To provide a vehicle detector, vehicle detection method, and program capable of accurately detecting entry or passage of diverse vehicles.SOLUTION: A vehicle detector 1 includes plural projectors E disposed on one side in a width direction of a lane and aligned in a height direction, plural light receivers R opposed to the projectors in the width direction across the lane and aligned in the height direction while being paired with the respective projectors E, a light receiving signal acquisition unit 120 that acquires a light receiving signal signifying whether a light axis P linking detection light P, which is projected by the projector E, with the light receiver R which receives the detection light P is intercepted, and a detection signal output unit 130 that outputs based on the acquired light receiving signal a detection signal signifying whether a vehicle exists in the lane. The projectors E and light receivers R are arrayed so that the light axis P is formed to be inclined in the height direction with respect to a virtual line VL extending in the width direction on a road surface in the lane.SELECTED DRAWING: Figure 3

    【課題】多種多様な車両の進入及び通過を正確に検知可能な車両検知器、車両検知方法、及びプログラムを提供する。【解決手段】車両検知器1は、車線の幅方向の一方に配置され、高さ方向に複数配列された投光部Eと、車線を挟んで幅方向で投光部Eに対向し、各々の投光部Eと対をなして高さ方向に複数配列された受光部Rと、投光部Eが投光する検知光Pと検知光Pを受光する受光部Rとを結ぶ光軸Pが遮光されたか否かを示す受光信号を取得する受光信号取得部120と、取得された受光信号に基づいて、車線に車両が存在するか否かを示す検知信号を出力する検知信号出力部130と、を備え、投光部E及び受光部Rは、車線の路面上で幅方向に延びる仮想線VLに対して高さ方向に傾斜する光軸Pが形成されるように配列されている。【選択図】図3
