Pedestrian walk is an important transport mode and necessary component of personal travel activity. Simulation is an effective tool for pedestrian walk research. However, ordinary traffic simulation models and software are developed only for mobile vehicular traffic and unsuitable for pedestrian walk analysis. According to the scale and fidelity description of pedestrian walk behavior, pedestrian models are classified into macroscopic model, mesoscopic model and microscopic model. The paper analyzed the principles and features of the some common models including lattice gas model, cellular automata model, social force model and magneto mechanical model. The simulation results were analyzed. Furthermore, how to establish pedestrian simulation model based on Legion, STEPS, SimWalk and AnyLogic was discussed. The features of the software mentioned above were compared. The study indicates that the pedestrian simulation models can be established efficiently by using these softwares.
