In the Hyogoken Nanbu Earthquake occurred at Jan. 17, 1995，rhere is a fact that various rescue operations in the first stage can not be performed effectively because direct damage information caused by the earthquake can not gather. After the Hyogoken Nanbu Earthquake, research on real time disaster prevention systems are performed in order to plan effective disaster prevention system and perform effetive rescue operations just after a large earthquake in the future. In this paper, a simulation system on rescue is developed and proposed. This system can predict earthquake disaster spatially and temporally by using intelligent systems such as cellular automata and multi－agent system. Proposed system is developed aiming to gather various information in real time when earthquake disasters are occurred and to support rescue operation smoothy. In this system, rescue operations in earthquake disasters are simulated by using proposed system and the ability of disaster prevention is discussed and clarified. In addition, RFID (Radio Frrquencv Identification) is introduced as a brand-new technique in various fields. RFID is considered to be a handy information gathering device and in great disasters, informlation on constructions such as structural members, construction materials and information of peoples who have RFID cards can be gathered by sending the radio waves. In this paper, applicability of RFID is also proposed and discussed. The proposed system consists of two parts. In the first part, predictions of direct damages from an earthquake are performed by using empirical equations. Here, judgment whether buildings are collapsed, the ratio that people are trapped in the wreckage and so on are estimated. The virtual city model is defined as a two-dimensional plane which is divided into cells. In the second part, rescue activities are simulated in accordance with direct damages predicted in the first part. Here, the transition of the earthquake human disaster in the urban area by rescue operation can be simulated in consideration with the change in a time disaster situation. In this system, rescue operations are assumed to be performed by the family of trapped persons and rescue teams． Persons and rescue teams are assumed as agents and can act autonomously based on their own rules. As for a target city. Takarazuka City, a middle city in Hyogo Prefecture, Japan is employed and is mapped as digital data to lOm mesh. Three case studies are carried out. It becomes possible to compare human damages for time and the effective acceleration on the ground became possible by proposed system. The transition processes of human damage are obtained and discussed spatially and timewise. Results of digital simulations shows effectiveness of rescue operations by rescue teams are clarified and the layout planning of fire departments are also discussed. It is proved that that proposed system is effetive for rescue simulations and the estimation of disaster prevention power prior to large earthquake disasters in the future. Furthermore, applicability of RFID to real time disaster prevention system is also discussed. To perform more effective and realistic simulations, it is necessary to perform further improvements of proposed system.
