To suppress a traffic jam caused by a vehicle waiting for a right-turn at an intersection having no right turn exclusive lane.SOLUTION: A signal controller 200 receives sensor data from a monitoring sensor 130 to determine traffic conditions of each lane of an intersection 110 based on the sensor data. When right-turn waiting congestion caused by a vehicle 101 occurs in any one of the lanes, the signal controller 200 performs right-turn preferential control on the lane in which the right-turn waiting congestion is occurring. The right-turn preferential control is performed such that the state of a traffic signal for an oncoming lane 112 which is opposite to a traffic congestion lane 111 is switched to a red signal faster than under normal control and earlier than a traffic signal for the traffic congestion lane 111.SELECTED DRAWING: Figure 1
【課題】右折専用車線が無い交差点で右折待ちする車両を原因とする渋滞を抑制する。【解決手段】信号制御装置200は、監視センサ130からセンサデータを受信し、交差点110の各車線の交通状況を前記センサデータに基づいて判定する。車両101を原因とする右折待ち渋滞がいずれかの車線で起きている場合、信号制御装置200は、前記右折待ち渋滞が起きている車線に対して右折優先制御を行う。前記右折優先制御は、渋滞車線111に対向する対向車線112に対する信号機の状態を定時よりも早く且つ渋滞車線111に対する信号機よりも早く赤信号に切り替える制御である。【選択図】図1
