DEVELOPMENT OF EVACUATION ROUTE SELECTION METHOD DEPENDING ON THE LEVEL OF TSUNAMI

Abstract

 In this study, we conducted inundation calculation of multiple tsunami sources with tsunami simulation and constructed the database of tsunami arrival times considering uncertainty of tsunami sources and aimed to propose a method to search evacuation routes not encountering the tsunami. The tsunami risk on evacuation route calculated by tsunami database, and evacuation behavior to select evacuation route that does not encounter the tsunami was incorporated into multi agent simulation. As a result, the method of selecting a route that does not encounter the tsunami during the evacuation behavior was established by changing the moving direction to the direction of the shortest distance of another evacuation shelter when there is a possibility of encountering a tsunami during the evacuation behavior calculated from the degree of danger. The area was simulated by this method, and confirmed that the mortality rate was reduced.
