This book breaks new ground in the studies of green transition. It frames the ongoing transformation in terms of a "battle of modernities" with the emerging vision of ecomodernity as the final destination. It also offers a systematic exploration of the potential for extensive transformation of carbon-intensive sectors - with a focus on energy and transport - towards a low or post-carbon economy. The book does so in a comparative perspective, by pointing to a diversity of techno-economic and institutional solutions in the mature Western economies, and in the rapidly growing East and developing South. The contributors highlight a broad spectrum of available alternatives as well as illuminate conflicting interests involved. They also demonstrate how solutions to the climate challenge require parallel technological and governance innovation. The book advocates a new, overarching vision and agenda of ecomodernity - based on a synergistic paradigm-shift in industry, politics and culture - to trigger and sustain the ecological innovation necessary to tip development in a green direction. This vision cannot be monolithic; rather, it should reflect the diverse interests and conditions of the global population. This book is aimed at researchers and postgraduate students of energy, transport, environmental and climate policies, as well as development, environment, innovation and sustainability.

Provides a unique review of the major spatial aspects of transport systems, a detailed analysis of transport problems in urban and rural areas, an evaluation of social and environmental impacts, and a planning and policy overview. Divided into four parts, each considering a different aspect of transport geography. The first part outlines the basic geography of transport and examines transport and spatial structures, focusing upon the varying contributions made by transport to industrial, agricultural and urban development. Part two moves to consider specific transport systems at both national and international scales, drawing on studies from industrialised and developing nations and discussing the effects upon transport of the political changes in the former USSR and Eastern Europe. The third part examines some of the many problems of transport and urban and rural areas using specific examples to illustrate the contrasting difficulties and evaluate current urban transportation planning methods.

Cars, Automobility and Development in Asia explores the nexus between automobility and development in a pan-Asian comparative perspective. The book seeks to integrate the policies, production forms, consumption preferences and symbolism implicated in emerging Asian automobilities. Using empirically rich and grounded analyses of both comparative and single-country case studies, the authors chart new approaches to studying automobility and development in emerging Asia.

As bicycle commuting grows in the United States, the profile of the white, middle-class cyclist has emerged. This stereotype evolves just as investments in cycling play an increasingly important role in neighborhood transformations. However, despite stereotypes, the cycling public is actually quite diverse, with the greatest share falling into the lowest income categories. Bicycle Justice and Urban Transformation demonstrates that for those with privilege, bicycling can be liberatory, a lifestyle choice, whereas for those surviving at the margins, cycling is not a choice, but an often oppressive necessity. Ignoring these "invisible" cyclists skews bicycle improvements towards those with choices. This book argues that it is vital to contextualize bicycling within a broader social justice framework if investments are to serve all street users equitably. "Bicycle justice" is an inclusionary social movement based on furthering material equity and the recognition that qualitative differences matter. This book illustrates equitable bicycle advocacy, policy and planning. In synthesizing the projects of critical cultural studies, transportation justice and planning, the book reveals the relevance of social justice to public and community-driven investments in cycling. This book will interest professionals, advocates, academics and students in the fields of transportation planning, urban planning, community development, urban geography, sociology and policy.

Inland waterways are a host for a mode of transport that is not as visible to the general public or as used as it once was. It is, however, generally perceived to be very important to our freight transport system today, although a closer look into the inland waterway transport system rebuts this perception and reveals the strengths and opportunities of this mode of transportation. This book gives the reader a thorough understanding of the current role of inland waterway transport as a freight transport system and its conditions. Drawing on case studies from across Europe, this text explores the economic, logistic, and technological and policy issues related to inland waterway transport and the challenges that changes in these areas present to this transport mode. It also explores the strategies for the inland waterway transport sector to secure and then enlarge its role in the future of freight transport. Inland Waterway Transport will be an invaluable source for students and researchers of transport studies. In addition, the book will be useful to policymakers and practitioners involved in its development. It may also appeal to wider readers with an interest in the fascinating business of inland waterway transport.

