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.

Abstract: A signal control apparatus is connected to a plurality of traffic signals located on a road with a plurality of intersections having travel lanes with designated traffic classifications. The signal control apparatus comprises: means for detecting the number of vehicles staying in the travel lane or lanes of the same traffic classification among the travel lanes of the plurality of intersections; means for determining whether or not to extend or reduce signaling time for permitting traffic of the traffic classification of the travel lane or lanes based on the number of vehicles staying in the travel lane or lanes of the same traffic classification at the plurality of intersections and means for adjusting split of the plurality of traffic signals based on a result of the determination so as to extend or reduce the signaling time.

Abstract: A monitoring-control apparatus according to the present disclosure can improve safety inside a vehicle. In the monitoring-control apparatus, a monitoring information acquisition unit acquires monitoring information including at least one item out of vehicle information, intra-vehicular information, and extra-vehicular information of a vehicle being a monitoring target. An avoidance action formulation unit formulates a plurality of avoidance actions for the vehicle to avoid a collision, based on the monitoring information. For each of the plurality of avoidance actions, a degree-of-damage calculation unit calculates a degree of damage to the inside of the vehicle by the avoidance action, based on the monitoring information. An avoidance action instruction unit selects an avoidance action from among the plurality of avoidance actions, based on the degree of damage, and instructs the vehicle on the selected avoidance action.
