Refuge Simulation in Coast Area of Kamakura City from Tsunami Disaster

Coast area in Japan exposure to the menaces of Tsunami disaster, so public agencies have to develop the evacuation manuals immediately, however, many agendas are remained for crowd behavior during disasters. Therefore, several refuge simulations were carried out, and this paper discusses that the fundamental verification of the influence on the priorities between distance and height to the safety zones for crowd routing. The target area was replaced numerical network model and the evacuee routing was calculated Dijikstra\u27s algorithm. Furthermore, the evacuation area and buildings which publicized by Kamakura city are assumed as the safety zones in the evacuation simulation. In addition, the upland which over 10 meter\u27s above sea level and the road which access the outer zone of flood area are also assumed the safety zones. The analytical results show that the times required for evacuating of all case were similar
