| Abstract: | 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. |
