According to a report of the Central Disaster Management Council, if a large flood in Tokyo area happens, approximately 663 thousand people are exposure to water, and 421 thousand people need to evacuate. Under this assumption, evacuation plan for mass people is required. In order to develop effective evacuation plans, planner needs a method to analysis of the evacuation risks, and also needs a method to evaluate alternative plans. However, for analysing large-scale flooding evacuation plans, because it requires to handle huge amounts of data is difficult to apply existing methods. In this study, we propose a method to evaluate evacuation plans for large flood in metropolitan area by using equilibrium analysis.
