PROBLEM TO BE SOLVED: To properly execute a reconfiguration of a sub-area in a traffic signal control according to an actual traffic condition.SOLUTION: A traffic signal control device 5 includes: a cycle length candidate setting part 21 for setting candidates of a plurality of cycle lengths relating to a reconfiguration between sub-areas, respectively; an index value calculation part 22 for calculating an index value by a traffic flow simulation with respect to each of the candidate of the cycle length; and a sub-area configuration determination part 12 for determining the reconfiguration between the sub-areas based on the index value. The index value calculation part calculates the index value from the simulation up to the signal cycle finished immediately after exceeding the time equivalent to the generation cycle of control command information as a starting point after executing the simulation based on the signal cycles by the specified number of times based on the candidate of the larger cycle length from among the candidates of the cycle length set for the calculation object of the index value when calculating the index value for determining propriety of non-coupling in the reconfiguration between the sub-areas.SELECTED DRAWING: Figure 1

    【課題】交通信号制御におけるサブエリアの再構成を実際の交通状況に応じて適切に実行可能とする。【解決手段】交通信号制御装置5が、サブエリア間の再構成に関する複数のサイクル長の候補をそれぞれ設定するサイクル長候補設定部21と、サイクル長の候補の各々について、交通流シミュレーションにより指標値を算出する指標値算出部22と、その指標値に基づきサブエリア間の再構成を決定するサブエリア構成決定部12とを備え、指標値算出部は、サブエリア間の再構成における非結合の可否を判定するための指標値を算出する場合に、当該指標値の算出対象に対して設定されたサイクル長の候補のうちより大きなサイクル長の候補に基づき、信号サイクルに基づくシミュレーションを所定回数だけ実行した後を起点として、制御指令情報の生成周期に相当する時間を超えた直後に終了した信号サイクルまでのシミュレーションから指標値を算出する構成とする。【選択図】図1
