USING OPTICAL BEACON DATA TO INVESTIGATE DRIVER ROUTE CHOICE BEHAVIOR

This paper investigates route choice behavior of drivers in an actual traffic situation using optical beacon data and the factors influencing driver route choice behavior were also examined. An optical beacon, which is also called an infrared vehicle detector, is an innovative traffic device that performs two-way optical communication with vehicles that have a special on-board instrument. The optical beacon enables us to measure the travel time of each equipped vehicle between two beacons, and to trace the route that each equipped vehicle has traveled. The data of optical beacons were collected for seven origin-destination (OD) pairs in the Chiba prefecture, Japan. A main route and a secondary route were defined for each OD pair. The main route is the route that most vehicles use. The secondary route is the route that many vehicles use next to the main route. The results derived from this study can be summarized as follows. The difference in travel time between the main route and the secondary route was relatively small. The utilization rate of the main route seems to be influenced by the travel time and the travel speed on the main route. The difference in the route length and the difference in the number of right-turns per 1km had a strong influence on the utilization rate of the main route.
