Energy Agency), the future national average annual distance traveled per vehicle and fuel consumption per distance derived from simulation results of the Fuel Economy and Environmental Impact (FEEI) model. The results show that the ownership of on-road vehicles in China increases rapidly during 2015 to 2030 and then the growth slows down. Finally, the total amount reaches up to 522 million in 2040 in which 84.5% turns out to be light-duty vehicles. Because current control legislations for the transport sector in China will continue to be strengthened in the future, the total emissions of China's transport sector were projected to peak around 2030, due to the improvement of vehicle emission standard and the retirement of old vehicles are the most effective measures. The off-road transport will become the main contributor to emissions from transport sector in China since 2030. This work provides a new perspective to understand emissions from both on-road and off-road transport in China, which can support the achievement of improving air quality promised by the Chinese government. This work provides a new perspective to understand the emission trends of on-road and off-road transport sector in China from 2015 to 2040, which can support the achievement of the air quality goal promised by the Chinese government.

Clinical bracket points were calculated for each tooth based on mandibular tooth thickness data. Four linear and two proportional measurements were taken. The subjects were grouped according to arch form types (tapered, ovoid and square in order to have frequency distribution compared between ethnic groups in each Angle classification. Results: The Turkish group showed significantly lower molar depth and more significant molar width-depth (W/D ratio in all three Angle classifications. On the other hand, the Turkish group also showed a significantly larger intercanine width in Class III malocclusion and intermolar width in Class II malocclusion. The most frequent arch forms seen were the ovoid arch form in the Turkish group and the tapered form in the white group. Conclusions: Our results demonstrate that when treating Turkish patients, one should expect to use preformed ovoid arch form orthodontic wires in a significant percentage of patients.

Full Text Available The Great Silk Road (GSR called so in the late 19th century by German geographer Ferdinand von Richthofen started shaping in the 2nd century B.C. In the minds of peoples the Silk Road is a generalized symbol of trade caravan routes crossing Central Asia, connecting until the 16th century the Far East, in particular Japan, China, with Middle Asia. Appearance in the early 21st century of new independent states in Central Asia along the GSR route was a powerful impetus for revival of the ancient trade route. In September 2013 Xi Jinping, President of the People's Republic of China, during his visit to the Central Asian countries offered the strategic concept of joint construction of the “economic corridor along the Silk Road” based on innovative cooperation in order to revive and consolidate the economic contacts among the Eurasian countries. Establishment of the modern analog of GSR, a powerful transport and pipeline corridor includes the integrated system of railroads and automobile roads, oil and gas pipelines, airlines, and sea lines.

between Turkish newcomers and various Turkic-speaking groups in the area both create different and overlapping “ecumenical communities” and actualize long-forgotten connections or marginal historical visions. These migrants also generate important links to the area through marriage and intimate relations...... with Slav women. I argue that alliances between Turkish migrants and Turkic-speaking minorities and local women not only allow them to make the city their own, but also create a distance from wider Odessan society....

Modelling of road traffic fatalities in India.

Goel, Rahul

2018-03-01

Passenger modes in India include walking, cycling, buses, trains, intermediate public transport modes (IPT) such as three-wheeled auto rickshaws or tuk-tuks, motorised two-wheelers (2W) as well as cars. However, epidemiological studies of traffic crashes in India have been limited in their approach to account for the exposure of these road users. In 2011, for the first time, census in India reported travel distance and mode of travel for workers. A Poisson-lognormal mixture regression model is developed at the state level to explore the relationship of road deaths of all the road users with commute travel distance by different on-road modes. The model controlled for diesel consumption (proxy for freight traffic), length of national highways, proportion of population in urban areas, and built-up population density. The results show that walking, cycling and, interestingly, IPT are associated with lower risk of road deaths, while 2W, car and bus are associated with higher risk. Promotion of IPT has twofold benefits of increasing safety as well as providing a sustainable mode of transport. The mode shift scenarios show that, for similar mode shift across the states, the resulting trends in road deaths are highly dependent on the baseline mode shares. The most worrying trend is the steep growth of death burden resulting from mode shift of walking and cycling to 2W. While the paper illustrates a limited set of mode shift scenarios involving two modes at a time, the model can be applied to assess safety impacts resulting from a more complex set of scenarios.

