Abstract:

The pedestrian traffic system in public buildings is a nonlinear stochastic dynamic system with uncertain cluster density and interactive individuals. At present,computer dynamic simulation is one of the effective methods to investigate the dynamic characteristics of pedestrian traffic flow in public buildings. In this paper,aiming at the difference in simulation results of pedestrian evacuation obtained by several major simulation softwares in the same scene,the performance differences of the simulation software models are discussed,the simulation error due to the discrete space is analyzed,and the accuracy of the simulation models is evaluated by means of fidelity analysis. By comparing the simulated results of the travel time in the channels of the metro station with the experimental ones,it is found that the simulation performance of pedestrian traffic is closely related to the building environment,and that fidelity is important to the simulation model. Moreover,case study indicates that the multi-agent simulation model based on continuous vector space is of a fidelity up to 87% for reproducing the pedestrian behaviors in complex public buildings.
