摘要
基于多天的快速路检测器实测数据,在利用平均车长进行占有率及密度转化后,采用Van-Aerde单一结构模型标定了北京市三环快速路典型路段的不同天、内外环及不同车道的交通流参数,进行了多维度的交通流特性对比分析,为北京城市快速路系统的运营管理及规划设计提供理论基础和数据支持.
Based on the multi-days field data from the detectors on the expressways,after transforms detected occupancies to densities using the average vehicle length,this paper calibrates the basic traffic flow parameters on the typical sections of the 3rd expressways for different days,inner and outer ring-road sections,as well as each lane of the expressways using Van-Aerde single-regime model,and subsequently provides a multidimensional comparative analysis to the traffic flow characteristics.The conclusions from this research will provide a theoretical foundation and data support to the operations,managements,planning and the design of expressways in Beijing.
