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.

Signal control apparatus, signal control method and program

A signal control system is capable of acquiring an image of a road from a camera disposed around a road in a control target area and includes a passability determination part for determining passability of a road section starting from an intersection on a basis of an abnormality in an image photographed by the camera and a signal control part for controlling a traffic signal device disposed at an intersection included in the road section so as to prevent traffic from inflowing into a closed section.
