STUDY ON THE TOILET AND FOOD RISK OF WALK RETURNING HOME WHO AT THE TIME OF THE CAPITAL DIRECTLY UNDER EARTHQUAKE

Metropolitan area capital function is concentrated, it is repeated a large number of people move every day, supported by large-scale transportation system for the railway as a representative. As soon as largely dependent on people in rail transport is moving means has been disrupted by the earthquake disaster, etc., will return home forced the situation by walking. The present study is to clarify by simulation move distribution status of each elapsed time of coming home person and stranded commuters due to the concentration to walk from Tokyo the five central wards of Tokyo to Kanagawa Prefecture side of the daytime population, in return home support object along the road, building collapse, influence and a large amount of walk return home's due to spread of fire was to quantify the analysis and risk about the challenges caused. In particular, he took up the toilet and food issues that are expected to be serious problems at the time of the capital directly under earthquake. For each problem, we consider the fill rate and require stockpile such as the number from the results obtained from the simulation.
