摘　　要：评价轨道交通换乘枢纽的布局优劣、运营状况、服务水平,进而优化规划方案,给出5项评价指标,运用基于粗糙集理论的权系数确定方法,建立关系数据模型,通过计算灰色聚类分析模型的权系数的方法对轨道交通换乘枢纽进行评价,并结合实例说明方法的可行性。In order to evaluate the layout, operation and service level of mass transit transfer hub and to optimize planning schemes, the essay presents five evaluation indices. The relation data model is established by using the method of determining weighting coefficient based on rough set theory. Through calculating the weighting coefficient of the gray clustering model, the essay evaluates the mass transit transfer hub, and explains the feasibility of this method with actual cases.
