奥运国家体育场车辆疏散方案及其实证分析

Case Analysis on Vehicle Parking and Departure Plans for the National Stadium

国家体育场作为北京奥运会的主会场成功地承担了开闭幕式和田径赛事任务.本文研究了其停车场车辆的交通疏散问题,制定了疏散方案.首先,分析了国家体育场停车场和泊位布局及车辆疏散的具体条件.其次,通过给定环境的场景和参数设定,对具体的奥运场馆停车场车辆的疏散方案进行了仿真和评价.最后,利用奥运会开幕式的车辆疏散实测数据进行了对比分析,在仿真中要员和贵宾车辆的总疏散时间为26 min,而奥运会开幕式车辆疏散实测结果表明,全部要员、贵宾疏散完毕,共用时27 min,从而验证了车辆疏散方案的准确性和实用性.

As the main venue of the 2008 Beijing Olympic Games, the National Stadium hosted the opening and closing ceremonies, field and track events, and final football games. This paper intends to study the problems associated with vehicle evacuation from the parking lot, and develop evacuation plans. First, the paper analyzes the particular conditions of the parking lot in the National Stadium, as well as its layout and vehicle evacuation. Then, it simulates and evaluates the evacuation plans with the suitably given parameters, based on the real blueprint of the National Stadium and scenarios. Finally, it conducts a comparative analysis on the accuracy and practicability of the vehicle evacuation plans based on the field data collected at the opening ceremony of the Olympic Games. The simulation result shows that the total vehicle evacuation time was 26 minutes and the real evacuation time was 27 minutes on the day of the opening ceremony, which verifies that the study is accurate and practical.
