摘要
信号交叉口作为城市道路的重要组成部分,其饱和流率受众多因素的影响。以美国通行能力手册中饱和流率模型为基础,通过对北京市典型信号交叉口车头时距的现场测定,对设计时速与直行车道数对饱和流率的影响进行研究,可完善饱和流率修正模型。
As the important component of the urban road, saturation flow rate at signalized intersection is influenced by many factors. Based on the model of saturation flow rate in HCM, cowl time-interval at typical signalized intersection in Beijing is measured on field, at the same time the design speed and the number of through lanes are analyzed about the influence. All these would improve the adjustment model of saturation flow rate.
