PROBLEM TO BE SOLVED: To provide a traffic light control device that can appropriately switch a display state of a signal display unit even when a control signal for switching the display state of the signal display unit is not received.SOLUTION: A traffic light control device comprises: a control unit 20 that switches a display state of a signal display unit 30 mounted to a traffic light 100 as a traffic light control device 100 on the basis of an image photographed by an imaging unit 10; and a power storage unit 42 that supplies power to each constituent provided in an own device. In a case of an electricity failure at a time of a disaster and the like, the traffic light control device is configured to appropriately switch the display state of the signal display unit on the basis of an amount of traffic for each vehicle lane.
【課題】信号表示部の表示状態を切り替えるための制御信号を受信できない場合であっても、信号表示部の表示状態を適切に切り替えることができる信号機制御装置を提供する。【解決手段】信号機制御装置100としての信号機100に取り付けられている信号表示部30の表示状態を、撮像部10により撮像された画像に基づいて切り替える制御部20と、自装置が備えている各構成に電源を供給する蓄電部42とを備える。災害時などにおいて停電した場合に、車線毎の交通量に基づいて信号表示部の表示状態を適切に切り替える。【選択図】図1
