Abstract
In this paper, we built "Evacuation Simulation in Metropolitan Area" for the Tokyo Metropolitan Area. The simulation can evaluate policies for stranded commuters and provide several risk maps of heavy traffic in catastrophic disaster, using decision making model and movement data in the Tokyo Metropolitan Area on the Great East-Japan Earthquake. As a result, if catastrophic disaster occurs and everyone goes home all together in metropolitan area, we calculated that heavy traffic will overload the trunk lines for many hours in wide area and huge people(for example, six people in a square meter) along some sidewalks.
