Abstract
A wheel tread roughness estimation device includes a driving information acquisition unit that obtains driving information of a railway vehicle; a vehicle information acquisition unit that obtains vehicle information of the railway vehicle in service; a wheel tread roughness computation unit that determines a set value on the basis of the driving information and the vehicle information and computes an up-to-date wheel tread roughness by adding the set value to a preceding wheel tread roughness indicating a previously computed roughness of a wheel tread; and an output unit that outputs the up-to-date wheel tread roughness computed by the wheel tread roughness computation unit as wheel tread roughness information.