Transport Justice develops a new paradigm for transportation planning based on principles of justice. Author Karel Martens starts from the observation that for the last fifty years the focus of transportation planning and policy has been on the performance of the transport system and ways to improve it, without much attention being paid to the persons actually using - or failing to use - that transport system. There are far-reaching consequences of this approach, with some enjoying the fruits of the improvements in the transport system, while others have experienced a substantial deterioration in their situation. The growing body of academic evidence on the resulting disparities in mobility and accessibility, have been paralleled by increasingly vocal calls for policy changes to address the inequities that have developed over time. Drawing on philosophies of social justice, Transport Justice argues that governments have the fundamental duty of providing virtually every person with adequate transportation and thus of mitigating the social disparities that have been created over the past decades. Critical reading for transport planners and students of transportation planning, this book develops a new approach to transportation planning that takes people as its starting point, and justice as its end.

Much work has been done on port governance yet little has addressed intermodal terminal governance, despite the clear similarities. This book fills that gap by establishing a governance framework for situating analysis of intermodal terminals throughout their life cycle. A version of the product life cycle theory is amended with governance theory to produce a framework covering each stage of the terminal's life cycle, from the initial planning to the many decisions taken regarding the public/private split in funding mechanisms, ownership, selecting an operator, specifying KPIs to the operator, setting fees, earning profit, ensuring fair access to all rail service operators, and finally to reconcessioning the terminal to a new operator, managing the handover and maintaining the terminal throughout its life cycle. An institutional analysis of stakeholder relations, situated within a governance framework, illuminates these issues and enables not only conceptualisation and greater understanding of the geography of intermodal transport, but also decision-making and goal-setting by planners and policy makers. This book thus has three functions: first, as a textbook on the planning and operation of intermodal terminals; second, as a presentation of recent empirical research on intermodal terminal governance; third, as a framework for future research in which the broad field of analysis of intermodal transport can be viewed through a single lens and used to inform geographers, policymakers and planners.

The world is on the verge of an unprecedented increase in the production and use of biofuels for transport. The combination of rising oil prices, issues of security, climate instability and pollution, deepening poverty in rural and agricultural areas, and a host of improved technologies, is propelling governments to enact powerful incentives for the use of these fuels, which is in turn sparking investment. Biofuels for Transport is a unique and comprehensive assessment of the opportunities and risks of the large-scale production of biofuels. The book demystifies complex questions and concerns, such as thefood v. fuel debate. Global in scope, it is further informed by five country studies from Brazil, China, Germany, India and Tanzania. The authors conclude that biofuels will play a significant role in our energy future, but warn that the large-scale use of biofuels carries risks that require focused and immediate policy initiatives. Published in association with BMELV, FNR and GTZ.

In recognition of the importance of road safety as a major health issue, the World Health Organization has declared 2011-2021 the Decade of Safety Action. Several countries in Europe, North America, and Asia have been successful in reducing fatalities and injuries due to road traffic crashes. However, many low-income countries continue to experience high rates of traffic fatalities and injuries. Transport Planning and Traffic Safety: Making Cities, Roads, and Vehicles Safer offers a source book for road safety training courses as well as an introductory textbook for graduate-level courses on road safety taught in engineering institutes. It brings together the international experiences and lessons learned from countries which have been successful in reducing traffic crashes and their applicability in low-income countries. The content is based on lectures delivered during an international course on transportation planning and traffic safety, sponsored annually by the Transportation Research and Injury Prevention Programme (TRIPP) at the Indian Institute of Technology, Delhi. The book is interdisciplinary and aimed at professionals-traffic and road engineers, vehicle designers, law enforcers, and transport planners. The authors examine trends in performance of OECD countries and highlight the public health and systems approach of traffic safety with the vulnerable road user in focus. Topics include land use (transportation planning, mobility, and safety), safety education and legislation, accident analysis, road safety research, human tolerance to injury, vehicle design, safety in construction zones, safety in urban areas, traffic calming, public transportation, safety laws and policies, and pre-hospital care of the injured.

By 2050, two-thirds of the world's population will live in cities. To thrive, they will need efficient and sustainable forms of transport, but to achieve this, the financial incentives guiding urban transport operation must change - and change rapidly. Urban transport plays a critical role in determining the social, environmental and economic shape of cities. Improving Urban Access: New Approaches to Funding Transport Investment provide innovative ideas on how we might reorganize transport finance to ensure that it is suited to serving the social, environmental and economic principles that must guide future urban living. Continuing the work begun by its predecessor, Urban Access for the 21st Century, the authors assess the complexity of implementing new finance approaches and suggest ways to make positive and radical changes. Although the range of revenue raising options remain limited to users, indirect beneficiaries, and the general public, these can be recast to transform the way transport is paid for and therefore how its services are delivered. New finance models only succeed when they are intrinsically linked to the economic, social, cultural and political forces that create urban life. Together these volumes provide a starting point for the deeper research and policy design needed to successfully create urban transport finance systems that can address the challenges that 21st century cities present.

