摘　　要：针对接驳地铁的公交线路站台分配不合理现象以及由此引起的公交站台利用率不均衡、服务水平较低等问题,本文以乘客总换乘距离最短、公交排队进站总等待时间最小为目标,使用ε约束方法建立帕累托边界,利用权重系数反映不同决策者对两个目标的偏好,建立接驳地铁系统的公交线路布置优化模型.以北京地铁4号线西苑站接驳地铁的公交系统为例进行案例研究,验证模型有效性与实用性.结果表明:该模型可用于接驳地铁系统的公共交通站台线路布置优化,从而提高公共交通服务水平及公交车辆运行效率.Aiming at unreasonable distribution of feeder bus lines which leads to unbalanced utilization rate of bus stops and the low level of passenger service, an optimization model is established to obtain the shortest total passenger＇s transfer distance and the minimum the total time of all buses dwelling at bus stops. This paper gives Pareto frontiers by constraint approach and employs weight coefficients to indicate the preference of decision makers. Case studies of the Xiyuan Station in Belling are implemented to verify the validity and practicability. The results from case studies shows that the proposed model is capable of optimizing the layout of the feeder bus routes connecting subways at bus stops and improving the level of public transit service and the operational efficiency of buses.
