摘　　要：Pedestrian crowd in public buildings is usually a hidden trouble.The more serious the crowd,the higher the accident risk,and the heavier the casualties and loss may be.Based on the social force model,this paper puts forward an improved model which takes into account the anisotropic charac-teristic of pedestrian movement and the avoidance of dynamic congested areas.Furthermore,the al-gorithm has been optimized with the help of static force grid,so the simulation becomes more veritable and computational speed is also greatly accelerated.The improved model is also applied to research on the characters of pedestrian crowd,and the conclusion can provide a basis for the risk assessment of pedestrian crowd and the design of public buildings.Pedestrian crowd in public buildings is usually a hidden trouble. The more serious the crowd, the higher the accident risk, and the heavier the casualties and loss may be. Based on the social force model, this paper puts forward an improved model which takes into account the anisotropic characteristic of pedestrian movement and the avoidance of dynamic congested areas. Furthermore, the algorithm has been optimized with the help of static force grid, so the simulation becomes more veritable and computational speed is also greatly accelerated. The improved model is also applied to research on the characters of pedestrian crowd, and the conclusion can provide a basis for the risk assessment of pedestrian crowd and the design of public buildings.
