基于改进因子评点法的公交专用道服务水平分级

通过引入因子评点法及分析其原理，提出了改进的因子评点法，拓展了理论方法 的应用范围.提出以单位公交专用道延误作为评价公交专用道的服务水平分级的指标；针对 既有的上游停靠站延误估算模型，通过实际调研确定模型中解释变量的取值，从而获取容量 为15 288 的延误样本；然后基于延误样本对单位公交专用道延误进行频次分析，得到其累积 分布，采用改进的因子评点法对公交专用道服务水平进行分级.本文研究成果为公交专用道 的运营评价和规划设计提供了指导依据.

Level of Service Criteria of Bus Lane Based on Improved Factor Assessment Method

By introducing Factor Assessment Method and analyzing its principle, a new method called Improved Factor Assessment Method is proposed, and so utilization of theoretical method is enhanced. The measure of Unit Delay of Bus Lane is proposed and used as an indicator to evaluate bus lane level of service (LOS). An estimation model of bus delay at near- side stop developed in previous study is used to obtain delay sample. The values of explanatory variables in this model are identified through field surveys and based on which the delay sample of bus lane is obtained and its size is 15 288. Frequency analysis for Unit Delay of Bus Lane is conducted and so its cumulative distribution is obtained. Based on the cumulative distribution and using the Improved Factor Assessment Method LOS criteria of bus lanes in China are established. The LOS criteria established in this paper can provide guidance for operation, design and planning of bus lanes.
