Abstract
An application system is presented to implement the integration of microscopic traffic simulation and GIS, and a spatio-temporal data model is proposed as the solution for the integration. We mainly discuss the framework, spatio-temporal data model and dynamic map layer of integrative system. The representative microscopic traffic simulation system, MITSIM, is adopted as the model to analyze the simulation process. We realized the integrative system based on ArcGIS and MITSIM. It has been shown that integrating microscopic simulation and GIS is an efficient and feasible method to utilize spatial data storage, analysis, visualization and abundant spatial data in GIS for microscopic traffic simulation.
