高潮浸水を考慮した避難行動シミュレーションに基づく避難場所の評価に関する研究

It is necessary to examine the establishment of new evacuation spot so as to minimize the human toll of flooding occurred by a storm surge. Thus, to begin with, two types of evacuation simulations which reflect the result of a storm surge analysis are conducted; one is conducted under the current evacuation planning and the other is done under the combination plan of an additional evacuation spots and the current plan. Secondly, the effect of the additional evacuation spots and the amount of time required for an evacuation completion are seized, and the proper location of an evacuation spot and the reasonable evacuation route are discussed. The additional evacuation spot removes the jam of agents around the evacuation spot and encourage the quick escape from their house to the evacuation spots around which the flooding occurs. Thereby, the completion rate of evacuation under the combination plan increases by 20% compared to that under the current evacuation plan, and 90% of agents could finish evacuating in a final stage. Therefore, it is found that the additional evacuation spot with considering the flooding occurred by a storm surge has a major effect on an evacuation behavior.
