The Theory and Practice of Disaggregate Demand Forecasting for Various Modes of Urban Transportation

A major responsibility of transportation planners is to forecast those changes in travel demand induced by alternative transportation policies. In recent years, the range of analyzed policy alternatives and the range of considered policy questions have greatly expanded. Emphasis has shifted from long-run planning of highway networks to shortrun planning and to management of integrated multimodal transportation systems. These shifts have placed considerable strain on conventional forecasting tools, which were originally designed to address problems of highway network design.
