To provide a technology capable of designating a proper travel route on the basis of information concerning a node.SOLUTION: Processing of calculating a segment route between adjoining nodes is carried out. In the calculation processing, when a certain condition is met for an object route, a sectorial arc that has as a start point coordinates of a start point of the object route and curves in the same direction as the curving direction of the object route is designated. Thereafter, a distance between end points is calculated. The distance between end points is a distance from coordinates of the end point of the object route to coordinates of the end point of the arc in the direction of a coordinate axis along which a preceding segment route extends. Thereafter, the entire arc is slid by the distance between end points in a direction which is parallel to the coordinate axis along which the preceding segment route extends and in a directing heading to the start point from the end point of the preceding segment route. The entire slid arc is designated as a new segment route substituting for the object route. The coordinates of the end point of the preceding segment route are altered to the coordinates of the start point of the slid arc.SELECTED DRAWING: Figure 11
【課題】ノードに関する情報に基づいて適切な走行経路を設定することのできる技術を提供する。【解決手段】隣り合うノードの間の区分経路を計算する処理が行われる。計算処理では、対象経路について一定の条件が満たされる場合、対象経路の始端の座標を始端として有し、かつ、対象経路のカーブ方向と同じ方向にカーブする扇形の弧が設定される。次に、終端間距離が計算される。終端間距離は、先行区分経路が延びる座標軸の方向における、対象経路の終端の座標から弧の終端の座標までの距離である。次に、弧の全体が、先行区分経路が延びる座標軸に平行な方向、かつ、先行区分経路の終端から始端に向かう方向に、終端間距離だけスライドさせられる。そして、スライド後の弧の全体が、対象経路に代わる新たな区分経路に設定される。また、先行区分経路の終端の座標が、スライド後の弧の始端の座標に変更される。【選択図】図11
