Dynamic Traffic Simulation for Accessing Road Network Reliability under Large-Scale Events:System Development and Case Studies

针对大型活动的交通特点,以动态交通仿真模型INTEGRATION为基础,以路网可靠性算法为核心,建立了一个面向大型活动下路网可靠性影响评价的动态交通仿真平台,描述了该仿真平台的主要功能模块:路网构建模块、交通需求模块、交通运行模块和可靠性分析模块,提出了路网可靠性评价指标和算法,为大型活动下的路网可靠性评价提供了一套有效的分析工具。最后选择首都体育馆演唱会开展了实际案例的分析。

A dynamic traffic simulation system for accessing the road network reliability under large-scale events was developed,by using the dynamic traffic simulation model INTEGRATION and road network reliability evaluation methodologies. First,the functional modules of the system were described,which included road network module,traffic demand generation module,traffic simulation module,and road network reliability evaluation module. Then,the road network reliability evaluation systems and algorithms were developed. Therefore,it provided a set of effective analysis tool for evaluating the road network reliability under large-scale events. Finally,a real vocal concert in Beijing Capital Gym was selected as the case study.
