摘    要:针对我国城市交通特点,在改进经典的高速道路网宏观交通流模型METANET的基础上,提出了面向控制的城市快速路网宏观动态交通模型。该交通模型能够更好地描述快速路出口匝道流出能力受限、快速路主线起始点车流以及快速路主线车速控制等现象。对上海高架快速路的实际交通流数据进行了仿真研究,结果表明该模型较好地反映了城市快速路交通流的动态演化特征,可以作为城市交通控制系统分析和设计的有力工具。

关 键 词:城市快速路  宏观交通流模型  网络交通  动态交通控制

Abstract:Based on the analysis of the characteristics of urban freeway traffic in China, this paper improved the widely used macroscopic freeway network traffic model METANET, and proposed a macroscopic traffic model for dynamic urban free- way network control. The proposed model can better describe constrained out-flow at off-ramps, traffic flow behavior at mainstream origins, and travel flow behavior under the influence of dynamic speed limits. Simulation investigation of the model using real-world urban freeway traffic data at Shanghai, China, showed the satisfactory capability of the proposed model to describe the dynamic evolution of the urban freeway traffic. The proposed model provides a good tool for traffic control system design and analysis.
Keywords:Urban Freeways   Macroscopic Traffic Flow Model   Network Traffic  Dynamic Traffic Control
