Abstract
This study deals with a discrete simulation of the traffic flow of highways. The target of this study is to support the management administaration of highway's coorparate by the scientific technique. Each and every automobile, which has individual behavioral characteristics, is discretely modeled and the traffic flows are simulated dynamically by time marching method. The highway road itself is modeled as network which consists of nodes and links. This study presents some examples of traffic simulations of Tomei Highway from the Tokyo tollgate to the Yaizu interchange which have 320,000 automobiles in one day. Finally the logistic efficiency is analyzed by the time-value cost methods.