Safe of transportation on road is global problem with not only transportation problem, but also social teritory problem in sosial life. WHO pay attention to safe transportation on road to decide healthy day in the world 2004 with caption: Road Safety is no Accident. WHO is clariafy that road accident level in the world have to reach 1.2 mellion victim death and over 30 mellion injuries every year. As much 85% sacrifice death are accident in develop state, where vehicle number only 32% from vehicle number in the world. That becouse as the objective is to decide influence road charakteristics geometrics for motorcycle accident in Batu East Java Indonesia. Using some statistical analysis it is found that the best-fit motorcycle accident model is: Acc = 0,009F0,703exp(-0,334SW-0,361G+0.077S) Where: Acc = number of accident, F = Flow, pcu/hr, SW = shoulder width (m), S = speed, km/hr, G = Gradient (0,1) The model shows that the affecting factors are flow, shoulder width and speed, therefore local government should improve some related factor (flow, shoulder width, Gradient and speed) that can reduce the number of motorcycle accident at crossing road in Batu.

The Production of Turkish Relative Clauses in Second Language Acquisition: Overcoming Student Difficulties

Full Text Available This study focuses on teaching relative clauses (R.Cs in Turkish, a left-branching language, and discusses the relative difficulty of producing RCs in Turkish by English-speaking learners by investigating whether the production of subject relative clauses in Turkish is easier than that of the object relative clauses. It also offers suggestions as to how to help learners overcome these difficulties. Turkish and English belong to two different language families, Altaic and Inda-European respectively. This study lends further insight that Turkish does not have RCs similar to those found in Inda-European languages. Instead, in Turkish RCs comprise nominalized verbs and participles. The characteristics of Turkish are also explained such as its word order, agglutinating morphology, vowel and consonant harmony rules as well as case markers indicating grammatical relations between sentence constituents, which shed light to our understanding of RCs in Turkish. Data was collected through written and oral tasks from students enrolled in a military intensive Turkish language training program in the United States. Moreover, their performance was studied through classroom observations and one-on-one speaking activities.

Several theories have sought to explain the motivations for handgun possession and the relationship with personality. Perception of handguns also has cultural variations. The aim of the study is to evaluate handgun license applicants' personality profiles. 109 handgun license applicants were included in the study. Temperament and Character Inventory (TCI) scores of the applicants were recorded. Scores were compared with Turkish and American normative data for the Inventory. The study group had significantly lower subscores on novelty seeking, harm avoidance, and higher subscores on reward dependence and persistence compared to Turkish norms and significantly lower subscores on novelty seeking, reward dependence, and self-directedness compared to American norms. Results indicate that Turkish handgun license applicants' personality features are more similar to American norms.

The Potential of Road Pricing Schemes for Reducing Carbon Emissions

Energy Technology Data Exchange (ETDEWEB)

Nocera, S.; Giaretta, F.; Cavallaro, F.

2016-07-01

Road pricing is a transport measure mainly conceived to fund road management, to regulate the demand for traffic and to reduce the number of private vehicles circulating in urban areas. It can also grant benefits in terms of environmental externalities including the reduction of CO2 emissions, which has recently become one of the most important elements defining the sustainability of a transport system. However, the carbon potential granted by road charging is rarely assessed, thus confirming a sort of secondary role attributed to CO2 in urban premises. This paper provides an accurate analysis of the relationship between the different forms of road pricing (including distance-based, congestion-based and pay-as-you-drive) and their effective role in terms of carbon reduction, which in some contexts is higher than 10%. Furthermore, practical suggestions to policy makers in terms of implementation of the measure are discussed, highlighting the precautions necessary to include a fair carbon evaluation into an overall effective analysis.

Placarding of road vehicles carrying radioactive materials

International Nuclear Information System (INIS)

1977-09-01

The purpose of this Code is to give guidance on the placarding requirements for vehicles carrying radioactive materials by road in Great Britain and on the continent of Europe. Additional placards may be required regarding dangerous properties other than radioactivity. The labelling of packages for transport is dealt with in AECP 1030. This Code deals with two aspects of road vehicle placarding:-(a) placarding on the outside of road vehicles in Great Britain and on the continent of Europe, (b) a fireproof placard fixed in the driver's cab. Responsibility for placarding the vehicle rests with the carrier, but in practice the consignor may need to provide the placards. (U.K.)

