城市轨道交通高架线适用性评价研究

Evaluation Study on the Applicability of Elevated Lines of Urban Rail Transit

提出城市轨道交通高架线适用性的概念,并将适用性划分5个等级。根据高架线的特点及影响因素,选取指标建立高架线适用性评价体系。针对指标间具有相互影响的特点,选用网络层次分析法,对所有因素进行指标关系的网络连接及建模,并结合实例,运用Super Decisions软件对此复杂网络矩阵计算确定权重,选用模糊综合评价方法,对定性的因素进行量化分析,确定各指标的权重等级,从而对城市轨道交通高架线适用性进行评价。

The concept of the applicability of elevated URT lines was put forward for the first time, and free levels of applicability have been classified as a result. The evaluation system for the applicability of elevated urban rail transit was built by selecting indexes. Due to the interaction among indices of the applicability evaluation for elevated URT lines, the paper adopted the weighting function which could be achieved by ANP. Incorporating case study, the calculation was performed by the software Super Decisions. With the application of fuzzy comprehensive evaluation, the proposed model offers a quantification analysis methodology to calculate the weight degree of indices to evaluate the applicability of elevated lines of urban rail transit.
