城轨路网下车站重要度的评价方法及应用

为了分析不同运营车站的重要程度,以此作为城市轨道交通运营管理的理论依据,通过对城市轨道交通典型运营车站的深入调研,分析影响车站重要度的因素,参照国家标准规范对各因素进行量化,从客流、车站属性和环境3方面构建了车站重要度评价指标体系。在分析各指标特性的基础之上,建立指标数据预处理方法,提出基于层次分析法的主成分分析综合评价模型,对车站的重要程度进行评价。最后选取北京城轨路网的8个典型车站进行实例验证,计算结果与实际情况吻合较好,该指标体系与评价模型能够在一定程度上为城市轨道交通运营管理提供理论决策支持。

Comprehensive evaluation and application of station importance in urban rail transit network

Under the network operation of urban rail transit, the station status is determined by many factors, such as the geographical location and the passengers, and its importance is different in the network. To analyze the importance as the theoretical basis for the operator, in-depth research was done and the various factors from the passenger, station property and environmental aspects were quantified according to the national standards, and the index system was built. Through the analysis of the indicator characteristics, the data preprocessing method was proposed. Then a comprehensive evaluation model was established based on the analytic hierarchy process(AHP) and principal component analysis to evaluate the importance. Finally, eight typical stations of Beijing rail network were selected to verify the model, and the calculation result agrees well with the actual situation. To some extent, the result can provide the theoretical decision support for urban rail transit operation management.
