This title was first published in 2000: Describes policy innovations in transportation system management, planning and operations in the US that explicitly address interactions between transportation demands and travel behaviour in a mixed economy. The author shows how travel demand and management programmes function in the context of transportation supply and demand, investment, technology, pricing, management and marketing policies and procedures, with examples of voluntary, market-based and regulatory approaches to transportation and activity system management and institutional change. The author describes a variety of evaluation methods and models designed specifically for TDM programmes, and how these can be used to better inform decision-makers and other stockholders in the process of transportation policy formulation. TDM programmes have serious potential to increase the efficiency of a wide variety of transportation systems. Institutional obstacles are likely to prevent full implementation in the near future, but partial efforts are underway and likely to continue and succeed, under proper circumstances.
