    Full Text Available The fundamental aims of sustainable urban development and the pro-automobile oriented economic development are on a collision course. It is obvious that automobile-dependent urban development is under heavy/powerful influence of the automobile lobby (automobile and oil industries, along with construction. In this domain famous land-use-transportation studies (or ‘grand transportation studies’ are, unfortunately, still prevailing - a vicious circle of self-fulfilling prophecy of congestion, road building, sprawl, congestion and more road building. Until recently, it was commonly thought that investment in public transport was not economically sustainable and that focusing on the development of the automobile industry and financing the construction of roadways stimulated economic growth. In this paper we clearly show that automobile industry is now overcapitalized, less profitable than many other industries (and may become even less profitable in the future, that transport market is characterized with huge distortions (more than a third of motor-vehicle use can be explained by underpriced driving, while new road investment does not have a major impact on economic growth (especially in a region with an already well-developed infrastructure, and that pro-automobile transport strategy inexorably incurs harmful global, regional and local ecological consequences.

  3. SUSTAINABLE TRANSPORTATION

    2007-01-01

    Full Text Available This paper discusses possible contributions of psychologists to sustainable transportation. It is argued that in order to reach sustainable transportation, among others, behaviour changes of individual car users are needed. As transport policies will be more effective if they target important antecedents of travel behaviour, first, factors influencing such behaviour are discussed. It is argued that car use is very attractive and sometimes even necessary for many different reasons. This implies that a combination of policies is called for, each targeting different factors that support car use and hinder the use of more sustainable modes of transport. Next, the paper elaborates on policy strategies that may be employed to achieve sustainable transportation by changing car use. Increasing the attractiveness of sustainable transport modes by means of pull measures seems not sufficient to reduce the level of car use. Besides, car use should be made less attractive by means of push measures to force drivers to reconsider their travel behaviour. The acceptability of such policies may be increased by clearly communicating the aim of these policies, and the expected positive consequences (e.g., less congestion, improved environmental quality. Moreover, possible negative effects for individual freedom may be compensated by implementing additional policies aimed at facilitating the use of sustainable transport modes.

  4. Globalization of the automobile industry in China. Dynamics and barriers in the greening of road transportation

    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.

    2017-04-01

    The purpose of this study is to investigate weather and climate conditions of functioning automobile transport in Moscow region. For this, statistics on the daily number of accidents in the City of Moscow in 2013-2014 were studied and compared with the weather conditions. Various weather phenomena and meteorological parameters that affect the increase and decrease in the number of accidents in warm and cold seasons were identified; the extent of this influence was assessed. Moreover, an analysis of the distribution and change of the frequency of occurrence of these phenomena and meteorological parameters in 1961-2010 in Moscow region was conducted. In the cold season, there are much more weather events influencing the growth in the number of accidents than in the warm season. Fallout of more than 2 cm of snow per date, the reduction in meteorological visibility, drizzle and snow storms lead to an increase of accident rate by 5-15%. In the warm season, when thunderstorms and heavy rainfall there is a decrease in accidents; increase in the number of accidents happens in hot weather (maximum air temperatures over +30 °C). In the period 1991-2010 compared to 1961-1990 in the Moscow oblast the sustained cold period and amount of precipitation under negative air temperature has reduced; a decrease in the number of days with reduced visibility range and the offset of the date of the fallout of the first snow aside winter months is observed, which is favorable for automobile transport. At the same time, there is an increase in the number of days with transitions of air temperature through 0 °C, and the number of hot days, which negatively affects the functioning automobile transport.

  6. Social Sustainability Issues and Older Adults’ Dependence on Automobiles in Low-Density Environments

    Directory of Open Access Journals (Sweden)

    Hitomi Nakanishi

    2015-06-01

    Full Text Available An implicit assumption underlying government strategies to achieve a more sustainable urban transportation system is that all automobile users will be encouraged or persuaded to use more “green” transportation: public transportation, walking and cycling. Little consideration has been given as to how sustainable transportation policies and programmess might impact on different age groups in society, including those retired or semi-retired, despite the fact that an unprecedented number of older drivers will be on the highways in the next few decades. There is limited literature on the contextual factors behind their continued reliance on automobiles, their actual driving behavior (e.g., route choice and time of day to drive framed within the context of social sustainability. This paper introduces the elements of transportation and social sustainability then conducts a comprehensive international literature review focusing on older drivers, their travel choices and associated social sustainability issues. It describes a case study, low-density city and presents empirical evidence, from two surveys conducted in Canberra, Australia. The paper concludes with future research directions that address these issues associated with sustainable transportation.

    In the paper the following topics are discussed: - the need for public education and involvement in the decision process, - the difficulty of defining sustainability, - the occasional difference between the goals of sustainability and environmental quality, - the need for life cycle analysis to analyze the sustainability and environmental quality implications of a product, process, or material. The importance of environmental input-output analysis is stressed. This new tool can provide the life cycle information cheaply, quickly, and with much less uncertainty. Examples are presented for making an automobile, a seat out of plastic or aluminium, and an electric vehicle. (author) 4 tabs., refs.

    Metropolitan transportation and land development patterns in most of the world are growing increasingly unsustainable. Many factors point to the need for adoption of a new paradigm for sustainable transportation and community development in both high and low income countries: overpopulation, growing air pollution, limited physical and economic capacity to expand automobile-based transportation systems without community destruction, growing inequality in the distribution of resources, and the urgent need to limit global CO{sub 2} emissions to slow the place of global warming. This paper discusses the new paradigm for integrated and sustainable transport strategies. (author) 9 refs.

  15. From Rail-Oriented to Automobile-Oriented Urban Development and Back. 100 Years of Paradigm Change and Transport Policy in Berlin

    Directory of Open Access Journals (Sweden)

    Friedemann Kunst

    2016-10-01

    Full Text Available Transport and its side effects are major problems in rapidly growing cities. Car traffic dominates these cities and pollutes the environment without being able to sufficiently secure the mobility of the urban population and goods. A paradigm shift in urban and transport policy will be necessary to change this situation. In spite of its different development dynamics, Berlin is an interesting example to discuss development strategies for rapidly growing cities because in the course of more than 100 years, a twofold paradigm shift has occurred in the city both conceptually and practically:  Berlin has shifted from a city dominated by rail traffic  to an automobile-oriented city,  and has then gradually transformed back into a city in which  an intertwined system of public and non-motorized individual means of transport secures the mobility of the urban population. The interdependencies on the conceptual level between urban planning and transport policies as well as on a practical level between urban structures and transport systems can be studied using the example of Berlin. Experiences with the implementation of automobile-oriented planning and the special conditions in the first decade after reunification led to protests, reflection, and a revision of the transport policy. A strategically designed process of integrated planning has brought about a trend reversal, and steered the development of transport in the direction of clearly formulated sustainability-oriented objectives. In this process, the reintegration of transport and spatial planning and a reorganization of institutional structures at the administrative level was of particular importance. Compact, rail-oriented settlement structures like in the metropolitan region of Berlin make it easier to dispense with automobiles than sprawled structures. The residual role that qualitatively improved automobiles will take in the cities of the future will have to be determined by research and

    Zhang, Junyi

    2013-01-01

    This book aims to provide a good understanding of and perspective on sustainable transport in Asia by focusing on economic, environmental, and social sustainability. It is widely acknowledged that the current situation and trends in transport are not always sustainable in Asia, due in part to the fast-growing economy and the astounding speed of urbanization as well as least-mature governance. As essential research material, the book provides strong support for policy makers and planners by comprehensively covering three groups of strategies, characterized by the words “avoid” (e.g., urban form design and control of car ownership), “shift” (e.g., establishing comprehensive transportation systems and increasing public transportation systems for both intracity and intercity travel), and “improve” (e.g., redesign of paratransit system, low-emission vehicles, intelligent transportation systems, and eco-life). These are elaborated in the book alongside consideration of the uncertainty of policy effects ...

    Darjeeling is an important tourist hill town of West Bengal, India. It suffers from an acute problem of transportation, particularly during its peak tourist seasons due to limited road space, inadequate public transport facilities and indiscriminate use of automobiles. This hill town was originally designed for a population of 10,000, but over the years, it has come face-to-face with rapid urbanization, a rising population of both tourists and residents and intensifying motor vehicle usage. These factors together are posing a threat to its transport environment. This study identifies the Sustainable Transport Indicators (STIs) available in the existing literature to identify the critical stretches using Analytical Hierarchy Process (AHP) based on experts' consensus. It was found that the experts placed emphasis on the mobility of the town, talking about vehicular impact on air pollution and encroachment of roads as the main issues affecting the sustainability of the transport environment. Thereafter, policy-level interventions have been suggested in accordance with the identified sustainability issues. We trust that other tourist hill towns with issues similar to Darjeeling could easily emulate the study methodology to assess their transport environment sustainability, or replicate on the lines of the recommended policy interventions.

  12. Infrastructure and automobile shifts: positioning transit to reduce life-cycle environmental impacts for urban sustainability goals

    Chester, Mikhail; Pincetl, Stephanie; Elizabeth, Zoe; Eisenstein, William; Matute, Juan

    2013-03-01

    Public transportation systems are often part of strategies to reduce urban environmental impacts from passenger transportation, yet comprehensive energy and environmental life-cycle measures, including upfront infrastructure effects and indirect and supply chain processes, are rarely considered. Using the new bus rapid transit and light rail lines in Los Angeles, near-term and long-term life-cycle impact assessments are developed, including consideration of reduced automobile travel. Energy consumption and emissions of greenhouse gases and criteria pollutants are assessed, as well the potential for smog and respiratory impacts. Results show that life-cycle infrastructure, vehicle, and energy production components significantly increase the footprint of each mode (by 48-100% for energy and greenhouse gases, and up to 6200% for environmental impacts), and emerging technologies and renewable electricity standards will significantly reduce impacts. Life-cycle results are identified as either local (in Los Angeles) or remote, and show how the decision to build and operate a transit system in a city produces environmental impacts far outside of geopolitical boundaries. Ensuring shifts of between 20-30% of transit riders from automobiles will result in passenger transportation greenhouse gas reductions for the city, and the larger the shift, the quicker the payback, which should be considered for time-specific environmental goals.

    2016-04-01

    Full Text Available The Japanese automobile industry has been hit sharply by the economic downturn of recent decades. The rise in costs and decline in sales have led to serious problems in the auto industry. In order to address these issues, most companies engage in downsizing and redesigning production operations. It is crucial to investigate the time wasted by replacing assembly boards occurring in manufacturing lines. Therefore, the aim of this study was to provide an integrated approach, Teoriya Resheniya Izobreatatelskih Zadatch (TRIZ, to providing efficient solutions for the automobile industry. The first step of this methodology is to detail the technical problems using the Function and Attribute Analysis (FAA model. Secondly, a contradiction matrix and the inventive principle were applied to find the solutions. In this study, an auto part supplier named Sumi-Hanel located in Hanoi, Vietnam, was taken as a case study; the empirical results showed that waste time had been reduced to 67%, nearly 8400 square meters was saved, and a 20% cost reduction was achieved by reusing old frames. The research proves that the combination of TRIZ and lean manufacturing successfully increases production performance and reduces waste due to technological advancements.

    Since most modes of transportation rely on liquid energy carriers like gasoline or diesel, the approaching end of the fossil fuel era poses a special challenge. One should bear in mind that nothing matches the energy density of liquid fuels. It is, therefore, important to consider the efficiency of various modes of transportation and explore alternative options for energy carriers. This includes a feasibility study of the use of solar energy in transportation. In this perspective various modes of transportation are briefly reviewed and the possible alternative energy carriers assessed.

  1. Integrating Norm Activation Model and Theory of Planned Behavior to Understand Sustainable Transport Behavior: Evidence from China

    Directory of Open Access Journals (Sweden)

    Yuwei Liu

    2017-12-01

    Full Text Available With increasing urbanization in China, many cities are facing serious environmental problems due to continuous and substantial increase in automobile transportation. It is becoming imperative to examine effective ways to reduce individual automobile use to facilitate sustainable transportation behavior. Empirical, theory-based research on sustainable transportation in China is limited. In this research, we propose an integrated model based on the norm activation model and the theory of planned behavior by combining normative and rational factors to predict individuals’ intention to reduce car use. Data from a survey of 600 car drivers in China’s three metropolitan areas was used to test the proposed model and hypotheses. Results showed that three variables, perceived norm of car-transport reduction, attitude towards reduction, and perceived behavior control over car-transport reduction, significantly affected the intention to reduce car-transport. Personal norms mediated the relationship between awareness of consequences of car-transport, ascription of responsibility of car-transport, perceived subjective norm for car-transport reduction, and intention to reduce car-transport. The results of this research not only contribute to theory development in the area of sustainable transportation behavior, but also provide a theoretical frame of reference for relevant policy-makers in urban transport management.

  5. Achieving deep cuts in the carbon intensity of U.S. automobile transportation by 2050: complementary roles for electricity and biofuels.

    Passenger cars in the United States (U.S.) rely primarily on petroleum-derived fuels and contribute the majority of U.S. transportation-related greenhouse gas (GHG) emissions. Electricity and biofuels are two promising alternatives for reducing both the carbon intensity of automotive transportation and U.S. reliance on imported oil. However, as standalone solutions, the biofuels option is limited by land availability and the electricity option is limited by market adoption rates and technical challenges. This paper explores potential GHG emissions reductions attainable in the United States through 2050 with a county-level scenario analysis that combines ambitious plug-in hybrid electric vehicle (PHEV) adoption rates with scale-up of cellulosic ethanol production. With PHEVs achieving a 58% share of the passenger car fleet by 2050, phasing out most corn ethanol and limiting cellulosic ethanol feedstocks to sustainably produced crop residues and dedicated crops, we project that the United States could supply the liquid fuels needed for the automobile fleet with an average blend of 80% ethanol (by volume) and 20% gasoline. If electricity for PHEV charging could be supplied by a combination of renewables and natural-gas combined-cycle power plants, the carbon intensity of automotive transport would be 79 g CO2e per vehicle-kilometer traveled, a 71% reduction relative to 2013.

    The primary goal of the workshop was to share experiences of sustainable transport practices from invited medium-sized cities in Latin America and Asia. The purpose was to learn how sustainable mechanisms have been incorporated into national planning and implementation systems. Emphasis was given to understand what concrete mechanism work to promote sustainable transport in the selected projects. The workshop included participation of transport economics and engineers, policy makers and policy-advisors, and key representatives from the transportation government and non-governmental sector in El Salvador. Among participants there were also members from academia, private consultants and international NGOs. The workshop provided a basis for outreach in terms of directly informing participants on the specific experiences brought in by the participating countries. The Workshop set out to address the following main objectives: To demonstrate successful examples of transportation initiatives that show positive sustainable economic, environmental and social benefits in selected developing countries; To provide a forum for discussion of sustainable transport paths; To develop a network for information exchange and capacity building; To gather information on concrete mechanisms to promote sustainable transportation; To demonstrate efficient mechanisms and tools for collection and analysis of data in transport; To create an inventory of success stories and alternative visions for the future. Several institutions collaborated in organising the event: the Intermediate Technology Development Group (ITDG-Sri Lanka), The Peace and Development Research Group from Goeteborg University and institutions within El Salvador: Centro Salvadeoreno de Tecnologia Apropiada (CESTA), and the Climate Change Communication office of the Ministry of Environment in Salvador.

    The urban transportation sector’s environmental, economic, and social footprint is immense and expanding. Many of the world’s most vexing and pressing problems – fossil fuel dependency, global warming, poverty, and social exclusion – are inextricably tied to the transportation sector. Much of the blame for the transportation sector’s inordinate environmental footprint lies in the increasing automobile-dependency of cities. Rapid motorization unavoidably shifts future travel from the most sust...

  8. In search of sustainable transport systems

    Several options can be envisaged in order to alleviate the external costs of modern transport systems: moral conviction, strict regulations (including enforcement), user charge principles (e.g. road pricing, Pigovian taxation), sophisticated environment-friendly technologies (e.g. route guidance, zero-emission cars) and alternative modes of physical planning (e.g. compact city design). Any reduction target in environmental stress has to be assessed from both an environmental sustainability viewpoint and from a cost effectiveness viewpoint. Such an assessment may be based on evaluation criteria that are internal to the transport system or on criteria that mirror an overall systemic efficiency and sustainability. This provokes the question of the most appropriate level of reduction of environmental pollution by the transport sector compared to other economic sectors. A policy strategy aiming at a more sustainable transport system has to identify quantitative criteria which would offer guidelines on the maximum allowable contribution to environmental degradation by the transport sector. This presupposes knowledge on the total permissible pollution in a given area and in a given time frame, as well as knowledge on the share of the transport system in this total volume of pollution (for different pollutants). The aim of this paper is to develop some thoughts on the question of identifying the maximum allowable pollution share by the transport sector, assuming a critical level of maximum resource use, a maximum carrying capacity, a maximum environmental utilisation space, a maximum sustainable yield or some other critical threshold level for environmental decay. The notion of maximum environmental capacity use (MECU) is used to indicate the maximum resource use of a given environmental capital stock that - in a given time period - is compatible with both socio-economic objectives and environmental quality conditions now and in the future. 6 tabs., 24 refs.

    Full Text Available Sustainability is a term used more often lately, based on three factors: social, economic, and environmental. Sustainable transport systems increase social cohesion, reduce environmental problems and help create a more efficient economy. Sustainable transport consists in a complex system that is designed to ensure mobility needs of present generations without damaging the environment and health factors. By improving energy and material consumption, it must be capable to satisfy in optimum conditions the need for mobility for future generations. The current transportation system has not a character of sustainability.

    2008-01-01

    Full Text Available The 20th century witnessed revolutionary developments in transportation technology with major impacts on the form and character of cities. Progress in increasing mobility has brought many benefits as well as serious problems, particularly in deterioration of livability and sustainability. Increase in auto ownership led to serious problems of chronic traffic congestion. Attempts to rebuild cities to provide full accommodation of private cars have led to serious problems of auto dependency and deterioration of cities. Experiences from recent decades have shown that urban transportation is much more complex than usually realized. Livable and sustainable cities require policies that lead to creation of a transportation system consisting of coordinated public transit and private cars, and encourages pedestrian environment and efficient, sustainable development. Great need for better understanding of the complex problems in implementing incentives and disincentives aimed at achieving intermodal balance is emphasized. Brief descriptions of cities which lead in achieving such livable conditions is followed by a summary of lessons and guidelines for the future.

  20. Life cycle assessment in support of sustainable transportation

    Science.gov (United States)

    Eckelman, Matthew J.

    2013-06-01

    In our rapidly urbanizing world, sustainable transportation presents a major challenge. Transportation decisions have considerable direct impacts on urban society, both positive and negative, for example through changes in transit times and economic productivity, urban connectivity, tailpipe emissions and attendant air quality concerns, traffic accidents, and noise pollution. Much research has been dedicated to quantifying these direct impacts for various transportation modes. Transportation planning decisions also result in a variety of indirect environmental and human health impacts, a portion of which can accrue outside of the transit service area and so outside of the local decision-making process. Integrated modeling of direct and indirect impacts over the life cycle of different transportation modes provides decision support that is more comprehensive and less prone to triggering unintended consequences than a sole focus on direct tailpipe emissions. The recent work of Chester et al (2013) in this journal makes important contributions to this research by examining the environmental implications of introducing bus rapid transit and light rail in Los Angeles using life cycle assessment (LCA). Transport in the LA region is dominated by automobile trips, and the authors show that potential shifts to either bus or train modes would reduce energy use and emissions of criteria air pollutants, on an average passenger mile travelled basis. This work compares not just the use of each vehicle, but also upstream impacts from its manufacturing and maintenance, as well as the construction and maintenance of the entire infrastructure required for each mode. Previous work by the lead author (Chester and Horvath 2009), has shown that these non-operational sources and largely non-local can dominate life cycle impacts from transportation, again on an average (or attributional) basis, for example increasing rail-related GHG emissions by >150% over just operational emissions

    Full Text Available Introduced autonomous and connected vehicles equipped with emerging technologies are expected to change the automotive market. In this study, using stated preference (SP data collected from choice experiments conducted in Korea with a mixed multiple discrete-continuous extreme value model (MDCEV, we analyzed how the advent of next-generation of vehicles with advanced vehicle technologies would affect consumer vehicle choices and usage patterns. Additionally, ex-ante market simulations and market segmentation analyses were conducted to provide specific management strategies for next-generation vehicles. The results showed that consumer preference structures of conventional and alternative fuel types primarily differed depending on whether they were drivers or non-drivers. Additionally, although the introduction of electric vehicles to the automobile market is expected to negatively affect the choice probability and mileage of other vehicles, it could have a positive influence on the probability of purchasing an existing conventional vehicle if advanced vehicle technologies are available.

    2003-06-01

    This paper outlines several broad actions that the Organizing Committee for the 2010 Winter Olympic games in Whistler, British Columbia could undertake to develop a leadership role in bringing sustainable, long term benefits to the regional transportation system. The Bid Corporation placed emphasis on the use of public and active transportation to move spectators during the two week event. The emphasis was on transportation demand management measures to mitigate traffic impacts on regional residents during the games. The Corporation also committed to use alternative fuel and zero emission technology to reduce air pollution. Currently, there is no long range strategic transportation plan for the Sea to Sky Corridor. The author emphasized that the Organizing Committee should work with other agencies to immediately implement permanent public transit and active transportation improvements with investment in active transport and public transit. Other actions that should be implemented include: investment in alternatives to private automobile travel to offset games-related emissions; committing to sustainable use of the Olympic Lane on the Sea to Sky Highway; endowing a sustainable transportation investment fund; promote research into the long term benefits associated with ferry and rail services; developing affordable housing in Whistler to reduce corridor commuting; and, investment in alternative fuel vehicles and infrastructure to reduce public transit emissions. 12 refs., 1 fig., 2 appendices.

  14. Liner Shipping Fleet Deployment with Sustainable Collaborative Transportation

    Directory of Open Access Journals (Sweden)

    Gang Du

    2016-02-01

    Full Text Available Facing sharp competition in the market for shipping companies, it is necessary to make reasonable and efficient decisions to optimize the container shipping line network so as to improve the shipping efficiency and reduce the transportation cost, as well as to realize the transportation sustainability. Therefore, the liner ship fleet deployment problem with collaborative transportation is proposed in this paper. This problem is formulated as a mixed-integer linear programming model that takes collaborative transportation into consideration. The model includes fixed cost, variable cost, berth cost, transport cost, penalty, compensation cost, and so on. To achieve the sustainable development of collaborative transportation, the shipping companies could make a selection between the internal routes and the external routes to serve each task by comparing the distance between the above routes. A real Asia-Europe-Oceania numerical experiment shows that the proposed sustainable collaborative transportation model can be efficiently solved by C++ calling ILOG CPLEX. Results demonstrate that the optimized shipping line network with sustainable collaborative transportation can improve the service efficiency, as well as the service level of shipping companies.

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

    Directory of Open Access Journals (Sweden)

    Dorina Pojani

    2015-06-01

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

    Sustainable transport is an urging issue on a few accounts: The transport sector was responsible for 23% global CO{sub 2} emission in 2007. It also has a number of other effects like air and noise pollution, land use etc. These effects are especially relevant in cities, where already half of the world's population is living today. With a growing world population and ongoing urbanisation the number and share of city dwellers will rise considerably in the next decades. Thus, sustainability in urban transport becomes increasingly important. This report first provides a short overview of the most important data behind the sustainability problems in urban transport. Then the question is addressed, what sustainable mobility is and where the main obstacles are on the path to more sustainability. The central part of the study deals with the most important policies and instruments enhancing sustainable (urban) mobility. The main feature of each section within that part of the study is the combination of theoretical background information and arguments with case studies from developing and transition countries. Accordingly, the reader gets an idea of the vast range of available instruments in order to promote sustainable mobility. But it is also shown that it is not only necessary but also possible to introduce or enhance sustainable urban transport regardless of the income position of the specific region, country or city. Besides, success factors for different instruments are identified, thereby deriving promising routes for countries or a group of countries according to their state of economic development. (orig.)

