A Study on the Effect of Traffic Informaiton by using Network Simulation

In this paper, a simulation model was constructed to reproduce ever-changing traffic situation on urban network. The model is microscopic with vehicles treated individually and is equipped with function of route guidance to evaluate the effect of traffic information on traffic condition. The network consists of nodes and links, and all the nodes are controlled by traffic signals. From some computational results on a small-scale network in central area of Ube city, it was found that it is possible to make the most of existing network and reduce total travel time by providing the newest and accurate traffic information . But it was also suggested that higher penetration rate may make the route guidance more important.
