Research on evacuation outside of the building using multi-agent simulation

Evacuation outside of the building is an important stage in urban emergency evacuation, the multi-agent simulative technique based on distributed environment can play an important part when analyzing the impact on individual behavior in traffic from simulating behaviors of traffic individuals in the emergency situation because of the existing dynamic, complicated and uncertain feature in the environment. In this article, the virtual traffic environment and traffic agents (evacuees and vehicles) are constructed and the basic simulation rules are setup up by StarLogo which is a simulation software based on multi-agent technique. The process of evacuation is divided into two stages in time, the phenomenon of evacuation and block are showed in the first stage in simulation and the sudden interference to streets close to threatened area from evacuees are evaluated by a figure about variety of traffic volume-time on these streets. The differences of evacuation time that evacuees needed when they get across different kinds of evacuation room are evaluated by simulation in given condition. The results from simulation should be the conferences used by decision makers when they choose optimal evacuation way.
