Abstract

This research analyzes the accuracy of travel time estimation and the OD variation on of the Tokyo Metropolitan Expressway (MEX) using electronic toll collection (ETC) data. The ETC data mainly consist of driver IDs and entrance times of the vehicles at on-ramps, which are measured when the vehicles automatically pay the toll at on-ramps. First,travel time between on and off ramps is examined by comparing the estimates from ETC data with one from conventional traffic detector data. Fairly good agreement of two kinds of travel times is observed. Second, the OD variations are examined based on the ETC data.It is found that the variance of a daily OD volume is approximately in proportion to the amount of daily OD volume, and the difference in OD variations between ETC users and non-ETC users is examined based of the variation of on-ramp entrance volume. As a result, the OD variation of ETC users may be slightly smaller than that of non-ETC users.(a) For the covering entry of this conference, please see ITRD abstract no. 0612AR242E.
