PROBLEM TO BE SOLVED: To provide a technology to reduce the time required for determining driving in the wrong direction.SOLUTION: An acquisition part 22 acquires first information on a measured position of a vehicle. A derivation part 26 derives second information on the position of the vehicle through map matching processing between the first position information acquired in the acquisition part 22 and map data stored in a storage part 24. In the map data stored in the storage part 24, a link in which a U-turn is prohibited of a plurality of links is set as a U-turn prohibited link. When the second position information is included in the U-turn prohibited link, and a U-turn based on the first position information is detected, a determination part 28 determines driving in the wrong direction.SELECTED DRAWING: Figure 2

    【課題】逆走を判定するまでの期間を短縮する技術を提供する。【解決手段】取得部22は、測位された車両の第1位置情報を取得する。導出部26は、取得部22において取得した第1位置情報と、記憶部24に記憶した地図データとのマップマッチング処理により車両の第2位置情報を導出する。記憶部24に記憶した地図データでは、複数のリンクのうち、Uターンが禁止されたリンクがUターン禁止リンクとして設定される。判定部28は、第2位置情報がUターン禁止リンクに含まれ、かつ第1位置情報をもとにしたUターンを検出した場合に、逆走を判定する【選択図】図2
