Evacuation of pedestrians using lattice gas model and floor field model

This paper makes a study on the simulation on evacuation of pedestrians in a room with one exit and multi-obstacles, based on the lattice gas model and the floor field model. Use the probability of the floor field model to determine the main direction in movement of pedestrian. Then use the local motion rules of the lattice gas model to describe the behaviors of pedestrians. Pedestrians can bypass obstacles and leave away from the exit, making it accord with the actual circumstance of the evacuation under complicated environment. And evacuation time increase with the density of pedestrians monotonically.
