Social force model is a classic model in crowd movement simulation.The model expresses the subjective wishes of pedestrians and the interaction between pedestrians in the form of "force".The model is concise and easy to explain.However, there are many factors that affect pedestrian movement, and the calculation of self-driving force and social psychological force in the primitive social force model is insufficient.In order to enable the model to simulate the real movement process, many researchers have improved the social force model.This paper mainly studies the subject in the process of crowd evacuation, pedestrians.Pedestrians are modeled from two aspects: pedestrian characteristics and pedestrian roles.The characteristics of pedestrians include the social relationship between pedestrians, the personality of pedestrians and individual emotions.The degree of interference between pedestrians with different levels of intimacy is different, and pedestrian emotions will also affect the judgment of pedes-trians.
