To efficiently evaluate a road surface profile of a road.SOLUTION: A road surface evaluation device comprises: an information acquisition unit 111 which acquires travel information of a plurality of vehicles including position information of the plurality of traveling vehicles and acceleration information indicating acceleration of the plurality of vehicles, and acquires map information including information on a road; a road surface roughness evaluation unit 112 which evaluates the roughness of a road surface of the road based on the acceleration information of the plurality of vehicles acquired within a predetermined period by the information acquisition unit 111 and, when an integration degree of the acceleration information of the plurality of vehicles acquired within the predetermined period is less than a predetermined value, evaluates the roughness of the road by complementing the acceleration information of the plurality of vehicles acquired in the past prior to the predetermined period; and an output unit 113 which outputs roughness information of the road surface evaluated by the road surface roughness evaluation unit 112 by associating it with the information on the road acquired by the information acquisition unit 111.SELECTED DRAWING: Figure 3
【課題】道路の路面プロファイルを効率的に評価する。【解決手段】走行中の複数の車両の位置情報と複数の車両の加速度を示す加速度情報とを含む複数の車両のそれぞれの走行情報を取得するとともに、道路の情報を含む地図情報を取得する情報取得部111と、情報取得部111により所定期間内に取得された複数の車両の加速度情報に基づいて道路の路面の粗さを評価するとともに、所定期間内に取得された複数の車両の加速度情報の集積度が所定値未満であるとき、所定期間より過去に取得された複数の車両の加速度情報を補完して道路の粗さを評価する路面粗さ評価部112と、路面粗さ評価部112により評価された路面の粗さ情報を、情報取得部111により取得された道路の情報に対応付けて出力する出力部113と、を備える。【選択図】図3
