Development of a Tsunami Evacuation Behavior Simulation System with Massive Evacuation Agents

We present an evacuation behavior simulation system at the time of tsunami using the evacuation agent of a game engine. The tsunami evacuation behavior simulation system is a system that enables local governments and residents to work together to formulate disaster prevention plans. As a representation of a simple tsunami, in this system, a slightly oblique plane is inserted as the sea surface to a three-dimensional model of the terrain, building, and road, which is generated by geographical information system data. Mass agents of evacuees randomly placed on the road will move toward the nearest wide evacuation shelter or tsunami evacuation building. As a result, problems were found in the shape of some roads and the position of evacuation buildings.