  20. Sustainable transport practices in Latin America

    Energy Technology Data Exchange (ETDEWEB)

    Rogat, J.; Hinostroza, M. [UNEP Risoe Centre (Denmark)

    2007-05-15

    The rapid growth of Latin American cities beginning in the 70s has led to, among other things, growing mobility and demand for transportation. The lack of efficient, reliable and safe public transport systems has promoted the switch away from buses and trains towards private cars. Some of the impacts of a steadily increasing car fleet have been increased congestion, number of accidents and environmental deterioration. Recognising the potential implications of such a development, policy makers and officials found it necessary and went ahead to reformulate transport policies with the aim of providing safe, cost-effective and environmental-friendly public transport systems. Bus rapid transit (BRT) became the answer in a number of Latin American cities. The successful experiences of Curitiba in Brazil and Bogota in Colombia have served as the source of inspiration for other cities in Latin America, Asia, Europe and the USA. Thus, the BRT represents a unique example of South-South, South-North technology transfer. This paper presents some of the Latin American experiences and discusses their achievement and drawbacks.

  2. Applying visual attention theory to transportation safety research and design: evaluation of alternative automobile rear lighting systems.

    McIntyre, Scott E; Gugerty, Leo

    2014-06-01

    This field experiment takes a novel approach in applying methodologies and theories of visual search to the subject of conspicuity in automobile rear lighting. Traditional rear lighting research has not used the visual search paradigm in experimental design. It is our claim that the visual search design uniquely uncovers visual attention processes operating when drivers search the visual field that current designs fail to capture. This experiment is a validation and extension of previous simulator research on this same topic and demonstrates that detection of red automobile brake lamps will be improved if tail lamps are another color (in this test, amber) rather than the currently mandated red. Results indicate that when drivers miss brake lamp onset in low ambient light, RT and error are reduced in detecting the presence and absence of red brake lamps with multiple lead vehicles when tail lamps are not red compared to current rear lighting which mandates red tail lamps. This performance improvement is attributed to efficient visual processing that automatically segregates tail (amber) and brake (red) lamp colors into distractors and targets respectively.

    Is transportation getting more sustainable? If not, would we know what to do? This paper defines sustainable transport and describes indicators of sustainable transport, which measure the environment impacts of transport (including green-house gas emissions), the financial health of the system, safety, and access. Indicators are particularly important for developing countries because congestion, safety, air pollution, and the economic health of transport providers are usually poor. Illustrative examples are given from cites in the Partnership for Sustainable Urban Transport in Asia, or PSUTA . Future work will reveal the full quantitative picture of these three cities. As tools, indicators summarize trends and relationships among quantities that describe the most important activities, outputs, and side effects - both positive and negative - of transportation activity. Indicators permit diagnosis, evaluation of costs, benefits, and time frame of cures, prognosis based on the cures implemented, evaluation of progress against a base line, rebalancing of the system if goals are not being achieved, and marketing of results. Indicators also draw stakeholders into an objective discussion of each of these steps. Indicators of governance map their roles in solving problems. Indicators of sustainable passenger transport are being developed and deployed with authorities in Pune (India), Hanoi (Viet Nam), and Xi'an (China). The paper describes how authorities assess needs to determine what indicators are necessary (at what precision), mapping the gap of information required to develop indicators, bridging the gap of information and funding data and analysis, and crossing the bridge to commit to a quantitative approach to policymaking and evaluation. The paper concludes with recommendations on both the most important indicators required for the cities, and the most important policy steps required to improve transportation, focusing on emissions (including green-house gases

    The car, and the range of social and political institutions which sustain its dominance, play an important role in many of the environmental problems faced by contemporary society. But in order to understand the possibilities for moving towards sustainability and 'greening cars', it is first necessary to understand the political forces that have made cars so dominant. This book identifies these forces as a combination of political economy and cultural politics. From the early twentieth century, the car became central to the organization of capitalism and deeply embedded in individual identities, providing people with a source of value and meaning but in a way which was broadly consistent with social imperatives for mobility. Projects for sustainability to reduce the environmental impacts of cars are therefore constrained by these forces but must deal with them in order to shape and achieve their goals. Addresses the increasingly controversial debate on the place of the car in contemporary society and its contribution to environmental problems Questions whether automobility is sustainable and what political, social and economic forces might prevent this Will appeal to scholars and advanced students from a wide range of disciplines including environmental politics, political economy, environmental studies, cultural studies and geography

    2007-01-01

    A hybrid hydrogen-carbon (H2CAR) process for the production of liquid hydrocarbon fuels is proposed wherein biomass is the carbon source and hydrogen is supplied from carbon-free energy. To implement this concept, a process has been designed to co-feed a biomass gasifier with H2 and CO2 recycled from the H2-CO to liquid conversion reactor. Modeling of this biomass to liquids process has identified several major advantages of the H2CAR process. (i) The land area needed to grow the biomass is H2 storage in an open loop system. (iv) Reduction to practice of the H2CAR route has the potential to provide the transportation sector for the foreseeable future, using the existing infrastructure. The rationale of using H2 in the H2CAR process is explained by the significantly higher annualized average solar energy conversion efficiency for hydrogen generation versus that for biomass growth. For coal to liquids, the advantage of H2CAR is that there is no additional CO2 release to the atmosphere due to the replacement of petroleum with coal, thus eliminating the need to sequester CO2.

    2011-09-01

    Transport currently represents approximately 19% of the global energy demand and accounts for about 23% of the global carbon dioxide emissions (IEA 2009). As the demand for mobility is expected to continue to increase in the coming decades, the stabilization of atmospheric carbon dioxide levels will require the evolution of transport, along with power generation, building design and manufacturing. The continued development of these sectors will need to include changes in energy sources, energy delivery, materials, infrastructure and human behavior. Pathways to reducing carbon from the transport sector have unique challenges and opportunities that are inherent to the human choices and behavioral patterns that mold the transportation systems and the associated energy needs. Technology, government investment, and regulatory policies have a significant impact on the formulation of transportation infrastructure; however, the role of human behavior and public acceptance on the efficiency and effectiveness of transport systems should not be underestimated. Although developed, rapidly developing, and underdeveloped nations face different challenges in the establishment of transport infrastructure that can meet transport needs while achieving sustainable carbon dioxide emissions, the constraints that establish the domain of possibilities are closely related for all nations. These constraints include capital investment, fuel supplies, power systems, and human behavior. Throughout the world, there are considerable efforts directed at advancing and optimizing the financing of sustainable infrastructures, the production of low carbon fuels, and the production of advanced power systems, but the foundational work on methods to understand human preferences and behavior within the context of transport and the valuation of reductions in carbon dioxide emissions is greatly lagging behind. These methods and the associated understanding of human behavior and the willingness to pay for

  16. Urban sustainable mobility. Part 1: Rationality in transport planning

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available The impact of the transport sector is in the range of 20%-40% in terms of consumption of fossil fuels and emissions of greenhouse gases and particulate matter. In this context, policies aimed at reducing these effects are very important. Many urban areas are trying to adopt planning strategies aimed to a sustainable use of resources often referred to as sustainable mobility. These policies are very different in terms of costs and expected benefits, and the effects of these policies and their combinations are difficult to anticipate on a purely intuitive basis and sometimes the end effect could be contrary to intuitive expectations (e.g. policies aimed to reduce pollution, ending up in increasing it. In this context, the concept of eco-rational planning assumes a central role. This means identifying the right mixture of interventions to be implemented on the transport system that is: rational for the transport system (e.g. reduction in terms of congestion, traffic accidents, travel time and sustainable for people’s health and for the environmental (e.g. emissions reduction and requires minimal economic resources (e.g. lower monetary cost per unit of CO2 saved. The paper discusses the importance of rational decisions in transport planning.

    This is a short version of a scenario study concerning the possibilities to reach an Environmentally Sustainable Transport system in Sweden in a perspective of 30 years. The aim of the scenario study has been to describe one of several possible paths from today`s transport system to an environmentally adopted one. However, this does not imply that the task is to predict how such a transformation can be accomplished. The aim is rather to illustrate what such transformation require in the form of political decisions. The transformation of the transport system in to an environmentally adopted one, is primarily treated as a political problem, and a political perspective has accordingly been chosen for the study. In this English version of the scenario, the carbon dioxide problem is used to illuminate the many conflicts in goals and other problem that will attend an environmental adoption of the Swedish transport system, and to highlight the analytical points of departure for the scenario study. The analysis shows that it is possible to reach the national environmental goals that characterise, with given definitions, an environmentally sustainable transport system. However, this implies many severe political decisions over a long period of time, which in turn, implies a long term national consensus about the importance to reach the overall goal. Other results the scenario points out, is the risk that a policy focused on one sector leads to `solving` a problem by moving it outside systems limitations, and the limitations on a national environmental policy: Being able to count on assistance from other countries through an environmental adoption of the transport system in the European Union or globally, would drastically facilitate the environmental adoption of the Swedish transport system, through, among other things, a more rapid technological development. This indicates the necessity of promoting issues involving transportation and the environment in international

    2013-01-01

    A mixed transportation network design problem considering sustainable development was studied in this paper. Based on the discretization of continuous link-grade decision variables, a bilevel programming model was proposed to describe the problem, in which sustainability factors, including vehicle exhaust emissions, land-use scale, link load, and financial budget, are considered. The objective of the model is to minimize the total amount of resources exploited under the premise of meeting all the construction goals. A heuristic algorithm, which combined the simulated annealing and path-based gradient projection algorithm, was developed to solve the model. The numerical example shows that the transportation network optimized with the method above not only significantly alleviates the congestion on the link, but also reduces vehicle exhaust emissions within the network by up to 41.56%.

    Full Text Available This paper is concerned with building a sustainable policy framework for transport development in Nigeria. Its objective is to review the country’s transport policy initiatives in order to understand the extent to which it addresses Nigeria’s mobility and transportation problems. From published materials and official government documents and files, the study identifies four national policy initiatives which are reviewed and analysed with regard to their context, contents, and consequences. The study reveals that while the policy initiatives could be said to be adequate and comprehensive in terms of their context and contents, the major challenge is implementation of recommended solutions. The study therefore provides a general checklist to guide policy direction, while advocating for policy-based researches and empirical studies in order to provide the data base for formulation of a sustainable national transport policy for Nigeria.

  11. Future Transportation with Smart Grids and Sustainable Energy

    Directory of Open Access Journals (Sweden)

    Gustav R. Grob

    2009-10-01

    Full Text Available Transportation is facing fundamental change due to the rapid depletion of fossil fuels, environmental and health problems, the growing world population, rising standards of living with more individual mobility and the globalization of trade with its increasing international transport volume. To cope with these serious problems benign, renewable energy systems and much more efficient drives must be multiplied as rapidly as possible to replace the polluting combustion engines with their much too low efficiency and high fuel logistics cost. Consequently the vehicles of the future must be non-polluting and super-efficient, i.e. electric. The energy supply must come via smart grids from clean energy sources not affecting the health, climate and biosphere. It is shown how this transition to the clean, sustainable energy age is possible, feasible and why it is urgent. The important role of international ISO, IEC and ITU standards and the need for better legislation by means of the Global Energy Charter for Sustainable Development are also highlighted.

    The overall aim of the Finnish SIMBe project (www.SIMBe.fi) is to significantly accelerate the introduction of sustainable electric mobility in Finland. SIMBe stands for Smart Infrastructures for Electric Mobility in Built Environments. The fundamental assumption of the project is that electric (e-) mobility is inherently more sustainable than mobility based on fossil fuels. However, as has been widely recognized in the e-mobility field, the currently used batteries are expensive, often more expensive than the rest of the particular electric vehicle (EV) that they propel. There are two opposite schools of thought how to address this problem, which can be summarized as follows: a) Leave the battery in peace, as it is precious. Use it only to propel the EV of which it is an integral part. Use it instead of fuel, and do not use it for any other applications. The EV's sole purpose is that of a transportation device. b) Make as much use of the battery as possible, as it is precious. Involve vehicle to grid (V2G) or vehicle to house charging. Additionally, invent new features, meanings and services for the battery driven EV, which go distinctively beyond transport. The SIMBe project decided to opt for school (b), based on the smart energy production and distribution scenario, in which electric and hybrid vehicles' batteries will deliver energy on demand to the grid. SIMBe aims to prepare key Finnish industrial players and consumers for the transition to this new energy-transportation paradigm. But how can we replace the conservative understanding of the 'transport only' school by a holistic view of what features, meanings and services are actually possible by using a large scale fleet of 'batteries on wheels'? The Nordic Climate Festival (at) Aalto provided the unique opportunity to tap into the knowledge and creativity of students within the Nordic countries. Being properly prepared and facilitated, a workshop may provide some insights and

    Currently there are nearly 750 million ground vehicles in service worldwide. They are responsible for 50% of petroleum (oil) consumption and 60% of all greenhouse gas (GHG) emissions worldwide. The number of vehicles is forecasted to double by 2050. Therefore the environmental issues such as noise, emissions and fuel burn have become important for energy and environmental sustainability. This paper provides an overview of specific energy and environmental issues related to ground transportation. The technologies related to reduction in energy requirements such as reducing the vehicle mass by using the high strength low weight materials and reducing the viscous drag by active flow control and smoothing the operational profile, and reducing the contact friction by special tire materials are discussed along with the portable energy sources for reducing the GHG emissions such as low carbon fuels (biofuels), Lithium-ion batteries with high energy density and stability, and fuel cells. The technological challenges and opportunities for innovations are discussed.

    2016-01-01

    Full Text Available Investment volume is considered as an important factor in regional development under current conditions. Logistical infrastructure which ensures a complex transport, distributive, information and other services exerts a significant influence on regional investment attractiveness. Lack of clear vision on development and execution of development strategy for logistics infrastructure from the side of regional authorities results in unwillingness of large federal and transnational companies to provide investments in infrastructure projects. Network of automotive transport terminals is one of the main elements in logistics infrastructure. The network allows to optimize a flow of material goods from the point of their origin to the point of their consumption with the lowest possible costs and the required level of service. Automobile transport is one of the main objects of transport infrastructure and it is characterized by rather high flexibility in comparison with other types of transport facilities that preconditions its widespread application. Network of automobile fleets (terminals has been formed for redistribution of goods traffic within the concerned regions. The purpose of the present research is to develop a mathematical model for formation of transport infrastructure on the territory of regions. The paper proposes an approach for formation of automobile fleet (terminal network on the territory of a large region with due account of the established network of distribution and sorting-out warehouse facilities. A model has been developed for solving the problem pertaining to minimization of aggregate costs related to maintenance of automobile fleets, delivery of goods to and from distribution and sorting-out warehouse facilities to consumers, ferry of empty trucks and goods handling. The model makes it possible to determine optimal number and location area of automobile fleets (terminals while accounting for their possible locations, capacity

    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.

    Diana Ioncică

    2016-11-01

    Full Text Available The article explores the complex relationships between the natural environment , tourist transport and sustainable tourism development. In order to research the impact of natural resources on tourism activity, on the one hand, and the influences of tourism on the environment, on the other hand, statistical and mathematical methods of analysis and forecast were used, namely, the analysis of the dynamics of significant indicators of the natural environment and of tourist activity, the correlation method, the Markov chains method. The analyses made lead us to the conclusion of the existence of a positive evolution of significant indicators of the natural environment, with an impact on tourist activity, such as natural parks. It has been emphasized; also, that this positive evolution has a direct influence on the attraction of visitors, specifically, foreign ones, but the intensity of this influence is average. The intensification of the actions of promotion of natural parks and, generally, of protected areas in Romania, would be a direction for attracting an increased number of visitors, with all the favourable economic consequences. On the other hand, the research has outlined the fact that, as far as the means of transportation used by tourists to visit Romania are concerned, on the first places we can see road and air transport, means of transportation which, aside from the obvious advantages for tourists, have a strong negative impact on the environment. The forecast made with the help of the Markov chains method has shown a negative trend, from the point of view of the impact on the environment, namely an increase in the share of road and air transport in the preference of foreign visitors to Romania. The current research represents a contribution to the efforts of measuring, through statistical and mathematical models, of the complex influences, in both senses, between the environment and tourist activity. Thus, an objective radiography has

    Strickland, G.

    1979-01-01

    Results of an analysis of hydrogen-fueled automobiles are presented as a part of a continuing study conducted by Lawrence Livermore Laboratory (LLL) on Energy Storage Systems for Automobile Propulsion. The hydrogen is stored either as a metal hydride at moderate pressure in TiFe/sub 0/ /sub 9/Mn/sub 0/ /sub 1/H/sub x/ and at low pressure in MgH/sub x/ catalyzed with 10 wt % Ni, or it is stored in hollow glass microspheres at pressures up to about 400 atm. Improved projections are given for the two hydrides, which are used in combination to take advantage of their complementary properties. In the dual-hydride case and in the microsphere case where Ti-based hydride is used for initial operation, hydrogen is consumed in an internal-combustion engine; whereas in the third case, hydrogen from Ti-based hydride is used with air in an alkaline fuel cell/Ni-Zn battery combination which powers an electric vehicle. Each system is briefly described; and the results of the vehicle analysis are compared with those for the conventional automobile and with electric vehicles powered by Pb-acid or Ni-Zn batteries. Comparisons are made on the basis of automobile weight, initial user cost, and life-cycle cost. In this report, the results are limited to those for the 5-passenger vehicle in the period 1985-1990, and are provided as probable and optimistic values.

  19. Life cycle models of conventional and alternative-fueled automobiles

    Science.gov (United States)

    Maclean, Heather Louise

    This thesis reports life cycle inventories of internal combustion engine automobiles with feasible near term fuel/engine combinations. These combinations include unleaded gasoline, California Phase 2 Reformulated Gasoline, alcohol and gasoline blends (85 percent methanol or ethanol combined with 15 percent gasoline), and compressed natural gas in spark ignition direct and indirect injection engines. Additionally, I consider neat methanol and neat ethanol in spark ignition direct injection engines and diesel fuel in compression ignition direct and indirect injection engines. I investigate the potential of the above options to have a lower environmental impact than conventional gasoline-fueled automobiles, while still retaining comparable pricing and consumer benefits. More broadly, the objective is to assess whether the use of any of the alternative systems will help to lead to the goal of a more sustainable personal transportation system. The principal tool is the Economic Input-Output Life Cycle Analysis model which includes inventories of economic data, environmental discharges, and resource use. I develop a life cycle assessment framework to assemble the array of data generated by the model into three aggregate assessment parameters; economics, externalities, and vehicle attributes. The first step is to develop a set of 'comparable cars' with the alternative fuel/engine combinations, based on characteristics of a conventional 1998 gasoline-fueled Ford Taurus sedan, the baseline vehicle for the analyses. I calculate the assessment parameters assuming that these comparable cars can attain the potential thermal efficiencies estimated by experts for each fuel/engine combination. To a first approximation, there are no significant differences in the assessment parameters for the vehicle manufacture, service, fixed costs, and the end-of-life for any of the options. However, there are differences in the vehicle operation life cycle components and the state of technology

    Full Text Available This paper addresses a coordination problem of production and green transportation and the effects of production and transportation coordination on supply chain sustainability in a global supply chain environment with the consideration of important realistic characteristics, including parallel machines, different order processing complexities, fixed delivery departure times, green transportation and multiple transportation modes. We formulate the measurements for carbon emissions of different transportation modes, including air, sea and land transportation. A hybrid genetic algorithm-based optimization approach is developed to handle this problem, in which a hybrid genetic algorithm and heuristic procedures are combined. The effectiveness of the proposed approach is validated by means of various problem instances. We observe that the coordination of production and green transportation has a large effect on the overall supply chain sustainability, which can reduce the total supply chain cost by 9.60% to 21.90%.

    2010-07-01

    This paper undertakes a macro-level analysis of the present transportation sector in Romania while exploring potential strategic options within the context of integrating the existing European environmental policies that address the sustainability factor. The intention is to develop a framework that will help the Romanian sector of transport to identify the targets and strategies for the development and deployment of such policies in order to minimize the effects of the existing pollutant modes of transportation. The fast adoption of such pertinent strategies for the development and implementation of a public transportation, rail, naval and multimodal transportation seems to be the key factor in the introduction of a sustainable transport system in Romania. Despite some very serious obstacles that are presently challenging the Romanian transport system, the development of a transportation infrastructure that is built upon the principles of sustainable development will ask for a reorientation in favor of new transportation modes that are less pollutant and much more energy efficient. It is assumed that in order to allow for such retrenchment to occur some key changes in the Romanian transport policy priorities will need to take place.

    Full Text Available Due to the rapid deregulation of freight transport in South Africa two decades ago, and low historical investment in rail (with resultant poor service delivery, an integrated alternative to road and rail competition was never developed. High national freight logistics costs, significant road infrastructure challenges and environmental impact concerns of a road-dominated freight transport market have, however, fuelled renewed interest in intermodal transport solutions. In this article, a high-level business case for domestic intermodal solutions in South Africa is presented. The results demonstrate that building three intermodal terminals to connect the three major industrial hubs (i.e. Gauteng, Durban and Cape Town through an intermodal solution could reduce transport costs (including externalities for the identified 11.5 million tons of intermodalfriendly freight flows on the Cape and Natal corridors by 42% (including externalities.

    In the twenty-first century the sustainability of energy and transportation systems is on the top of the political agenda in many countries around the world and governments are establishing policies towards a sustainable, low emissions energy future. Environmental impacts of human economic activity necessitate the consideration of conflicting goals in decision making processes to develop sustainable systems. Any sustainable development has to reconcile conflicting economic and environmental objectives and criteria. The science of multiple criteria decision making has a lot to offer in addressing this need. Decision making with multiple (conflicting) criteria is the topic of research that is at the heart of the International Society of Multiple Criteria Decision Making. This book is based on selected papers presented at the societies 19th International Conference, held at The University of Auckland, New Zealand, from 7th to 12th January 2008 under the theme ''MCDM for Sustainable Energy and Transportation Systems''.

    1996-11-01

    This talk discusses the technical options available for automobiles within the next 5 to 10 years. With the objective to reduce consumption and pollution, several alternative approaches are presented and analyzed using simplified but realistic calculations. Main emphasis is laid on CO{sub 2} emission of the complete energy transformation path from the primary energy carrier to the energy dissipated in test cycles. It is shown that no single optimal solution exist but that a trade-off between consumption, pollution and cost must be made for each specific situation. (author) 17 figs., 2 tabs.

  1. Code Recognition Device for Automobile, a Panacea for Automobiles Theft

    Full Text Available Code Recognition Device is a security device for automobiles. It responds only to the right sequence of codes that are keyed from the key pad. This closes the electrical circuitry of the automobile and enables it to start. If a wrong key is touched, it resets the device which disengages the electrical circuit of the automobile from the power supply. The device works properly on closing all the doors of the automobile, otherwise it cannot start. Also, once the automobile is in operation, opening of any door will disengage the device and the engine will stop. To restart the engine, the doors must be closed and the codes rendered sequentially-in this case the codes are 1974.

