Analyses of Route Choice and Route Switching Behavior Using ETC data from Tokyo Metropolitan Expressway

The analyses of route choice behavior based on revealed preference (RP) data are rare because of the difficulty of observing route choice decisions in practice. On Tokyo metropolitan expressway, traffic surveillance and electronic toll collection (ETC) systems provide rich sources of traffic condition and behavior data. This paper analyzes route choice and route switching behavior using the observed route choice decisions collected from ETC data in the selected study area. Moreover, the paper identifies and evaluates the importance of attributes relating to traffic condition information and drivers’ traveling characteristics derived from both ETC and detector data.
