Abstract

Tsunami Evacuation Simulation with ArcGIS Network Analyst Tool
Track: Disaster and Emergency Management
Authors: RYU SAITO

Author developed the tsunami evacuation simulation to find shortest evacuation routes for the outside of inundation area using Dijkstra's optimization of Network Analyst. The simulation with a time step of 1 second calculates travelling path of several thousand agents, people or cars, on the real road network in coastal region. Positions of all agents dynamically are relocated along a recalculated path toward another safe area depending on tsunami run-up estimated by a tsunami simulation model.
