To provide a technique capable of determining a possibility for a travel which is to leave an intersection, to be traveled reversely through relatively simple processing.SOLUTION: A reverse travel determination system 1 comprises: a ground object recognition section 11 for recognizing a relative position of a target ground object which is installed on a leaving road, to a target vehicle; a determination boundary setting section 12 for setting a determination boundary laterally dividing a frond region in a direction of travel of the target vehicle, at a position which is fixed with respect to a direction of the target vehicle; and a determination section 13 by which, in a case where left-hand traffic is determined by traffic rules, a left side is defined as a first side or in a case where right-hand traffic is determined by traffic rules, a right side is defined as the first side, an opposite side of the first side is defined as a second side and in a case where the position of the target ground object in the front region in the direction of travel is changed from the second side to the first side with respect to the determination boundary after the target vehicle enters an intersection and before leaving the intersection, it is determined that it is possible for the target vehicle to enter an opposite lane and to be traveled reversely.SELECTED DRAWING: Figure 1

    【課題】比較的簡単な処理で、交差点から退出する車両が逆走する可能性を判定することが可能な技術を実現する。【解決手段】逆走判定システム1は、退出道路に設置された対象地物の対象車両に対する相対位置を認識する地物認識部11と、対象車両の進行方向前方領域を左右に分割する判定境界を、対象車両の向きに対して固定された位置に設定する判定境界設定部12と、交通規則で左側通行が定められている場合には左側を、交通規則で右側通行が定められている場合には右側を第1側とし、第1側とは反対側を第2側として、対象車両が交差点に進入してから退出するまでの間に、対象地物の進行方向前方領域での位置が判定境界に対して第2側から第1側に変化した場合に、対象車両が対向車線に進入して逆走する可能性があると判定する判定部13と、を備える。【選択図】図1
