Zusammenfassung: | To provide a passage determination device capable of accurately determining whether a vehicle passes a determination object area.SOLUTION: A passage determination device includes: an area information acquisition section for acquiring information of a polygon area which is a virtual area being a polygon and regulated on a map concerning a determination object area and where an entrance side and an exit side are fixed about one or more sides of the polygon; a reception section for successively receiving probe information of an object vehicle; and a passage determination section for determining whether the object vehicle enters/leaves the polygon area based on a time history of a positioning position of the object vehicle to be indicated by the probe information, so as to determine that the object vehicle passes the determination object area when a combination of the entrance and exit determination results satisfies a predetermined condition.SELECTED DRAWING: Figure 1
【課題】車両が判定対象エリアを通過したか否かを精度よく判定することができる通過判定装置を提供する。【解決手段】通過判定装置は、判定対象エリアについて多角形で地図上に規定された仮想領域であって、前記多角形の一つ以上の辺について進入辺および退出辺が定められたポリゴンエリアの情報を取得するエリア情報取得部と、対象車両のプローブ情報を逐次受信する受信部と、前記プローブ情報に示される前記対象車両の測位位置の時刻歴から、前記対象車両が前記ポリゴンエリアに進入および退出したか判定し、進入および退出の判定結果の組み合わせが所定条件を満たした場合に、前記対象車両が前記判定対象エリアを通過したと判定する通過判定部と、を備える。【選択図】図1 |
