Abstract

Traffic-related analyses are essential to implementing traffic management approaches to create mobility more convenient. In this context, Passenger Car Unit (PCU) values as a uniform measure of vehicles are instrumental in analysis such as traffic capacity estimation, traffic flow model development, level of service determination, etc. These studies always demand a recently calculated set of PCU values since the traffic conditions in arterials often change. PCU values for expressway and three-lane (one-way) road types have not been calculated in the Sri Lankan context, and the available set of values has become somewhat outdated. Hence, this study used Chandra's method to assess the PCU values of ten vehicle categories for four different mid-block road sections in the Colombo district, Sri Lanka. The data relating to the two main variables of this method, categorical speed, and area of vehicles, were collected from field surveys. The results of four-lane arterials were aggregated and compared with the existing PCU values, intending to propose an updated set for general transportation studies in Sri Lanka.

斯里兰卡混合交通条件下不同中段路段的乘用车数量

交通相关的分析对于实施交通管理方法以创造更方便的流动性至关重要。在这种情况下，乘用车单元(PCU)值作为车辆的统一度量，在诸如交通容量估计、交通流模型开发、服务水平确定等分析中具有重要作用。这些研究总是需要最近计算的一组PCU值，因为交通条件在动脉经常变化。高速公路和三车道(单向)道路类型的PCU值没有在斯里兰卡的情况下计算，可用的值集已经有些过时了。因此，本研究使用钱德拉的方法来评估斯里兰卡科伦坡地区四个不同的中间街区路段的十种车辆类别的PCU值。与该方法的两个主要变量，分类速度和车辆面积有关的数据是从实地调查中收集的。汇总了四车道动脉的结果，并与现有的PCU值进行了比较，旨在为斯里兰卡的一般交通研究提出一个更新的集合。
