In Japan, infrared beacons have been introduced and installed in urban road networks since 1993. Therefore we can not only get UPLINK information from beacons each vehicles, which has in-vehicle units, but also gather traffic volume as usual. Meanwhile these beacons are arranged around 20 m from exit of each direction, so we are able to observe turn of each vehicle. In this paper, in order to use these results for traffic signal control, we collected turn of each vehicle that has in-vehicle unit from UPLINK information and estimated turn rate using traffic demands.
