To enable a vehicle approaching an alternating traffic section to smoothly and efficiently pass through the alternating traffic section.SOLUTION: When a vehicle C1 approaches an alternating traffic section while a traffic light 25A is green denoting an access permission state, an approaching vehicle detection sensor 29A detects this vehicle C1 and measures the speed v and distance x of the vehicle C1. A time t till the vehicle C1 enters the alternating traffic section is measured using the measured v and x, and the access permission state of the traffic light 25A is maintained until the time t elapses. Furthermore, when the vehicle C1 approaching the alternating traffic section goes out of the detection range of the approaching vehicle detection sensor 29A and the vehicle C1 can no longer be detected by the approaching vehicle detection sensor 29A, the access permission state of the traffic light 25A is maintained until the passage of the vehicle C1 is detected by a passing vehicle detection sensor 22A.SELECTED DRAWING: Figure 1

    【課題】交互通行区間への接近車両を円滑かつ効率良く該交互通行区間を通過させることを課題とする。【解決手段】信号機25Aが進入許可状態である青信号の場合に、車両C1が交互通行区間に接近してきたならば、接近車両検知センサ29Aは、この車両C1を検知して車両C1の速度v及び距離xを計測する。計測したv及びxを用いて、車両C1が交互通行区間に進入するまでの時間tを算出し、この時間tが経過するまでの間、信号機25Aの進入許可状態を維持する。また、交互通行区間に接近する車両C1が、接近車両検知センサ29Aの検知範囲からはみ出し、接近車両検知センサ29Aによる車両C1の検知が不可能となった場合には、通過車両検知センサ22Aが車両C1の通過を検知するまでの間、信号機25Aの進入許可状態を維持する。【選択図】図1
