Tsunami Evacuation Simulation System for Disaster Prevention Plan

Hazard maps are currently developed using computationally expensive techniques and must be revised after a major disaster. Therefore, we developed a low-cost tsunami evacuation simulation system using a game engine and open data. A simulation evaluation was conducted using the target area of Kamakura City, Japan. We also developed an agent that performs evacuation actions and autonomously searches for evacuation destinations and evacuation behaviors at specified speeds in order to clarify current issues with the location of evacuation sites. The agent prepared three walking speeds, three disaster conditions, and two evacuation behaviors and could freely change the number and ratio of agents. The simulation results revealed locations with high concentrations of tsunami victims, even in inland areas.
