PROBLEM TO BE SOLVED: To provide a server capable of estimating the time period taken for travelling on a path between a departure and destination that are desired by a user, and supplying the time period to the user.SOLUTION: The server of the present invention includes: interval travel time estimating means for calculating an interval travel time, which is the time period taken by a radio terminal for travelling between two points, on the basis of the positional information and time information of the radio terminal at the two points, which are received from the radio terminal; and path travel time estimating means for calculating a path travel time, which is the travel time of the path interconnecting a departure point and destination point specified by a communication terminal requesting path finding, on the basis of the sum total of the interval travel times of the intervals constituting the path.

    【課題】ユーザが所望する出発地から目的地までの経路を移動するのに掛る時間を高い精度で推定し、ユーザへ提供することが可能なサーバを提供する。【解決手段】本発明におけるサーバは、無線端末から受信した、2地点での当該無線端末の位置情報と時刻情報とに基づき、当該2地点の間の区間を当該無線端末が移動した時間である区間移動時間を算出する区間移動時間推定手段と、経路探索を要求する通信端末が指定した出発地点と目的地点を結ぶ経路の移動時間である経路移動時間を、当該経路を構成する区間の区間移動時間の合計から算出する経路移動時間推定手段とを有する。【選択図】 図2
