PROBLEM TO BE SOLVED: To provide a vehicle width measurement device that can be arranged even in a toll gate having a limited arrangement space, and also to provide a vehicle width measurement method and a program.SOLUTION: A vehicle width measurement device includes: a first vehicle detection section having a first light projection part capable of projecting first inspection light and a first light receiving part capable of receiving reflected light of the first inspection light; a vehicle detection determination section for detecting a vehicle on the basis of the reflected light of the first inspection light; a second vehicle detection section having a light projection part capable of projecting inspection light inclined toward a lane direction with respect to a width direction of a lane and a light receiving part capable of receiving reflected light of the inspection light; a reflection part for changing an advance direction of the inspection light by causing the inspection light projected from the light projection part; to be regularly reflected; and a vehicle width calculation section for measuring a vehicle width of the vehicle on the basis of a first detection result obtained by detecting the reflected light from a first side surface of the vehicle and a second detection result obtained by detecting the reflected light from a second side surface of the vehicle.SELECTED DRAWING: Figure 3

    【課題】設置スペースが限られている料金所にも設置可能な車幅計測装置、車幅計測方法、及びプログラムを提供する。【解決手段】車幅計測装置は、第一の検査光を投光可能な第一の投光部、及び前記第一の検査光の反射光を受光可能な第一の受光部を有する第一の車両検出部と、前記第一の検査光の反射光に基づいて前記車両を検出する車両検出判定部と、前記車線の幅方向に対し前記車線方向に向かって傾斜して検査光を投光可能な投光部、及び前記検査光の反射光を受光可能な受光部を有する第二の車両検出部と、前記投光部から投光された前記検査光を正反射させて前記検査光の進行方向を変更する反射部と、車両の第一側面からの反射光を検出した第一の検出結果と、前記車両の第二側面からの反射光を検出した第二の検出結果とに基づいて、前記車両の車幅を計測する車幅演算部と、を備える。【選択図】図3
