PROBLEM TO BE SOLVED: To allow a traffic weak to safely cross a cross-walk having a traffic-signal, and to inform the presence of the traffic weak the others.SOLUTION: A pedestrian protection system includes a wireless tag which is used by a pedestrian and transmits attribute information indicating whether the pedestrian is a traffic weak by wireless communication, and road side device 1 which is installed in a pedestrian traffic signal. The road side device 1 includes a tag communication unit 11 which directly communicates with the wireless tag by wireless communication; an extension instruction unit 104 which makes an instruction for extending lighting time of green light of the pedestrian traffic signal on the basis of a fact that the attribute information received from the wireless tag at the tag communication unit 11 indicates a traffic weak; and a center communication unit 12 which uploads position information of the traffic weak to a center, when the attribute information received at the tag communication unit 11.SELECTED DRAWING: Figure 3
【課題】交通弱者が歩行者用信号機のある横断歩道を安心して渡ることができるようにしつつ、その交通弱者の存在を他者に通知することを可能にする。【解決手段】歩行者に用いられ、歩行者が交通弱者であるか否かを示す属性情報を無線通信によって送信する無線タグと、歩行者用信号機に設置される路側機1とを含み、路側機1は、無線タグと直接的に無線通信を行うタグ通信部11と、タグ通信部11で無線タグから受信した属性情報が交通弱者であることを示すことをもとに、歩行者用信号機における青信号の点灯時間を延長させる指示を行う延長指示部104と、タグ通信部11で受信した属性情報が交通弱者であることを示す場合に、交通弱者の位置座標をセンタへアップロードするセンタ通信部12を備える。【選択図】図3
