Abstract
To scientifically evaluate the congest level of pedestrian traffic network inside and outside gymnasiums during the termination of special events, the audiences′real-time traffic demand evaluation and walking route choice during evacuating gymnasium exits were investigated. Based on physical analy⁃sis and Stochastic Simulation, a traffic demand generation and distribution model for audiences′exiting gymnasiums was developed. On this basis, a dynamic pedestrian equilibrium assignment model based on route choice and a heuristic algorithm were proposed. The model proposed was applied to the termina⁃tion of games in large sport stadiums. The numerical results show that the model could capture the dy⁃namic traffic demand during exiting gymnasiums and the pedestrian traffic density of channel bottle⁃neck, describe the process that the audience volume increases rapidly to the peak and gradually decreas⁃es and the extended process that audiences evacuate the stadium exits with traffic capacity constraints, and analyze the pedestrian density on the walkway inside and outside of gymnasiums.关键词
