This title includes a number of Open Access chapters. This new book takes a nuanced look at building a sustainable transportation infrastructure and provides an overview of the harmful effect of various modes of transportation on the environment. The environmental impact of transportation is significant. Transportation is a major user of energy, it burns most of the world's petroleum, and is the fastest-growing contributor to carbon dioxide emissions. Although environmental regulations in many countries have reduced the individual vehicle's emissions, this has been offset by an increase in vehicles on the road and airways.

The book deals with urban transportation planning in light of environmental sustainability and social equity. It begins with a review of the Indian urban transportation system and the issues surrounding it, and discusses the alternatives and policy directions that are being considered. It examines all the environmental issues arising out of transportation as a sector and assesses the alternatives that can be considered to improve sustainability. Further, the book not only analyses transportation modes that cater to the travel needs of the poor, so as to make them more socially equitable, but also explores measures to promote them using a multi-criteria and multi-stakeholder approach. It addresses the barriers that are bottlenecks for the implementation of cleaner fuels and modes of transport and presents an incremental approach to tackle environmental concerns, including climate change, when planning transportation in the long term. Finally, it presents the dilemma of city administrators in choosing between strategies aimed at local pollution control and those aimed at limiting global emissions. This unique book provides a comprehensive overview of “sustainable transportation.” It discusses all the important elements that are essential to transportation planners and policy makers when planning a city’s transportation. Theoretical presentations augmented by case-specific research work and the methodology used in some of the modules, make it a valuable resource for researchers working at the forefront of this area.

One of the greatest challenges to be faced in the 21st century is to effect a well integrated and environmentally acceptable solution for urban transportation. Considerable technical developments have taken place in recent years with the emergence of new and more advanced vehicular and transportation systems. There is also increasing pressure on the government to resolve transportation problems which have such an important effect on our society.

Urban Transportation and Air Pollution synthesizes state-of-the-art methods on estimating near-road concentrations of roadway emissions. The book provides the information needed to make estimates using methods based on a minimal set of model inputs that can be applied by a wide range of users in many situations. Discussions include methods to estimate traffic emission under numerous urban driving conditions, the uncertainty of emission models, and the effects of road configurations, such as near-road solid barriers. Final sections present dispersion models that link traffic emissions with near road concentrations in urban environments. Addressing transportation-related environmental issues is extremely important as urban areas are constantly searching for ways to mitigate impacts from transportation sources. This book helps to explain dispersion models, a critical tool for estimating the impact of roadway emissions in cities. - Compiles and synthesizes the state-of-the-science methods for estimating roadway emissions - Demonstrates, with clear examples, how modeling methods reduce uncertainties in real-world problems - Emphasizes how local-scale, semi-empirical, steady-state modeling can be applied using only a small set of inputs - Offers an overview of the meteorology that governs air pollution dispersion in cities

Each chapter was specially commissioned from an acknowledged world expert on the topic.

Traditional transport planning has generated transport systems that propagate an unfair distribution of accessibility and have environmental and safety issues. This book highlights the importance of social and political aspects of transport policy and provides a methodology to support this approach. It emphasizes the importance of co-ordinating urban, transport and traffic planning, and addresses the major challenge of modifying the building and use of roads. The author makes suggestions for innovative and radical new measures towards an equitable and sustainable urban environment.

All the papers in this volume were presented at a conference on Transportation and Urban Life, held in Munich during the third week of September, 1975. The conference was sponsored by the Special Programme Panels on Systems Science and Human Factors of the Science Committee of the North Atlantic Treaty Organisation. The distinguishing characteristic of the conference and of this volume lies in the combination of systems science and human factors contributions in the field of urban transportation. The initiative for attempting such a synthesis came from the sponsors. It is increasingly realised that the complexity of contemporary problems which applied scientists are being asked to solve is such that the coordinated efforts of several disciplines are needed to solve them. The brief which we formulated for the conference and distribu ted in our international call for papers was as follows: "The conference is intended to highlight significant psycho logical, SOCiological and economic aspects of transportation and urban life and to present new techniques which can be applied to these aspects and their interfaces". Papers were invited in four topic areas: Communities (transportation problems in relation to social needs, residential planning, industry and c0l1lITlerce) ; Cities and large urban areas (the econOlnic environment, material fl~l, resources); Regional development and transportation (administration and management at the project and multiprogramme level); and Quality of life and transportation (noise, visual intrusion, severance, air pollution).
