Variable Message Sign(VMS) increasing deployment as part of the ITS policy measures to provide information to road users in the area, but is not installed, the VMS status is insufficient. In this paper, in areas without such a VMS road users to road conditions and traffic information to provide Portable Variable Message Sign(PVMS) proposed. Existing VMS Unlike PVMS, Moving and Storage system configuration, operating plans, etc., should be available, so existing VMS and has the distinction of In order to operate efficiently compatible with all the power of a multi-phase transition to the proposed solar power and battery power, power systems, considering them and express terms according to the operation time to go is proposed. Is expected to be applicable based on the results of this study future battery used in a variety of portable display systems, as well as a PVMS
