PROBLEM TO BE SOLVED: To enable a driver to quickly and reliably recognize a pedestrian having a risk of collision even in a situation where it is difficult for the driver to recognize the presence of a pedestrian, such as at night, for example.SOLUTION: An on-vehicle terminal device determines a risk of collision based on position information of a pedestrian and position information of a vehicle, generates lighting instruction information for lighting an indicator light carried by a pedestrian who has been determined to have a risk of collision with a predetermined lighting color, and sends the lighting instruction information to a pedestrian terminal device over a communication between the pedestrian and the vehicle. The pedestrian terminal device receives the lighting instruction information transmitted from the on-vehicle terminal device and turns on an indicator lamp based on the lighting instruction information.SELECTED DRAWING: Figure 7
【課題】例えば夜間のように運転者が歩行者の存在を認識しにくい状況でも、衝突の危険性がある歩行者を迅速にかつ確実に運転者に認識させることができるようにする。【解決手段】車載端末装置は、歩行者の位置情報および車両の位置情報に基づいて衝突の危険性を判定し、衝突の危険性があると判定された歩行者が携帯する表示灯を所定の点灯色で点灯させる点灯指示情報を生成し、その点灯指示情報を歩車間通信で歩行者端末装置に送信し、歩行者端末装置は、車載端末装置から送信される点灯指示情報を受信し、その点灯指示情報に基づいて表示灯を点灯させる。【選択図】図7
