摘要:
在城市轨道交通物理拓扑层、设施能力层与客流分布层网络模型基础上，构建了多属性网络。阐述了网络拥堵易发点的网络拓扑、网络运输能力及网络客流等特征指标，并采用基于AHP熵权法的组合权重法对拥堵易发点进行拥堵风险的辨识和评估，探究了网络拓扑结构、运输能力和客流需求之间的关联性。在北京轨道交通的实例中，识别的拥堵易发点多为衔接郊区线与市区线的换乘站。这验证了识别和评价方法的有效性和实用性。
Abstracts:
Based on the network model of physical topology layer, facility capability layer and passenger flow distribution layer of urban rail transit, a multi-attribute network is constructed. The feature indicators of network congestion-prone points, such as network topology, network transportation capacity, and network passenger flow are expounded, and combination weight method based on AHP-entropy weight method is adopted to identify and evaluate the congestion risk of congestion-prone points, and to explore correlation among network topology structure, transportation capacity and passenger flow demand. In the case of Beijing Rail Transit, most of the identified congestion-prone points are the transfer stations that connect suburban line and urban line. This verifies the validity and practicability of the identification and evaluation method.
