Abstract

Both the geographic information system (GIS) and transportation modeling environments have seen continually developing analytic concepts and techniques. However, these developments have seldom resulted in the integration of GISs and transportation models. This paper explores the potential inherent in merging of these environments through a systematic investigation of the fundamental basis of integration. To do this, the traditional four step transportation modeling process is extended to include input and output steps. We then define functional components for GIS data handling ? data management, manipulation, and analysis. The steps of modeling are matched against the list of GIS data handling functions within a matrix?based framework. GIS functions that enhance a land?use based urban transportation modeling process are then categorized. Conclusions are drawn and directions for future developments are discussed.
