PROBLEM TO BE SOLVED: To provide a communication terminal, a route search system and a computer program with which it is possible to quickly present a new guidance route based on map information of the latest version immediately after a motile entity leaves a guidance route.SOLUTION: Delivery guidance information 26 for guiding the movement of a vehicle in an area around a guidance route that is set in a communication terminal 6 is received from a guidance information delivery server device in order beginning with a place of departure and used for travel guidance and the received delivery guidance information is stored in a cache 47. When the vehicle leaves the guidance route, a return route for returning to the guidance route from the current position of the vehicle within the area for which the delivery guidance information 26 is stored in the cache 47 is searched using information included in the guidance information, and the searched return route is set to a new guidance route.SELECTED DRAWING: Figure 3

    【課題】移動体が案内経路から離脱した直後において最新のバージョンの地図情報に基づく新たな案内経路を迅速に案内可能にした通信端末、経路探索システム及びコンピュータプログラムを提供する。【解決手段】通信端末6において設定された案内経路の周辺のエリア内において車両の移動案内を行う為の配信案内情報26を、出発地側から順に案内情報配信サーバ装置から受信して走行案内に用いるとともに、受信した配信案内情報をキャッシュ47に記憶する。そして、車両が案内経路から離脱した場合には、配信案内情報26がキャッシュ47に記憶されているエリア内で車両の現在位置から案内経路へと復帰する復帰経路を、案内情報に含まれる情報を用いて探索し、探索された復帰経路を新たな案内経路に設定するように構成する。【選択図】図3