    2009-05-01

    Full Text Available Monetary instruments to regulate parking are often used in central areas of cities to discourage long term parking of vehicles. The availability of parking facilities, and its cost, in fact represents an important element in the decision to operate private vehicles in urban areas. The availability of instruments and tools to check the outcome of modification in parking regulations, in terms of modification of car use, successfully support planners in the determination of the best policies to decrease congestion, and regulate the use of transportation in cities. Integrated land use transportation models may successfully contribute to the assessment of such policy packages. This contribution discusses the use of the model MARS-Bari (Metropolitan Activity Relocation Simulator for the analysis of future scenarios of development of land use and transportation. MARS-Bari is a fast integrated land use transportation model, which is designed for applications in strategic planning of urban and metropolitan areas. The model was developed as a decision support tool, to help planners in the definition of sets of policies on land use and transportation, and promote equilibrated growth of the urban system (smart growth. MARS-Bari shares the basic assumptions of the Metropolitan Activity Relocation Simulator (MARS modeling system, so far successfully applied to many cities of both Europe and Asia. The structure of MARS-Bari is highly flexible on purpose, allowing multiple hypothesis tests of future scenarios and policies. MARS-Bari works at a high level of spatial aggregation, and its simulations are developed on a long-term time horizon (30-years in the current version. Two main sub-models run in MARS-Bari: they respectively simulate the development of land use, and the transportation system. Four different classes of users are distinguished in the transportation model, depending on the possible access to one or more of the five transportation modes: car

  5. Proustian Metaphor and the Automobile

    Directory of Open Access Journals (Sweden)

    Shawn Gorman

    2005-06-01

    Full Text Available In Marcel Proust's Sodome et Gomorrhe , the automobile produces a transformation in the relationship between space and time and, by analogy, a parallel transformation in art. In Proust's famous notion of involuntary memory, the similarity of a past sense impression to a present one leads to transcendence of time and space, and ultimately to metaphor. The metonymical speed of the automobile endlessly chases the sort of metaphorical "simultaneity" at work in involuntary memory. Structurally, the automobile offers the possibility of bringing together two terms by eliminating the middle term (time, space that separated them; yet the automobile is never fast enough to reach the atemporal perfection of metaphor, and the third term reappears. We therefore examine how the automobile in this and other texts by Proust exhibits both metaphorical and metonymical properties. The automobile creates unexpected connections and reveals, in a displaced form, surprising relationships among characters, emotions, objects, and symbols. In its role as metaphor, the automobile stands for processes that are negatively marked, like aesthetic fetishism, while in its role as metonymy, the automobile leads to pleasure and appeasement.

  6. Developing a Collaborative Planning Framework for Sustainable Transportation

    2014-01-01

    Full Text Available Currently, as being the highest petroleum consuming sector in the world, transportation significantly contributes to the total greenhouse gas emissions in the world. Road transportation not only is responsible for approximately 20% of the total emissions of carbon dioxide in the EU and in the US but also has a steadily increasing trend in contributing to global warming. Initiatives undertaken by authorities, such as Emission cap and trade in the EU, limit the emissions resulted from the actions of the companies and also give economic incentives to companies to reduce their emissions. However, in logistics systems with multiple entities, it is difficult to assess the responsibilities of the companies both in terms of costs and emissions. In this study, we consider a delivery network with multiple customers served by a single carrier, which executes a delivery plan with the minimum transportation cost, and allocate the resulting costs and the emissions among the customers in a fair manner. We develop allocation mechanisms for both costs and emissions. In order to develop a mechanism that provides further reduction of the emissions, we study a setting where the carrier takes the responsibility of the emissions and reflects the resulting inefficiencies while charging the customers.

    2017-01-01

    Full Text Available This paper deals with actual European “modal shift to rail transport” concept and related environmental issues and experience in the Republic of Serbia. The planned increase in volume of railway transport and planned railway electrification should reduce air pollution in Serbia, particularly in the urban environment. On the other hand, achieving this goal would lead to the increase in noise level in the urban environment and environmental issues in the region of thermal power plants, which are the main sources of electricity in Serbia. This paper suggests concrete measures to reduce the railway carbon footprint and noise level during the planning, design and service life of railway infrastructure.

  11. Quantifying a Financially Sustainable Strategy of Public Transport: Private Capital Investment Considering Passenger Value

    Yunqiang Xue

    2017-02-01

    Full Text Available Releaving traffic congestion by developing public transport as an alternative mode of travel is a common practice all over the world. However, the increasing public transport subsidies have created a financial burden for governments. Encouragingly, private capital supplies an opportunity for public transport in sustainable finance. Previous research mainly focuses on qualitative analysis and money-for-value (MFV analysis. In this paper, a new investment model is proposed based on the concept ‘passenger value’, and a bi-level programming model (BLPM is constructed as a quantitative analysis tool. The upper target of BLPM is the total surplus (including the value of time (VOT of passengers of the public transport system and the upper constraint is the ticket price. The lower target of BLPM is passenger’s surplus, the lower constraints are service capability and the lowest return rate of the private sector. The public transport of Jinan City, China is taken as a case to quantify the impacts of private capital investment in public transport. Results show that the proposed investment model considering passenger value is superior to the traditional one, and effective private capital investment could increase the total societal benefit of the transportation system. The proposed investment strategy satisfies economic viability and is a financially sustainability strategy. Additionally, travelers should be encouraged to use public transport through improving the service quality and passenger returns. Only in this way can the success rate of the private sector investment in public transport be improved efficiently.

    The reduction of the number of retail shops, in principle, provide for better planning opportunities regarding the distribution of commodities to the shops. But this, according to the study is more than offset by the longer distances the goods have to travel before reaching the shops. The report investigates the potentials for reduction of the energy demand and emission by means of technical improvements of vehicles. The assessments are based on fuel cycle considerations covering both the energy system (that is, the system providing the fuel to the vehicle) and the vehicle system (the system on board the vehicle transforming the fuel to useful work). In general, there are substantial potentials for improvements of the energy efficiency of the transportation means - and even greater potentials for CO{sub 2}-reductions. The reap the full potentials, it is probably necessary to break with the present technological development trend. (au) 274 refs.

    2009-11-01

    This paper offers the description of an integrated information system framework for the assessment of transportation planning and management. After an introductory exposition, in the first part of the paper, a broad overview of international experiences regarding information systems on transportation is given, focusing in particular on the relationship between transportation system's performance monitoring and the decision-making process, and on the importance of this connection in the evaluation and planning process, in Italian and European cases. Next, the methodological design of an information system to support efficient and sustainable transportation planning and management aiming to integrate inputs from several different data sources is presented. The resulting framework deploys modular and integrated databases which include data stemming from different national or regional data banks and which integrate information belonging to different transportation fields. For this reason, it allows public administrations to account for many strategic elements that influence their decisions regarding transportation, both from a systemic and infrastructural point of view.

    Comfort on automobile seats is lived daily by thousands of drivers. Epistemologically, comfort can be understood under the theory of complexity, since it emerges from a chain of interrelationships between man and several elements of the system. This interaction process can engender extreme comfort associated to the feeling of pleasure and wellbeing or, on the other hand, lead to discomfort, normally followed by pain. This article has for purpose the development of a theoretical model that favours the comfort feature on automobile seats through the identification of its facets and indicators. For such, a theoretical study is resorted to, allowing the mapping of elements that constitute the model. The results present a comfort model on automobile seats that contemplates the (physical, psychological, object, context and environment) facets. This model is expected to contribute with the automobile industry for the development of improvements of the ergonomic project of seats to increase the comfort noticed by the users.

  20. Sustainable intermodal freight transportation: Applying the geospatial intermodal freight transport model

    Science.gov (United States)

    Comer, Bryan

    To study the energy and environmental impacts of emissions associated with freight transportation, the Geospatial Intermodal Freight Transport (GIFT) model was created as a joint research collaborative between the Rochester Institute of Technology (RIT) and the University of Delaware (UD). The GIFT model is a Geographic Information Systems (GIS) based model that links the U.S. and Canadian water, rail, and road transportation networks through intermodal transfer facilities to create an intermodal network. The purpose of my thesis is to apply the GIFT model to examine potential public policies related to intermodal freight transportation in the Great Lakes region of the United States. My thesis will consist of two papers. The first paper will examine the environmental, economic, and time-of-delivery tradeoffs associated with freight transportation in the Great Lakes region and examine opportunities for marine vessels to replace a portion of heavy-duty trucks for containerized freight transport. The second paper will explore the potential benefits of using the Great Lakes as a corridor for short-sea shipping as part of a longer intermodal route. The intent of my thesis is to shed light on the current issues associated with freight transport in the Great Lakes region and present public policy alternatives to address said issues. Ideally, this thesis will better inform policymakers on the impacts and tradeoffs associated with freight transportation.

    Transportation industry is rapidly developing owing to its size and importance which affects on various aspects of life. It includes all the transport means that facilitate mobility of people or goods either by air, land or sea like aircrafts, automotives, ships, trains, etc. The utilization of textiles in this industry is increasing as a result of moving towards achieving sustainability and enhancing performance, comfort and safety. Through substituting heavier materials with textiles of high performance specifications and textile reinforced composites to reduce weight, fuel consumption and CO2 emissions. Composite materials can fulfil the demands for sustainability in the transportation sector through using renewable, recycled and lightweight materials, considering the requirements of each category of transport vehicles. Textiles used in reinforcing composites are diverse including fibers, yarns or fabric preforms such as woven, nonwoven, knitted, braided which varies from 2D to complex 3D structures. This paper presents a brief review on the utilization of textiles in reinforcing composites for various transportation applications to achieve sustainability. Also, discussing the influence of textiles structural parameters like fiber material properties, fabric production technique and construction on their mechanical behaviour.

    Nahdalina; Hadiwardoyo, S. P.; Nahry

    2017-05-01

    Sustainable transport is closely related to quality of life in the community at present and in the future. Some indicators of transport sustainability are accessibility measurement of origin/destination, the operating costs of transport (vehicle operating cost or VOC) and external transportation costs (emission cost). The indicators could be combined into accessibility measurement model. In other case, almost traffic congestion occurred on the condition of mixed traffic. This paper aimed to analyse the indicator of transport sustainability through simulation under condition of various traffic composition. Various composition of truck to total traffic flow are 0%, 10% and 20%. Speed and V/C are calculated from traffic flow to estimate the VOC and emission cost. 5 VOC components and 3 types of emission cost (CO2, CH4 and N2O) are counted to be a travel cost. Accessibility measurement was calculated using travel cost and gravity model approaches. Result of the research shows that the total traffic flow has indirect impact on accessibility measurement if using travel cost approach. Meanwhile, the composition of traffic flow has an affect on accessibility measurement if using gravity model approach.

    2013-06-28

    This collaborative educational project between the University of Michigan—Ann Arbor, University of Michigan—Dearborn and the Kettering University successfully executed almost all the elements we proposed to do. In the original proposal, we proposed to develop four graduate courses, six undergraduate courses, four professional short courses, a K-12 electric vehicle education kit, a Saturday morning seminar series, and a set of consumer education material to support the advancement of transportation electrification. The first four deliverables were all successfully developed and offered. When we held the kick-off meeting in NETL in Morgantown back in early 2010 with all the ten ARRA education teams, however, it quickly became clear that among the ten ARRA education grantee teams, our proposed “consume education” activities are not better or with the potential to create bigger impact than some of activities proposed in other teams. For example, the Odyssey 2010 event held by the West Virginia University team had planned and successfully reached to more than 230,000 attendees, which is way more than what our proposed 100k event could ever reach. It was under the suggestion of Joseph Quaranta, the ARRA education Program Director at that time, that we should coordinate and eliminate redundancy. The resources should then be focused on activities that have less overlap. Therefore, the originally proposed activities: Saturday morning seminar series, and a set of consumer education material were dropped from our scope. We expanded the scope of our “education kit” activity to include some educational materials, mainly in the form of videos. The target audience also changed from general public to K-12 students. The majority of the project cost (~70%) goes toward the establishment of three undergraduate laboratories, which provides critically needed hands-on learning experience for next-generation green mobility engineers. We are very proud that the ARRA money

    2017-02-01

    Full Text Available In response to the present dynamic market, automobile manufacturing industries are constantly evaluating and improving their manufacturing strategies to stay competitive. It is also evident that they evaluate those strategies considering multiple criteria. In one such case, an automobile project manager has to ensure that the selected tire (among the available alternatives complies with the prospective automobile’s performance. This paper presents an approach for the assessment of alternative automobile tires taking into account multiple criteria, such as tire sustainability, tire road performance, environmental issues, tire purchase cost and tire road grip. The presented approach is quite helpful to any decision maker who is interested not only in ranking alternatives but also in establishing the superiority of an alternative over others. The approach also helps to specify the position of each alternative with respect to ideal solution. A case illustration is used to demonstrate an application of the approach.

    Full Text Available In many EU cities, trolleybuses are experiencing a period of revitalization. New lines, state-of-the-art designs, the use of auxiliary propulsion batteries, ecological values and other factors offer great opportunities for this kind of public transport as an effective tool to shape transport policy in accordance with the principles of sustainable mobility. Gdynia is one of three cities in Poland with a trolleybus public transport subsystem. Since the beginning of political and economic transformation, Gdynia’s authority consistently implements measures aimed at balancing urban mobility, above all by improving the quality of public transport services and creating conditions for the development of alternatives forms of transport to private car travel. The experience of the development of trolleybuses in Gdynia as an element of sustainable mobility, the nature of this means of transport in both economic and operation terms, the implementation of original technological solutions in the trolleybuses’ construction and the impact on decision-making by marketing research are the areas of interest in this paper.

    2013-01-01

    Full Text Available In the context of sustainable transportation systems, previous studies have either focused only on the transportation system or have not used a methodology that enables the treatment of incomplete, vague, and qualitative information associated with the available data. This study proposes a system of systems (SOS and a fuzzy logic modeling approach. The SOS includes the Transportation, Activity, and Environment systems. The fuzzy logic modeling approach enables the treatment of the vagueness associated with some of the relevant data. Performance Indices (PIs are computed for each system using a number of performance measures. The PIs illustrate the aggregated performance of each system as well as the interactions among them. The proposed methodology also enables the estimation of a Composite Sustainability Index to summarize the aggregated performance of the overall SOS. Existing data was used to analyze sustainability in the entire United States. The results showed that the Transportation and Activity systems follow a positive trend, with similar periods of growth and contractions; in contrast, the environmental system follows a reverse pattern. The results are intuitive and are associated with a series of historic events, such as depressions in the economy as well as policy changes and regulations.

    Full Text Available Today’s automobiles leverage powerful sensors and embedded computers to optimize efficiency, safety, and driver engagement. However the complexity of possible inferences using in-car sensor data is not well understood. While we do not know of attempts by automotive manufacturers or makers of after-market components (like insurance dongles to violate privacy, a key question we ask is: could they (or their collection and later accidental leaks of data violate a driver’s privacy? In the present study, we experimentally investigate the potential to identify individuals using sensor data snippets of their natural driving behavior. More specifically we record the in-vehicle sensor data on the controllerarea- network (CAN of a typical modern vehicle (popular 2009 sedan as each of 15 participants (a performed a series of maneuvers in an isolated parking lot, and (b drove the vehicle in traffic along a defined ~ 50 mile loop through the Seattle metropolitan area. We then split the data into training and testing sets, train an ensemble of classifiers, and evaluate identification accuracy of test data queries by looking at the highest voted candidate when considering all possible one-vs-one comparisons. Our results indicate that, at least among small sets, drivers are indeed distinguishable using only incar sensors. In particular, we find that it is possible to differentiate our 15 drivers with 100% accuracy when training with all of the available sensors using 90% of driving data from each person. Furthermore, it is possible to reach high identification rates using less than 8 minutes of training data. When more training data is available it is possible to reach very high identification using only a single sensor (e.g., the brake pedal. As an extension, we also demonstrate the feasibility of performing driver identification across multiple days of data collection

    2017-10-01

    Patterns of urban land use are inherently linked to the predominantly used means of transportation, both generating and being generated themselves. While each mode of transportation shapes a different development typology a clear understanding of their interrelations and dependencies is needed in order to create a comprehensive mobility strategy. The study proposes a 15-criteria analysis framework developed to identify and quantify the main modes of transportation’s key aspects. The analysis framework was applied to a yearlong research on Timisoara, Romania, comprising hard, quantitative data, digital simulations and mobility pattern analysis and soft data, quality assessment and perceived needs and satisfaction levels. The research was carried out in clear opposition to the national trend of official mobility strategies focusing on accommodating increased levels of car traffic on the underdeveloped existing roads infrastructure. By analysing the efficiency and sustainability of all four main modes of transportation the results offer a holistic comprehensive view. While, despite current practices, no mobility strategy can focus on a single means of transportation, the article will only present in detail the research on cycling, infrastructure and use, as it is the most underdeveloped and least discussed at the national level and proven through our study to be the most efficient for a city of Timisoara’s size and characteristics. By identifying a clear link between urban land use patterns, infrastructure quality and perceptions and the most efficient means of transportation for each particular city type mobility strategies could shift the trend of urban development towards a more sustainable one.

  19. Reducing automobile traffic: an urgent policy for health promotion

    Directory of Open Access Journals (Sweden)

    Tapia Granados José A.

    1998-01-01

    Full Text Available In recent decades traffic injuries have become a leading cause of death and disability the world over. In congested urban areas, the noise and emissions from vehicle engines cause discomfort and disease. More than one billion people are exposed daily to harmful levels of atmospheric contamination. Because internal combustion generates carbon dioxide (CO2 , the automobile is a principal contributor to the greenhouse effect, which has significantly raised the temperature of the atmosphere. Scientists anticipate that in coming decades the greenhouse effect will produce alterations in climate that are very likely to be harmful and possibly catastrophic. Meanwhile, burgeoning traffic and rural and urban highway infrastructures are already among the principal causes of environmental degradation. Urban development, because it is nearly always "planned" to accommodate automobiles rather than people, reduces the quality of life and tears the social fabric. In contrast to private automobiles, public transportation, bicycles, and walking produce little environmental contamination or injury-related morbidity and mortality. These modes of transport involve more physical activity, with its positive health effects, and avoid contributing to the greenhouse effect. The reduction of automobile traffic and substitution of alternative modes of transport are essential policies for health promotion. They should be incorporated in "healthy cities" programs and general economic policies.

    2017-09-01

    Efficient techniques for both nonlinear numerical analysis of concrete structures and advanced stochastic simulation methods have been combined in order to offer an advanced tool for assessment of realistic behaviour, failure and safety assessment of transport structures. The utilized approach is based on randomization of the non-linear finite element analysis of the structural models. Degradation aspects such as carbonation of concrete can be accounted in order predict durability of the investigated structure and its sustainability. Results can serve as a rational basis for the performance and sustainability assessment based on advanced nonlinear computer analysis of the structures of transport infrastructure such as bridges or tunnels. In the stochastic simulation the input material parameters obtained from material tests including their randomness and uncertainty are represented as random variables or fields. Appropriate identification of material parameters is crucial for the virtual failure modelling of structures and structural elements. Inverse analysis using artificial neural networks and virtual stochastic simulations approach is applied to determine the fracture mechanical parameters of the structural material and its numerical model. Structural response, reliability and sustainability have been investigated on different types of transport structures made from various materials using the above mentioned methodology and tools.

    The objective of this study was to evaluate the proportion and characteristics of patients sustaining major trauma in road traffic crashes (RTCs) who could benefit from direct transportation to a trauma center (TC). Currently, there is no national classification of TC in Sweden. In this study, 7 university hospitals (UHs) in Sweden were selected to represent a TC level I or level II. These UHs have similar capabilities as the definition for level I and level II TC in the United States. Major trauma was defined as Injury Severity Score (ISS) > 15. A total of 117,730 patients who were transported by road or air ambulance were selected from the Swedish TRaffic Accident Data Acquisition (STRADA) database between 2007 to 2014. An analysis of the patient characteristics sustaining major trauma in comparison with patients sustaining minor trauma (ISS car, truck, or bus and to be involved in a crash in a rural location. Our results show that the majority of RTC major trauma patients are transported to a non-TC. This may cause unnecessary morbidity and mortality. These findings can guide the development of improved prehospital treatment guidelines, protocols and decision support systems.

  2. Resource Allocation for Sustainable Urban Transit from a Transport Diversity Perspective

    Directory of Open Access Journals (Sweden)

    Cheng-Min Feng

    2009-11-01

    Full Text Available Different transport stakeholders have different needs for transport infrastructure and services. Meeting the needs of all stakeholders implies a trade-off of benefits and costs between supply and demand and creates transport diversity issues. However, the literature has largely ignored these issues. Transport diversity can assess the level to which important needs are satisfied equitably, and monitor whether transportation systems are moving towards sustainability by confirming the targets and basic level of quality of life. Based on the concept of transport diversity, this study utilizes fuzzy multi-objective programming to solve non-linear multi-objective problems involving urban public transit systems to determine the impact of resource allocation on needs satisfaction in relation to stakeholder behaviors. The proposed approach avoids problems of inefficient and inequitable resource allocation. A real-life case is presented to demonstrate the feasibility of applying the proposed methodology. Furthermore, empirical outcomes show that recent investments allocated to public transit systems considered equitable stakeholder satisfaction for both mass rapid transit (MRT and bus, and also promoted transport diversity in the Taipei metropolitan area.

    Full Text Available The Danube is the second longest European river that flows through ten countries and covers an area inhabited by 115 million people. It can be observed in geographical, transport, economic, historical and ecological terms. This paper analyses the environmental aspects with special reference to transport on inland waterways as well as pollution that can be result of such transport. The Danube is a specific river that, besides its size, is marked by the diversity in the morphology and hydrology. It is characterized by stunning landscape and unique biodiversity, rare natural habitats and it stands out as an ecologically important area of Europe. Since the subject of protection and improvement of the water status of the Danube is very extensive and requires analysis through multiple branches of law, after the definition of key concepts necessary for a better understanding of the paper, it analyses regulations of inland navigation, environmental provisions, and significant ecological norms of other areas of law, at national and international level. After analysing a number of norms related to the title of the article the author proposes concrete measures to improve the situation.

    The automobile and associated mobility system have had a major economic and ecological impact on human societies. The industrial revolution, during which the internal combustion engine has played a major role, has shaped secular, materialistic societies and associated consumption patterns that cannot be sustained in a future world of eight billion people. Creating a more sustainable world means maximizing human satisfaction while minimizing human impact on nature. Becoming more sustainable is best envisioned as a continuing process in which constraints and possibilities change over time and space. The sustainable process raises major controversies including how to define and measure progress, how to apportion wealth among generations, and between free trade and environmental preservation. Sustainable mobility implies major changes in approaches to transportation including stressing psychological rather than physical mobility, designing speciality vehicles for emerging niches, and placing special emphasis on mass transit systems for emerging megacities.

    T.R. Lakshmanan, director of the Bureau of Transportation Statistics, offered the following definition from the Bruntland Commission: ``Sustainable development is development that meets the needs of the present generations without compromising the ability of future generations.`` The technologies and policies that received the most attention would provide per-unit-of-service reduction of three kinds of social costs (external costs, in economist`s terminology) with respect to light duty transportation. The main factors to be reduced were oil use, greenhouse gases, and air pollution. Undesirable side effects of continually expanding transportation activity, including congestion and habitat loss, were also discussed. The conference included debate about priorities among these five categories of social cost, about which organizations should take action to achieve the reductions needed in each, and about what specific actions these organizations should take.

    2014-12-01

    While energy efficient transportation strategies have the potential to simultaneously slash oil consumption and reduce greenhouse gas (GHG) emissions, a truly sustainable solution will require more than just putting drivers behind the wheels of new fuel-efficient cars. As the only national laboratory dedicated 100% to renewable energy and energy efficiency, the National Renewable Energy Laboratory (NREL) accelerates widespread adoption of high-performance, low-emission, energy-efficient passenger and freight vehicles, as well as alternative fuels and related infrastructure. Researchers collaborate closely with industry, government, and research partners, using a whole-systems approach to design better batteries, drivetrains, and engines, as well as thermal management, energy storage, power electronic, climate control, alternative fuel, combustion, and emission systems. NREL's sustainable transportation research, development, and deployment (RD&D) efforts are not limited to vehicles, roads, and fueling stations. The lab also explores ways to save energy and reduce GHGs by integrating transportation technology advancements with renewable energy generation, power grids and building systems, urban planning and policy, and fleet operations.

This situation causes congestion to happen in this area especially during weekend and holiday and lead to air pollution. Hence, it is important to solve this problem beginning with the transport system and brings the city toward the sustainable way by learning the foreign city experience. In this research, the researchers start to revise the case study from foreign city councils on what and how they improve their cities transport system in term of sustainability. There are total of 17 case studies been studied including the cities that recognize with Sustainable Transport Award (STA) and other special activity and event that held worldwide. These cases studied are merged with the behavioral modification. There are four methods of changing behavior: positive reinforcement, negative reinforcement, punishment and extinction. Besides, the data from the administrative staff (HTJMC's officer) also important to success the planning. There are 16 officers that involved in this research and the data that obtained is used as the primary data resources. By knowing the behavioral modification and suggestion that brought by each case studies, the researchers will conclude whether the solution practicable in Ayer Keroh, Melaka or not. Throughout the research, the researchers can conclude that the not all the foreign experience is practical in Ayer, Keroh, Melaka due to the problem of weather, culture and technology that available in the city. The experience from foreign city cannot be exactly to implement in the city but need to redesign to match culture in the city.