Laraia Barbara A

2009-05-01

Full Text Available Abstract Background Health researchers have increasingly adopted the use of geographic information systems (GIS for analyzing environments in which people live and how those environments affect health. One aspect of this research that is often overlooked is the quality and detail of the road data and whether or not it is appropriate for the scale of analysis. Many readily available road datasets, both public domain and commercial, contain positional errors or generalizations that may not be compatible with highly accurate geospatial locations. This study examined the accuracy, completeness, and currency of four readily available public and commercial sources for road data (North Carolina Department of Transportation, StreetMap Pro, TIGER/Line 2000, TIGER/Line 2007 relative to a custom road dataset which we developed and used for comparison. Methods and Results A custom road network dataset was developed to examine associations between health behaviors and the environment among pregnant and postpartum women living in central North Carolina in the United States. Three analytical measures were developed to assess the comparative accuracy and utility of four publicly and commercially available road datasets and the custom dataset in relation to participants' residential locations over three time periods. The exclusion of road segments and positional errors in the four comparison road datasets resulted in between 5.9% and 64.4% of respondents lying farther than 15.24 meters from their nearest road, the distance of the threshold set by the project to facilitate spatial analysis. Agreement, using a Pearson's correlation coefficient, between the customized road dataset and the four comparison road datasets ranged from 0.01 to 0.82. Conclusion This study demonstrates the importance of examining available road datasets and assessing their completeness, accuracy, and currency for their particular study area. This paper serves as an example for assessing

Impact of a future H2-based road transportation sector on the composition and chemistry of the atmosphere – Part 2: Stratospheric ozone

Directory of Open Access Journals (Sweden)

D. Wang

2013-07-01

Full Text Available The prospective future adoption of molecular hydrogen (H2 to power the road transportation sector could greatly improve tropospheric air quality but also raises the question of whether the adoption would have adverse effects on the stratospheric ozone. The possibility of undesirable impacts must be fully evaluated to guide future policy decisions. Here we evaluate the possible impact of a future (2050 H2-based road transportation sector on stratospheric composition and chemistry, especially on the stratospheric ozone, with the MOZART (Model for OZone And Related chemical Tracers model. Since future growth is highly uncertain, we evaluate the impact of two world evolution scenarios, one based on an IPCC (Intergovernmental Panel on Climate Change high-emitting scenario (A1FI and the other on an IPCC low-emitting scenario (B1, as well as two technological options: H2 fuel cells and H2 internal combustion engines. We assume a H2 leakage rate of 2.5% and a complete market penetration of H2 vehicles in 2050. The model simulations show that a H2-based road transportation sector would reduce stratospheric ozone concentrations as a result of perturbed catalytic ozone destruction cycles. The magnitude of the impact depends on which growth scenario evolves and which H2 technology option is applied. For the evolution growth scenario, stratospheric ozone decreases more in the H2 fuel cell scenarios than in the H2 internal combustion engine scenarios because of the NOx emissions in the latter case. If the same technological option is applied, the impact is larger in the A1FI emission scenario. The largest impact, a 0.54% decrease in annual average global mean stratospheric column ozone, is found with a H2 fuel cell type road transportation sector in the A1FI scenario; whereas the smallest impact, a 0.04% increase in stratospheric ozone, is found with applications of H2 internal combustion engine vehicles in the B1 scenario. The impacts of the other two

Fábio Silva

2014-12-01

Full Text Available Road traffic is a problem which is increasing in cities with large population. Unrelated to this fact the number of portable and wearable devices has also been increasing throughout the population of most countries. With this advent, the capacity to monitor and register data about people habits and locations as well as more complex data such as intensity and strength of movements has created an opportunity to contribute to the general wealth and comfort within these environments. Ambient Intelligence and Intelligent Decision Making processes can benefit from the knowledge gathered by these devices to improve decisions on everyday tasks such as deciding navigation routes by car, bicycle or other means of transportation and avoiding route perils. The concept of computational sustainability may also be applied to this problem. Current applications in this area demonstrate the usefulness of real time system that inform the user of certain conditions in the surrounding area. On the other hand, the approach presented in this work aims to describe models and approaches to automatically identify current states of traffic inside cities and use methods from computer science to improve overall comfort and the sustainability of road traffic both with the user and the environment in mind. Such objective is delivered by analyzing real time contributions from those mobile ubiquitous devices to identifying problematic situations and areas under a defined criteria that have significant influence towards a sustainable use of the road transport infrastructure.

