Abstract
A haulage vehicle comprises: a position calculating system () calculating an estimated position of its own vehicle; a position range calculating unit () calculating a position range which is centered around the estimated position and in which the haulage vehicle is present with a predetermined expected probability; a maximum deviation amount calculating unit () calculating a maximum deviation amount indicating a highest value among the amounts of deviations between a target route of the haulage vehicle and each of points included in the position range; a target vehicle-speed decision unit () setting a target vehicle speed of the haulage vehicle to be relatively low when the maximum deviation amount is relatively large; and a target route-tracing unit () performing control for the haulage vehicle to travel along the target route in compliance with the target vehicle speed.