    The widespread of transport is recognized as a major contributor to an extensive range of undesirable side effects, covering all stages, from production to use and disposal. The transport sector is one of the major consumers of energy mainly fossil fuels and therefore contributes adverse emissions with local direct health effects as well as a significant share of 'greenhouse gases' (GHGs), which play a crucial role in determining the earth's climate. Moreover, the transportation sector is implicated in causing some social problems such as intensive use of public space. Present growth in vehicle ownership and use in urban areas, is unsustainable. Petroleum fuels, which are the main energy source for the transport sector, are essentially non-renewable. In short, the transportation system is unsustainable and is becoming more unsustainable. Measures need to be taken at a number of levels to mitigate the negative effects of transport and to reduce the increasing dependence on the fossil fuels as a main transportation energy soruce. The main objectives of this study are: (a) analyzing the transportation's role in the energy markets and its related environmental problems and defining the sustainable transport in urban areas, (b) analyzing alternative urban planning philosophies, (c) presenting a suggested procedure for sustainable develop ment of urban transport and energy consumption, (d) identifying the potential impacts of this procedure by being applied to Alexandria city, as a case study. The identification is based on evaluating four different scenarios for the year 2015 which are compared to each other, as well as with a business-as usual scenario (Do-Nothing Solution). These scenarios are based on the proposed sustainable transport and energy systems started from (Do-Minimum Solution) until (Do-Maximum Solution).

    International commerce places unique pressures on the sustainability of water resources and marine environments. System impacts include noise, emissions, and chemical and biological pollutants like introduction of invasive species into key ecosystems. At the same time, maritime trade also enables the sustainability ambition of intragenerational equity in the economy through the global circulation of commodities and manufactured goods, including agricultural, energy and mining resources (UN Trade and Development Board 2013). This paper presents a framework to guide the analysis of the multiple dimensions of the sustainable commerce-ocean nexus. As a demonstration case, we explore the social, economic and environmental aspects of the nexus framework using scenarios for the production and transportation of conventional and bio-based energy commodities. Using coupled LCA and GIS methodologies, we are able to orient the findings spatially for additional insight. Previous work on the sustainable use of marine resources has focused on distinct aspects of the maritime environment. The framework presented here, integrates the anthropogenic use, governance and impacts on the marine and coastal environments with the natural components of the system. A similar framework has been highly effective in progressing the study of land-change science (Turner et al 2007), however modification is required for the unique context of the marine environment. This framework will enable better research integration and planning for sustainability objectives including mitigation and adaptation to climate change, sea level rise, reduced dependence on fossil fuels, protection of critical marine habitat and species, and better management of the ocean as an emerging resource base for the production and transport of commodities and energy across the globe. The framework can also be adapted for vulnerability analysis, resilience studies and to evaluate the trends in production, consumption and

    With mandates and regulatory policies to meet both the California Air Resources Board (CARB) and the Partnership for a New Generation of Vehicles (PNGV), designing vehicles of the future will become a difficult task. As we look into the use of electric and hybrid vehicles, reduction of the required power demand by influential automobile components is necessary in order to obtain performance and range goals. Among those automobile components are accessories. Accessories have a profound impact on the range and mileage of future vehicles with limited amounts of energy or without power generating capabilities such as conventional vehicles. Careful assessment of major power consuming accessories helps us focus on those that need improvement and contributes to attainment of mileage and range goals for electric and hybrid vehicles.

    Full Text Available Both the domestic and international academic literature’s analysis of links between transport and wellbeing focuses mainly on urban settings and vulnerable population groups including older people, people with health issues, socio-economically disadvantaged people, or people undergoing more frequent extreme climatic events. While the relationship between remote Australians wellbeing and travelling activities is evident, its complexity still remains an under-researched topic. This is paradoxical when considering that extreme distances, high supply chain costs, limited access to services and to economic participation are well recognised obstacles for sustaining vibrant remote Australian communities. The latest accessibility-driven technological innovations in both the digital and the sharing economies are highly topical in transport projects in urban agglomerations but still a distant reality for remote Australia. There is a need for researching an appropriateness framework of such technologies because of the strong relevance of the multiple outcomes in terms of wellbeing that some of these innovations provide. Furthermore what defines a good quality of life can sometimes be very similar and other times greatly differ between remote and urban contexts. In the light of some recent transport and mobility research this paper analyses the potential connections between more appropriate transport innovations and increasingly resilient remote communities.

People spend most of their times in indoors such as houses, workplaces, malls, sport centers, train, transportation vehicles (train, plane, cars. In US, citizens spend nearly 100 minutes in cars per day. There are safety problems in cars except than seatbelt and airbag. Some of these are seats, furnishing, cushions for arm and head, floor covering, accessories and plastic parts. In a study conducted in Japan, more than 160 volatile organic compounds (VOC had been determined in new cars and a three years old car. Some of the pollutants are formaldehyde, toluen, xylene, ethylbenzene and styrene. Also Polybrominated diphenyl ethers (PBDEs, which may be degradated by sunshine in hot seasons are measured within the outomobiles. There is a big gap of studies about the pollutants in cars and researches have to be conducted. Manufacturers should use nonhazardous material or less toxic chemicals to reduce exposure of VOCs, PBDEs and phthalates. Drivers can reduce the these chemicals by using solar reflectors and avoiding to park under sunlight. [TAF Prev Med Bull 2010; 9(6.000: 665-672

This study is intended to understand and investigate how fuel subsidy removal policy scenarios (25%, 50%, and 100% in Jakarta affects travelers’ behavior and analyze such policy to support sustainable transport by using qualitative research methodology. Interviews and questionnaires survey is conducted to workers in Jakarta, which includes ranking scale question for traveler response options. The result shows that half of the respondents are not affected and will only respond to fuel price increasing at IDR 31,400 for gasoline price and IDR 26,300 for ADO (Auto Diesel Oil. Moreover, there is a tendency of respondent's to the response by changing their travel mode choices into more fuel efficient private vehicle.

    Background Cardiovascular events while driving have occasionally been reported. In contrast, there have been few studies on stroke while driving. Aim The objectives of this study were to (1) report the frequency of stroke while driving and (2) evaluate its association with automobile accidents. Methods Clinical data prospectively acquired between January 2011 and December 2016 on 2145 stroke patients (1301 with ischemic stroke, 585 with intracerebral hemorrhage, and 259 with subarachnoid hemorrhage) were reviewed to identify patients who sustained a stroke while driving. The ratio of driving to performing other activities was evaluated for each stroke type. Furthermore, the drivers' response to stroke was reviewed to understand how automobile accidents occurred. Results Among the 2145 patients, 85 (63 ischemic stroke, 20 intracerebral hemorrhage, and 2 subarachnoid hemorrhage) sustained a stroke while driving. The ratio of driving to performing other activities was significantly higher in ischemic stroke (4.8%) than in intracerebral hemorrhage (3.4%) or subarachnoid hemorrhage (0.8%). A majority of drivers either continued driving or pulled over to the roadside after suffering a stroke. However, 14 (16%) patients were involved in automobile accidents. In most patients, an altered mental status due to severe stroke was the presumed cause of the accident. Conclusion Stroke occurred while driving in 4.0% of all strokes and accidents occurred in 16% of these instances.

    Cities undergoing climate change and rapid urbanization are faced with significant transformational processes that affect the environment and society, challenging them to become more sustainable and resilient. The promotion of nature-based solutions represents an efficient approach to meet sustainability targets in cities and improve the quality of life of citizens. The association of large components of green infrastructure, such as urban parks, with physical activity can counteract the sedentary lifestyle endemic to cities and improve the overall health and well-being of individuals (Carrus et al., 2013; Scopelliti et al., 2016). By promoting a sustainable means of transport and connecting green spaces within a highly urbanized city, bicycle lanes represent an effective tool for associating physical activity with nature in cities allowing bicycle users to benefit from the positive health effects of nature-based solutions. Our study focuses on the potential of bicycle lanes to improve functional connectivity among green spaces. We administered 820 questionnaires in 34 green spaces (i.e., urban parks) in Bucharest, Romania, to identify the factors influencing the use of bicycle lanes connecting urban parks and to understand which planning criteria for bicycle lanes are considered as the most important by park visitors. We applied binary and ordinal logistic regressions and found that the factors affecting bicycle lane use are illegally parked cars and lack of accessibility to urban parks. The criteria preferred by park visitors for bicycle lane planning are determined by experience level and frequency of bicycle use. To develop a functional and integrated bicycle lane network that can make cities healthier and more sustainable, policy makers are advised to engage in a public participatory process and focus on the needs of bicycle users.

    The predictive methods currently used for material specification, component design and the development of manufacturing processes, need to evolve beyond the current `metal centric' state of the art, if advanced composites are to realise their potential in delivering sustainable transport solutions. There are however, significant technical challenges associated with this process. Deteriorating environmental, political, economic and social conditions across the globe have resulted in unprecedented pressures to improve the operational efficiency of the manufacturing sector generally and to change perceptions regarding the environmental credentials of transport systems in particular. There is a need to apply new technologies and develop new capabilities to ensure commercial sustainability in the face of twenty first century economic and climatic conditions as well as transport market demands. A major technology gap exists between design, analysis and manufacturing processes in both the OEMs, and the smaller companies that make up the SME based supply chain. As regulatory requirements align with environmental needs, manufacturers are increasingly responsible for the broader lifecycle aspects of vehicle performance. These include not only manufacture and supply but disposal and re-use or re-cycling. In order to make advances in the reduction of emissions coupled with improved economic efficiency through the provision of advanced lightweight vehicles, four key challenges are identified as follows: Material systems, Manufacturing systems, Integrated design methods using digital manufacturing tools and Validation systems. This paper presents a project which has been designed to address these four key issues, using at its core, a digital framework for the creation and management of key parameters related to the lifecycle performance of thermoplastic composite parts and structures. It aims to provide capability for the proposition, definition, evaluation and demonstration of

  7. Learning from experiences in sustainable transport practice: green freight europe and the implementation of a best cases database

    2015-03-01

    Full Text Available Background: For many logistics service providers and shippers sustainable transport is still a relatively recent issue, even if almost every transportation company is engaged in sustainability. Each has had different experiences with making transportation more sustainable. By looking at the efforts and successes of others sharing these experiences could help shippers and logistics service providers to obtain new innovative ideas of how to become more sustainable. The certification organization Green Freight Europe (GFE wants to develop a database for these types of experiences in order to encourage its members to generate sustainable initiatives. Method: In support of this plan, we interviewed several logistics service providers and shippers and conducted a brief survey among GFE members. Results: Sustainability forms one of the goals for all interviewed companies mainly based on cost reduction but followed closely as a tool to attract new customers. At the moment, the information obtained to keep updated on sustainability comes mainly from truck producers and not from information from best cases from other logistics service providers. Conclusions: We have found that there is a willingness to submit best cases, but also a fear that the submitter will miss his competitive advantage by telling others about his innovations.

  8. Sustainability Measures of Urban Public Transport in Cities: A World Review and Focus on the Asia/Middle East Region

    Directory of Open Access Journals (Sweden)

    Chris De Gruyter

    2016-12-01

    Full Text Available Previous studies of public transport sustainability in cities have been very limited to date, particularly in more developing countries located throughout Asia and the Middle East. This paper assesses the sustainability of urban public transport systems in cities by adopting a quantitative measurement framework containing 15 public transport sustainability indicators. It compares aggregate sustainability performance of urban public transport in international regions of cities, and then examines the relative sustainability of selected cities in the Asia and Middle East region. The world region analysis shows that Eastern Europe, Asia, and Latin America achieve the highest aggregate normalised scores for sustainable public transport, in that order. In general, the results suggest that western developed countries (Western Europe, North America, and Oceania have better performance on environmental and social indicators but poorer performance on system effectiveness and economic indicators. Asia and Latin America perform the other way round; better on economic and system effectiveness and worse on social and environmental indicators. Eastern Europe is one of the few regions with higher level performance all round. The city-based analysis of Asia/Middle East suggested that out of the 26 cities studied, the top 3 cities in terms of sustainable public transport in the Asia and Middle East Region are: 1st, Manila (Philippines; 2nd, Tokyo (Japan; and 3rd, Chennai (India. Dubai (United Arab Emirates (UAE, rated 26th, Shizuoka (Japan, rated 25th and Kuala Lumpur (Malaysia, rated 24th were the lowest rated cities. The paper explores the implications of the findings and makes suggestions for future research.

    Current tuberculosis notification rates in South Africa are among the highest ever recorded. Although the human immunodeficiency virus epidemic has been a critical factor, the density of respiratory contacts in high-risk environments may be an important and underappreciated driver. Using a modified Wells-Riley model for airborne disease transmission, we estimated the risk of tuberculosis transmission on 3 modes of public transit (minibus taxis, buses, and trains) in Cape Town, South Africa, using exhaled carbon dioxide as a natural tracer gas to evaluate air exchange. Carbon dioxide measurements were performed between October and December of 2011. Environmental risk, reflected in the rebreathed fraction of air, was highest in minibus taxis and lowest in trains; however, the average number of passengers sharing an indoor space was highest in trains and lowest in minibus taxis. Among daily commuters, the annual risk of tuberculosis infection was projected to be 3.5%-5.0% and was highest among minibus taxi commuters. Assuming a duration of infectiousness of 1 year, the basic reproductive number attributable to transportation was more than 1 in all 3 modes of transportation. Given its poor ventilation and high respiratory contact rates, public transportation may play a critical role in sustaining tuberculosis transmission in South African cities.

    In the present article, the results of geotechnical monitoring of A-147 automobile road “Dzhubga-Sochi” are given. Some sections of the automobile road suffered from the landslide adjustment movements; it resulted in many deformations of the retaining structures, the damages of the roadbed and ground crawling over the retaining walls. The observation data made it possible to specify the borders of the active landslide and to form a forecast of the landslide activity in the sections of the automobile roads. Due to monitoring being carried out, there was substantiated the necessity to correct the service forms and records connected with the automobile road reconstruction.

    This paper present the BEST project - Bio Ethanol for Sustainable Transport, that aims to promote the ethanol usage, replacing diesel, in the urban public transport in Brazil and worldwide. Apart from Sao Paulo, leading city in the Americas, another eight cities located in Europe and Asia takes part in the project. One of the Brazilian project's goals is to evaluate ethanol usage as diesel fuel replacement in public transport buses by comparatively following the operational output of the experimental fleet, taking as reference an equivalent diesel bus. The utilized test vehicles will be evaluated and monitored to demonstrate ethanol energetic efficiency and, after the results the BEST project and the European Union will set a blue print for public policies to incentive ethanol usage in the urban public transport. The results will allow identifying technical and economical barriers that will eventually overlap the viability process of this technology in the Brazilian public transport. (author)

    The return of sunlight in the polar spring leads to the production of reactive halogen species from the surface snowpack, significantly altering the chemical composition of the Arctic near-surface atmosphere and the fate of long-range transported pollutants, including mercury. Recent work has shown the initial production of reactive bromine at the Arctic surface snowpack; however, we have limited knowledge of the vertical extent of this chemistry, as well as the lifetime and possible transport of reactive bromine aloft. Here, we present bromine monoxide (BrO) and aerosol particle measurements obtained during the March 2012 BRomine Ozone Mercury EXperiment (BROMEX) near Utqiaġvik (Barrow), AK. The airborne differential optical absorption spectroscopy (DOAS) measurements provided an unprecedented level of spatial resolution, over 2 orders of magnitude greater than satellite observations and with vertical resolution unable to be achieved by satellite methods, for BrO in the Arctic. This novel method provided quantitative identification of a BrO plume, between 500 m and 1 km aloft, moving at the speed of the air mass. Concurrent aerosol particle measurements suggest that this lofted reactive bromine plume was transported and maintained at elevated levels through heterogeneous reactions on colocated supermicron aerosol particles, independent of surface snowpack bromine chemistry. This chemical transport mechanism explains the large spatial extents often observed for reactive bromine chemistry, which impacts atmospheric composition and pollutant fate across the Arctic region, beyond areas of initial snowpack halogen production. The possibility of BrO enhancements disconnected from the surface potentially contributes to sustaining BrO in the free troposphere and must also be considered in the interpretation of satellite BrO column observations, particularly in the context of the rapidly changing Arctic sea ice and snowpack.

    Physical inactivity is one of the leading risk factors for non-communicable diseases, yet many are not sufficiently active. The Physical Activity through Sustainable Transport Approaches (PASTA) study aims to better understand active mobility (walking and cycling for transport solely or in combination with public transport) as an innovative approach to integrate physical activity into individuals' everyday lives. The PASTA study will collect data of multiple cities in a longitudinal cohort design to study correlates of active mobility, its effect on overall physical activity, crash risk and exposure to traffic-related air pollution. A set of online questionnaires incorporating gold standard approaches from the physical activity and transport fields have been developed, piloted and are now being deployed in a longitudinal study in seven European cities (Antwerp, Barcelona, London, Oerebro, Rome, Vienna, Zurich). In total, 14000 adults are being recruited (2000 in each city). A first questionnaire collects baseline information; follow-up questionnaires sent every 13 days collect prospective data on travel behaviour, levels of physical activity and traffic safety incidents. Self-reported data will be validated with objective data in subsamples using conventional and novel methods. Accelerometers, GPS and tracking apps record routes and activity. Air pollution and physical activity are measured to study their combined effects on health biomarkers. Exposure-adjusted crash risks will be calculated for active modes, and crash location audits are performed to study the role of the built environment. Ethics committees in all seven cities have given independent approval for the study. The PASTA study collects a wealth of subjective and objective data on active mobility and physical activity. This will allow the investigation of numerous correlates of active mobility and physical activity using a data set that advances previous efforts in its richness, geographical coverage

    Only one-third of the European population meets the minimum recommended levels of physical activity (PA). Physical inactivity is a major risk factor for non-communicable diseases. Walking and cycling for transport (active mobility, AM) are well suited to provide regular PA. The European research project Physical Activity through Sustainable Transport Approaches (PASTA) pursues the following aims: (1) to investigate correlates and interrelations of AM, PA, air pollution and crash risk; (2) to evaluate the effectiveness of selected interventions to promote AM; (3) to improve health impact assessment (HIA) of AM; (4) to foster the exchange between the disciplines of public health and transport planning, and between research and practice. PASTA pursues a mixed-method and multilevel approach that is consistently applied in seven case study cities. Determinants of AM and the evaluation of measures to increase AM are investigated through a large scale longitudinal survey, with overall 14,000 respondents participating in Antwerp, Barcelona, London, Örebro, Rome, Vienna and Zurich. Contextual factors are systematically gathered in each city. PASTA generates empirical findings to improve HIA for AM, for example, with estimates of crash risks, factors on AM-PA substitution and carbon emissions savings from mode shifts. Findings from PASTA will inform WHO's online Health Economic Assessment Tool on the health benefits from cycling and/or walking. The study's wide scope, the combination of qualitative and quantitative methods and health and transport methods, the innovative survey design, the general and city-specific analyses, and the transdisciplinary composition of the consortium and the wider network of partners promise highly relevant insights for research and practice. Ethics approval has been obtained by the local ethics committees in the countries where the work is being conducted, and sent to the European Commission before the start of the survey.

    Full Text Available This paper is a brief overview of the evolution of the global automotive industry during the 20th century, with reference to the main manufacturers, oil crises of 1970-1980, and also the global financial and economic crisis that began in 2008. The analyzed period covers the rise of the Asian Continent, beginning with Japan, then South Korea and more recently the emerging countries: China and India. What was predicted 20-25 years ago, became reality: Asia becomes the economic centre of the world, surpassing unexpectedly fast even the Euro-Atlantic area. Regarding Romania, the revival delay of the automobiles industry, led to the loss of the trucks and bus industry, and after a much awaited rehabilitation of car production, this has stuck now at an unsatisfactory level.

    Full Text Available Intelligent transportation systems mostly operate on information exchange principle between vehicles and roadside infrastructure. They are commonly regarded as a base technology for persistent diminution of road accidents and traffic efficiency increase. However, intelligent transportation systems can also be used at all levels of transportation systems as a basis for stable development of cities, enterprises, regions, states, continents. According to the research, the existing intelligent transportation systems not only provide the considerable reduction of greenhouse gases emissions, fuel saving, time of travel cutting, but they don’t marginalize citizens’ mobility as well. Thus, the further development and introduction of modern transportation innovative technologies will allow to guarantee the energy- and resources efficiency and, therefore, the sustainable development of the whole society.

  5. A Life-Cycle Comparison of Alternative Automobile Fuels.

    We examine the life cycles of gasoline, diesel, compressed natural gas (CNG), and ethanol (C2H5OH)-fueled internal combustion engine (ICE) automobiles. Port and direct injection and spark and compression ignition engines are examined. We investigate diesel fuel from both petroleum and biosources as well as C2H5OH from corn, herbaceous bio-mass, and woody biomass. The baseline vehicle is a gasoline-fueled 1998 Ford Taurus. We optimize the other fuel/powertrain combinations for each specific fuel as a part of making the vehicles comparable to the baseline in terms of range, emissions level, and vehicle lifetime. Life-cycle calculations are done using the economic input-output life-cycle analysis (EIO-LCA) software; fuel cycles and vehicle end-of-life stages are based on published model results. We find that recent advances in gasoline vehicles, the low petroleum price, and the extensive gasoline infrastructure make it difficult for any alternative fuel to become commercially viable. The most attractive alternative fuel is compressed natural gas because it is less expensive than gasoline, has lower regulated pollutant and toxics emissions, produces less greenhouse gas (GHG) emissions, and is available in North America in large quantities. However, the bulk and weight of gas storage cylinders required for the vehicle to attain a range comparable to that of gasoline vehicles necessitates a redesign of the engine and chassis. Additional natural gas transportation and distribution infrastructure is required for large-scale use of natural gas for transportation. Diesel engines are extremely attractive in terms of energy efficiency, but expert judgment is divided on whether these engines will be able to meet strict emissions standards, even with reformulated fuel. The attractiveness of direct injection engines depends on their being able to meet strict emissions standards without losing their greater efficiency. Biofuels offer lower GHG emissions, are sustainable, and

    Cost control must be implemented through the establishment of requirements and controlled continually by managing to these requirements. Cost control of the non-recurring side of life cycle cost has traditionally been implemented in both commercial and government programs. The government uses the budget process to implement this control. The commercial approach is to use a similar process of allocating the non-recurring cost to major elements of the program. This type of control generally manages through a work breakdown structure (WBS) by defining the major elements of the program. If the cost control is to be applied across the entire program life cycle cost (LCC), the approach must be addressed very differently. A functional breakdown structure (FBS) is defined and recommended. Use of a FBS provides the visibifity to allow the choice of an integrated solution reducing the cost of providing many different elements of like function. The different functional solutions that drive the hardware logistics, quantity of documentation, operational labor, reliability and maintainability balance, and total integration of the entire system from DDT&E through the life of the program must be fully defined, compared, and final decisions made among these competing solutions. The major drivers of recurring cost have been identified and are presented and discussed. The LCC requirements must be established and flowed down to provide control of LCC. This LCC control will require a structured rigid process similar to the one traditionally used to control weight/performance for space transportation systems throughout the entire program. It has been demonstrated over the last 30 years that without a firm requirement and methodically structured cost control, it is unlikely that affordable and sustainable space transportation system LCC will be achieved.

