城市快速路基本路段车辆运行特性调查与分析

Investigation and Analysis of Vehicle Running Characteristics at Basic Stretch on High-Speed Road of City

快速路系统既承担大城市内部中长距离的机动车交通,又承担大城市与区域内其它城镇联系的对外交通。依托教育部高等学校博士学科点专项科研基金项目《城市快速路系统通行能力计算与服务水平评价方法研究》,对国内七个典型城市的快速路进行了交通调查,从交通量的变化特性、车速运行特性及交通组成特性方面对车辆运行特性进行了分析。

The high - speed road takes on both the motor vehicle＇ s traffic in the middle and long distances inside big city and the external traffic being in big city contact with other towns in area. On the basis of ＂Research on computations of Traffic Capacity of City High - Speed Road System and on Evaluations of Its Service Level＂ I- tem of Special Funds for Scientific Research on Doctor Subject in Colleges to Ministry of Education there has been carried out the traffic investigation of high - speed roads of seven typical cities at home. And the analysis of vehicle running characteristics was performed from properties of traffic volume changing, driving speed and traffic composition.
