To provide a system and method for automatically and stably associating inspection value data synchronous with angular speed data with track position data.
An angular speed sensor installed on a vehicle sequentially acquires angular speed data expressing a yaw angular speed in synchronization with inspection value data and stores the angular speed data together with the inspection value data time sequentially, a time-series set of angular speed data expressing yaw angular speeds, which satisfies a specified condition is extracted, the time-series set is matched as a detection curve with a curve in a curve alignment diagram of a track management diagram to acquire a start point or an end point of the matched detection curve, the start point or the end point of the detection curve are associated with a start point or an end point of the curve in the curve alignment diagram, and further associated with track position data of a track management diagram corresponding to the start point or the end point of the curve to thereby associate the angular speed data with the track position data of the track management diagram, and inspection value data synchronous with the angular speed data is associated with the track position data on the basis of the angular speed data associated with the track position data.