    Over the last three decades, automobile manufacturers have made a lot of progress in specific fuel consumption and engine emissions of pollutants. Yet the impact of these improvements on vehicle consumption has been limited by increased dynamic performances (maxi-mum speed, torque), increased safety (power steering and power brakes) and increased comfort (noise and vibration reduction, electric windows and thermal comfort). Because of this, the real CO{sub 2}-emission levels in vehicles is still high in a context where road transport is a major factor in the balance sheet of greenhouse gas emissions, thus in complying with the inter-national climate convention. Although European, Japanese and Korean manufacturers signed an important agreement with the European Commission for voluntarily reducing CO{sub 2} emissions from their vehicles, with a weighted average emission goal by sales of 140 grams per km on the MVEG approval cycle by 2008, it has to be noted that the European procedures for measuring fuel consumption and CO{sub 2} emissions do not take accessories into account, especially air-condition ng (A/C). The big dissemination of this equipment recognized as a big energy consumer and as using a refrigerant with a high global warming potential ed ADEME to implement a set of assessments of A/C's energy and environmental impact. In particular these assessments include studies of vehicle equipment rates, analyses of impact on fuel consumption as well as regulated pollutant emissions in the exhaust, a characterization of the refrigerant leakage levels and an estimate of greenhouse gas emissions for all air-conditioned vehicles. This leaflet summarizes the results of these actions. All of these studies and additional data are presented in greater detail in the document,-'Automobile Air-conditioning' (ADEME reference no. 4985). (author)

    Environmental sustainability and green environmental issues have an increasing popularity among researchers and supply chain practitioners. An attempt has been made to identify and empirically analyze green supply chain management (GSCM) practices in Indian automobile industry. Six main GSCM practices (having 37 sub practices) and four expected performance outcomes (having 16 performances) have been identified by implementing GSCM practices from literature review. Questionnaire based survey has been made to validate these practices and performance outcomes. 123 complete questionnaires were collected from Indian automobile organizations and used for empirical analysis of GSCM practices in Indian automobile industry. Descriptive statistics have been used to know current implementation status of GSCM practices in Indian automobile industry and multiple regression analysis has been carried out to know the impact on expected organizational performance outcomes by current GSCM practices adopted by Indian automobile industry. The results of study suggested that environmental, economic, social and operational performances improve with the implementation of GSCM practices. This paper may play an important role to understand various GSCM implementation issues and help practicing managers to improve their performances in the supply chain.

  14. Individualized solutions to environmental problems: a case of automobile pollution

    Air pollution associated with motor vehicle use is one of the prime indicators of the tension between consumerism and the environment. The use of private automobiles seems so convenient, whereas the alternatives are off-putting enough to make significant changes in personal transportation behaviour well-nigh impossible. At the same time, combating the air pollution associated with extensive use of cars has become one of the major policy objectives for cities around the world. Available policy alternatives can be divided into two categories: (1) incentives, such as improved public transportation, and (2) disincentives, such as environmental tax on gasoline. This paper attempt to directly assess links between these two alternatives, associated attitudes towards them, the level of public support for command and control (i.e. regulatory) policy approaches as well as for economic incentive/disincentive policies. Answers are sought and findings discussed relative to the link between opinions about the environment and support for different types of environmental policies, the usefulness of a rational choice perspective in explaining support for environmental policy alternatives, the role that partisan political attachments play in support of environmental policy approaches, and the roles played by environmental activism, knowledge, and action in shaping support for environmental policy alternatives. Overall results indicate that while most people living in urban environments support the ideas of environmental protection and would be willing to incur costs to confront the problem, exposure to air pollution plays an inconsequential (actually nearly non-existent) role in support of automobile-related environmental problems. Automobile users act like 'free-riders' i.e. they tend to support policies that socialize the cost of solutions rather than policies that attempt to pass the cost of pollution directly on to individual car owners.

    Automobile mechanics have been exposed to asbestos in the past, mainly due to the presence of chrysotile asbestos in brakes and clutches. Despite the large number of automobile mechanics, little is known about the non-malignant respiratory diseases observed in this population. The aim of this retrospective multicenter study was to analyse the frequency of pleural and parenchymal abnormalities on high-resolution computed tomography (HRCT) in a population of automobile mechanics. The study population consisted of 103 automobile mechanics with no other source of occupational exposure to asbestos, referred to three occupational health departments in the Paris area for systematic screening of asbestos-related diseases. All subjects were examined by HRCT and all images were reviewed separately by two independent readers; who in the case of disagreement discussed until they reached agreement. Multiple logistic regression models were constructed to investigate factors associated with pleural plaques. Pleural plaques were observed in five cases (4.9%) and interstitial abnormalities consistent with asbestosis were observed in one case. After adjustment for age, smoking status, and a history of non-asbestos-related respiratory diseases, multiple logistic regression models showed a significant association between the duration of exposure to asbestos and pleural plaques. The asbestos exposure experienced by automobile mechanics may lead to pleural plaques. The low prevalence of non-malignant asbestos-related diseases, using a very sensitive diagnostic tool, is in favor of a low cumulative exposure to asbestos in this population of workers.

  1. Physiological Functions of Cyclic Electron Transport Around Photosystem I in Sustaining Photosynthesis and Plant Growth.

    Science.gov (United States)

    Yamori, Wataru; Shikanai, Toshiharu

    2016-04-29

    The light reactions in photosynthesis drive both linear and cyclic electron transport around photosystem I (PSI). Linear electron transport generates both ATP and NADPH, whereas PSI cyclic electron transport produces ATP without producing NADPH. PSI cyclic electron transport is thought to be essential for balancing the ATP/NADPH production ratio and for protecting both photosystems from damage caused by stromal overreduction. Two distinct pathways of cyclic electron transport have been proposed in angiosperms: a major pathway that depends on the PROTON GRADIENT REGULATION 5 (PGR5) and PGR5-LIKE PHOTOSYNTHETIC PHENOTYPE 1 (PGRL1) proteins, which are the target site of antimycin A, and a minor pathway mediated by the chloroplast NADH dehydrogenase-like (NDH) complex. Recently, the regulation of PSI cyclic electron transport has been recognized as essential for photosynthesis and plant growth. In this review, we summarize the possible functions and importance of the two pathways of PSI cyclic electron transport.

    1994-01-01

    Transportation network capacity variations arising from accidents, roadway maintenance activity, and special events as well as fluctuations in commuters' travel demands complicate traffic management. Artificial intelligence concepts and expert systems can be useful in framing policies for incident detection, congestion anticipation, and optimal traffic management. This paper examines the applicability of intelligent route guidance and control as decision aids for traffic management. Basic requirements for managing traffic are reviewed, concepts for studying traffic flow are introduced, and mathematical models for modeling traffic flow are examined. Measures for quantifying transportation network performance levels are chosen, and surveillance and control strategies are evaluated. It can be concluded that automated decision support holds great promise for aiding the efficient flow of automobile traffic over limited-access roadways, bridges, and tunnels.

  9. The impact of transport infrastructure projects on sustainable development within a major logistics gateway in North West England

    2016-10-01

    Full Text Available In the North West of England the issue of a perceived infrastructure gap is of increasing concern. Investment needs to be made to improve the transport infrastructure of the region if it is to be expected to promote the development of its own regional logistics gateway. Funding tools have been set up to address the challenges arising from the imbalance in infrastructure development that exists between regions in the north of the United Kingdom and those in the south. For regions with well developed economies the outlook is promising as the availability of modern transport infrastructure looks set to improve. However, some sources believe that the development of new transport infrastructure will have a negative impact upon sustainable development. It is expected that this will occur in a range of both direct and indirect ways. As a result, it is critical that planning for the creation of new intermodal transport infrastructure, or the upgrading of that which already exists, takes into account the impact that these developments will have on the sustainable development of the host region. A scenario based development methodology is proposed in this paper. It was developed to provide a way to identify potential scenarios that may arise within a given region as a result of transport infrastructure projects. To create significant scenarios the methodology is dependent on the availability of a sufficient quantity of quality data. For this paper that data was collected through a focus group composed of stakeholders from the region in question. This was further supported by the performance of an impact survey using the same group of stakeholders.

    The study focused to assess the level of efficiency (of both emissions and service quality) that can be achieved for the transport system in Dhaka City, Bangladesh. The assessment technique attempted to quantify the extent of eco-efficiency achievable for the system modifications due to planning or strategy. The eco-efficiency analysis was facilitated with a detailed survey data on Dhaka City transport system, which was conducted for 9 months in 2012-2013. Line source modelling (CALINE4) was incorporated to estimate the on-road emission concentration. The eco-efficiency of the transport systems was assessed with the 'multi-criteria analysis' (MCA) technique that enabled the valuation of systems' qualitative and quantitative parameters. As per the analysis, driving indiscipline on road can alone promise about 47% reductions in emissions, which along with the number of private vehicles were the important stressors that restrict achieving eco-efficiency in Dhaka City. Detailed analysis of the transport system together with the potential transport system scenarios can offer a checklist to the policy makers enabling to identify the possible actions needed that can offer greater services to the dwellers against lesser emissions, which in turn can bring sustainability of the system.

    Single occupancy vehicle (SOV) transportation is a key contributor to climate change and air pollution. Sustainable transportation (ST), commuting by any means other than SOV, could both slow climate change and enhance public health. The transtheoretical model (TTM) provides a useful framework for examining how people progress towards adopting ST. Short valid and reliable measures for ST decisional balance, self-efficacy, and climate change doubt were developed and their relationship with stages of change was examined. Two large university-based volunteer samples participated in measurement studies. Using multiple procedures, three brief internally consistent measures were developed: decisional balance, self-efficacy, and climate change doubt. The stages of change correctly discriminated both decisional balance and self-efficacy, as well as replicated hypothesized relationships. Climate change doubt did not vary by stages; however, it may prove useful in future studies. Results support the validation of these measures and the application of the TTM to ST.

    The article explains the role of public transport pricing. It proves the need for a systemic approach to building a modern public transit system. The authors argue that the main objective of the approach should be to reduce the use of private vehicles in the urban environment and increasing public transport use. It is proven that for the consumer of transport services the price per trip is an important factor when deciding whether to travel by car or by public transport. The authors analyze the available literature assessing the effects of widespread car ownership on users of the city transit system. Conflict situations that occur due to the unabated desire of city residents to travel by car are analyzed. A research method is proposed. It is shown that public transport fares have been growing in Russia at an accelerated pace when compared to the overall increase in prices of all goods and services, including motor vehicles, petrol and oils. The fare growth has resulted in a 3.6 fold drop in demand for public transport services over the 15 years being analyzed. Over the same period, the number of privately owned cars grew 120 percent. A conclusion is drawn that regular fare hikes have encouraged urban population to gradually opt against travelling by public transport. That resulted in higher demand for car travel and, eventually, in an accelerated growth in car usage. One can conclude that a persistent institutional trap has taken shape in Russian metropolises. Essentially, it means that higher public transport fares have led to lower demand for public transit services. As ridership goes down, public transport operators have to again increase prices, thus driving the demand for their services down. It is proven that escaping the trap will require restoring the ratio of prices to make sure that the price charged for a public transport trip is far lower than the cost of travelling by car. The aim of this study is to assess the influence of the factor of public

    The reduced pool of the ABA precursors, β,β-carotenoids, in roots does not account for the substantial increase in ABA content in response to water stress (WS) conditions, suggesting that ABA could be transported from other organs. Basipetal transport was interrupted by stem-girdling, and ABA levels were determined in roots after two cycles of WS induced by transplanting plants to dry perlite. Leaf applications of isotope-labeled ABA and reciprocal grafting of ABA-deficient tomato mutants were used to confirm the involvement of aerial organs on root ABA accumulation. Disruption of basipetal transport reduced ABA accumulation in roots, and this decrease was more severe after two consecutive WS periods. This effect was linked to a sharp decrease in the β,β-carotenoid pool in roots in response to water deficit. Significant levels of isotope-labeled ABA were transported from leaves to roots, mainly in plants subjected to water dehydration. Furthermore, the use of different ABA-deficient tomato mutants in reciprocal grafting combinations with wild-type genotypes confirmed the involvement of aerial organs in the ABA accumulation in roots. In conclusion, accumulation of ABA in roots after long-term WS periods largely relies on the aerial organs, suggesting a reduced ability of the roots to synthesize ABA from carotenoids. Furthermore, plants are able to transport ABA basipetally to sustain high hormone levels in roots. © The Author 2015.

    2008-01-01

    Full Text Available An automotive air-conditioning system based on absorption refrigeration cycle has been simulated. This waste heat driven vapor absorption refrigeration system is one alternate to the currently used vapour compression refrigeration system for automotive air-conditioning. Performance analysis of vapor absorption refrigeration system has been done by developing a steady-state simulation model to find the limitation of the proposed system. The water-lithium bromide pair is used as a working mixture for its favorable thermodynamic and transport properties compared to the conventional refrigerants utilized in vapor compression refrigeration applications. The pump power required for the proposed vapor absorption refrigeration system was found lesser than the power required to operate the compressor used in the conventional vapor compression refrigeration system. A possible arrangement of the absorption system for automobile application is proposed.

    Sustainable land public transportation (SLPT) aims to promote a better and healthier ways of meeting individual and community needs. Even though sufficient land public transportation have been provided at Ayer Keroh, Malacca but the level of usage among the community is still low as there is the growth in traffic. Hang Tuah Jaya Municipal Council (HTJMC) is responsible to identify the most appropriate strategies to manage the issues regarding SLPT in order to support of the Malacca state vision becoming Green Technology State in the year 2020. Therefore, this paper attempts to examine the strategies involve in building a SLPT, which may enhance the community's welfare. Thus, the proposed theoretical framework is to demonstrate the strategies towards building a SLPT, which can cater issues within the municipal council area. In this qualitative research, an in-depth focus group have been conducted to obtain the primary data. Thirteen (13) executives from HTJMC involved. This study brings a new paradigm in transforming land public transportation at Ayer Keroh to enhance the community welfare. The result found that land use development as the most significant strategy in SLPT, meanwhile the implementation program is the least strategy involved in building a SLPT at Ayer Keroh. Future research requires more information on the factors of implementing of SLPT so that HTJMC can plan an effective SLPT thorough the demand as the data may indicate numbers of passengers who really support to the implementation of SLPT.

  9. Analytical decision-making methods for evaluating sustainable transport in European corridors

    CERN Document Server

    2014-01-01

    Eurocorridors are characterized by intensive transport flows and dynamic patterns of establishment and household locations. They are also considered the backbones of powerful spatial and economic forces in the areas that connect urban regions. One of the main difficulties in the spatial planning of eurocorridors has been the need to engage in different types of collective action. Such an approach can be extremely challenging in practice, useful to researchers in the field and to professionals as well. In the light of this, the book’s main objectives are:  - To define the problem by analyzing the key features, which include freight and passenger transport policies and issues; the territorial context, with its geographical, social, economic and cultural aspects; the plurality of subjects with different aims and resources and the lack of homogeneous information. - To illustrate assessment models and evaluation frameworks (MCDA; Discrete Choice Analysis; Collaborative Assessments; Geovisualization Technologi...

    2017-10-01

    The article proposes the models of innovative activity development, which is driven by the formation of “points of innovation-driven growth”. The models are based on the analysis of the current state and dynamics of innovative development of construction enterprises in the transport sector and take into account a number of essential organizational and economic changes in management. The authors substantiate implementing such development models as an organizational innovation that has a communication genesis. The use of the communication approach to the formation of “points of innovation-driven growth” allowed the authors to apply the mathematical tools of the graph theory in order to activate the innovative activity of the transport industry in the region. As a result, the authors have proposed models that allow constructing an optimal mechanism for the formation of “points of innovation-driven growth”.

    Full Text Available Background : Automobile repair shop is a place where workers are exposed to harmful chemicals and toxic substances. Objective : To study the occurrence of obstructive and restrictive pulmonary impairment among automobile garage workers. Methods : A cross sectional study involving 151 automobile garage workers from 14 randomly selected garages of urban Kolkata. The study variables were Forced Expiratory Volume in 1 second (FEV 1 , Forced Vital Capacity (FVC, Peak Expiratory Flow Rate (PE FR, age, smoking habit, duration of work, type of work, and respiratory symptoms. The study was analysed using Regression equations, and Chi-square test. Results : All the workers were male. Obstructive impairment was seen in 25.83% of the workers whereas restrictive impairment was seen in 21.19% of the workers. Mixed obstructive and restrictive impairment was seen in 10.6% of the workers. The frequency of obstructive impairment was higher in older workers. In the age group of less than 20 years, 13.6% of the workers had obstructive impairment while 42.86% of workers above 40 years of age had obstructive impairment. Obstructive impairment was more frequently observed in battery repair workers (58.33% and spray painters (37.5% while 16.67% of the body repair workers and 30.19% of the engine mechanics had obstructive impairment. Obstructive impairment was more frequently observed in smokers (53.1 % as compared to ex-smokers (33.3% and non-smokers (6.4%. Obstructive impairment was more frequently observed in workers who had been working for a longer duration. Conclusion: Nearly 36.4% of the automobile garage workers had some form of pulmonary function impairment; obstructive and/or restrictive. The use of personal protective equipment, worker education, and discontinuation of the use of paints containing toxic pigments are recommended.

  13. Solute transport characterization in karst aquifers by tracer injection tests for a sustainable water resource management

    Morales, T.; Angulo, B.; Uriarte, J. A.; Olazar, M.; Arandes, J. M.; Antiguedad, I.

    2017-04-01

    Protection of water resources is a major challenge today, given that territory occupation and land use are continuously increasing. In the case of karst aquifers, its dynamic complexity requires the use of specific methodologies that allow establishing local and regional flow and transport patterns. This information is particularly necessary when springs and wells harnessed for water supply are concerned. In view of the present state of the art, this work shows a new approach based on the use of a LiCl based tracer injection test through a borehole for transport characterization from a local to a regional scale. Thus a long term tracer injection test was conducted in a particularly sensitive sector of the Egino karst massif (Basque Country, Spain). The initial displacement of tracer in the vicinity of the injection was monitored in a second borehole at a radial distance of 10.24 m. This first information, assessed by a radial divergent model, allows obtaining transport characteristic parameters in this immediate vicinity during injection. At a larger (regional) scale, the tracer reaches a highly transmissive network with mean traveling velocities to the main springs being from 4.3 to 13.7 m/h. The responses obtained, particularly clear in the main spring used for water supply, and the persistence of part of the tracer in the injection zone, pose reconsidering the need for their protection. Thus, although the test allows establishing the 24-h isochrone, which is the ceiling value in present European vulnerability approaches, the results obtained advise widening the zone to protect in order to guarantee water quality in the springs. Overall, this stimulus-response test allows furthering the knowledge on the dynamics of solute transport in karst aquifers and is a particularly useful tool in studies related to source vulnerability and protection in such a complex medium.

    Climate change is a problem that must be solved. The primary cause of this problem is burning of fossil fuels to generate energy. A dramatic reduction in carbon emissions must happen soon, and a significant fraction of this reduction must come from the transportation sector. This paper reviews existing literature to assess the consensus of the scientific and engineering communities concerning the potential for the United States' light-duty transportation sector to meet a goal of 80 percent reduction in vehicle emissions and examine what it will take to meet this target. It is unlikely that reducing energy consumption in just vehicles with gasoline-based internal combustion drivetrains will be sufficient to meet GHG emission-reduction targets. This paper explores what additional benefits are possible through the adoption of alternative energy sources, looking at three possible on-vehicle energy carriers: carbon-based fuels, hydrogen, and batteries. potential for the United States' light-duty transportation sector to meet a goal of 80 percent reduction in vehicle emissions and examine what it will take to meet this target.

    Potassium (K) and phosphate (Pi) are both macronutrients essential for plant growth and crop production, but the unrenewable resources of phosphorus rock and potash have become limiting factors for food security. One critical measure to help solve this problem is to improve nutrient use efficiency (NUE) in plants by understanding and engineering genetic networks for ion uptake, translocation, and storage. Plants have evolved multiple systems to adapt to various nutrient conditions for growth and production. Within the NUE networks, transport proteins and their regulators are the primary players for maintaining nutrient homeostasis and could be utilized to engineer high NUE traits in crop plants. A large number of publications have detailed K+ and Pi transport proteins in plants over the past three decades. Meanwhile, the discovery and validation of their regulatory mechanisms are fast-track topics for research. Here, we provide an overview of K+ and Pi transport proteins and their regulatory mechanisms, which participate in the uptake, translocation, storage, and recycling of these nutrients in plants. © The Author 2016.

  19. Thermal energy storage for the Stirling engine powered automobile. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Morgan, D T [ed.

    1979-03-01

    A detailed design of a thermal energy storage (TES) system for use with the Stirling engine as an automotive power system has been developed. The gravimetric and volumetric storage densities are competitive with electric battery storage systems. The TES/Stirling engine system meets all operational requirements for a practical vehicle and can be packaged in compact-sized automobiles with minimum impact on passenger and freight volume. The TES/Stirling system is the only storage approach for direct use of combustion heat from fuel sources not suitable for direct transport and use on the vehicle. The particular concept developed in this study is also useful for a dual-mode TES/liquid fuel system in which the TES (recharged from an external energy source) is used for short-duration trips (approx. 10 miles or less) and liquid fuel carried onboard the vehicle used for long-duration trips (as in current automobiles). The dual-mode approach permits an automobile with the convenience and flexibility of current automobiles while offering the potential of 50% savings in the consumption of premium liquid fuels for automotive propulsion in the United States. Relative to the TES-only vehicle, the dual mode approach also reduces the TES cost significantly because of the much smaller TES capacity required.

    European maritime companies have adopted programs to limit operational impacts on the environment. For maritime companies in North America, the Green Marine Environmental Program (GMEP) offers a framework to establish and reduce environmental footprints. Green Marine (GM) participants demonstrate annual improvements of specific environmental performance indicators (e.g., reductions in air pollution emissions) to maintain certification. Participants complete annual self-evaluations with results determining rankings for performance indicators on a 1-to-5 scale. Self-evaluations are independently verified every two years to ensure rigor and individual results are made publicly available annually to achieve transparency. GM benefits the marine industry across North America by encouraging sustainable development initiatives. GM's credibility is reflected through a diverse network of environmental groups and government agencies that endorse and help shape the program. Merits of this relatively new maritime certification (not previously described in the academic literature), are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    A necessary prerequisite of cloud formation, aerosol particles represent one of the largest uncertainties in computer simulations of climate change1,2, in part because of a poor understanding of processes under natural conditions3,4. The Amazon rainforest is one of the few continental regions where aerosol particles and their precursors can be studied under near-natural conditions5-7. Cloud condensation nuclei (CCN) in clean Amazonia are mostly produced by the growth of smaller particles in the boundary layer8-10, whereas these smaller particles themselves 31 appear to be produced elsewhere5,11. Key questions are in what part of the atmosphere they might 32 be produced and what could be the transport processes that deliver them to the boundary layer, where they grow into CCN. Here, using recent aircraft measurements above central Amazonia, we show high concentrations of small particles in the lower free troposphere. The particle size spectrum shifts towards larger sizes with decreasing altitude, implying particle growth as air descends from the free troposphere towards Earth's surface. Complementary measurements at ground sites show that free tropospheric air having high concentrations of small particles (diameters of less than 50 nm) is transported into the boundary layer during precipitation events, both by strong convective downdrafts and by weaker downward motions in the trailing stratiform region. This vertical transport helps maintain the population of small particles and ultimately CCN in the boundary layer, thereby playing an important role in controlling the climate state under natural conditions. In contrast, this mechanism becomes masked under polluted conditions, which sometimes prevail at times in Amazonia as well as over other tropical continental regions5,12.

    Ultraclean fuels production has become increasingly important as a method to help decrease emissions and allow the introduction of alternative feed stocks for transportation fuels. Established methods, such as Fischer-Tropsch, have seen a resurgence of interest as natural gas prices drop and existing petroleum resources require more intensive clean-up and purification to meet stringent environmental standards. This review covers some of the advances in deep desulfurization, synthesis gas conversion into fuels and feed stocks that were presented at the 245th American Chemical Society Spring Annual Meeting in New Orleans, LA in the Division of Energy and Fuels symposium on "Ultraclean Fuels Production and Utilization".

