A Study on the application of the traffic flow model using the road detector data

Although traffic flow has so far been measured by the road detector, the probe car system is showing usefulness as a new measurement technique. When the road detector data and the probe car data that exists in a complementary relation are united, it seems that more accurate and suitable dissemination becomes possible. The present study expands spatially by uniting the road detector data with the probe car data, and is an examination of the calculation of the reliability index of more highly accurate OD travel time. The traffic state was reproduced by applying the road detector data on Tokyo Metropolitan Expressway by the traffic flow model, and the system to calculate the OD travel time based on it was constructed. Moreover, the system that easily extracted the road detector data and probe car data of the same time and same location on Tokyo Metropolitan Expressway was constructed. The data was compared and the relation was understood. However, it was clarified that the presumption system that used only the traffic flow model caused a problem with repeatable precision according to the study site.
