NETWORK TRAFFIC FLOW ANALYSIS ASSUMING A DYNAMIC ROUTE GUIDANCE SYSTEM

A dynamic route guidance system is proposed as part of a major intelligent transportation system (ITS) project in Japan. In this paper, network simulation is described and the effect of advanced traffic control by dynamic route guidance is analyzed in the simulation model. The Metropolitan Expressway in Tokyo is used as a model for simulation, which consists of a complicated network. In this simulation model, vehicles are grouped into packets and each packet has an alternative route to its own destination. The network has some points called "bottleneck" where congestion occurs frequently, and each bottleneck has a capacity being the maximum number of vehicles that can go through per minute. In the case of traffic control, the packets which can choose alternative routes use the route whose sum of waiting time is shorter than that of the other route. With this traffic control, the travel time becomes shorter, and at each bottleneck, the waiting time is also shorter than in the case without traffic control. As another result, the variance of waiting time was calculated for all bottlenecks. Without traffic control, the variance of waiting time of all 38 points increases, and the congestion can be observed at some places. This result indicates that traffic control balances traffic flow throughout the network.
