ABSTRACT

This research investigates how saturation flow is affected by bus stops and analyses whether the standard equation used in the UK is adequate for estimating the saturation flow of an approach, especially in the presence of a downstream-side bus stop. As part of the study, we undertook a survey of saturation flows at several junctions in the city of Leeds in England and seek to explain the factors affecting them, taking into account the bus stop located nearby. We develop bootstrapping regression models to explain the difference between the observed and estimated saturation flows and propose an extension to the standard model, accounting for the bus stop located nearby. Finally, this paper illustrates the methods developed and reports on how performance can be improved by reconfiguring a junction.

摘要

这项研究调查了公交车站对饱和流量的影响，并分析了英国使用的标准方程是否足以估计方法的饱和流量，尤其是在存在下游公交车站的情况下。作为研究的一部分，我们对英格兰利兹市的几个路口的饱和流进行了调查，并考虑到附近的公交车站，试图解释影响它们的因素。我们开发了引导回归模型来解释观察到的和估计的饱和流之间的差异，并提出对标准模型的扩展，考虑到位于附近的公交车站。最后，本文说明了开发的方法并报告了如何通过重新配置连接来提高性能。
