To provide highly reliable detection of a scan type vehicle passing whose operation can be surely continued even when failure occurs.SOLUTION: A vehicle detector comprises: a first scan type vehicle detector and a second scan type vehicle detector for detecting a vehicle passing at a same position along a traffic lane; a vehicle passing determination unit for determining a vehicle passing based on vehicle detection information input by the first and the second scan type vehicle detectors; and an output source changeover unit for changing over an output source detector to be an output source of vehicle detection information used for vehicle passing determination of the vehicle passing determination unit between the first and the second scan type vehicle detectors.SELECTED DRAWING: Figure 3
【課題】障害が発生した場合にも確実に運用を継続することができる信頼性の高いスキャン式の車両の通過の検知を提供する。【解決手段】車両検知装置が、車線に沿った同じ所定位置で車両の通過を検知する第1のスキャン式車両検知器及び第2のスキャン式車両検知器と、第1のスキャン式車両検知器又は第2のスキャン式車両検知器から入力される車両検知情報に基づいて車両の通過を判定する車両通過判定部と、車両通過判定部が車両の通過判定に用いる車両検知情報の出力元となる出力元車両検知器を、第1のスキャン式車両検知器及び第2のスキャン式車両検知器の間切替える出力元切替部と、を備える。【選択図】図3
