摘要
采用交通渠化后引起了城市道路部分路段(交叉口进口段)的交通流特性有别于普通路段,针对这种变化,采用1种以路段通行能力为等价标准来计算车辆折算系数的方法,并通过实例进行了验算。推荐交叉口进口段的大型车车辆折算系数为3.0。
The traffic characteristics of the roadway section next to channelized intersection are different from those of the common urban road. Based on the field data, the authors developed an approach to quantify heavy vehicles＇ effect by deriving PCE by using capacity as the equivalency criterion, and recommend the PCE factor at section next to urban intersection to be 3.0.
