Simulation model of pedestrian interactive behavior

This paper presents a simulation model for pedestrian collective behavior. It is supposed that the pedestrians make individual decisions during movement according to their wishes and interaction with other pedestrians. The follow effect, deterrent effect and rejection effect are put forth as latent interactive effects influencing pedestrian decisions. Three categories of potential fields were defined to model the pedestrian behavior by simulating pedestrians' decision processes. A circumstance potential field was defined to simulate the desire to targets. Moving and waiting potential fields were defined to model the interaction. Experiments were run for the model validation and coefficient performance verification. Performances and relationships of sensitivity coefficient, decay coefficient and diffusion coefficient are studied to clarify the effectiveness and flexibility of the presented model in generating pedestrian movement under a variety of situations. The simulation results show the good performance of the model in reflecting pedestrian interactive behavior.
