To provide a traffic signal control system which can appropriately perform signal control.SOLUTION: A traffic signal control system comprises: a plurality of traffic signal control machines; and a central device which notifies the plurality of traffic signal control machines of signal control commands, in which the central device has: an upper side control part which generates the signal control commands for every plurality of traffic signal control machines; and an upper side communication part which transmits the generated signal control commands to the plurality of traffic signal control machines, respectively, the plurality of traffic signal control machines have: lower side communication parts which receive the signal control command of an own machine; lower side control part which control a signal light device based on the received signal control commands; and lower side storage parts which store lower side accumulation data which is a data group of accumulating the received signal control commands of the own machine, and the lower side control parts control the signal light device based on the signal control command corresponding to a present date type and time among the signal control commands of the own machine included in the lower side accumulation data when poor communication is generated between it and the central device.SELECTED DRAWING: Figure 2
【課題】適切に信号制御を行うことができる交通信号制御システムを提供する。【解決手段】交通信号制御システムは、複数の交通信号制御機と、信号制御指令を前記複数の交通信号制御機に通知する中央装置と、を備える交通信号制御システムであって、前記中央装置は、前記信号制御指令を前記複数の交通信号制御機ごとに生成する上位側制御部と、生成した前記信号制御指令を前記複数の交通信号制御機にそれぞれ送信する上位側通信部と、を有し、前記複数の交通信号制御機は、自機の前記信号制御指令を受信する下位側通信部と、受信した前記信号制御指令に基づいて信号灯器を制御する下位側制御部と、受信済みの自機の前記信号制御指令を蓄積したデータ群である、下位側蓄積データを記憶する下位側記憶部と、を有し、前記下位側制御部は、前記中央装置との間で通信不良が発生した場合に、前記下位側蓄積データに含まれる自機の前記信号制御指令のうち、現在の日種及び時刻に対応する信号制御指令に基づいて前記信号灯器を制御する。【選択図】図2
