Simulation of Emergency Evacuation of Pedestrians along the Road Networks in Nhatrang City

Evaluation and early warning for Tsunami disasters in coastal areas and islands need to research to save people and mitigate damages. This paper addresses the simulation of pedestrians evacuating along the road network in city. In a developing country, the coastal city often has a complicated roads network and the devices to support an evacuation are simple and shortage so the alert signs are the good devices. We assume that there is a given alert signs system in the city, pedestrians facing a Tsunami have difference behaviors with the signs. The simulations´s result help us to estimate the number of survivors and the global amount of rescue time. Agent based model is used to build the evacuation of pedestrians with details behaviors of them. The simulation of pedestrians evacuation in this article using the heterogeneous environment Geographic Information Systems(GIS) supporting realistic simulations. In addition, the simulation is applied for road networks in Nhatrang city.
