PROBLEM TO BE SOLVED: To provide a vehicle width measurement system that highly precisely calculates the width of a vehicle even when tires on one side of the vehicle do not ride on a tread.SOLUTION: A tread riding position at which tires of a vehicle A ride on a tread placed on a lane L is acquired. A light emitter E2 disposed at a position at which the light emitter is close to the tread in a lane direction and installed on one side in a width direction of the lane emits inspection light toward the vehicle. A light receiver R2 disposed at a position at which the light receiver is close to the tread in the lane direction, installed on one side in the width direction, and receives reflected light of the inspection light emitted from the light emitter receives the inspection light. A range finder measures a distance from the light emitter to the vehicle on the basis of reception of the inspection light by the light receiver. A vehicle width calculator measures the width of the vehicle by using the tread riding position which is detected from information contained in a tread riding detection signal, and the distance which is detected from information contained in a range finding signal obtained from the range finder.SELECTED DRAWING: Figure 2
【課題】車両の片側のタイヤが踏板を踏み付けなかった場合でも、車両の車幅を精度高く算出する車幅計測システムを提供する。【解決手段】車線L上に設けられた踏板を車両Aのタイヤが踏み付けた際の踏板の踏み付け位置を取得し、踏板と車線方向に近接した位置に配置されて車線の幅方向一方側に設けられた発光部E2が、車両に向けて検査光を発光し、踏板と車線方向に近接した位置に配置されて幅方向一方側に設けられ、発光部の発光した検査光の反射光を受光する受光部R2が、検査光を受光する。測距部が受光部における検査光の受光に基づいて発光部から車両までの距離を測定する。車幅算出部が、踏み付け検知信号に含まれる情報から検出した踏み付け位置と、測距部から得た測距信号に含まれる情報から検出した距離とを用いて、車両の車幅を計測する。【選択図】図2
