In this paper, we examine wide area evacuation plans that use public transportation. Regarding wide area evacuation plans vigorous efforts are being made by the national and local governments. However, in wide area evacuation, the issues are so large and intertwined that they tend to fall into a situation where it is difficult to know where to start. Because of this, the reality is that it is difficult to formulate a concrete and effective wide area evacuation plan. Based on this situation, this paper researches the wide area evacuation plan from the Tama River flood, assuming the use of public transportation in Setagaya Ward, for the purpose of contributing to future wide area evacuation plan considerations. This plan is not defined as a wide area evacuation plan because it does not evacuate to other municipalities across administrative boundaries and does not require coordination with neighboring municipalities. The area subject to the plan is located on the left bank of the Tama River, one of the two major rivers in Tokyo, and as the entire area will be flooded, it will be necessary to evacuate to a wider area. In addition, the evacuation target population exceeds 50,000 people, and the plan to evacuate to evacuation shelters in the event of floods located over a wide area in the ward is a plan with a scale and content comparable to wide area evacuation. In many cases, wide area evacuation plans have not yet reached the stage of concrete formulation, so research that specifically analyzes and evaluates the content of wide area evacuation plans has not progressed. In such a situation, this research aims to analyze and evaluate the ward's flood evacuation plan, assuming infectious diseases epidemic.
