Abstract
1 min readThis chapter discusses various aspects of travel demand models, mainly passenger travel models, and offers some views on outstanding research issues. Developments are described in the following three broad classes of travel demand models: (1) traditional four-stage transport models, associated with large urban transport studies and characterised by aggregate and descriptive uses of data; (2) the microeconomic approach of travel choice behaviour, based on random utility theory and emphasising the explanation of behaviour at the individual level; and (3) the activity-oriented approach, based on more holistic research styles and viewing travel behaviour as patterns of behaviour occurring once a day or several times a day, related to differences in people's life styles and participation in activities. Two major priorities are indicated, on which research and development should concentrate during the 1990s. For the covering abstract see IRRD 874715.
