Summary:PROBLEM TO BE SOLVED: To provide a road measurement system that can accurately identify measurement information arising from a structure of measurement information collected in the vicinity of the structure, and can accurately identify a measurement location of the measurement information.SOLUTION: A road measurement system S loaded in a vehicle 1 is configured to store video data from a video camera 2, acceleration data from an acceleration sensor 3, shape data from a surface shape sensor 4, scan data from a line scan camera 6, a GPS signal from a GPS receiver 7, speed data and distance data from a distance sensor 5, sound data from a microphone 9, and rutting-amount data from a rutting measuring instrument 10 in a storage device 83 in association with an acquisition time. When the acceleration data exceeds a reference value, a CPU 81 is configured to extract bridge number from the video data to associate an installation location of a joint 7 identified by the bridge number with a measurement location of the acceleration data. An inspection screen for conducting an inspection of the road is displayed on a display of a note PC 8. 【課題】構造物の近傍で収集された測定情報のうち、構造物に起因する測定情報を正確に特定できて、測定情報の測定位置を正確に特定できる道路測定システムを提供すること。【解決手段】車両１に搭載された道路測定システムＳは、動画カメラ２からの動画データと、加速度センサ３からの加速度データと、表面形状センサ４からの形状データと、ラインスキャンカメラ６からのスキャンデータと、ＧＰＳ受信機７からのＧＰＳ信号と、距離センサ５からの速度データ及び距離データと、マイクロフォン９からの音データと、わだち掘れ測定器１０からのわだち掘れ量データを、取得時刻に対応付けて記憶装置８３に格納する。ＣＰＵ８１は、加速度データが基準値を超えると、動画データから橋梁番号を抽出し、橋梁番号で特定される継手７の設置位置を加速度データの測定位置に対応付ける。ノートＰＣ８のディスプレイに、道路の検査を行うための検査画面を表示する。【選択図】図１
