PROBLEM TO BE SOLVED: To reduce the possibility of the occurrence of a deadlock in a specific direction caused by the interaction of control timing of a plurality of adjacent signal devices.SOLUTION: A signal control device of the present invention comprises: means for detecting the number of first waiting vehicles and the number of leaving vehicles on a first approach lane where it is possible to leave in a specific direction at a first intersection where a first signal device to be controlled is installed; means for acquiring the timing information of a second signal device adjacent to the first signal device in a specific direction; and means for performing split addition control for changing, when a first condition is satisfied that the number of first waiting vehicles is larger than a first threshold and the ratio of the number of leaving vehicles to the number of first waiting vehicles is smaller than a second threshold, withdrawal from the first approach lane to a specific direction from "prohibited" to "permitted" in an addition period that overlaps a permission period in which is permitted withdrawal from a second approach lane for approaching a second intersection from a specific direction where the second signal device is installed.SELECTED DRAWING: Figure 1
【課題】隣接する複数の信号機の制御タイミングの相互作用によって生じる、特定の方向におけるデッドロック発生の可能性を低減する。【解決手段】制御対象の第1の信号機が設置された第1の交差点において、特定の方向へ退出可能な第1の進入レーンの、第1の待ち車両数及び退出車両数を検出する手段と、第1の信号機と特定の方向について隣接する第2の信号機のタイミング情報を取得する手段と、第1の待ち車両数が第1の閾値より大きく、且つ第1の待ち車両数に対する退出車両数の割合が第2の閾値より小さいという第1の条件を満たす場合に、第2の信号機が設置された第2の交差点に特定の方向から進入する第2の進入レーンからの退出が第2の信号機により許可される許可期間と重なりを有する追加期間において、第1の進入レーンから特定の方向への退出を禁止から許可に変更するスプリット追加制御を行う手段とを備える。【選択図】 図1
