Abstract: Based on the observation of pedestrian movement and pedestrian behavior, this paper combines with the social force model, and considers the pedestrian movement as a self-driven individual moving process in the continuous space. In order to solve the shortcomings of the interaction force between pedestrians, this paper introduces pedestrian field of perception and proposes a solution to pedestrian collision avoidance mechanism, which can efficiently solve the collision between human behaviors, and avoid the emergence of large area of human clogging. Simulation experiments show that the improved model can represent the basic flow diagram in the normal conditions, and have a good reproduction of lane forming in pedestrian flow.
