Abstract
Coast area in Japan exposure to the menaces of tsunami disaster, so public agencies have to develop the refuge manuals immediately, however, many agendas are remained for crowd behavior during disasters. Therefore, several refuge simulations at the coast area in Kamakura city were carried out, and this paper discusses that the influence of the priorities between distance and height to the safety zones for crowd routing. The target area was replaced by numerical network model and the refuge routing was calculated by Dijikstra's algorithm. Furthermore, the refuge area and buildings which publicized by Kamakura city and the upland which over 10 meter's above sea level were assumed as the safety zones in the refuge simulation. The analytical results show that the difference of refuge routing and personal space are influenced on the number of refugee for each refuge area, but the time required for evacuating is similar through the same personal space simulations.
