Abstract
A first sensor detects a vehicle present in a lane in which a vehicle entering an intersection from a first direction is able to cross an opposite lane and turn right or left, and a vehicle entering the lane. A second sensor measures a flow of traffic of an oncoming vehicle that travels in an opposite lane from a second direction, enters the intersection, and passes through the intersection. Traffic condition acquisition means acquires a traffic condition including a speed of the oncoming vehicle based on sensor information obtained from the second sensor. Traffic light control means controls a timing of a signal indication for facilitating the right turn or the left turn in signal indications of a first traffic light and a second traffic light, based on sensor information obtained from the first sensor and the acquired traffic condition.
