Outline of Final Research Achievements

A method of evaluating the risk is developed, which consists of traffic congestion risk, traffic accident risk, and environmental risk, when the network traffic flow breakdown phenomenon occurs. As for the evaluation of traffic congestion risk, we develop a network traffic simulation model which can deal with the demand change by incorporating the driver behavior model. The traffic accident risk and environmental risk are evaluated based on the output of the simulation model. A hysteresis analysis of the aggregated QK was carried out, and MFD on road networks in the center of the capital of 47 prefectures are analyzed for understanding their characteristics.
