PROBLEM TO BE SOLVED: To provide an evacuation route provision system capable of searching for an evacuation route in consideration of conditions of a disaster location and a disaster victim even when a communication failure occurs between a server and a portable terminal device.SOLUTION: In a server 10, on the basis of GPS information Gda and the like transmitted from respective portable terminal devices 20, geographical statistical information Sda is acquired or disaster simulation is executed. Information acquired by the server 10 is transmitted to the portable terminal devices 20 as significant information Mda at a normal time, and the significant information Mda is stored in significant information storage means 250 in the portable terminal devices 20. The portable terminal devices 20 comprise disaster information input means for inputting a condition of a user oneself or peripheral condition of the user at the time of disaster occurrence. When disaster occurs, evacuation route search means 260 searches for an optimal evacuation location and an evacuation route for the user on the basis of the GPS information Gda, the significant information Mda, and information input by the disaster information input means.

    【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GPS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自身の状況または利用者の周辺状況を入力するための災害情報入力手段が設けられている。災害が発生すると、避難経路探索手段260は、GPS情報Gda,有意情報Mda,および災害情報入力手段によって入力された情報に基づいて、ユーザー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