As affluence grows, it gets easier to travel faster and further. But research shows that, despite this, the average travel time in all societies remains steady at roughly an hour a day. The implication is that people are choosing to increase the distance they regularly travel, rather than opting for shorter journey times. While this clearly offers advantages in terms of reaching more desirable locations, the disadvantages are numerous - not least that of anthropogenic climate change, to which transport is the fastest growing contributor. However, the stability of travel time does not form part of the present conceptual framework of transport policy makers and professionals - consequently, misconceived decisions lead to unintended outcomes. In this intriguing book, David Metz examines the inadequacies inherent in the current thinking, along with the resulting problems, such as pollution, congestion and noise. He highlights the impact of the rapid increase in car use in China and India, and explores the general travel experience, public vs. private transport, and transport technology. In considering to what extent travel could be avoided, he arrives at a new paradigm to underpin sustainable transport policies, based on the fundamental characteristics of human mobility and focusing on quality, not quantity, of travel.

Based on a series of the most inspiring contemporary European examples of station redevelopment, this book will help planners and urban designers understand the specific and complex nature of station locations. Based on their extensive research, the authors, pioneers of studies in the field in the last few years, harness and expand the body of knowledge and present guiding principles and conditions for successful implementation of such planning projects.

Explore the Design and Operation of Urban Transport Interchanges Transport planners throughout the world can implement a range of policies to influence travelers' behavior, and encourage a move to public transport to achieve urban sustainability and social inclusion. At the same time population growth and urban sprawl exert their own pressures. Quality, accessible and reliable public transport through intermodal trips provides a solution. More than 20% of current commuting trips in Europe are intermodal, and typically between 20% and 30% of trip time is spent in intermodal transfer. Interchange stations are becoming important parts of city infrastructure where people spend time on social or economic activities. Includes Contributions from Numerous Experts in the Field CITY-HUBs: Sustainable and Efficient Urban Transport Interchanges focuses on urban transport interchanges from more than 20 European researchers demonstrates why transport interchanges are crucial for a seamless public transport system. It is based on a broad consultation process to stakeholders of 26 interchanges in 10 different countries, and on tailored surveys to travelers in five of them. It shows travelers how to reduce the negative aspects of transfer by improving information provision and by delivering convenient services and facilities. The book outlines the required steps from interchange planning to operation, and defines the functions, the design of the space for transfer, stay and services, and assesses the needs for different types of interchange. It introduces the evaluation of urban and economic impacts and the identification of users' perceptions to improve interchange efficiency. The most important factors from the user point of view are safety and security, transfer conditions, information, design, services and facilities, environmental quality and comfort. These define the efficiency of the interchange from two different perspectives: as a transport node and as a place. Packed with relevant data and offering step-by-step instruction, this book: Proposes innovative operating strategies for an intermodal services organization (i.e. innovative business model) Explores pilot and test case studies for defining interchanges good practice, and tests them in validation case studies Sets out urban planning guidelines for urban integration of a transport interchange As an advanced guide CITY-HUBs: Sustainable and Efficient Urban Transport Interchanges caters to transport operators, authorities, end-users' organizations and policy makers who are challenged to implement new urban interchanges or to upgrade them.

Does the development of new technology cause an increase in the level of surveillance used by central government? Is the growth in surveillance merely a reaction to terrorism, or a solution to crime control? Are there more structural roots for the increase in surveillance? This book attempts to find some answers to these questions by examining how governments have increased their use of surveillance technology. Focusing on a range of countries in Europe and beyond, this book demonstrates how government penetration into private citizens' lives was developing years before the 'war on terrorism.' It also aims to answer the question of whether central government actually has penetrated ever deeper into the lives of private citizens in various countries inside and outside of Europe, and whether citizens are protected against it, or have fought back. The main focus of the volume is on how surveillance has shaped the relationship between the citizen and the State. The contributors and editors of the volume look into the question of how central government came to intrude on citizens' private lives from two perspectives: identification card systems and surveillance in post-authoritarian societies. Their aim is to present the heterogeneity of the European historical surveillance past in the hope that this might shed light on current trends. Essential reading for criminologists, sociologists and political scientists alike, this book provides some much-needed historical context on a highly topical issue.

