摘　　要：换乘效率是对轨道枢纽换乘功能的综合度量 ,对其评价能够发现轨道枢纽在运行过程中存在的问题并能找出解决问题的有效途径。通过对多指标综合评价问题均一评价方法的局限性分析 ,提出了用数据包络分析方法进行轨道枢纽换乘效率评价的新思路 ,建立了输入输出指标体系和DEA非均一评价模型 ,给出了换乘效率、输入冗余率和输出亏空率以及运行有效性的评价分析方法 ,并进行了广州地铁枢纽换乘效率评价的实例研究。结果表明利用Transfer efficiency is the synthetically estimating index of mass transit hub transfer functions, and transfer efficiency evaluation can help us to found out its operational problems and their solving approaches. Based on the limitation analysis of the uniform evaluation method for multiple indices comprehensive evaluation, a new idea is advanced about the evaluation of mass transit hub transfer efficiency in the theory of data envelopment analysis(DEA). The import export indexes and the DEA non uniform evaluation model are established. Also the method used to analyze the transfer efficiency, import redundant and export deficit ratio, and operational effectiveness is put forward. Finally the case study of the transfer efficiency evaluation of Guangzhou subway hubs is given. The results show that the established DEA method is more available for the evaluation of mass transit hub transfer efficiency than traditional models.
