信号交叉口公交车辆换算系数研究

Passenger Car Equivalent for Bus at Signalized Intersection

根据现有规范和北京市信号交叉口车辆运行实际情况对公交车辆的车型进行划分,建立求解车辆换算系数的理论模型。根据对北京市60个信号交叉口的实际调查,确定交叉口进口道标准车的饱和车头时距,给出两类公交车辆换算系数的推荐值,可供同行参考。

According to existing criteria and the actual situation of the signalized intersections in Beijing,the buses are divide into two types,and then a model for calculating the Passenger Car Equivalents（PCE） is establish.Based on the survey of 60 signalized intersections in Beijing,the satur-ation headways of standard car on entrance lane at crossing is ascertained,and recommended PCE of two types of bus are proposed,which can provide reference for peers.