Urban land is a precious resource and originally published in 1961, Transportation and Urban Land aims to create an approach to analysing and projecting its uses with a particular focus on the household sector. By considering matters such as employment centres, organisation and technology of transportation and marginal valuation of residential space, Wingo develops a model to estimate how much land is required for residential land uses. This title will be of interest to students of Environmental Studies and professionals.

Mobilising Place Management makes an important contribution to the mobilities field by arguing for the need to rethink place management. It takes a point of departure in the mobilities turn and relational place thinking while exploring the relationship between place and mobility. In a world of increasing mobility and global competition between nations, cities and urban regions, the managing of places seems more relevant than ever before. By examining various examples of place and mobilities that range from the airport, rural village, tourist site, port-city to the city region, this book argues that the management of places can be informed and enhanced by installing a greater awareness and understanding of mobility. This insight could potentially improve the ability of current place management to translate a relational and mobilities-orientated thinking into concrete actions, instructions, interventions, designs, plans, policies and management control systems. The book will be essential reading for researchers, practitioners and students in the field of place management and across urban studies, planning, design, geography, sociology, tourism, transport and history.

Despite extensive efforts to understand the overall effect of urban structure on the current patterns of urban mobility, we are still far from a consensual perspective on this complex matter. To help build agreement on the factors influencing travel behaviour, this book discusses the influence of alternative urban structures on sustainable mobility. Bringing together two existing and complementary methods to study the relationship between urban structure and mobility, the authors compare two case studies with distinct urban structures and travel behaviour (Copenhagen and Oporto). Of particular concern is the influence of urban structure factors, namely land use and transport system factors, and motivational factors related to the social, economic and cultural characteristics of the individual traveller. The research presented in this book highlights the relevance of centrality in travel behaviour and in more sustainable travel choices. Different operational forms of the centrality concept are revealed as important: it is shown that more sustainable travel can be influenced by several urban structure factors and that no particular combination is required as long as a certain level of centrality is provided. Finally, the book concludes that urban structure can, on the one hand, constrain and, on the other hand, influence travel choice.

Indian diaspora has had a complex and multifaceted role in catalyzing, justifying and promoting a transformed urban landscape in India. Focussing on Kolkata/ Calcutta, this book analyses the changing landscapes over the past two decades of one of the world s most fascinating and iconic cities. Previously better known due to its post-Independence decline into overcrowded poverty, pollution and despair, in recent years it has experience a revitalization that echoes India s renaissance as a whole in the new millennium.

This book weaves together narratives of migration and diasporas, postmodern developmentalism and neoliberal urbanism, and identity and belonging in the Global South. It examines the rise of middle-class environmental initiatives and Kolkata s attempts to reclaim its earlier global status. It suggests that a form of global gentrification is taking place, through which people and place are being fundamentally restructured. Based on a decade s worth of field research and investigation in multiple sites - metropolitan centers connected by long histories of empire, migration, economy, and culture - it employs a multi-methods approach and uses ethnographic, semi-structured interviews as well as archival research for much of the empirical data collected.

Addressing urban change and policies, as well as spatial and discoursive transformations that are occurring in India, it will be of interest to researchers in the field of urban geography, urban and regional planning, environmental studies, diaspora studies and South Asian studies.

Helmut Holzapfel's Urbanism and Transport, a bestseller in its own country, now available in English, examines the history and the future of urban design for transport in major European cities. Urbanism and Transport shows how the automobile has come to dominate the urban landscape of cities throughout the world, providing thought-provoking analysis of the societal and ideological precursors that have given rise to these developments. It describes the transformation that occurred in urban life through the ongoing separation of social functions that began in the 1920s and has continued to produce today's phenomenon of fractured urban experience - a sort of island urbanism. Professor Holzapfel examines the vital relation between the house and the street in the urban environment and explains the importance of small-scale, mixed-use urban development for humane city living, contrasting such developments with the overpowering role that the automobile typically plays in today's cities. Taking the insights gained from its historical analysis with a special focus on Germany and the rise of fascism, the book provides recommendations for architects and engineers on how urban spaces, streets, structures and transport networks can be more successfully integrated in the present day. Urbanism and Transport is a key resource for architects, transport engineers, urban and spatial planners, and students providing essential basic knowledge about the urban situation and the challenges of reclaiming cities to serve the basic needs of people rather than the imperatives of automobile transport.

