Abstract:	In 1995, Kobe city in Japan faced a serious condition by the Great Hanshin-Awaji Earthquake. According to the Kobe City government office reports, the number of death were 4,571, injured were 14,678 and the number of refugees lived in the shelters as of January.18, 1995 were 222,127. Moreover about 120,000 structures collapsed (include fully and partially), approximately 1,000 structures burned out (include completely, half and partially) and the traffic network and port facilities were damaged severely. After the earthquake, some researchers pointed out that emergency response activity was not fully functioned. For example, most of the fire department in Japan (excluding Kobe City) dispatched the fire fighters to Kobe City. However the headquarters for disaster countermeasures of Kobe City could not control the information to take an effective action to manage the supporting fire fighters and dispatched them to the fires. Of course, Kobe City government office had the Disaster reduction program and the Emergency response program. However, if planning support system (PSS) could accurately forecast the damage of the earthquake, the Emergency response activity could operate well. Since nobody experience severe disasters, nobody could not imagine the possible damage. Then such disaster estimation by using PSS is needed for the simulation system to estimate the damage. In this paper, we focused on human behavior such as evacuees and victims to unable return home. We already construct the model which can estimate the time to return home of the victims when the railway network is partially out of order. These models are based on the actual activity of the human being (e.g. age, gender, physical condition and more). However these are time sliced data which was collected by postal mail survey. In order for us to forecast the evacuation activity and return home activity in precise, accurate data are necessary. According to the former research in Japan, location data error with in a tolerance was about 25m by using the GPS in urban area. On the other hand, PHS (Personal Handy-phone System) can identify the location for every user and it can estimate the location more precisely in urban area. This paper aims to collect the human activity data accurately and continuously. We propose the new concept model for planning support system to make the disaster reduction program by using the GPS and PHS phone.
