To provide a disaster prevention system that can notify a vehicle of information about a disaster prevention when the disaster breaks out in a tunnel.SOLUTION: A tunnel disaster prevention system 200 and a navigation system 500 for notifying a disaster in a tunnel T1 comprises: a communication unit of a tunnel disaster prevention system-side server device 4 for receiving a receiver-side fire signal that shows the detection of a fire in the tunnel T1; and a tunnel disaster prevention system-side management unit and a navigation system-side management unit for outputting disaster prevention information about the fire in the tunnel T1 on the side of a vehicle running in the tunnel T1 or in front of the tunnel T1, based on the receiver-side fire signal the communication unit has received. The communication unit of the tunnel disaster prevention system-side server device 4 receives the receiver-side fire signal and an approach inhibition signal that shows the inhibition of vehicle approaching to the tunnel when the fire is detected in the tunnel. The tunnel disaster prevention system-side management unit and the navigation system-side management unit output the disaster prevention information when the communication unit of the tunnel disaster prevention system-side server device 4 receives both of the fire signal and the approach inhibition signal.SELECTED DRAWING: Figure 1

    【課題】トンネル内の防災に関する情報を車両側に伝達することが可能となる防災システムを提供すること。【解決手段】トンネルT1に関する防災を行うトンネル防災システム200及びナビゲーションシステム500であって、トンネルT1内で火災を検出したことを示す受信機側火災信号を受信する防災側サーバ装置4の通信部と、通信部が受信した受信機側火災信号に基づいて、トンネルT1内又はトンネルT1の手前を走行している車両側において、トンネルT1内の火災に関する防災情報を出力する防災側管理部及びナビ側管理部と、を備え防災側サーバ装置4の通信部は、受信機側火災信号と、トンネル内で火災を検出した場合において当該トンネルへの進入を禁止することを示す進入禁止信号とを受信し、防災側管理部及びナビ側管理部は、防災側サーバ装置4の通信部が火災信号及び進入禁止信号の両方を受信した場合に、防災情報を出力する。【選択図】図1
