摘　　要：为深入研究公交专用道的不同设置方式对信号控制交叉口通行能力的影响,本文首先分析了公交专用道的不同设置方式对信号交叉口通行能力产生的影响,并以饱和流率计算模型为基础提出假设模型。其次通过利用VISSIM仿真得到各专用道交叉口在不同影响因素下的通行能力样本,再利用MATLAB软件对各影响因素所产生的通行能力折减系数进行拟合。最后利用层次分析法确定各影响因素的权重,从而确定各公交专用道的不同设置方式下信号控制交叉口通行能力的修正模型。该模型可为信号控制交叉口处公交专用道的设置条件和选择设置方式提供理论依据。To study the influence of the signalized intersection traffic capacity caused by the set-up ways of bus-only lane, the set-up ways was analyzed first, and a hypothetical models was put forward based on the saturated flow rate model. Then, the intersection capacity samples of each model were collected by VISSIM software simulation, and the reduction factors resulted by different influence factors with MATLAB. Finally, the weights of the reduction factors was determined with the analytic hierarchy process（in order to determine the modified models of the signalized intersection capacity for different situations）. The modified models can provide a theoretical basis for the bus-only lane＇s setting condition and rational decision-making at a signalized intersection.
