Simulation system of tsunami evacuation behavior during an earthquake around JR Osaka station area

Abstract

In the case of a Tonankai earthquake or Nankai earthquake occurring, it is predicted that tsunami damage will occur at the JR Osaka Station area. The purpose of this study is to propose a computer simulation which can calculate the appropriate behavior of evacuees in order to avoid tsunami damage in that situation. There are many institutions, department stores and hotels, and an underground shopping center, around JR Osaka Station. Therefore, various situations must be considered, such as collisions between people trying to evacuate to buildings and people trying to get away from the underground shopping center and buildings to the outside, in order to plan safe evacuation. In this paper, we implement a simulation that assumes various situations, and collect data fundamental to devising a method for inducing evacuation.
