Verification of a Travel Time Estimation Method using Data obtained from the Toll Collection System

Abstract

, Non-membeer (Toshiba Corporation), Masao Kuwahara, Non-member (University of Tokyo IIS)Recently, travel time information is very important at a traffic control system. At present, travel time information is calculated by sensor data such as traffic counter data. However, this method can not apply to a road without sensors. Therefore, this paper verify a travel time estimation method using data obtained from the toll collection system by using actual data. This method mainly consists of a removing method of unusual data, such as extremely long travel time and so on, and a calculating method of a travel time estimation value. A travel time estimation value can be calculated by using this method in the low cost in the road without a sensor. Furthermore, this method was verified by using actual data obtained from an expressway. As a result, the travel time estimation value obtained from the toll collection system confirmed that it was the level which could be used as an actual results value. 52T.