    The nucleation of atmospheric vapours is an important source of new aerosol particles that can subsequently grow to form cloud condensation nuclei in the atmosphere. Most field studies of atmospheric aerosols over continents are influenced by atmospheric vapours of anthropogenic origin (for example, ref. 2) and, in consequence, aerosol processes in pristine, terrestrial environments remain poorly understood. The Amazon rainforest is one of the few continental regions where aerosol particles and their precursors can be studied under near-natural conditions, but the origin of small aerosol particles that grow into cloud condensation nuclei in the Amazon boundary layer remains unclear. Here we present aircraft- and ground-based measurements under clean conditions during the wet season in the central Amazon basin. We find that high concentrations of small aerosol particles (with diameters of less than 50 nanometres) in the lower free troposphere are transported from the free troposphere into the boundary layer during precipitation events by strong convective downdrafts and weaker downward motions in the trailing stratiform region. This rapid vertical transport can help to maintain the population of particles in the pristine Amazon boundary layer, and may therefore influence cloud properties and climate under natural conditions.

    This paper reports the estimation of transportation energy consumption based on the travel behaviour characteristics of the population in the Engineering Campus, Universiti Sains Malaysia. The travel behaviour characteristics include the travel distance, travel speed, number of trips per day, and modal share of the transport, which only focused on the trips that were made inside the campus. The travel behaviour data were collected through online and pencil-and-paper questionnaire survey involving 1000 respondents including staffs and students, which is equivalent to 25% of the total population. The result from the survey showed that a total of 1897 trips per day were made by the motorised vehicle owners including car and motorcycle owners. The total trip length per day was 1056.29 km with an average speed of 45km/h. The average trip for each person was four trips per day. The estimate energy consumption from the motorised vehicles in this campus was reported to be 1.25E9 MJ.

    Full Text Available Developing public transportation and giving priority to buses is a feasible solution for improving the level of public transportation service, which facilitates congestion alleviation and prevention, and contributes to urban development and city sustainability. This paper presents a novel bus operation control strategy including both holding control and speed control to improve the level of service of transit systems within a connected vehicle environment. Most previous work focuses on optimization of signal timing to decrease the bus signal delay by assuming that holding control is not applied; the speed of buses is given as a constant input and the acceleration and deceleration processes of buses can be neglected. This paper explores the benefits of a bus operation control strategy to minimize the total cost, which includes bus signal delay, bus holding delay, bus travel delay, acceleration cost due to frequent stops and intense driving. A set of formulations are developed to explicitly capture the interaction between bus holding control and speed control. Experimental analysisand simulation tests have shown that the proposed integrated operational model outperforms the traditional control, speed control only, or holding control only strategies in terms of reducing the total cost of buses. The sensitivity analysis has further demonstrated the potential effectiveness of the proposed approach to be applied in a real-time bus operation control system under different levels of traffic demand, bus stop locations, and speed limits.

    As emissions from automobiles steadily increase, Transportation Demand Management (TDM) is becoming a critical component of regional or local transportation strategies. The Regional Municipality of Peel was motivated to update its regional TDM policies to address the problem of traffic congestion and to create a sustainable community. This workshop provided an opportunity for major employers, provincial and municipal staff and other stakeholders to discuss TDM policies and programs. It provided opportunities to create public/private partnerships to manage transportation demand. TDM maximizes the use of existing transportation infrastructure and investment. TDM also reduces traffic congestion, improves personal mobility and facilitates employee retention. The workshop featured 6 presentations, of which 3 have been indexed separately for inclusion in this database. refs., tabs., figs.

    Reducing greenhouse gas emissions (GHG) is an important social goal to mitigate climate change. A common mitigation paradigm is to consider strategy "wedges" that can be applied to different activities to achieve desired GHG reductions. In this policy analysis piece, we consider a wide range of possible strategies to reduce light-duty vehicle GHG emissions, including fuel and vehicle options, low carbon and renewable power, travel demand management and land use changes. We conclude that no one strategy will be sufficient to meet GHG emissions reduction goals to avoid climate change. However, many of these changes have positive combinatorial effects, so the best strategy is to pursue combinations of transportation GHG reduction strategies to meet reduction goals. Agencies need to broaden their agendas to incorporate such combination in their planning.

    Full Text Available In Ireland, timber and biomass haulage faces the challenge of transporting enough material within strict legal dimensions and gross vehicle weights restrictions for trucks and trailers. The objective of this study was to develop a method to control payload weight by knowing the moisture content of the wood. Weights, volumes, and moisture content were gathered from 100 truckloads of Sitka spruce pulpwood. Truck volume and weight utilization patterns were analyzed based on stacked volume, truck volume, and weights recorded from the weighbridge. Solid/bulk volume conversion factors for the truckloads were estimated indicating the truck’s solid volume capacity to be filled. Trucks were grouped into five conditions based on their configuration—volume capacity and legal maximum payload. A loaded volume fraction was estimated to assess the optimal volume capacity and stanchion height at which the trucks should be loaded. Results showed that 100% of the trucks presented volume underutilization, with a maximum of 27.5 m3 (only 39.85% volume capacity. In contrast, 67% of trucks were overweight while the remaining 33% were under the legal maximum weight. The average solid/bulk volume conversion factor was 0.66 ± 0.013 at 95% confidence level. Depending on the conditions, trucks can be filled to 100% of their volume capacity with wood at an MC from 29% to 55%. The minimum truck volume capacity utilization was 45%. This methodology can be used by truck hauliers, enabling them to determine in-forest the optimum volume and weight of wood to be transported by knowing the moisture content (MC, the wood specie, and using the height of the stanchions of the trailer as reference when loading the truck.

    Full Text Available The muffler is the main part of the Automobile Exhaust System, consisting of fibrous and porous materials to absorb noise and vibrations. The exhaust gas mass coming from the engine can produce resonance, which may be the source of fatigue failure in the exhaust pipe due to the presence of continuous resonance. The modes on the muffler should be located away from the engine’s operating frequencies in order to minimise the resonance. The objective of this paper is to determine the frequencies that appear at the modes, which have the more adverse effect during the operation of the automobile. An impact test has been conducted by applying the force using a hard head hammer, and data generated have been used for plotting a graph of the transfer functions using MATLAB. Six points have been selected, namely 1, 2, 3, 4, 7, and 11 on the muffler for the impact test. The collected data from theses six points have been analysed for the addition of damping. Results suggests that increasing the mass increases the damping and lowers the modes of the transfer function. Further research will identify higher strength materials that can withstand the higher gas temperatures as well as the corrosion and erosion by the gas emitted from the engine. muffler, noise, vibration,modal analysis,

    Full Text Available The advent of new technologies in last mile deliveries is about to cause a disruption in the traditional business model applied in urban cargo transportation, thus presenting innumerous research opportunities in this field of knowledge. In this context, identifying new operation models and vehicles that could be applied for last mile deliveries in urban areas becomes crucial. Therefore, this paper aims to identify, through a systematic literature review, the main types of vehicles addressed in the literature that could be used in the last mile of urban freight distribution in order to increase the sustainability of this type of operation. The results indicate a trend for the implementation of smaller and lighter vehicles for last mile deliveries in urban areas: 47% of the studies suggest, among other alternatives, the use of bicycles and tricycles; while 53% of the articles support the use of light commercial vehicles. Another trend observed in this type of distribution, indicated in 64% of the studies, is the shift from conventional (fossil fuels to alternative sources of energy (electricity.

In the present scenario, increasing demand and excessive use of automobiles have increased the level of carbon dioxide emission in the environment, providing a significant contribution to increase the global warming. This paper deals with the modeling of the effect of automobiles on global warming. For this, three nonlinearly interacting variables namely; density of human population, density of automobiles and the concentration of carbon dioxide have been taken into account. In the modeling process, it is assumed that the density of automobiles increases in proportion to human population following a logistic growth. The model is analyzed using stability theory of ordinary differential equations. Local and global stability conditions are established to study the feasibility of the model system. It is shown that with increase in human population, the demand for automobiles increases which has significant effect on global warming increase.

    The STEEP STREAMS (Solid Transport Evaluation and Efficiency in Prevention: Sustainable Techniques of Rational Engineering and Advanced MethodS) project consists of a collaboration among the Universities of Trento, Uppsala and Lisbon, who joined in a consortium within the ERANET Water JPI call WaterWorks2014. The aim of the project is to produce new rational criteria for the design of protection works against debris flows, a phenomenon consisting in hyper-concentrated flows of water and sediments, classified as catastrophic events typical of small mountainous basins (area risk of damage and even loss of human lives. These extreme events occur almost annually across Europe, though the formal return period in an exposed site is much larger. Recently, an increase in intensity and frequency of small-scale storm events, leading to extreme solid transport in steep channels, are recognized as one of the effects of climate change. In this context, one of the key challenges of this project is the use of comparatively coarse RCM projections to the small catchments examined in STEEP STREAMS. Given these changes, conventional protection works and their design criteria may not suffice to provide adequate levels of protection to human life and urban settlements. These structures create a storage area upstream the alluvial fans and the settlements, thereby reducing the need of channelization in areas often constrained by urban regulations. To optimize the lamination, and in particular to reduce the peak of solid mass flux, it is necessary that the deposition basin is controlled by a slit check dam, capable of inducing a controlled sedimentation of the solid mas flux. In order to achieve that, reliable design tools are needed. Driftwood represents another important factor increasing the risk, as clogging induced by the vegetal material represents a major problem for the operational reliability of slit check dams. Current procedures in compiling hazardous maps do not account for

    Full Text Available The article analyzes the way in which the modern car-advertisement defines the identity of women as potential purchasers – to whom it is designed to get through. The research includes language and iconic instruments by which this type of advertisement aims to create a feminized market of products formerly recognized as traditionally masculine. The identification of the addressee of each publicity material might be subsumed under a set of stereotypes, thus enabling advertisers to get across their message using the code of addressee’s own values. The present paper concentrates on the linguistic specifity of the ads for high-tech goods (automobiles targeting the feminine public and eventually points out their high degree of markedness according to the sex of addressees. Discourse analysis and a closer look at linguistic means appearing in French, Spanish and Polish automotive commercials both reveals a stereotyped woman’s image and shows how they happen to perpetutate it.

  6. PRODUCT EFFICIENCY IN THE SPANISH AUTOMOBILE MARKET

    Directory of Open Access Journals (Sweden)

    González, Eduardo

    2013-01-01

    Full Text Available This paper evaluates product efficiency in the Spanish automobile market. We use non parametric frontier techniques in order to estimate product efficiency scores for each model. These scores reflect the minimum price for which each car could be sold, given the bundle of tangible features it offers in comparison to the best-buy models. Unlike previous research, we use discounted prices which have been adjusted by car dealerships to meet sale targets. Therefore, we interpret the efficiency scores as indicators of the value of the intangible features of the brand. The results show that Audi, Volvo, Volkswagen and Mercedes offer the greatest intangible value, since they are heavily overpriced in terms of price/product ratios. Conversely, Seat, Kia, Renault and Dacia are the brands that can be taken as referent in terms of price/product ratios.

    The aim of the project on the title subject is to gain insight into possible developments of a future traffic and transportation system, into the role of electricity in such a system, and into possible strategies to stimulate desired developments. The project has been subdivided into five sub-projects for which separate reports were prepared: (1) Transport demand and transportation systems; (2) New drive concepts; (3) Strategies for innovation; (4) Transport of passengers and lifestyle; and (5) Transport and energy. The study is based on four scenarios: Unlimited Growth (high economic growth and little basis for sustainability), Slow Pace (low economic growth and little basis for sustainability), Sustainable Growth (high economic growth and much support for sustainable development), and Sustainable Balance (low economic growth and much support for sustainable development). For each scenario developments of transportation concepts, vehicle concepts and drive concepts are considered. The aim of the title subproject is to inventorize existing development trajectories in the field of traditional and alternative drive concepts for passenger and freight transport and to indicate new options. Several concepts are compared for their applicability and sustainability (efficiency improvement and emission reduction). Energy consumption, emissions and costs of selected drives is estimated for the years 1996, 2005, 2020, and 2050 for different vehicle types (automobiles, buses, vans, trucks, trains and inland shipping). 12 refs.

    2008-01-01

    Over the past 50 years, the National Aeronautics and Space Administration (NASA) has delivered space transportation solutions for America's complex missions, ranging from scientific payloads that expand knowledge, such as the Hubble Space Telescope, to astronauts and lunar rovers destined for voyages to the Moon. Currently, the venerable Space Shuttle, which has been in service since 1981, provides the United States' (U.S.) capability for both crew and heavy cargo to low-Earth orbit to' construct the International Space Station, before the Shuttle is retired in 2010. In the next decade, NASA will replace this system with a duo of launch vehicles: the Ares I Crew Launch Vehicle and the Ares V Cargo Launch Vehicle (Figure 1). The goals for this new system include increased safety and reliability coupled with lower operations costs that promote sustainable space exploration for decades to come. The Ares I will loft the Orion Crew Exploration Vehicle, while the heavy-lift Ares V will carry the Altair Lunar Lander and the equipment and supplies needed to construct a lunar outpost for a new generation of human and robotic space pioneers. This paper will provide details of the in-house systems engineering and vehicle integration work now being performed for the Ares I and planned for the Ares V. It will give an overview of the Ares I system-level test activities, such as the ground vibration testing that will be conducted in the Marshall Center's Dynamic Test Stand to verify the integrated vehicle stack's structural integrity and to validate computer modeling and simulation (Figure 2), as well as the main propulsion test article analysis to be conducted in the Static Test Stand. These activities also will help prove and refine mission concepts of operation, while supporting the spectrum of design and development work being performed by Marshall's Engineering Directorate, ranging from launch vehicles and lunar rovers to scientific spacecraft and associated experiments

    Edward Hanawalt

    2017-11-01

    Full Text Available Purpose: Evaluating country manufacturing location attractiveness on various performance measures deepens the analysis and provides a more informed basis for manufacturing site selection versus reliance on labor rates alone. A short list of countries can be used to drive regional considerations for site-specific selection within a country. Design/methodology/approach: The two-step multi attribute decision model contains an initial filter layer to require minimum values for low weighted attributes and provides a rank order utility score for twenty three countries studied. The model contains 11 key explanatory variables with Labor Rate, Material Cost, and Logistics making up the top 3 attributes and representing 54% percent of the model weights. Findings: We propose a multi attribute decision framework for strategically assessing the attractiveness of a country as a location for manufacturing automobiles. Research limitations/implications: Consideration of country level wage variation, specific tariffs, and other economic incentives provides a secondary analysis after the initial list of candidate countries is defined. Practical implications: The results of our modeling shows China, India, and Mexico are currently the top ranked countries for manufacturing attractiveness. These three markets hold the highest utility scores throughout sensitivity analysis on the labor rate attribute weight rating, highlighting the strength and potential of manufacturing in China, India, and Mexico. Originality/value: Combining MAUT with regression analysis to simplify model to core factors then using a “must have” layer to handle extreme impacts of low weight factors and allowing for ease of repeatability.

  8. Electricity as Transportation ``Fuel''

    Science.gov (United States)

    Tamor, Michael

    2013-04-01

    The personal automobile is a surprisingly efficient device, but its place in a sustainable transportation future hinges on its ability use a sustainable fuel. While electricity is widely expected to be such a ``fuel,'' the viability of electric vehicles rests on the validity of three assumptions. First, that the emissions from generation will be significantly lower than those from competing chemical fuels whether `renewable' or fossil. Second, that advances in battery technology will deliver adequate range and durability at an affordable cost. Third, that most customers will accept any functional limitations intrinsic to electrochemical energy storage. While the first two are subjects of active research and vigorous policy debate, the third is treated virtually as a given. Popular statements to the effect that ``because 70% of all daily travel is accomplished in less than 100 miles, mass deployment of 100 mile EVs will electrify 70% of all travel'' are based on collections of one-day travel reports such as the National Household Travel Survey, and so effectively ignore the complexities of individual needs. We have analyzed the day-to-day variations of individual vehicle usage in multiple regions and draw very different conclusions. Most significant is that limited EV range results in a level of inconvenience that is likely to be unacceptable to the vast majority of vehicle owners, and for those who would accept that inconvenience, battery costs must be absurdly low to achieve any economic payback. In contrast, the plug-in hybrid (PHEV) does not suffer range limitations and delivers economic payback for most users at realistic battery costs. More importantly, these findings appear to be universal in developed nations, with labor market population density being a powerful predictor of personal vehicle usage. This ``scalable city'' hypothesis may prove to a powerful predictor of the evolution of transportation in the large cities of the developing world.

  10. Reducing Weight for Transportation Applications: Technology Challenges and Opportunities

    Science.gov (United States)

    Taub, Alan I.

    Today's land, sea and air transportation industries — as a business necessity — are focused on technology solutions that will make vehicles more sustainable in terms of energy, the environment, safety and affordability. Reducing vehicle weight is a key enabler for meeting these challenges as well as increasing payload and improving performance. The potential weight reductions from substituting lightweight metals (advanced high-strength steels, aluminum, magnesium and titanium alloys) are well established. For magnesium castings, weight savings of 60% have been reported [1]. The value of weight reduction depends on the transportation sector and ranges from about 5/kg saved for automobiles to over 500/kg saved for aircraft [2]. The challenge is to optimize the material properties and develop robust, high volume, manufacturing technologies and the associated supply chain to fabricate components and subsystems at the appropriate cost for each application.

  11. Conceptual modelling of the interaction between transportation, land use and the environment as a tool for selecting sustainability indicators of urban mobility.

    Directory of Open Access Journals (Sweden)

    Giovanni Fusco

    2002-03-01

    Full Text Available There is an internationally shared agreement on the use of indicators for evaluating the sustainability of the observed patterns of urban development. The most commonly used framework to organise and select such indicators is the Pressures-State-Responses scheme. First proposed by the OECD to organise environmental indicators, its inadequacy is increasingly evident. The weaknesses of the conceptual frameworks currently used in urban sustainability analysis induced us to develop a more coherent theoretical framework in the form of a systemic scheme. The new scheme combines the causal approach of the Pressures-State-Responses model and the focus on urban sustainability issues of the extended urban metabolism model by Newman and Kenworthy. In this paper, the new scheme was used to derive a systemic framework for the assessment of the sustainability of urban mobility. First, we adapted the general scheme to the analysis of urban mobility. Successively, using the cognitive mapping software Decision Explorer, we further developed this scheme to obtain a more disaggregated conceptual model. A selection table could be derived for every element of the model to guide the selection of pertinent indicators based on the systemic links of the element. We could thus define a set of some sixty system indicators to be used in the assessment of the sustainability of urban mobility. The selected set of indicators reflects the causal links between phenomena and can monitor the attainment of sustainability objectives for the urban mobility system. All indicators allow geographical comparison and integrate the role played by different urban actors and modes of transportation. This work has been carried out within the first year of a joint PhD research program at the University of Nice-Sophia Antipolis and at the Polytechnic of Milan.

    2017-01-01

    Full Text Available The need for liquid and gaseous fuel for transportation application is growing very fast. This high consumption trend causes swift exhaustion of fossil fuel reserve as well as severe environment pollution. Biogas can be converted into various renewable automobile fuels such as bio-CNG, syngas, gasoline, and liquefied biogas. However, bio-CNG, a compressed biogas with high methane content, can be a promising candidate as vehicle fuel in replacement of conventional fuel to resolve this problem. This paper presents an overview of available liquid and gaseous fuel commonly used as transportation fuel in Bangladesh. The paper also illustrates the potential of bio-CNG conversion from biogas in Bangladesh. It is estimated that, in the fiscal year 2012-2013, the country had about 7.6775 billion m3 biogas potential equivalent to 5.088 billion m3 of bio-CNG. Bio-CNG is competitive to the conventional automobile fuels in terms of its properties, economy, and emission.

    The cost of transportation for monthly clinic visits has been identified as a potential barrier to antiretroviral (ARV) adherence in sub-Saharan Africa and elsewhere, although there is limited data on this issue. We conducted open-ended interviews with 41 individuals living with HIV/AIDS and attending a clinic in Mbarara, Uganda, to understand structural barriers to ARV adherence and clinical care. Almost all respondents cited the need to locate funds for the monthly clinic visit as a constant source of stress and anxiety, and lack of money for transportation was a key factor in cases of missed doses and missed medical appointments. Participants struggled with competing demands between transport costs and other necessities such as food, housing and school fees. Our findings suggest that transportation costs can compromise both ARV adherence and access to care. Interventions that address this barrier will be important to ensure the success of ARV programs in sub-Saharan Africa.

    Multiple injuries are frequently observed over the whole body of traffic victims in medico-legal autopsy cases. The assessment of a traffic casualty must include not only the victim but also the vehicle and the circumstances of the accident. Only consideration of all available data permits a better assessment of the mechanism of the crash and causation of injuries. J. M. Thevenet drove the first car carried from France to Japan on February 6, 1898. On October 28th, 1905, the first death by a road traffic accident occurred in Osaka. We performed a retrospective analysis of 279 traffic fatalities examined by medico-legal autopsy in Niigata that occurred over a twenty-two-year period from 1980 to 2001. All persons who had an ICD-10 code were grouped by 153 pedestrians, 43 pedal cyclists, 20 motorcycle riders, 45 car occupants, 11 occupants of pick-up trucks or vans, 4 occupants of heavy transport vehicles and 3 others. The average of ISS (injury scale score) is 40.7 in pedestrians, 26.7 in pedal cyclists, 32.4 in motorcycle riders, 25.1 in car occupants, 16.5 in occupants of pick-up trucks or vans, 24.0 in heavy transport vehicles and 69.0 in others. Rib fractures were observed in 170 cases (60.9%) and the frequency of other injuries was shown in Table 2. Criminal Punishment for drivers involved in 261 traffic accidents amounted to 35 sentences of imprisonment (13.4%), 46 suspension of execution of sentence (17.6%) and 60 sentence of fine (23.0%). Forty prone pedestrians run over by cars showed high ethanol levels in their blood. It was necessary to identify the driver of a vehicle in twelve car accidents and simulation with a computer is very useful. The average of ISS was 34.0 in ten drivers and 22.0 in fourteen fellow passengers. Four sudden natural deaths of drivers at the wheel, eight cases of death immediately after and from one day to five months after road traffic accidents, nine suicides and one intentional accident are excluded from traffic death.

    Full Text Available Although China has promoted the construction of Chinese Sustainable Ground Transportation (CSGT to guide sustainable development, it may create substantial challenges, such as rapid urban growth and land limitations. This research assessed the effects of the Hangzhou Bay Bridge on impervious surface growth in Cixi County, Ningbo, Zhejiang Province, China. Changes in impervious surfaces were mapped based on Landsat images from 1995, 2002, and 2009 using a combination of multiple endmember spectral mixture analysis (MESMA and landscape metrics. The results indicated that the area and density of impervious surfaces increased significantly during construction of the Hangzhou Bay Bridge (2002–2009. Additionally, the bridge and connected road networks promoted urban development along major roads, resulting in compact growth patterns of impervious surfaces in urbanized regions. Moreover, the Hangzhou Bay Bridge promoted the expansion and densification of impervious surfaces in Hangzhou Bay District, which surrounds the bridge. The bridge also accelerated socioeconomic growth in the area, promoting rapid urban growth in Cixi County between 2002 and 2009. Overall, the Hangzhou Bay Bridge is an important driver of urban growth in Cixi County, and policy suggestions for sustainable urban growth should be adopted in the future.

