Transportation systems have become critical in successfully dealing with urbanization, globalization and even the war on terrorism. These 32 articles are written for the benefit of policy-makers, business logicians, engineers, managers, and students and examine the current state of major modes of transportation, major policy issues, and best practices as illustrated by case studies from the US and other nations. Topics include the big questions about twenty-first century transportation, the state of major systems (air, trucking, ports, inland waterways and toll roads) and intelligent transport systems, the effects of federalism on transportation, including state highway and passenger rail programs and regional planning, spatial modeling, decentralization, aviation regulation, energy and privatization. Closing articles address the challenges of managing transportation systems as assets and the process of securing and protecting transportation, whether by air, land or sea.
