In studies of personal travel in towns, recourse is frequently made to transport models. A transport model can be defined as an approximate representation of some aspects of the real world, usually by a set of mathematical equations but sometimes by a set of intuitive non-quantitative statements. This paper is concerned with the development of demand models for personal travel that accurately reflect our increasing knowledge of travel patterns in urban areas, and which can be used as an aid to answering some of the increasingly complex questions raised by policy issues that cover transport, land use, and social factors. |
