Traffic Volume Estimation using Probe-Car Data

Effective urban transportation planning requires clarification of the actual traffic demand in city. A probe car can effectively collect data on the traffic conditions of roads where traffic detectors have not been installed. The probe car detects the travel time, but it does not directly measure the traffic volume on the road. Therefore, a method to estimate traffic volume using probe-car data is expected to be useful for determining the actual traffic volume of all roads in a city. The authors describe here a traffic volume estimation method that uses speed-density-flow models and the data collected from a probe car. The models are calculated for some representative roads, and the traffic volumes of roads for which the traffic volume cannot be directly observed are estimated using a model of a road with similar features. The authors evaluated the estimation accuracy of this method in Tokyo, Japan and Hanoi, Vietnam and found that the traffic volume was estimated with a mean error rate of approximately 30% using this method.
