Since the September 11 attacks, America is safer, but we are not yet safe. We have done much to degrade al-Qaida and its affiliates and to undercut the perceived legitimacy of terrorism. Our Muslim partners are speaking out against those who seek to use their religion to justify violence and a totalitarian vision of the world. We have significantly expanded our counter terrorism coalition, transforming old adversaries into new and vital partners in the War on Terror. We have liberated more than 50 million Afghans and Iraqis from despotism, terrorism, and oppression, permitting the first free elections in recorded history for either nation. In addition, we have transformed our governmental institutions and framework to wage a generational struggle. There will continue to be challenges ahead, but along with our partners, we will attack terrorism and its ideology, and bring hope and freedom to the people of the world. This is how we will win the War on Terror.

This report describes many ways in which science and engineering can contribute to making the nation safer against the threat of catastrophic terrorism. The report identifies key actions that can be undertaken now, based on knowledge and technologies in hand, and, equally important, describes key opportunities for reducing current and future risks through longer-term research and development activities.

"Professor Burns has captured the essence of transportation security, one of today's most pressing concerns. As the rate of globalization and world trade increases, security and supply chain resilience are at the core of one‘s global transportation network. This is a timely and well written contribution to the industry." John A. Moseley, Senior Dir

Mobility is fundamental to economic and social activities such as commuting, manufacturing, or supplying energy. Each movement has an origin, a potential set of intermediate locations, a destination, and a nature which is linked with geographical attributes. Transport systems composed of infrastructures, modes and terminals are so embedded in the socio-economic life of individuals, institutions and corporations that they are often invisible to the consumer. This is paradoxical as the perceived invisibility of transportation is derived from its efficiency. Understanding how mobility is linked with geography is main the purpose of this book. The third edition of The Geography of Transport Systems has been revised and updated to provide an overview of the spatial aspects of transportation. This text provides greater discussion of security, energy, green logistics, as well as new and updated case studies, a revised content structure, and new figures. Each chapter covers a specific conceptual dimension including networks, modes, terminals, freight transportation, urban transportation and environmental impacts. A final chapter contains core methodologies linked with transport geography such as accessibility, spatial interactions, graph theory and Geographic Information Systems for transportation (GIS-T). This book provides a comprehensive and accessible introduction to the field, with a broad overview of its concepts, methods, and areas of application. The accompanying website for this text contains a useful additional material, including digital maps, PowerPoint slides, databases, and links to further reading and websites. The website can be accessed at: http://people.hofstra.edu/geotrans This text is an essential resource for undergraduates studying transport geography, as well as those interest in economic and urban geography, transport planning and engineering.

In the past few decades, the field of transportation has changed dramatically. Deregulation and greater reliance on markets and the private sector has helped to reconfigure the transport industries, while the rise of intermodal goods and global commerce has produced efficiencies of operation and a greater interdependence among transport modes.
