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

Traffic-Related Air Pollution synthesizes and maps TRAP and its impact on human health at the individual and population level. The book analyzes mitigating standards and regulations with a focus on cities. It provides the methods and tools for assessing and quantifying the associated road traffic emissions, air pollution, exposure and population-based health impacts, while also illuminating the mechanisms underlying health impacts through clinical and toxicological research. Real-world implications are set alongside policy options, emerging technologies and best practices. Finally, the book recommends ways to influence discourse and policy to better account for the health impacts of TRAP and its societal costs. - Overviews existing and emerging tools to assess TRAP's public health impacts - Examines TRAP's health effects at the population level - Explores the latest technologies and policies--alongside their potential effectiveness and adverse consequences--for mitigating TRAP - Guides on how methods and tools can leverage teaching, practice and policymaking to ameliorate TRAP and its effects

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.

The issue of urban transportation, together with its inter-related environmental and social concerns, continues to rise up the agenda of all city authorities and central governments. Reflecting the wide range of research being carried out in many countries today, and highlighting urban transport systems, traffic control, accessibility and mobility, control and simulation, finance, air quality and noise, and social issues and safety, this volume features papers presented at the Ninth International Conference on Urban Transport and the Environment in the 21st Century. The material included should be of interest to engineers, scientists and managers who are involved in the planning and management of urban transportation and transport policy.

Quantifying the effect of transportation on urban air pollution is challenging because decisions to travel are endogenous to air quality. The spread of COVID-19 offers a unique opportunity for causal identification, as the pandemic directly affects decisions to travel and choices of transportation modes but has little direct effect on air pollution. Leveraging the number of COVID-19 infections and COVID-19-related queries to search engines as instruments, we quantify the effects of three public transportation subsectors (buses, railways, and taxis) and private vehicles on six primary air pollutants in 36 central cities of China. The results demonstrate that the negative effects of urban transportation on air quality are likely to be significantly underestimated without addressing endogeneity in the observational data. After addressing endogeneity, the findings show that every 1% increase in the passenger volume of public transportation and in the congestion index results in a 0.039% and 0.368% increase in the synthesized air pollution index. Further, our estimates indicate that the effects are heterogeneous across transportation modes and air pollutants. Notably, our work shows that air pollution shifts the demand from mass transportation (i.e., buses) to taxis, which tends to further aggravate pollution.

This book details the context within which policy decisions and objectives for the property tax system are made in the transitional economies of Central and Eastern Europe. It shows how these policy decisions evolve as a part of the transitional reforms still in process. This book offers the chance to review the experiences of transitional countries in initiating and implementing fiscal instruments during a decade of enormous transformations. The research for the case studies, included in this book, was sponsored by the Lincoln Institute of Land Policy.
