PROBLEM TO BE SOLVED: To improve boarding chassis parking management in a ferry. SOLUTION: A wireless IC address tag 11 is provided for sending the address of a chassis parking place 5a in the ferry 5 via an on-vehicle antenna 9 provided on a tractor head 2a to a wireless IC document tag 7 set on the tractor head 2a, when the tractor head 2a tows a chassis 2b and parks the chassis 2b at a chassis parking place 5a in the ferry 5. Thus, a work to enter the parking address in a boarding chassis parking slip by each driver can be eliminated and efficiency of parking management of a boarding chassis can be improved.
