Abstract

An emergency information offering system collects and offers information of lifeline facilities upon emergency properly by combining information infra-structures and public infrastructures. In the system, a center monitoring apparatus detects abnormality on the basis of information of the lifeline facilities collected by distributed monitoring apparatuses and meter apparatuses. A risk management apparatus grasps abnormal states and determines countermeasures of abnormality in accordance with the detected abnormality to produce the determined information. A guidance information management apparatus automatically prepares guidance information on the basis of the information and transmits the guidance information to a customer in response to an inquiry. When the guidance information management apparatus detects the congestion of lines, the guidance information management apparatus transmits the guidance information to telephone offices in respective areas, so that a guidance information offering apparatus installed in each office offers the information dispersedly. Thus, common customers can obtain the information relative to the lifeline facilities easily and the information upon emergency can be offered promptly. The congestion of lines due to an excessive amount of inquiries can be avoided.
