During and after any extreme event of natural or man-made origin, the primary objectives are getting people out of harms way and to an safety area. The keys to saving lives are orderly and efficient evacuations. We have proposed a new model based on the traditional lattice gas automate, in our paper, it can simulate the human crowd behavior in the crowd facilities, such as shopping malls, stadiums, school buildings etc, under the condition that many people rush to exits at the same time. In this model, people move by their instinct and the information what they obtained. In order to reappearance the scenes of the events and reach a better evacuation. We introduce psychological factors, velocity levels of pedestrians and exit levels in our model.
