Globalization and technological innovation have changed the way people, goods, and information move through and about cities. To remain, or become, economically and environmentally sustainable, cities and their regions must adapt to these changes by creating cutting-edge infrastructures that integrate advanced technologies, communications, and multiple modes of transportation. <BR>The book defines cutting-edge infrastructures, details their importance to cities and their regions, and addresses the obstacles - technical, jurisdictional, financial, and social - to creating those infrastructures. Additionally, it explores issues behind the creation of new infrastructures: their integrated, technical components, the decision making involved in their creation, and the equity and environmental questions they raise.
