摘　　要：分析了城市快速路的运行特点,以通道控制的基本思路,提出快速路主路和辅路协调控制的方法。根据快速路交通流特性,建立主路和辅路路段的动态模型,进口和交叉口排队模型,根据不同的优化性能指标,确立了相应的优化策略和求解算法,为进一步开发实时控制算法打下基础。In this paper, the author analyzes the operation characteristics of urban expressway, presents the method of expressway and frontage coordinated control by the idea of freeway corridor control. According to traffic behaviors, the expressway dynamic traffic flow model and frontage traffic model, entry queue model and intersection queue model are used to describe traffic dynamics. By several different optimal per-formances criterion, corresponding optimization strategies and solution algorithm are determined to be the foundation of the further work to develop real time control algorithms.