    Full Text Available With the increase of human population there has been an evident increase in per capita automobile use and ownership, significantly to a point that almost every urban university campus faces serious challenges from the heavy traffic movement as well as the associated parking shortages. Multiple factors, including lack of land for new parking lots, high cost of building parking structures and the desire to preserve the air quality and campus green spaces are leading many educational institutions towards a new vision based upon expanded transit access, better bicycle and pedestrian facilities and financial incentives for students and staff to drive less. (Toor and Havlick, 2004 This is in stark contrast to the traditional approach to campus transportation planning of the University of Malaya (UM, Kuala Lumpur, Malaysia that allows students, staff and visitors to drive in the campus. The objective of this study is to investigate the related issues and environmental impact of allowing automobile driving in the campus. Studies will also be done to analyse the relationship between university campus planning and traffic condition. Air quality and noise pollution data of 3 selected sites in the campus will be recorded. Subsequently, the air pollutant index and noise pollution level will be identified and data analyses will be done on the data samples. Simultaneously, a survey questionnaire will be conducted to gauge the student’s attitude and degree of awareness with air and noise pollution in the campus. This pilot study reveals that the increasing use of automobiles within the campus has a negative impact on local environment and the quality of life in campus

    The usage of ethanol in buses is a reality in cities from Sweden, such as Stockholm. The technology of diesel bus adapted to operate with ethanol has been used in that country since 1985, with great success, mainly in the environmental point of view. With the intent of encouraging ethanol usage in urban public transportation aiming, among other goals, at the reduction of atmospheric pollution in the big urban centers, the BEST Project - BioEthanol for Sustainable Transport was created. Besides Sao Paulo (pioneer in the Americas), this project, encouraged by the European Union, counts with eight other cities located in Europe and Asia. In Brazil, the project was developed and coordinated by CENBIO - Brazilian Reference Center on Biomass, from the Electrotechnics and Energy Institute of USP. With the partnership of other institutions, the project is developed since 2007 and currently counts on two diesel buses adapted to operate with ethanol. The buses circulate in operatives from EMTU - Sao Paulo Metropolitan Company for Urban Transports, in the Jabaquara - Sao Mateus line, and in operative from SPTrans - Sao Paulo Transportations, in the Lapa - Vila Mariana corridor. This paper has as its purpose to present the BEST Project in Brazil, its partners and, mainly, the results from the demonstration tests performed in field, as well as the proposals of public policies that were elaborated and are being implemented. It is worth remembering that the technology of the buses pays attention to the EURO 5 strict emission Standards, a norm that was recently invigorated in Europe. (author)

    The urban transport problem is fundamentally similar in all large cities. The basic causes are the same and so are many of the consequences, although there are some differences in degree between cities in developed and developing economies. Transport systems in large cities of the developing economies as compared to the developed economies are characterized by: (a) much lower level of motorization of transport and travel requirement, (b) more rapid rates of economic growth, population growth, and the growth in number of motor vehicles, (c) higher population densities, (d) much lower per capita energy consumption and emissions of carbon dioxide, (e) reduced access to capital and to advanced environmental technologies. Despite greater level of vehicle ownership, higher rate of trip generation and increased use of energy on a per capita basis in cities of developed countries, it is the large cities in the developing countries that, in general suffer most from growing traffic congestion, road accidents, energy use and emissions, overcrowding of public transport, and poor conditions for pedestrians and cyclists.

    IAEA education and training activities follow the resolutions of its General Conferences and reflects the latest IAEA standards and guidance. IAEA prepared a 'Strategic Approach to Education and Training in Radiation and Waste Safety' (Strategy on Education and Training) aiming at establishing, by 2010, sustainable education and training programmes in Member States, which was endorsed by the GC(45)/R.E.S./10 C in 2001. In implementing the strategy, IAEA is organizing training events in the regional level and assisting the Member States at the national level by providing them with exemplary quality of training material developed at the Agency. This work will continue ensuring its completeness in all areas of radiation protection. An Inter Centre Network between the Agency and regional, collaborating national training centres is established to facilitate information exchange, improve communication and dissemination of training material. There is a challenge to enhance the technical capability of the Member States to reach sustainability. This is intended through organizing number of Train the Trainers workshops to develop a pool of qualified trainers. The syllabus for training of Radiation Protection Officers is developed and a protocol document for educational and training appraisal (E.d.u.T.A.) is developed. The new developments include web enabling the approved training packages and establish E.learning and carrying out E.d.u.T.A. missions, aimed at identifying training needs in Member States and support them to build their own training strategy. These activities are aimed at assisting Member States attain self sustainability. (authors)

    2017-06-01

    Full Text Available The automobile industry is one of the most rapidly growing industries, a significant employer and investor in research and development, and also one of the most important sectors of the EU economy. Nevertheless, even this sector has gone through a series of structural changes and territorial transfers, recently. Exactly for this reason, it seems crucial to examine the competitiveness of the automobile industry on the national level, analyze the long-term trends throughout the whole EU, and put them in a global context. The article uses standard methods of statistical analysis of indices of revealed symmetrical comparative advantage to detect the trends characterizing the shape and long-term development of the automobile industry in Europe. The authors point out the substantial shift s in production and exports from traditional Western European car makers in favor of the new EU member states, but also from the USA and Canada in favor of new, fast-growing developing countries in the South and Southeast Asia and in Latin America. A brief outline of the European Commission’s response to these changes in the European automobile industry in the form of an Action Plan CARS 2020 can be found in the final part of the article.

    Current conditions of the cognitive economy formation demand to take into account the leading role of information, knowledge and human capital in the development of the transport industry management system. The article substantiates the conceptual approach to the self-organization of a management system on the basis of innovative changes. Human capital is the key aspect of self-organization, so the directions of improving the workforce quality are justified. Basing on the information-innovative genesis of the process of self-organization, the authors justified the necessity of preventing asymmetric information. For this pupose the actions against the resistance to innovations were proposed. The implementation of certain measures contributes to the effective development of the transport management system.

    2000-07-01

    This book is a guide for people wishing to liberate themselves from their addiction to cars and the automobile culture. It is a repository of examples and actions that individuals and communities can take to reduce dependence on the automobile. The range of possibilities run from using cars less to not owning one at all. The book provides a humorous yet clear-headed approach to a greener world and maps out the road to how people can live happily ever after by breaking free of 'auto-cracy', without insisting on people in car-dependent countries quit their automotive addiction instantly. Nevertheless, it clearly articulates the connection between automobiles, their arteries (i.e. highways) and effluents (i.e. greenhouse gases and particulate emissions), and the increasing number and severity of natural disasters between the urban renewal and freeway construction that, in the author's view, helped ignite the riots in Watts, Newark and Detroit. The disastrous societal and geophysical effects of the automobile are demonstrated in great abundance, and the mountain of evidence of the systematic abuse of the planet that the book provides is a stunning refutation of the notion that technology is neutral. The automobile is accused of being not only the linchpin of Western and primarily American industrialism and resource extraction, it is also accused of being the chief suspect in a century-long theft of time, conviviality and beauty. How to bring about a change in people's love affair with their cars is difficult to comprehend but this author has a multitude of useful suggestions which seem to suggest that it is possible. There is a list of 104 'selected references' and an extensive list of 'other resources'.

    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

    1989-01-01

    Studies in other countries have demonstrated that properly worn seatbelts dramatically reduce the likelihood and seriousness of injuries in motor vehicle accidents. However, in the western region of Mexico, they are very rarely worn, due to the erroneous belief that its use does not protect, and may even harm its wearer. In order to ascertain its benefit or lack of it, we undertook a survey, comparing the degree of severity of lesions sustained, as well as the mortality, between a group of 15 patients who wore seatbelts and another of 35 patients who did not wear them; all patients were treated at the Emergency Room of the Hospital de Especialidades del Centro Médico de Occidente, after suffering car accidents. Among the first group, only one patient required hospitalization and there were no deaths. In the second group, all 35 patients had to be hospitalized, eight had sequelae and nine died. We conclude that seatbelts effectively protect the wearer against death and limit the severity of the injuries suffered during car accidents. We propose that educational campaigns to convince the public as to the benefits of its use should be carried out, and after a reasonable interval its use should be mandated by law.

    Railways currently play an important role in sustainable transportation systems, owing to their substantial carrying capacity, environmental friendliness and land-saving advantages. Although total pollutant emissions from railway systems are far less than that of automobile vehicles, the pollution from railway operations should not be underestimated. To date, both scientific and practical papers dealing with stormwater management for rail tracks have solely focused on its drainage function. Unlike roadway transport, the potential of stormwater pollution from railway operations is currently mishandled. There have been very few studies into the impact of its operations on water quality. Hence, upon the realisation on the significance of nonpoint source pollution, stormwater management priorities should have been re-evaluated. This paper provides an examination of past and current practices of stormwater management in the railway industry, potential sources of stormwater pollution, obstacles faced in stormwater management and concludes with strategies for future management directions.

    Plants experience a highly variable light environment over the course of the day. To reveal the molecular mechanisms of their photosynthetic response to fluctuating light, we examined the role of two cyclic electron flows around photosystem I (CEF-PSI)--one depending on PROTON GRADIENT REGULATION 5 (PGR5) and one on NADH dehydrogenase-like complex (NDH)--in photosynthetic regulation under fluctuating light in rice (Oryza sativa L.). The impairment of PGR5-dependent CEF-PSI suppressed the photosynthetic response immediately after sudden irradiation, whereas the impairment of NDH-dependent CEF-PSI did not. However, the impairment of either PGR5-dependent or NDH-dependent CEF-PSl reduced the photosynthetic rate under fluctuating light, leading to photoinhibition at PSI and consequently a reduction in plant biomass. The results highlight that (1) PGR5-dependent CEF-PSI is a key regulator of rapid photosynthetic responses to high light intensity under fluctuating light conditions after constant high light; and (2) both PGR5-dependent and NDH-dependent CEF-PSI have physiological roles in sustaining photosynthesis and plant growth in rice under repeated light fluctuations. The highly responsive regulatory system managed by CEF-PSI appears able to optimize photosynthesis and plant growth under naturally fluctuating light conditions.

    Air contains a lot of pollutants and most of these pollutants are toxic. Carbon monoxide (CO) is one of the five primary pollutants, which together contributes more than 90% of global atmospheric pollution. Therefore, CO has been chosen for this analytical study. The main source of CO is the exhaust from automobiles only. In the present situation, the usage of motor vehicles rapidly expanded. The number of vehicles cannot be reduced but their emission (which is a cause for pollution) can be effectively controlled. In this direction, a model has been developed in this study to sense the level of carbon monoxide emitted from the automobiles. When the exhaust reaches a harmful level it sends the data about the vehicle number and the concentration of CO to the emission-testing centre (PC). As a result the government can take necessary action to seize the particular vehicle emitting more carbon monoxide than the permitted level.

    Based on the connection mechanism of nodes which automatically select upstream and downstream agents, a simulation model for dynamic evolutionary process of consumer-driven automobile supply chain is established by integrating ABM and discrete modeling in the GIS-based map. Firstly, the rationality is proved by analyzing the consistency of sales and changes in various agent parameters between the simulation model and a real automobile supply chain. Second, through complex network theory, hierarchical structures of the model and relationships of networks at different levels are analyzed to calculate various characteristic parameters such as mean distance, mean clustering coefficients, and degree distributions. By doing so, it verifies that the model is a typical scale-free network and small-world network. Finally, the motion law of this model is analyzed from the perspective of complex self-adaptive systems. The chaotic state of the simulation system is verified, which suggests that this system has typical nonlinear characteristics. This model not only macroscopically illustrates the dynamic evolution of complex networks of automobile supply chain but also microcosmically reflects the business process of each agent. Moreover, the model construction and simulation of the system by means of combining CAS theory and complex networks supplies a novel method for supply chain analysis, as well as theory bases and experience for supply chain analysis of auto companies.

  19. Individual sustainable mobility - priorities for policy reform and an agenda for action

    Energy Technology Data Exchange (ETDEWEB)

    Gwilliam, K.M. [The World Bank, Washington, DC (United States)

    1996-11-01

    This paper argues that the problem of individual sustainable mobility is predominantly an urban problem. In that context, `individual` cannot be narrowly interpreted as private automobile, and `sustainability` cannot be narrowly interpreted as only environmental; a sound economics basis is required for the achievement of environmental and social objectives, and trade offs between economic, social and environmental objectives must be recognized and confronted. Urban form is important, as a means of influencing both total demand and modal split. But it has severe limitations, particularly in developing countries and must be supported by appropriate institutional and pricing structures. Technology can attenuate but not overcome the problems of private mobility, and the role of simple technologies needs to be given more careful attention. Public transport retains a critical role but must also be treated in a practical, economic manner. Competition, to improve efficiency, can be reconciled with social and environmental objectives through appropriate design of franchising and regulatory regimes. All of these instruments are only likely to be effectively deployed in an appropriate institutional context, involving proper coordination of land use and transport planning, of transport functions and nodes, and of local jurisdictions.

    They are a familiar sight on roads in Sweden and Finland. The Dutch are testing them, and on just a few routes in Germany they are also being tested. We are talking about so-called megatrucks. With a maximum length of 25.25 metres and a permissible maximum loaded weight of 60 tonnes these are noticeably larger than standard 40-tonners, whose maximum length is restricted to 18.75 metres. Hauliers are presently testing operation of longer and heavier truck-trailer combinations in Germany. Some Laender - for example, Baden-Wuerttemberg, Bremen, Lower Saxony and Saxony- Anhalt - have issued exemptions for the trial operation of megatrucks on clearly defined routes. In Bremen, special coffee transporters of the 60-tonne class have been on the road since mid 2005 between the inland port and a major coffee roaster. Permits in Lower Saxony are restricted to three routes and expire in the summer of 2007. During this time, experience should be gained with this new and - on German roads - unusual type of truck. Early results are already available. In the meantime, logistics companies are thinking ahead: they want to start a field trial in the medium term throughout the country with a large fleet of megatrucks. What are the implications for sustainable transport development of the introduction of longer and heavier vehicles (LHVs), which are up to 6.5 metres longer than standard heavy-duty vehicles (HDVs)? The Federal Environment Agency (UBA) addresses below a number of important questions concerning megatrucks from the environmental protection point of view: What effect do they have on fuel consumption as well as on emissions of air pollutants and traffic noise? What effects does their introduction have on other carriers? Do megatrucks reduce the demand for roadspace and the risk of traffic congestion? Is road infrastructure suitable for these longer and heavier vehicles? Answers to these questions are then summarized in the conclusion. (orig.)

    2007-01-01

    The National Park Service (NPS) is increasingly focusing on alternative transportation systems in national parks to address environmental and social problems arising from a historical reliance on personal automobiles as the primary means of visitor access. Despite the potential advantages, alternative transportation may require a reorientation in the way that Americans have experienced national parks since the advent of auto-tourism in the early twentieth century. Little research exists, however, on visitor perspectives towards alternative transportation or the rationale underlying their perspectives. It remains unclear how transportation systems affect visitors’ experiences of the park landscape or the factors influencing their travel behavior in the parks. This report presents an interpretive study of visitor perspectives toward transportation management in the Yosemite Valley area of Yosemite National Park, California. Qualitative analysis of 160 semi-structured interviews identified individual psychological factors as well as situational influences that affect visitors’ behavior and perspectives. Individual psychological factors include perceived freedom, environmental values and beliefs, prior experience with Yosemite National Park and other national parks, prior experience with alternative transportation in national parks, and sensitivity to subjective perceptions of crowding. Situational factors included convenience, access, and flexibility of travel modes, as well as type of visit, type of group, and park use level. Interpretive communication designed to encourage voluntary visitor use of alternative transportation should focus on these psychological and situational factors. Although challenges remain, the results of this study suggest approaches for shaping the way Americans visit and experience their national parks to encourage environmental sustainability.

  8. Providing Consumers with Web-Based Information on the Environmental Effects of Automobiles

    Energy Technology Data Exchange (ETDEWEB)

    The Department of Energy (DOE) and the Environmental Protection Agency (EPA) provide consumers with web-based information on the environmental effects of automobiles so that individuals can make informed choices about the vehicles they use or may purchase. DOE and EPA maintain a web site (www.fueleconomy.gov) that provides users with information about fuel economy [as well as greenhouse gas (GHG) emissions and air pollution emissions] for the cars and trucks they use or may consider purchasing. EPA also maintains a separate web site (www.epa.gov/greenvehicles) that offers similar information, with the focus on air pollution emissions rather than fuel economy. The American Council for an Energy-Efficient Economy (ACEEE) (www.greenercars.com) and the California Air Resources Board (CARB) (www.arb.ca.gov/msprog/ccbg/ccbg.htm) also maintain web sites that provide consumers with information on the environmental effects of automobiles. Through the National Transportation Research Center (NTRC) at Oak Ridge National Laboratory, DOE has supported some initial qualitative research with people who are interested in purchasing a new or used vehicle and whose actions identify them as at least somewhat concerned about the environment. The purpose of this research was to explore and understand how these people respond to the different ratings and measurements of environmental effects provided by the four web sites. The goal of the research is to optimize the communication of information provided on the DOE/EPA web site (www.fueleconomy.gov). Working with a private marketing research firm (The Looking Glass Group of Knoxville, Tennessee), NTRC staff initiated this research by meeting with two focus groups in Knoxville on February 27, 2001. To obtain information for comparison, staff from the NTRC and the Looking Glass Group also met with two focus groups in Los Angeles, California, on August 13, 2001.

    2017-07-01

    To study the ignition characteristics of semiconductor bridges (SCB) for automobile airbag igniters, a model was proposed to compute the electrical characteristics of SCB based on the structural characteristics, resistance properties, and the working process of the bridge. Numerical simulation was conducted to analyze the voltage and current trends at two ends of bridges with various geometric dimensions and those with identical geometric dimensions and oxide layers of different thicknesses. Voltage-current curves for bridges of three different dimensions were obtained through numerical simulation. Bridges of larger geometric dimensions were found to require higher voltage to reach the melting point, which means higher energy input is required.

    2008-12-01

    Full Text Available This review discusses key technologies of intelligent tires focusing on sensors and wireless data transmission. Intelligent automobile tires, which monitor their pressure, deformation, wheel loading, friction, or tread wear, are expected to improve the reliability of tires and tire control systems. However, in installing sensors in a tire, many problems have to be considered, such as compatibility of the sensors with tire rubber, wireless transmission, and battery installments. As regards sensing, this review discusses indirect methods using existing sensors, such as that for wheel speed, and direct methods, such as surface acoustic wave sensors and piezoelectric sensors. For wireless transmission, passive wireless methods and energy harvesting are also discussed.

  15. Is Automobile Dependence in Emerging Cities an Irresistible Force? Perspectives from São Paulo, Taipei, Prague, Mumbai, Shanghai, Beijing, and Guangzhou

    Directory of Open Access Journals (Sweden)

    Jeffrey R. Kenworthy

    2017-10-01

    Full Text Available This paper analyses seven metropolitan regions that are all experiencing rapid motorisation and are perhaps appearing to capitulate to the automobile. Through 20 years of changes, evidenced in systematic data from the mid-1990s, a different perspective is found. None of the urban regions appear near to or even capable of becoming automobile cities. Physical limits are already being reached that make higher levels of private motorised mobility very problematic if transport systems are to remain functional and the cities livable. These limits appear already to be reversing the decline in non-motorised modes and creating an upturn in transit systems, especially urban rail. That these cities have been able to either hold their own, or somewhat increase their share of total motorised mobility by transit over a 20-year period, is some indication that they are ‘hitting mobility walls’ much sooner in the motorisation path than cities in North America and Australia, which grew up with and were designed around the spatial needs of cars. Like many cities in the developed world that have shown a decoupling of car use and total passenger mobility from GDP growth from 1995 to 2005, there is now evidence that this is happening in less wealthy cities. This is important because it assists global and local goals for reduced CO2 from passenger transport, while allowing for economic progress. Such evidence suggests that automobile dependence is not an irresistible force in emerging economies.

  16. Towards sustainable development

    Science.gov (United States)

    Munn, R. E.

    Sustainable development is a difficult phrase to define, particularly in the context of human ecosystems. Questions have to be asked, such as "Sustainable for whom?" "Sustainable for what purposes?" "Sustainable at the subsistence or at the luxury level?" and "Sustainable under what conditions?" In this paper, development is taken to mean improving the quality of life. (If development were to mean growth, then it could not be sustained over the long term.) Studies of development must, of course, consider economic factors, particularly in the case of societies who suffer from the pollution of poverty. However, cultural and environmental factors are equally important. In fact, development is not sustainable over the long term if it is not ecologically sustainable. The terms maximum sustainable yield of a renewable resource, carrying capacity of a region and assimilative capacity of a watershed or airshed are discussed. Approaches using these resource management tools are recommended when external conditions are not changing very much. The problem today is that unprecedented rates of change are expected in the next century, not only of environmental conditions such as climate but also of socioeconomic conditions such as renewable resource consumption and populations (of both people and of automobiles)! In rapidly changing situations, policies must be adopted that strengthen resilence and ecosystem integrity; that is, society must increase its ability to adapt. Maintaining the status quo is a long-term prescription for disaster. The problem is of course that little is known about how to design strategies that will increase resilience and ecosystem integrity, and this area of research needs to be strengthened. Some suggestions on appropriate indicators of ecosystem integrity are given in the paper but these need considerable refinement. One of the main problems with long-term environmental policy formulation is the uncertainty to be expected, including the possibility

  17. Development of automobile brake lining using pulverized cow hooves

    2016-06-01

    Full Text Available Asbestos has been used for so long as automobile brake lining material because of its good physical and chemical properties. However, due to the health hazard associated with its handling, it has lost favour and several alternative materials are being increasingly used. Asbestos-free brake lining was developed in this work using pulverized cow hooves along with epoxy resin, barium sulphate, graphite and aluminium oxide. This was with a view to exploiting the characteristics of cow hooves, which are largely discarded as waste materials to replace asbestos which has been found to be carcinogenic. Samples of brake linings were produced using compressive moulding in which the physical and mechanical properties of the samples were studied. The results obtained showed that proper bonding was achieved as the percentage by weight of epoxy resin increased and percentage by weight of pulverized cow hooves decreased. The hardness, compressive strength, coefficient of friction, water and oil absorption, relative density and wear rate of the brake linings were determined and compared with existing brake lining properties. The result indicates that pulverized cow hooves can be used as brake lining material for automobiles.

    2011-01-15

    The aim of this work was developing a hydrometallurgical process to recover metals from automobile shredded residue (or car fluff). Automobile shredded residue (ASR) was characterised by particle size distribution, total metal content and metal speciation in order to guide the choice of target metals and the operating conditions of leaching. Characterisation results showed that Fe is the most abundant metal in the waste, while Zn was the second abundant metal in the fraction with diameter lower than 500 μm. Sequential extractions denoted that Zn was easily extractable by weak acid attack, while Fe and Al required a strong acid attack to be removed. In order to recover zinc from acid, sulphuric acid and sodium hydroxide at different concentrations. Sulphuric acid determined the highest zinc extraction yield, while acetic acid determined the highest zinc extractive selectivity. Sodium hydroxide promoted an intermediate situation between sulphuric and acetic acid. Zn recovery by electro winning using acetic leach liquor determined 95% of Zn electro deposition yield in 1h, while using sulphuric leach liquor 40% yield in 1h and 50% yield in 2h were obtained. Simulation results showed that the sulphuric leaching process was more attractive than acetic leaching process. Copyright © 2010 Elsevier B.V. All rights reserved.

    Full Text Available The significance of the issue of an effective mode of passenger transport is currently increasing. On the one hand, there is the increasing economic demand of public passenger transport, on the other hand, there is the growing traffic share of individual automobile transport. The objective of the paper is to analyze public passenger transport without mutual integration of individual transport systems resulting in the fact that it is not sufficiently able to compete with individual automobile transport. It is proposed the integration of different modes of public passenger transport as a way to increase the competitiveness of public passenger transport. Aim of this paper is to analyze the individual elements of integration systems and describe why integration of public passenger transport systems is needed.

    The first symposium on 'Aluminium and the Automobile' took place in March 1976. The lectures of the latest symposium report on the time in between; with special regard to the extent and intensity with wich aluminium - whose advantages and desadvantages are known - was a subject of research and development work done by car producers and parts- and accessory producing industry. Producers of engine blocks, wheels brakes, sunroofs, window-glass mechanisms, heat exchangers, air-filters, drive shafts - just to mention a few described their success but also gave and account of so far unsolved problems. Aluminum and car producers from abroad gave valuable contributions as well. Good news is the technical progress which was clearly reflected in all the lectures. The automobile of the future needs to be further developed in order te fulfill the requirements of lower weight and energy saving cost reduction is equally important for the German and European car industry due to the increasingly hard competitive struggle. Contrary to previous predictions a sufficient supply of alluminium with be available in the years to come.

