PROBLEM TO BE SOLVED: To solve problems, when a disaster has occurred or occurrence prediction is issued, wherein automobiles, etc. are involved in accidents and confusion is developed due to a delay in arrangement for road regulation performed by policepersons. SOLUTION: When information is issued, for example, at an earthquake analysis center 11 on the occurrence or prediction of an earthquake, it is transmitted to a detour retrieval server 15 of a traffic information center 14 to retrieve a hazardous area corresponding to the earthquake intensity in the area. Areas to be closed are determined and detours are determined by a detour determination part 24 to avoid driving in the hazardous area. Since information on the closed areas and information on the detours are transmitted to a moving automobile "A", hazards and confusion can be prevented from occurring and smooth driving is made possible.
