The subjects of transport and information systems have long been closely linked because they are both complements and substitutes for each other and thus offer potential for more efficient and productive traffic demand management. This important new collection examines the substitution and complementarity hypotheses as well as the impact of new information technology on transport and the increasing adoption of information technology in transportation systems. The volume is organised into five sections. Part I offers a history and overview of the subject, while part II examines the welfare implications of information provision for traffic demand management. Part III discusses the network analysis of intelligent transportation systems and part IV investigates the spatial impacts of information technology and telecommuting. Finally part V looks in detail at case studies. This fascinating new collection will be an essential source of reference to scholars, practitioners and students interested in the subjects of transport and information systems.
