ROAD SURFACE ABNORMALITY DETECTION SYSTEM
To provide a road surface abnormality detection system that can detect a road surface abnormality according to differences in road surface abnormality repair determination criteria for each road manager.SOLUTION: A road surface abnormality detection system is configured to collect travel data including a detection result of an on-vehicle sensor 8 provided in a vehicle 5 from the vehicle 5 that travels on a road, identify an abnormality level suggesting presence of a road surface abnormality on a road surface of the road on which the vehicle 5 has travelled, based on the collected travel data, set an abnormality level threshold value for detecting a road surface abnormality based on a history of road maintenance for road abnormalities performed in the past, and detect that a road surface abnormality has occurred at a spot where the abnormality level identified on the road surface of the road on which the vehicle 5 has travelled exceeds the threshold value.SELECTED DRAWING: Figure 2
【課題】道路管理者毎の路面異常の補修の判断基準についての違いに対応して路面異常を検出することを可能にした路面異常検出システムを提供する。【解決手段】道路を走行する車両５から該車両５が備える車載センサ８の検出結果を含む走行データを収集し、収集した走行データに基づいて車両５の走行した道路の路面において路面異常の存在を示唆する異常度レベルを特定する一方で、過去に行われた路面異常に対する道路のメンテナンスの履歴に基づいて、路面異常を検出する異常度レベルの閾値を設定し、車両５の走行した道路の路面において特定された異常度レベルが閾値を上回る地点に対して路面異常が生じていることを検出するように構成する。【選択図】図２
