An Analysis of Traffic Variation on the Expressway to Measure the Effect of the Toll Change Considering the Difference of Expressway Use Pattern

Thanks to the introduction of ITS devices, one can get the massive and individual traffic data at lower cost. This study analyzes the traffic volume variation of the expressways by using the transaction record of the electric toll collection (ETC) system in Japan. The authors are to find the reactions to the drastic toll change that is recorded in the data. The travel demand model they applied is the ordinary state space model that estimates the traffic of the expressway varying day by day, by which they can consider the time series change of traffic volume. In addition to that model, the authors grouped the expressway users into five clusters based on the characteristics of Expressway use. They did so because the ETC transaction record includes the ID information. Then they applied the state space model to each cluster. They can find the difference of the estimated state of the state space model among the clusters and found the difference of responses of the toll change among the clusters. In most of the cluster, there is no change in the parameters after the drastic change of the toll, but in the rare user cluster, the authors found the drastic change of the estimated state of the traffic. This implies that the toll change affects the traffic volume according relative to the ratio of rare users.
