Development of Tsunami Evacuation Simulation System for Disaster Prevention Plan in Urban Space

At present, hazard maps are developed using computationally expensive techniques. After a major disaster, these maps must be revised. We developed a tsunami evacuation simulation system using a game engine and open data at low cost. An agent that performs evacuation actions, and autonomously searches for evacuation destinations and evacuation behaviors at specified speeds was developed, to clarify current issues with the location of evacuation sites. The agent prepared three types of walking speeds and disaster conditions, and two types of evacuation behaviors, and could freely change the number and ratio of agents. As a result of the simulation, it became clear that there are places where victims are concentrated even in inland areas.
