To provide technology that can control expansion of the scale of accidents caused by abnormal driving, even when a vehicle is driven abnormally due to the occurrence of an abnormality.SOLUTION: A traffic signal management system that manages signal indications at traffic signals includes a communication device, a control unit, and a map database. A controller performs emergency control of the signal indications when information from a communicating vehicle includes abnormal driving information indicating the vehicle that is driven abnormally. In the emergency control, a future trajectory of the vehicle that performs abnormal driving is predicted based on the abnormal driving information. Then, based on map information and the future trajectory, emergency control signals are generated to temporarily prohibit traffic at intersections and pedestrian crossings on a road along the future trajectory. The emergency control signals are then transmitted to traffic signals to be controlled. The traffic signals to be controlled are the traffic signals at the intersections and pedestrian crossings on the roads along the future trajectory.SELECTED DRAWING: Figure 7

    【課題】異常の発生により車両が異常走行した場合においても、この異常走行に伴う事故の規模が拡大するのを抑えることが可能な技術を提供する。【解決手段】信号機の信号表示を管理する信号機管理システムは、通信装置と、制御装置と、地図データベースと、を備える。制御装置は、通信車両からの情報に、異常走行を行う車両の情報を示す異常走行情報が含まれる場合、信号表示の緊急制御を行う。緊急制御では、異常走行情報に基づいて、異常走行を行う車両の将来軌道が予測される。続いて、地図情報と、将来軌道とに基づいて、将来軌道に沿った道路上の交差点及び横断歩道における通行を一時的に禁止するための緊急制御信号が生成される。そして、緊急制御信号が制御対象信号機に送信される。制御対象信号機とは、将来軌道に沿った道路上の交差点及び横断歩道の信号機である。【選択図】図7
