Pedestrian traffic system is a stochastic dynamic system with uncertainty cluster density, non-linear and the interaction among the individuals. Now computer dynamic simulation is one of the effective methods to study the mechanical characteristics of pedestrian flow in the public buildings. Aimed at the problems that under the same scene different software tools used in pedestrian simulation may lead to different results, the paper analyses the differences of the simulation software models in performance. Furthermore, it explains the reasons of the errors with discrete space resulting to the simulation. With comparing experimental data and simulation results of the travel time in the passageway of metro station, it shown that the performance of pedestrian traffic simulation is closely related to the building environment. The case results showed that the fidelity that multi-agent simulation model of continuous vector space for reproducing pedestrian behaviors in complex passageway can reach up to 87%.
