PROBLEM TO BE SOLVED: To reduce a workload of a user or the like and to improve work efficiency. A storage unit that stores a first reference line K1 and a second reference line K2, and a traveling route generation unit that generates parallel paths P1 and P2 parallel to the first reference line K1 or the second reference line K2. And an automatic travel control unit that automatically travels the work vehicle 1 along the parallel routes P1 and P2 generated by the travel route generation unit.
