PROBLEM TO BE SOLVED: To provide a navigation device or the like capable of suppressing an increase in toll and simplifying the process thereof when a travel route up to a destination is set taking into consideration a congestion on a toll road.SOLUTION: A navigation device 100 includes: a destination position setting part 32 for setting a destination; a map buffer 10 for storing map data including a cost as the passing time with respect to each of the plurality of links corresponding to the road; and a route search processing part 34 for searching a travel route by adding re-merging cost when merging again with a toll road of the same road classification as the toll road having passed once when searching the travel route up to a destination on the basis of the stored map and determining the travel route where the cost up to the destination is the most lowest.SELECTED DRAWING: Figure 1
【課題】有料道路上の渋滞を考慮して目的地までの走行経路の設定を行う際に、通行料の増加を抑制するとともに処理を簡略化することができるナビゲーション装置等を提供すること。【解決手段】ナビゲーション装置100は、目的地を設定する目的地設定部32と、道路に対応する複数のリンクのそれぞれについて通過時間としてのコストを含む地図データを格納する地図バッファ10と、格納された地図データに基づいて目的地までの走行経路を探索する際に、一度通過した有料道路と同じ道路種別の有料道路に再度合流する際に再合流コストを加算して走行経路を探索し、目的地に至るまでの最もコスト合計が小さい走行経路を決定する経路探索処理部34とを備える。【選択図】図1
