【摘要】 通过分析北京、上海、广州等城市采集的大量快速路的实测数据,应用数理统计的方法建立了速度和流量的统计回归模型,结合标定的Greenshields模型,给出了我国城市快速路基本路段的理想通行能力值和不同车道通行能力的修正系数．为我国快速路的规划设计、运行分析以及为城市道路相关规范的修订提供参考．更多还原

【Abstract】 Based on the field data collected from Beijing,Shanghai and Guangzhou city,this study applied re- gression analysis method to build speed-flow relationship model and furthermore calibrated Greenshields mod- el.Considering results of two aspects synthetically,the ideal capacity of expressway and correctional coeffi- cients of different lanes are recommended.Consequently this study can not only provide reference for the plan- ning,design and operation analysis of expressway,but also help to revise the interrelated code or criterion of urban streets.更多还原
