The Research of Emergency Evacuation under Poison Gas Diffusion in Large Stadiums

Major international sporting events are often subject to terrorist attacks. Wrong emergency responses will bring enormous casualties. More and more people begin to pay attention to the management of such emergencies. The impact of the evacuation from this poison gas microscopic media is one of important issues among them. According to the principles of the cellular automata model and the use of computer simulation technology, we did the research for the emergency evacuation of the incident when the people suffered chemical poison gas in large stadiums. By the simulation results we analyzed the impact of large stadiums in case of emergency evacuation inefficiency, and put forward some corresponding countermeasures based on these problems. It has certain guiding significance to improve evacuation efficiency, reduce the loss of casualties in the emergencies and improve our emergency management plans.
