Abstract
In this study, we focused on possibility of long-distant evacuation by railways in case of flooding of the Arakawa River in Tokyo. We developed an evacuation simulation system to analyze it. As result, we found that the evacuation has high difficulty. As the reasons we can point out that the transportation capacity for railways is relatively small for amount of evacuees and that the tens thousands of evacuee waiting for a train appears in or near a station and it cannot be uncontrollable. We have to grasp the capacity of other transportations such bus and walk and possibility of stay in a building, and find the feasible evacuation plan with combination of various transportations.
