To provide a route search system that can search for a route of which operation can be managed easily.SOLUTION: A portable terminal 10, which functions as a route search system, includes: a point acquisition unit 21a for acquiring a place of start and a destination; and a route search unit 21b for searching for a route from the place of start to the destination which provides less differences in the travel time according to periods, on the basis of information on the statistics of the travel time of each road interval. The route search unit searches for a route based on the cost for each road unit, which is larger in road intervals with larger differences in the travel time according to periods than in road intervals with smaller differences.SELECTED DRAWING: Figure 1

    【課題】運行管理のしやすい経路を探索する経路探索システムを提供する。【解決手段】経路探索システムとして機能する携帯端末10は、出発地および目的地を取得する地点取得部21aと、道路区間毎の旅行時間の統計情報に基づいて、出発地から目的地に達する経路であって、期間による旅行時間の差が少ない経路を探索する経路探索部21bと、を備える。経路探索部は、期間による旅行時間の差が多い道路区間は、差が少ない道路区間よりコストが大きい、道路区間毎のコストに基づいて経路を探索する。【選択図】図1