    2010-09-01

    Full Text Available In four ways, massively multiplayer online role-playing games may serve as tools for advancing sustainability goals, and as laboratories for developing alternatives to current social arrangements that have implications for the natural environment. First, by moving conspicuous consumption and other usually costly status competitions into virtual environments, these virtual worlds might reduce the need for physical resources. Second, they provide training that could prepare individuals to be teleworkers, and develop or demonstrate methods for using information technology to replace much transportation technology, notably in commuting. Third, virtual worlds and online games build international cooperation, even blending national cultures, thereby inching us toward not only the world consciousness needed for international agreements about the environment, but also toward non-spatial government that cuts across archaic nationalisms. Finally, realizing the potential social benefits of this new technology may urge us to reconsider a number of traditional societal institutions.

    To study the main risk factors of low back pain of workers ina foundry factory of the automobile company using cross sectional epidemiological investigation, and to provide scientific base for preventing the disorder. The low back pain and work loads of 1340 workers in a foundry factory of the automobile company were investigated using questionnaire, and logistic regression analysis was used to analyze the risk factors. The one-year morbidity of low back pain in workers was 58.9% the morbidities of low back pain in workers engaged in foundry, transportation and modeling were 64.6%, 64.6% and 62.5%, respectively. The lifting with squat postures, bending trunk heavily, bending trunk with twisting and moving the heavy objects were found to be the most dominant risk factors for low-back pain, the OR values were 2.085, 1.961, 1.967 and 1.956, respectively. The distributions of risk factors were different among the different jobs. The logistic regression analysis showed that moving the heavy objects, lifting with squat postures, bending trunk heavily, bending trunk with twisting existed simultaneously, also the work years and gender were the risk factors. The manual moving heavy objects, awkward working posture or both were the most important risk factors for low-back pain. The intervene ergonomic study should be performed in future to reduce the morbidity of low-back pain.

    2011-02-01

    Full Text Available Welding is one of the key components of numerous manufacturing industries, which has potential physical and chemical health hazards. Many components of welding fumes can potentially affect the lung function. This study investigates the effects of welding fumes on lung function and respiratory symptoms among welders of an automobile manufacturing plant in Iran. This historical cohort study assesses 43 male welders and 129 office workers by a questionnaire to record demographic data, smoking habits, work history and respiratory symptoms as well as lung function status by spirometry. The average pulmonary function values of welders were lower relative to controls with dose-effect relationship between work duration and pulmonary function impairment. The prevalence of chronic bronchitis was higher in welders than controls. Our findings suggest that welders are at risk for pulmonary disease.

    2013-12-01

    Engineering plastics are used in instrument panels, interior trims, and other vehicle applications, and the thermo-mechanical behaviors of plastic materials are strongly influenced by many environmental factors such as temperature, sunlight, and rain. As the material properties change, the mechanical parts create unexpected noise. In this study, the dynamic mechanical property changes of plastics used in automobiles are measured to investigate the effect of temperature. Visco-elastic properties such as the glass transition temperature and storage modulus and loss factors under temperature and frequency sweeps were measured. The data results were compared with the original ones before aging to analyze the behavioral changes. It was found that as the temperature increased, the storage modulus decreased and the loss factor increased slightly.

    2017-07-01

    The comparative contribution to human noise exposure from the vehicular radio is unknown, as are the radio volume preferences of different generations when driving an automobile. A single vehicle was used to measure radio listening level in decibels of three generations (age 16-17 years, age 32-50 years, and age 51-73 years) in various conditions, ranging from engine off with windows closed to 60 miles per hour (mph) with windows open. No differences in radio loudness based on the sex of the driver were found. Statistically significant differences were identified in preferred signal to noise ratio among multiple vehicular paradigms, with the youngest generation preferring the largest signal to noise ratio in conditions with low background noise. The youngest generation favored the largest signal to noise ratio (radio level above background noise), a preference which waned with increasing background noise. Copyright © 2017 Elsevier B.V.

    DOE-EE Bioenergy Technologies Office has set forth several goals to increase the use of bioenergy and bioproducts derived from renewable resources. One of these goals is to facilitate the implementation of the biorefinery. The biorefinery will include the production of liquid fuels, power and, in some cases, products. The integrated biorefinery should stand-alone from an economic perspective with fuels and power driving the economy of scale while the economics/profitability of the facility will be dependent on existing market conditions. UOP LLC proposed to demonstrate a fast pyrolysis based integrated biorefinery. Pacific Northwest National Laboratory (PNNL) has expertise in an important technology area of interest to UOP for use in their pyrolysis-based biorefinery. This CRADA project provides the supporting technology development and demonstration to allow incorporation of this technology into the biorefinery. PNNL developed catalytic hydrothermal gasification (CHG) for use with aqueous streams within the pyrolysis biorefinery. These aqueous streams included the aqueous phase separated from the fast pyrolysis bio-oil and the aqueous byproduct streams formed in the hydroprocessing of the bio-oil to finished products. The purpose of this project was to demonstrate a technically and economically viable technology for converting renewable biomass feedstocks to sustainable and fungible transportation fuels. To demonstrate the technology, UOP constructed and operated a pilot-scale biorefinery that processed one dry ton per day of biomass using fast pyrolysis. Specific objectives of the project were to: The anticipated outcomes of the project were a validated process technology, a range of validated feedstocks, product property and Life Cycle data, and technical and operating data upon which to base the design of a full-scale biorefinery. The anticipated long-term outcomes from successful commercialization of the technology were: (1) the replacement of a significant

    2005-11-01

    The automobile manufacturing industry plays a very important role in a country's economy. The importance of automobile manufacturing industry lies in its sheer size and complexity in terms of the direct and indirect influence it commands across many other industries. While millions of people are employed in the automobile manufacturing industry, it is estimated that more than two and half times that number are employed in the auxiliary companies that supply parts to the automobile manufacturing companies. The auxiliary companies represent a group of businesses of various sizes, types, and geographical locations, producing a vast variety of products ranging from the very simple to the extremely intricate. In this study, the current environmental practices of management in the core Spanish auxiliary companies that do business with the automobile manufacturing industry (and thus form a large part of the automobile manufacturing industry's supply chain) are investigated. We show that while automobile manufacturing companies are under scrutiny to become more and more environmentally friendly, not only at their manufacturing stage but also at their products' useful and EOL stages, there appears to be no such burden on the auxiliary companies. Our conclusion is based on an elaborate survey conducted during the fall of 2004 of Spanish auxiliary companies with questions about the characteristics, environmental practices and reverse logistics related activities carried out by the companies.

    2009-09-01

    Motorcyclists have been reported to be more likely to die in a motor vehicle collision (MVC) than automobile occupants. With the recent increase in the pump price of gasoline, it has been reported that people are switching to motorcycles as main modes of transportation. This study evaluated the association between motor vehicle collision-related injury and mortality rates and increases in gasoline prices for occupants of automobiles and riders of motorcycles. There were an estimated 1,270,512 motorcycle MVC and 238,390,853 automobile MVC involved occupants in the U.S. from 1992 to 2007. Higher gasoline prices were associated with increased motorcycle-related injuries and deaths; however, this association no longer remained after accounting for changes in the number of registered vehicles. The current study observed that, while the number of injuries and fatalities in motorcycle-related MVCs increase with increasing gasoline price, rates remained largely unchanged. This suggests that the observed increase in motorcycle-related injuries and fatalities with increasing gasoline price is more a factor of the number of motorcycles on the road rather than operator characteristics.

    We propose a mathematical model for calculating thermal loods of parts of the cylinder-piston group of the automobile engine operating under unstable conditions in its complete life cycle. Methods have been described for calculating the boundary conditions to determine the thermal state of the parts of the cylinder-piston group of such an engine with the use of theoretical formulas, empirical and semiempirical relations, and tabulated data. In modeling, we calculated the work of all systems of the engine (pumps, pipelines, heat exchangers) influencing directly or indirectly the thermal state of its cylinder-piston group. The nonstationary thermal state was calculated once in the operating cycle of the engine with the use of the cycle-averaged values of the local heat transfer coefficients and the resulting temperature of the medium. The personal computer counting time for one time step of a transport diesel engine of typical design with a number of units of the order of 500 was 5 s.

    Wastewater from automobile garages and workshops is an important contributor to the water pollution. Oil and grease is one of the major content of wastewater from vehicle garages. Wastewater from a public transport depot at Thrissur district in Kerala, India was collected for the study. A batch reactor has been devised to assess the efficacy of electrocoagulation in removing oil and grease from the wastewater. Aluminium and iron were tested as the anode material with stainless steel as cathode. Experiments were conducted to investigate the effect of various operating parameters such as current density, pH, time and salt concentration on oil and grease removal. The results shown that aluminium is superior to iron in removing the oil and grease from the wastewater. The reactor with aluminium as anode was able to remove 90.8 % of the oil and grease at a current density of 0.6 A/dm2 in 15 minutes. The calculated specific energy consumption is also less for aluminium in comparison with iron.

    CERN is partnering with Services Industriels de Genève (SIG) in an environmentally friendly initiative to acquire cars running on natural gas. The first forty vehicles will arrive at CERN around mid-February, and enter service in March.   On 3 February 2011 CERN, represented by Steve Myers at the FEDRE Forum, was awarded the mobility prize. CERN currently has approximately 800 vehicles in use at its different sites. Véronique Marchal, head of Site Services in the GS Department, explains: “Our fleet includes a great variety of vehicles, from small Category A cars for staff to utility/transport vehicles. The decision to acquire cars running on natural gas is part of our strategy of diversifying CERN's automobile fleet so as to make it more environmentally friendly.” The new cars are actually bi-fuel, which means that they will have two tanks: one for regular fuel and one for compressed natural gas (CNG). “This kind of car is a little more exp...

  1. Transportation technology transitions and macroeconomic growth -- Contemporary evidence

    Energy Technology Data Exchange (ETDEWEB)

    Santini, D.J.

    1994-12-31

    This paper presents international and temporal extensions of evidence for a theory developed by the author concerning the interaction of transportation technology transitions and macroeconomic growth. The period 1970 to the present is examined for the nations of Japan, the US, and Europe (France, Germany, Italy and the United Kingdom collectively). An addition to the abstract logic supporting the general arguments of the theory is also presented. The theory has been developed concerning the role of significant transportation technology transitions as a cause of significant macroeconomic declines in nations for which the manufacture of transportation vehicles (ships, locomotives, and automobiles) is a dominant economic activity. The theory offers an explanation for periods of pronounced multiyear decline in economic growth rate--sometimes called depressions and sometimes called stagnations. One purpose of this paper is to explore whether or not Japan and Europe have each recently experienced a multiyear event of this type. In the theory and the evidence presented for it, environmental regulation of transportation vehicles has been shown to be an initiating cause of significant technical change, with sharp, sustained fuel price increases being a second frequent initiating cause. These causes of significant technical change, and their possible consequences, are potentially important considerations for those proposing policies to deal with global warming, since both fuel economy regulation and fuel price increases have been recommended by policy analysts as means to reduce transportation`s contribution to global warming. The theory has been offered and supported by publications developing mathematical models and examining US historical evidence consistent with the theory.

    Today’s automobiles depend upon mechanical systems that are crucial for aiding in the movement and safety features of the vehicle. Various safety systems such as Antilock Braking System (ABS) and passenger restraint systems have been developed to ensure that in the event of a collision be it head on or any other type, the safety of the passenger is ensured. On the other side, manufacturers also want their customers to have a good experience while driving and thus aim to improve the handling and the drivability of the vehicle. Electronics systems such as Cruise Control and active suspension systems are designed to ensure passenger comfort. Finally, to ensure optimum and safe driving the various components of a vehicle must be manufactured using the latest state of the art processes and must be tested and inspected with utmost care so that any defective component can be prevented from being sent out right at the beginning of the supply chain. Therefore, processes which can improve the lifetime of their respective components are in high demand and much research and development is done on these processes. With a solid base research conducted, these processes can be used in a much more versatile manner for different components, made up of different materials and under different input conditions. This will help increase the profitability of the process and also upgrade its value to the industry.

  16. Comparative Frictional Analysis of Automobile Drum and Disc Brakes

    H.P. Khairnar

    2016-03-01

    Full Text Available In the present work, a comparative frictional behaviour of drum brakes and disc brakes in automobiles has been investigated. The influential factors; contact force and friction radius were modeled for the estimation of the friction coefficient for drum as well as disc brakes. The effect of contact force and friction radius is studied with varying conditions of parameters; longitudinal force, caliper force and torque on piston side as well as non-piston side. The numerical results obtained have been compared with the similar obtained from virtual Matlab/Simulink models for drum and disc brakes. The results evidenced that friction radius predominantly affects brake pressure and thus the friction coefficient, also the increase in contact force resulted with decrease in friction coefficient both for drum and disc brakes. Further it has been found that disc brakes exhibit gradual decrease of friction coefficient due to the equitable distribution of braking effort while drum brake presents sudden variations in friction coefficient. It can be revealed that frictional behaviour of disc brake is more consistent than drum brake.

    The automotive catalytic converter reduces or eliminates the emission of various chemical species (e.g. CO, hydrocarbons, etc.) that are the products of combustion from automobile exhaust. However, these units are only effective once they have reached operating temperature. The design and placement of catalytic converters has changed in order to reduce both the quantity of emissions and the time that is required for the converter to be effective. In order to compare the effectiveness of catalytic converters, time-resolved measurements were performed on several vehicles, including a 2010 Toyota Prius, a 2010 Honda Fit, a 1994 Honda Civic, and a 1967 Oldsmobile 442 (which is not equipped with a catalytic converter but is used as a baseline). The newer vehicles demonstrate bot a reduced overall level of CO and hydrocarbon emissions but are also effective more quickly than older units. The time-resolved emissions will be discussed along with the impact of catalytic converter design and location on the measured emissions.

    To improve the photocatalytic degradation properties of titanium dioxide (TiO 2 ) used as raw materials for purifying automobile exhaust (AE), the vanadium (V)-doped TiO 2 samples were prepared. The photocatalytic degradation efficiencies of V-doped TiO 2 to each component in AE were evaluated under ultraviolet (UV) and visible light irradiation, respectively. Results indicated that the photocatalytic activity of V-doped TiO 2 to AE was higher than that of pure TiO 2 , and the optimal V dopant content of TiO 2 was 1.0% under UV light irradiation. The degradation efficiencies of V-doped TiO 2 to NOx and HC were higher than those to CO 2 and CO in AE because of the reversible reaction between CO 2 and CO. In addition, it was found that the photocatalytic degradation efficiencies of V-doped TiO 2 to each component in AE were also increased under visible light irradiation. The V-doped TiO 2 also showed higher degradation efficiencies to NOx and HC than those to CO 2 and CO under visible light irradiation. The V doped TiO 2 presented higher photocatalytic activity to CO 2 than that to CO, but the reversible reaction between CO and CO 2 was not found under visible light irradiation. The photocatalytic reactions of pure and V-doped TiO 2 samples to each component in AE followed the first order kinetic pathway under the two light irradiations. It is concluded that the V doping is a feasible method to improve the photocatalytic degradation properties of TiO 2 to AE for air purification, developing a sustainable environmental purification technology based on TiO 2 materials.

    For decades, asbestos-containing gaskets were used in virtually every system that involved the transport of fluids or gases. Prior to the mid-1970s, some automobile exhaust systems contained asbestos gaskets either at flanges along the exhaust pipes or at the exhaust manifolds of the engine. A limited number of automobile mufflers were lined with asbestos paper. This paper describes a simulation study that characterized personal and bystander exposures to asbestos during the removal of automobile exhaust systems (ca. 1945-1975) containing asbestos gaskets. A total of 16 pre-1974 vehicles with old or original exhaust systems were studied. Of the 16 vehicles, 12 contained asbestos gaskets in the exhaust system and two vehicles had asbestos lining inside the muffler. A total of 82 samples (23 personal, 38 bystander, and 21 indoor background) were analyzed by Phase Contrast Microscopy (PCM) and 88 samples (25 personal, 41 bystander, and 22 indoor background) by Transmission Electron Microscopy (TEM). Only seven of 25 worker samples analyzed by TEM detected asbestos fibers and 18 were below the analytical sensitivity limit (mean 0.013 f/cc, range 0.001-0.074 f/cc). Applying the ratio of asbestos fibers:total fibers (including non-asbestos) as determined by TEM to the PCM results showed an average (1 h) adjusted PCM worker exposure of 0.018 f/cc (0.002-0.04 f/cc). The average (1 h) adjusted PCM airborne concentration for bystanders was 0.008 f/cc (range 0.0008-0.015 f/cc). Assuming a mechanic can replace four automobile single exhaust systems in 1 workday, the estimated 8-h time-weighted average (TWA) for a mechanic performing this work was 0.01 f/cc. Under a scenario where a mechanic might repeatedly conduct exhaust work, these results suggest that exposures to asbestos from work with automobile exhaust systems during the 1950s through the 1970s containing asbestos gaskets were substantially below 0.1 f/cc, the current PEL for chrysotile asbestos, and quite often were

    In any industry, heating, cooling and compressed air the costliest part, which affects the production cost of any product. There are three types of indirect heat requirement or the requirement of heat can be divided in the three main categories. (1) low temp. 40 - 60 Deg. (2) Medium temp. 80 - 150 deg. (3) High Temp applications - above 150. Solar Flat Collectors have been proven for the use of solar energy for medium temp. application in hotels, boiler feed water preheating, dairy for pasteurization and some other indirect heating applications. There is another neglected area of application of Solar Flat Plate collector is heat treatment for powder coating plants where heat requirement is bet 50 Deg C - 70 Deg C. In any automobile industry the aesthetic or look of the vehicle place a very important role as far as the sale is concern (after the mechanical performance). The aesthetic means the body and colour of the vehicle. To get a long lasting good quality color, the powder coating procedure plays a major role. Before powder coating there is requirement of different chemical treatment for the removal of rust, grease and other cleaning of the specific sheet metal body parts. The time duration and chemical composition is depends on the selection of body material. A proven method of a chemical treatment is seven / eight tank process. The common system of heating chemicals is by way of electrical heaters, by diesel or other fuel fired boilers. This increases the cost of heat treatment process due the high cost of electricity (for industries rate of electricity is 1.5 to 2 times than the domestic rate) or oils. This can be replaced by Solar water heating system which can efficiently generate the temp of liquid upto 85 Deg C. (orig.)

    Polybrominated diphenyl ethers (PBDEs), a class of brominated flame retardants, have been widely used in many applications in industry such as automobiles, textiles, and electronics. This study focused on a quantitative substance flow analysis (SFA) of PBDEs in automobiles in order to identify their flow by life cycle and treatment pathways of PBDEs-containing materials in end-of-life vehicles (ELVs) in Korea. In addition, this study has estimated environmental releases of PBDEs in automobiles by life cycle in Korea. During this study, PBDEs were analyzed for the samples collected from several ELVs treatment facilities using X-ray fluorescence and gas chromatography/mass spectrometry (GC/MS) methods. The system boundary for SFA of PBDEs ranged from manufacturing/trade to disposal stage of automobiles by life cycle. Based on the result of the SFA, it was found that the amount of PBDEs in automobiles were the highest in use stage (7748ton/year), followed by production stage (1743ton/year) in 2014. In disposal stage, automobile shredded residues (ASR) and seat fabrics were the main components with relatively high levels of PBDEs in ELVs. The major treatment methods of such components included incineration (84%), energy recovery (9%), and landfilling (6%). This research indicates that PBDEs were emitted the highest amount from interior components during the use stage of automobiles, followed by recycling processes such as dismantling and shredding. This study suggests that PBDEs in ASR and seat fabrics should be properly managed to prevent the widespread dispersion in the environment. Copyright © 2016 Elsevier B.V. All rights reserved.

    Atmospheric iron (Fe) plays an essential role in the carbon cycle, affecting the Earth's energy balance and human health. Fe catalyzes oxidations of organic carbon species and serves as a limiting nutrient for phytoplankton in about half of the world's oceans. Wind-blown dust is the major source of atmospheric insoluble Fe while urban areas are correlated with relatively high percentages of soluble Fe. The occurrence of elevated levels of soluble Fe near urban and industrial regions suggests a correlation between Fe solubilization and organic combustion products, including polycyclic aromatic hydrocarbons (PAH). Fossil fuel consumption for internal combustion engines produce atmospheric PAH as a major component of automobile exhaust. Under light, PAH transform into oxidized components such as ketones and carboxylic acids. For example, phthalic acid (formed from naphthalene) inhibits Fe oxidation reactions and therefore may contribute to Fe reduction and increased solubility. The wind-blown dust and PAH-containing combustion products undergo long-range atmospheric transport leading to mixing and metal-organic interactions. The current study focuses on how a saturated PAH suspension affects the production of soluble Fe. Reactions of soil-based Fe and saturated solutions of PAH are performed under controlled conditions simulating natural sunlight. Samples are analyzed by ICPMS for soluble Fe before and after solar exposure reactions; soluble Fe is separated from total Fe by filtration and total Fe by acid-assisted microwave digestion. Data indicate an increase in Fe solubility (1.2% to 4.2%) in the presence of PAH, as compared to soil in water alone, and an even greater increase in Fe solubility (4.2% to 8.4%) when exposed to solar radiation. Research is ongoing to determine the dependence of oxidized PAH on kinetic and overall Fe solubility.

    Full Text Available In this study, we have examined impacts of energy consumption, real GDP and population on the pollution from the automobile transport in Azerbaijan case. We employed annual time series data for the 1990-2014 time span. First the data tested for stationarity and then we employed the Autoregressive Distributed Lags Bounds Testing approach to cointegration. Estimation results indicated that population has significant impacts on the transport emission in Azerbaijan; however impacts of energy consumption are not trivial. Real GDP has statistically insignificant but positive impact over emission. Findings of the study may be useful in making appropriate decisions in the fields of diminishing atmospheric pollution from automobile transport.

    In the Chicago six-county metropolitan area, the number of registered vehicles grew by over 800,000 vehicles in the 1980s; by contrast the population increased by just over 150,000 during the same time. This ratio of growth in automobiles versus population (five to one) has contributed to overall increases in travel, congestion and energy use. The objective of this report is to examine how and why this has occurred and what we might expect in the near future to address the growing traffic problems and energy use. Specifically, the focus is on energy use by household vehicles and other forms of passenger travel. Data on population trends, gasoline prices, commuting and transit use, and transportation energy use are presented and interpreted. Intelligent transportation systems and decreased single vehicle emissions are briefly described as methods to decrease congestion and pollution. 9 figs., 2 tabs.

    Proper management of fecal sludge has significant positive health and environmental externalities. Most research on managing onsite sanitation so far either simulates the costs of, or the welfare effects from, managing sludge in situ in pit latrines. Thus, designing management strategies for onsite rural sanitation is challenging, because the actual costs of transporting sludge for treatment, and sources for financing these transport costs, are not well understood. In this paper we calculate the actual cost of sludge management from onsite latrines, and identify the contributions that latrine owners are willing to make to finance the costs. A spreadsheet-based model is used to identify a cost-effective transport option, and to calculate the cost per household. Then a double-bound contingent valuation method is used to elicit from pit-latrine owners their willingness-to-pay to have sludge transported away. This methodology is employed for the case of a rural subdistrict in Bangladesh called Bhaluka, a unit of administration at which sludge management services are being piloted by the Government of Bangladesh. The typical sludge accumulation rate in Bhaluka is calculated at 0.11 liters/person/day and a typical latrine will need to be emptied approximately once every 3 to 4 years. The costs of emptying and transport are high; approximately USD 13 per emptying event (circa 14% of average monthly income); household contributions could cover around 47% of this cost. However, if costs were spread over time, the service would cost USD 4 per year per household, or USD 0.31 per month per household-comparable to current expenditures of rural households on telecommunications. This is one of few research papers that brings the costs of waste management together with financing of that cost, to provide evidence for an implementable solution. This framework can be used to identify cost effective sludge management options and private contributions towards that cost in other
