Leveling operation can be effectively performed at a discharge site without increasing a cost of vehicles, and a running course can be easily generated in a short time and at a low-cost. Based on each of measured position data of a survey line 20 of a discharge site 21, a normal line Lc normal to the survey line 20 is obtained, a target discharge position 26′ is positioned at a prescribed distance away from the survey line 20 in an inward direction of the discharge site 21 based on the normal line Lc, and then data of a running course 27 in which a reference approach direction 31 to approach the target discharge position 26′ is a direction normal to the survey line 20 are generated.
