To inexpensively and efficiently detect a deterioration degree of a road surface.SOLUTION: A road surface monitoring system 100 includes: a vehicle information acquisition section 31 for acquiring vehicle information corresponding to a road surface state when the vehicle travels on a road from the vehicle; and a deterioration degree calculation section 32 for calculating a deterioration degree of the road based on the vehicle information. The vehicle information is the information detected without measuring a distance from the vehicle to the road surface of the road in the vehicle. The vehicle information acquisition section 31 acquires the vehicle information based on acceleration information detected by an acceleration sensor incorporated in the vehicle or a head unit 10 being an information unit arranged in the vehicle.SELECTED DRAWING: Figure 2

    【課題】路面の劣化度合を低コストで効率的に検出する。【解決手段】路面監視システム100は、車両が道路を走行したときの路面状態に応じた車両情報を車両から取得する車両情報取得部31と、車両情報に基づいて道路の劣化度合を算出する劣化度合算出部32とを備える。車両情報は、車両において車両から道路の路面までの距離を計測せずに検出された情報である。車両情報取得部31は、車両または車両に設置された情報機器であるヘッドユニット10に内蔵された加速度センサにより検出された加速度情報に基づいて、車両情報を取得する。【選択図】図2
