The aim of this study is to report on the case study of traffic prediction using the dynamic traffic simulation including route choice model on Tokyo Metropolitan Expressway (MEX). Due to recent high demand for accurate travel time information by drivers, MEX has been developing the dynamic traffic simulation model. MEX provides instantaneous travel time by various types of Variable Message Sign Boards (VMS), and the accuracy of instantaneous travel time is relatively high in general traffic condition. However, in case of accidents, its accuracy goes down significantly. In this paper,an outline of the dynamic traffic simulation is presented, and case studies on MEX are shown. The results show that this dynamic traffic simulationis useful for MEX network, even though it requires more verification.