Revitalizing railways as a major sustainable transport mode in modern societies faces many issues and challenges. This in-depth overview places the importance of railways in the wider context of comprehensive sustainability, which encompasses sustainable development, social and economic equity and community livability. Some scholars have described the 21st century as a period of renaissance for railways and suggest this transport mode can fulfil people's desire for high mobility with low negative environmental, social, economic and financial impacts. In light of these new expectations for railways, in both passenger and freight transport worldwide, this book offers the latest research insights on the renewed interest about railway expansions and their wide-ranging environmental, socio-economic and even political implications.

Asian-Pacific Rim Logistics presents a wide span of material, geographically and conceptually, in considerable depth. Current conditions are presented with an historical context and up-to-date detail that will satisfy the specialist reader as well as those new to logistics and to Asian conditions. The coverage of logistics and policies within and between Japan, South Korea and China is particularly strong. The examination of developments in global logistics and of conditions in the extended Rim to include Australia and India, provides an interesting base from which to speculate about future directions in logistics.' - Trevor Heaver, University of British Columbia, Canada'This book is a tour de force on the dynamic complexities surrounding logistics operations in the Asian-Pacific Rim. Writing in a highly accessible fashion, Professor Rimmer systematically probes those dynamics that mould the complex protocols through the lens of structure and institutions. This is a not-to-miss book for anyone who wants to understand how global flows of goods, finance, information and people are relentlessly reshaped by local policies and logistics practices in countries of the Asian-Pacific region./ - Booi H Kam, RMIT University, Australia Encompassing China, Japan, South Korea and Southeast Asia, extending to Australasia and connecting with South Asia, the Asian-Pacific Rim forms the world's most dynamic economic region. Comprehending the region's logistical structure and its institutions is of pivotal importance for businesses, researchers and policy-makers. The flow of goods, people and information constitutes the global and local economic system. Through a unique analysis of this system and the transport and communications technologies that sustain it, Peter J. Rimmer provides a framework for identifying the multilayered networks and gateways in which the Asian-Pacific Rim s logistics are embedded. Highlighting important structural and institutional features, the role of corporations (money) and states (power) in configuring global and local markets is illustrated by case studies drawn from across the world s major economic regions. This book addresses evolving challenges for policy-makers, arising from the extension of manufacturing and retailing supply chains across national borders, and from globalizing logistics services. By deepening knowledge and viewpoints on these issues, the well-illustrated Asian-Pacific Rim Logistics is essential reading for students exploring global logistics, supply chain management, international business, transportation, freight logistics and development studies. Policy-makers and a new generation of logistics and supply chain professionals will also benefit from the insights into this dynamic region. Contents: Acknowledgements Preface 1.

This book will explore a new approach to airport planning that better captures the complexities and velocity of change in our contemporary world. As a result, it will lead to higher performing airports for users, business partners, investors and other stakeholders. This is especially pertinent since airports will need to come back better from the Covid-19 pandemic. The book explains the importance of articulating a clear strategy, based on a rigorous analysis of the competitive landscape while avoiding the pitfalls of ambiguity and 'virtue signalling'. Having done so, demand forecasts can be developed that resemble S-curves, not simple straight lines, that reflect strategic opportunities and threats from which a master plan can be developed to allocate land and capital in a way that maximizes return on assets and social licence. The second distinctive feature of this book is the premise that planning an airport as an island, a fortress even, does not work anymore given how interconnected airports are with other components of the transportation system, the economies and communities they serve and the rapid pace of social and technological change. In summary, the book argues that airport planning needs to move beyond its traditional boundaries. The book is replete with real examples from airports of all sizes around the world and includes practical advice and tools for executives and managers. It is recommended reading for individuals working in the airport business or the broader air transport industry, members of airports' board of directors, who may be new to the business, elected officials, policy makers and urban planners in jurisdictions hosting or adjacent to airports, regulators, economic development professionals and, finally, students.