Road Network Vulnerability Analysis Based on Improved Ant Colony Algorithm

Directory of Open Access Journals (Sweden)

Yunpeng Wang

2014-01-01

Full Text Available We present an improved ant colony algorithm-based approach to assess the vulnerability of a road network and identify the critical infrastructures. This approach improves computational efficiency and allows for its applications in large-scale road networks. This research involves defining the vulnerability conception, modeling the traffic utility index and the vulnerability of the road network, and identifying the critical infrastructures of the road network. We apply the approach to a simple test road network and a real road network to verify the methodology. The results show that vulnerability is directly related to traffic demand and increases significantly when the demand approaches capacity. The proposed approach reduces the computational burden and may be applied in large-scale road network analysis. It can be used as a decision-supporting tool for identifying critical infrastructures in transportation planning and management.

Full Text Available Abstract This article presents the adaptation and psychometric evaluation of the Turkish version of Harmony in Life Scale (Turkish-HiL. The present paper investigates (study 1; N 1 = 253 confirmatory factor analysis, measurement invariance; (study 2; N 2 = 231 concurrent validity; (study 3; N 3 = 260 convergent and known-group validities; (study 4; N t − t = 50 test-retest, Cronbach alpha, and composite reliabilities of the Turkish-HiL. In study 1, based on a confirmatory factor analysis, results confirmed that unidimensional-factor structure. The results suggested that the model demonstrated a configural and metric invariance across the gender groups. In study 2, Turkish-HiL significantly correlated with measures of satisfaction with life, subjective happiness, positive affect, and negative affect. In study 3, Turkish-HiL was predicted positively by flourishing, conversely, negatively predicted by depression, anxiety, and stress. Finally, in study 4, alpha, composite and test-retest reliabilities are acceptable. Overall, the scale presented here may prove useful for satisfactorily assessing, in Turkish, the harmony in life of the university students.

INTERMODAL TRANSPORT IN EUROPE - OPPORTUNITIES THROUGH INNOVATION

Directory of Open Access Journals (Sweden)

Norbert Wagener

2014-12-01

Full Text Available Background: Freight transport volume in ton-km in OECD countries will grow considerably up to 150 to 230 % in 2050 compared to 2010. Although the EU policy aims to shift 30% of road freight over 300 km to other modes such as rail or waterborne transport by 2030 the recent trends show a stable modal split of road at approx. 75%. Conventional intermodal transport on the major European routes has shown a steady but only limited organic growth through recent years. Therefore, new innovative concepts for intermodal transport and for the shift from road to rail are needed. Methods: Definitions of intermodal transport have been clarified and the development of combined transport in Europe and in Germany and Poland in particular has been analyzed on the basis of available data sources. New innovative concepts for intermodal transport have been identified on the basis of desk research, recent relevant projects (RETRACK, SCANDRIA, Rail Baltica and market intelligence. Results: The analysis leads to the conclusion that new innovative concepts in intermodal transport comprise new forms of organization as well as new technologies and new routes. The following three innovations to facilitate the shift from road to rail by intermodal transport are being introduced and discussed: multimodal operation of ocean carriers in maritime hinterland transportation, innovative handling technologies for non-crane able trainers and freight corridors for long distance intermodal transport within the TEN-T network and on the Europe-Asia corridor. Conclusions: Further accelerated growth in the shift from road to rail through intermodal transport requires new innovative concepts beyond the traditional combined transport in Western Europe. Three promising innovative concepts have been introduced. Further research is needed and should be focused on financial and economic appraisal as well as on the effectiveness of state intervention policies.
