  • 道路ネットワークにおける不要な道路リンク同定のための一考察


In the city traffic flow, it is observed that a new additional road causes more terrible traffic jam although the new road was constructed for improving the traffic jam. The aim of this study is to determine the road that causes the traffic jam from the traffic data of the traffic simulator. The problem is formulated as the optimization problem in which the traffic amount is maximized with respect to the configuration of the road network. The present algorithm is applied to the simple numerical example. The simulation result shows that the present algorithm can determine the road link that causes the traffic jam.
