To provide a user with a more appropriate route.SOLUTION: A route search device for communicating with a user terminal comprises: a communication section that receives a search request including a departure point, a destination point, departure time or arrival time, and transmits a route from the departure point to the destination point to the user terminal; a storage section stores signal sub-area information including information obtained by associating a plurality of intersections respectively having a traffic signal with a sub-area to which each of the plurality of intersections belongs; and an information processing section that executes search processing for searching the route on the basis of the signal sub-area information so that the smaller the number of sub-areas to be passed through in the route, the smaller a cumulative total of link costs.SELECTED DRAWING: Figure 11
【課題】ユーザーに対して、より適切な経路を提供する。【解決手段】ユーザー端末と通信する経路探索装置であって、出発地点及び目的地点と出発時刻又は到着時刻を含む探索要求を受信し、前記出発地点から前記目的地点までの経路を前記ユーザー端末に送信する通信部と、それぞれ交通信号機を有する複数の交差点と、複数の前記交差点がそれぞれ属するサブエリアと、を対応付けした情報を含む信号サブエリア情報を記憶する記憶部と、前記信号サブエリア情報に基づいて、前記経路中において通過する前記サブエリアの数が少ないほど、リンクコストの累計が少なくなるように、前記経路を探索する探索処理を実行する情報処理部と、を備える。【選択図】図11
