PROBLEM TO BE SOLVED: To provide a system for providing an evacuation route capable of finding an evacuation route with a disaster area and disaster victims' conditions taken into account even when a communication failure between a server and a portable terminal device occurs.SOLUTION: A server 10 acquires geographical statistical information (Sda) or performs a disaster simulation on the basis of current position information (Gda) sent from a portable terminal device 20. The information received by the server 10 is sent to the portable terminal device 20 as significant information (Mda) during normal times and the significant information (Mda) is stored in significant information storage means 250 in the portable terminal device 20, which includes surrounding situation recognition means 280 for recognizing disaster situations surrounding a portable terminal device user when a disaster occurs. When the disaster occurs, evacuation route search means 260 searches for the most suitable shelter and evacuation route for the user on the basis of the current position information (Gda), the significant information (Mda), and the surrounding disaster information recognized by the surrounding situation recognition means 280.

    【課題】サーバと携帯端末装置との間に通信障害が生じていても被災場所や被災者の状況を考慮して避難経路の探索を行うことができる避難経路提供システムを実現する。【解決手段】サーバ10では、各携帯端末装置20から送信される現在位置情報Gda等に基づいて地理的統計情報Sdaの取得や災害シミュレーションの実行が行われる。サーバ10で得られた情報は平常時に有意情報Mdaとして携帯端末装置20に送信され、当該有意情報Mdaは携帯端末装置20内の有意情報記憶手段250に保存される。携帯端末装置20には災害が発生した際の利用者周辺の被災状況を認識するための周辺状況認識手段280が設けられている。災害が発生すると、避難経路探索手段260は、現在位置情報Gda、有意情報Mda、及び周辺状況認識手段280によって認識された周辺被災情報に基づいて、利用者にとっての最適な避難所・避難経路の探索を行う。【選択図】図5
