Abstract
In an advanced-cruise-assist highway system, an AHS center facility, which is an upper facility for on-road facilities, periodically receives diagnostic information from the on-road facilities, and when it is determined that any on-road facility is in the faulty state, communicates the information that the on-road facility is in the faulty state to on-road facilities upstream from the faulty on-road facility, and the on-road facilities having received the information on the fault in the downstream on-road facility communicates the information that the downstream on-road facility is in the faulty state via a road-to-vehicle communication facility to AHS vehicles having the possibility of entering a zone under control by the faulty on-road facility. Further the information that the downstream on-road facility is in the faulty state is displayed on information board which can be recognize by vehicles having the possibility of entering a zone under control by the faulty on-road facility.
