Structure of linkages between transport and land use

Abstract

It is widely accepted that there is a two-way relationship between land use and transport. The effects of land use on transport can be modeled at both aggregate and disaggregate levels using well-established methodologies. However, there is no established representation of the converse relationship. A number of models exist that represent this two-way relationship, and many of them have been compared within the research program of the International Study Group on Land-Use Transport Interaction (ISGLUTI). However, the results from that work suggest not only that many mechanisms represent the linkages, but also that their dynamic behavior is not well understood. This paper focuses on the analysis of these mechanisms, drawing on experience from the ISGLUTI study. The representation of the response to a change in transport costs is analyzed for three integrated land-use transport models in terms of such topics as modal choice, locational choice, car ownership and the effects on the location of physical infrastructure.
