To reduce a possibility of erroneous determination so as to accurately determine a possibility of reverse running at a specific intersection where two one-way roads intersect at a plane.SOLUTION: A reverse running determination system (1) that determines a possibility of reverse running at a specific intersection where a first one-way road and a second one-way road intersect in a plane level is comprised of: a turning behavior acquisition unit (13) for acquiring a turning direction and a predicted turning radius of an own vehicle for each prescribed cycle; and a reverse running determination unit (16) that determines that there is a possibility of reverse running when the turning direction of the own vehicle is on a third road side and the predicted turning radius is equal to or smaller than a specified radius.SELECTED DRAWING: Figure 3
【課題】2つの一方通行道路が平面交差する特定交差点において、誤判定の可能性を低減して逆走の可能性を的確に判定する。【解決手段】第1一方通行道路と第2一方通行道路とが平面交差する特定交差点での逆走可能性を判定する逆走判定システム(1)は、規定周期毎の自車両の旋回方向及び予測旋回半径を取得する旋回挙動取得部(13)と、自車両の旋回方向が第3道路側であり、かつ、予測旋回半径が規定半径以下である場合に逆走する可能性があると判定する逆走判定部(16)とを備える。【選択図】図3
