PROBLEM TO BE SOLVED: To effectively prevent a traffic accident due to use of a smartphone while walking.SOLUTION: A signal 101 of a crosswalk H is provided with a signal transmission device 3 for transmitting signal information including whether the signal 101 is in a red signal state to surroundings. A portable terminal 2 includes: a communication part for receiving the signal information; a location acquisition part for acquiring a location of a pedestrian M; a direction acquisition part for acquiring a direction in which the pedestrian M walks; a map information storage part for storing map information including a location of the signal 101; a determination part for determining whether the pedestrian M is on the verge of entering the crosswalk H in the red signal state or whether the pedestrian M will enter the crosswalk H in the red signal state if he/she keeps walking, according to the signal information, the location of the pedestrian M, the direction in which the pedestrian walks, and the map information; and an alarm part for giving an alarm when the determination part determines and predicts that the pedestrian enters the crosswalk.
【課題】歩きスマホによる交通事故を効果的に防止する。【解決手段】横断歩道Hの信号機101に、この信号機101が赤信号状態であるかを含む信号情報を周囲に送信する信号送信器3を備え、携帯端末2に、信号情報を受信する通信部と、歩行者Mの位置を取得する位置取得部と、歩行者Mの歩行方向を取得する方向取得部と、信号機101の位置を含む地図情報を記憶する地図情報記憶部と、信号情報と歩行者Mの位置と歩行者Mの歩行方向と地図情報とに基づいて、歩行者Mが赤信号状態の横断歩道Hに進入する直前か否か、更に歩行者Mがこのまま歩行を続けると赤信号状態の横断歩道Hに進入するか否かを判定する判定部と、判定部によって進入する直前と判定・予測された場合に、警報を発する警報部と、を備える。【選択図】図1
