A restricted area ( 60 ) is created based on positional information of a manned vehicle ( 20 ) traveling one of outward/return lanes ( 51, 52 ), and a detour course ( 72 ) is created based on information of the restricted area ( 60 ). Information on the detour course ( 72 ) is provided to the unmanned vehicles ( 10, 11 ) and the manned vehicle ( 20 ). Based on the positional information of the unmanned vehicles ( 10, 11 ) which proceed towards each other from the opposite directions with the restricted area ( 60 ) therebetween, the unmanned vehicle ( 11 ) on the lane ( 52 ) which is the opposite side of the restricted area ( 60 ) is blocked at a block position ( 61 B) and at the same time a travel permission command for permitting traveling the detour course ( 72 ) is issued to the unmanned vehicle ( 10 ) traveling the lane ( 51 ) on the restricted area side so that the unmanned vehicle ( 10 ) travels the detour course ( 72 ).
