PROBLEM TO BE SOLVED: To provide a technique capable of providing easy-to-understand guidance of an exiting road even when another road is connected to an intersection in the direction nearly equal to the direction of the exiting road.SOLUTION: A route guidance system of the present invention comprises: road acquisition means acquiring a road to an intersection on a planned travel route on which a vehicle travels when approaching the intersection, an exiting road on the planned travel route to exit the intersection, and a non-exiting road which can exit the intersection but is not present on the planned travel route; and guidance means for guiding a relative position of the exiting road to the non-exiting road when the exiting road and the non-exiting road constitute a pair of parallel roads.SELECTED DRAWING: Figure 3 【課題】退出すべき道路とほぼ同様の方向に他の道路が交差点に接続している場合でも、退出すべき道路を分かりやすく案内できる技術の提供。【解決手段】本発明の経路案内システムは、交差点に進入する際に走行する走行予定経路上の進入道路と、前記交差点から退出する予定の前記走行予定経路上の退出道路と、前記交差点から退出可能であるが前記走行予定経路上に存在しない非退出道路とを取得する道路取得手段と、前記退出道路と前記非退出道路とが一対の並走道路を構成する場合、前記非退出道路に対する前記退出道路の相対位置を案内する案内手段と、を備える。【選択図】図３
