To provide a road property estimation device capable of easily estimating whether or not a road includes a rut, a gentle depression, or the like.SOLUTION: A road property estimation device 10 includes: for example, an acquisition unit 20 for acquiring actual travel information indicating a current travel state of a vehicle, position information indicating a current position of the vehicle, and weather information of an area in which the vehicle is present; a detection unit 22a for detecting presence or absence of a water pool of a road on which the vehicle travels based on comparison results between reference travel information indicating the travel state of the vehicle on a road surface where there is no water pool and the actual travel information and weather information; an estimation unit 22b for estimating road properties of the road where a water pool is formed based on a distribution mode of position information corresponding to the actual travel information when a water pool is detected on the road; and an output unit 22c for outputting property information including the road properties.SELECTED DRAWING: Figure 1

    【課題】轍や緩やかな凹み等を含んでいる道路か否かを容易に推定することができる道路性状推定装置を提供する。【解決手段】道路性状推定装置10は、例えば、車両の現在の走行状態を示す実走行情報と、車両の現在位置を示す位置情報と、車両が存在する領域の天候情報と、を取得する取得部20と、水溜まりが存在しない路面における車両の走行状態を示す基準走行情報と実走行情報との比較結果と天候情報とに基づき、車両が走行する道路の水溜まりの有無を検知する検知部22aと、道路に水溜まりが検知された場合の実走行情報に対応する位置情報の分布態様に基づき、水溜まりが形成される道路の道路性状を推定する推定部22bと、道路性状を含む性状情報を出力する出力部22cと、を備える。【選択図】図1
