To provide a traffic signal control device capable of solving traffic congestion even in a case where traffic congestion in which a passage of at least one of a vehicle to turn left and a vehicle to move straight is disturbed by traffic congestion of a vehicle to turn right is being generated on an enter road of an intersection.SOLUTION: A traffic signal control device comprises: image acquisition means for acquiring images captured by an imaging apparatus which captures an image of a vehicle on an enter road and an image of a vehicle on a leave road; analysis means for analyzing a situation of traffic congestion in which a passage of at least one of a vehicle to turn left and a vehicle to move straight is disturbed by traffic congestion of a vehicle to turn right on the enter road and a situation of traffic congestion on a vehicle-to-turn-right leave road where a vehicle moving from the enter road into an intersection leaves the intersection by turning right; enter road traffic congestion determination means for determining the presence/absence of traffic congestion on the enter road; vehicle-to-turn-right leave road traffic congestion determination means for determining the presence/absence of traffic congestion on the vehicle-to-turn-right leave road; and signal control means for controlling a signal on the basis of a result determined by the enter road traffic congestion determination means and a result determined by the vehicle-to-turn-right leave road traffic congestion determination means.SELECTED DRAWING: Figure 12
【課題】交差点の進入路において右折車渋滞による左折車又は直進車のうち少なくとも一方の通行を妨げる渋滞が発生している場合においても、渋滞を解消することができる交通信号制御装置を提供する。【解決手段】交通信号制御装置は、進入路における車両の像と、退出路における車両の像とを撮像する撮像装置により撮像された画像を取得する画像取得手段と、進入路における右折車渋滞による左折車又は直進車のうち少なくとも一方の通行を妨げる渋滞の状況と、進入路から交差点に進入した車両が右折により退出した右折車退出路における渋滞の状況とを解析する解析手段と、進入路が渋滞しているか否かを判定する進入路渋滞判定手段と、右折車退出路が渋滞しているか否かを判定する右折車退出路渋滞判定手段と、進入路渋滞判定手段が判定した結果と、右折車退出路渋滞判定手段が判定した結果とに基づいて、信号機を制御する信号機制御手段とを備える。【選択図】図12
