Crowd evacuation simulation is an important research issue for designing reasonable building layouts andplanning more effective evacuation routes. The social force model (SFM) is an important pedestrian movementmodel, and is widely used in crowd evacuation simulations. The model can effectively simulate crowdevacuation behaviors in a simple scene, but for a multi-obstacle scene, the model could result in someundesirable problems, such as pedestrian evacuation trajectory oscillation, pedestrian stagnation and poorevacuation routing. This paper analyzes the causes of these problems and proposes an improved SFM forcomplex multi-obstacle scenes. The new model adds navigation points and walking shortest route principles tothe SFM. Based on the proposed model, a crowd evacuation simulation system is developed, and the crowdevacuation simulation was carried out in various scenes, including some with simple obstacles, as well as thosewith multi-obstacles. Experiments show that the pedestrians in the proposed model can effectively bypassobstacles and plan reasonable evacuation routes.
