Effective pedestrian organization plan and management is necessary for the crowded spectators in the complex venue and environment in special event. 2008 Beijing Olympic Games is a real big challenge to the staff in responsible for pedestrian management and related planning tasks. This paper introduces a simulation method of application on pedestrian facilities and management during the Beijing Olympic Games. According to the pedestrian characters in the Olympics, actual data are colleted for parameter calibration, and then simulation approach is introduced. The methodology and its application were illustrated through a case study on the National Stadium-the main stadium of the Beijing Olympic Games. Based on a comprehensive analysis of the pedestrian facilities and pedestrian management methods, different pedestrian egress plans were proposed and the optimal plan was identified through the simulation study. The actual pedestrian traffic operations during the Olympic Games proved the usefulness and effectiveness of the proposed methodology and egress plan.
