2008年北京奥运会期间，各比赛场馆需要对服务于贵宾、技术官员、运动员和注册媒体等奥林匹克大家庭成员的车辆进行有效地组织和管理。借鉴国外历届奥运会经验，北京奥组委主持开发了奥运车辆交通仿真模型，场馆交通运行模型作为其中一个模块，分析评价了奥运场馆交通运行方案的合理性，为北京奥运赛时交通规划提供了科学依据和决策支持。本文针对奥运场馆交通需求特点，提出场馆交通组织原则，介绍奥运场馆交通仿真分析方法，包括分析思路和步骤，交通需求分析和评价指标。最后以五棵松场馆群为分析实例，利用VISSIM仿真模型，测试了不同社会背景交通量条件和流线组织方案，从中推荐最优方案，并在奥运期间得到实际应用，运行效果证明了相关方案是可行的和有效的。

Traffic Organization with Simulation for Vehicles on Beijing Olympic Venues

During the Beijing Olympic Games,all venues needed to efficiently manage traffic circulations of Olympic Family members such as VIPs,technical officials,athletes,registered medium and so forth.Through developing traffic simulation models and performing simulation study for the Olympic venues,suitability and efficiencies of venue traffic operation plans were analyzed and evaluated.Travel demand characters of the Olympic venues were analyzed and traffic management principles were proposed.A methodology of conducting traffic simulation study was brought forward,as well as a case study of the Wukesong Indoor Stadium and Baseball Fields.Using VISSIM,different traffic operation plans under various non-Olympic background traffic volumes were tested and evaluated,and optimal plans were selected.Recommendations to improve the plans were also given based on study results.The actual traffic operations during the Games proved that the traffic operation plans and recommended improvements are applicable and effective.
