A Probe Data-Based Approach of Enhancing Traffic Flow Observation for Traffic Management Applications

This paper describes a study that is conducted to evaluate the feasibility of making use of probe data on road networks. The advantage of probe data is that it enables traffic administrators to observe traffic flow conditions of ordinary roads, including ordinary roads with no vehicle detectors installed. Furthermore it is possible to acquire the flow data of turning traffic at signalized intersections which has not been possible to obtain by detectors. In this study, the authors collected probe data of taxis traveling around Yokohama City, and estimated the travel time and ratios of turning traffic flows based on only probe data. It is found that the probe data can be significantly utilized for traffic management purposes such as signal control and information provision in spite of their sparseness. Moreover, the results suggest that if the data are accumulated for sufficiently long periods of time, the traffic flow conditions can be accurately estimated.
