Abstract
Every time the haulage vehicle position data and the road surface condition data are received from a haulage vehicle, the segment including a position specified by the haulage vehicle position data, a reception time, and the road surface condition data are associated with one another for accumulation. Every time the repair vehicle position data and the work status data indicating a working state are received from a repair vehicle, the road surface condition data associated with the segment including a position specified by the accumulated repair vehicle position data is reset. Every time the road surface condition data is newly accumulated, a prediction function is determined to predict a chronological change in road surface conditions of the segment based on the road surface condition data accumulated on a segment-by-segment basis and a repair scheduled time-of-day is calculated according to the prediction function to output to an output apparatus.
