1 CBR 1,024 Support of Specification and Preparation of Evacuation Planning with Evacuation Simulator Tomohisa Yamashita, 1 Shunsuke Soeda, 1 Masaki Onishi 1 and Noda Itsuki As described in this paper, we developed an evacuation planning assistance system for use before CBR attacks. With multiple regression analysis, we propose an analysis method for quantitative comparison of the effect of coping behaviors from the point of view of decrease in the damage. To calculate the damage quickly, our evacuation simulator with the one-dimensional pedestrian model was applied with systems designed to predict hazards of indoor gas diffusion. Our one-dimensional pedestrian model is designed to conduct simulations much faster, taking less than few minutes for simulation with ten thousands of evacuators. With our evacuation planning assist system, we investigated a simulated chemical attack on a major rail station. In our simulation, we showed a relation between the time necessary to begin coping behaviors of the managers and the damage to passengers.
