摘　　要：为了有效地保证车辆通过高速公路隧道群的安全性和舒适性,将实际路网输入Vissim仿真软件,对隧道群进行合理分段,结合亿车公里道路交通事故率和平均延误时间求取隧道群各路段的最佳限速值;通过深入分析隧道群交通流环境特征和影响因素,构建基于元胞自动机的隧道群交通流基本模型,为高速公路隧道群出现特殊情况,如隧道施工、事故、恶劣天气等应急条件下隧道群交通流特性的研究奠定基础。In order to guarantee the safety and comfort of vehicles passing through the highway tunnel cluster, practical road network data were imported into Vissim, a simulation software, to get tunnel cluster reasonably partitioned. Considering the road traffic accident rate and average delay, optimum speed limit was acquired. A basic model of traffic flow of highway tunnel cluster was established based on cellular automaton after thorough analysis of environmental characteristics and influencing factors, which lays the foundation for the study of traffic flow of highway tunnel cluster in emergencies.
