PROBLEM TO BE SOLVED: To provide an emergency notification system which advises a train driver urgently about an emergency arising in a railroad crossing even if a user, that is, a first reporter, cannot move quickly and yet weakens a possibility that the emergency notification system is abused.SOLUTION: A railroad crossing emergency notification system comprises a terminal device, access point devices, a router, a railroad crossing information server, a railroad crossing controller and a special signal light emitter. When a user finds an emergency in a railroad crossing and operates the access point device to notify the emergency, this operation makes the terminal device send an emergency notifying signal containing a signal announcing the emergency in the railroad crossing and a validity signal to indicate validity of the sending terminal device. This notifying signal reaches the server through the access point devices and the router. The server functioning as a validity determination device judges the validity of the sending terminal device based on the validity signal contained in the notifying signal sent by the terminal device. If the server decides that the sending terminal device of emergency notification is valid, then the server makes the controller, that is, an alarm output device, deliver alarms to express that an emergency arises in the railroad crossing.SELECTED DRAWING: Figure 4

    【課題】踏切で危険が発生した場合に、通報者が迅速に移動できなくても、いち早く列車に危険を知らせることができ、かつ、危険通知の仕組みが悪用される可能性を低減させられるようにする。【解決手段】端末装置は、非常通知操作が行われた場合に、踏切内の異常を通知する非常通知信号に、端末装置の正当性を示す正当性情報を含めて送信する。正当性判定装置は、端末装置から送信された非常通知信号に含まれる正当性情報に基づいて、異常通知元の端末装置の正当性を判定する。異常通知元の端末装置が正当であると正当性判定装置が判定した場合、警報出力装置が、踏切内の異常を示す警報を出力する。【選択図】図4
