摘要
换乘站作为城市轨道交通网络化发展的重要节点,其设施布局的合理性直接影响到整个线网的运行效率。本文综合考虑了换乘站的功能与作用,从换乘站的顺畅性、运行效率、设施供给方面选取具有代表性的因素,建立了可定量评价轨道交通换成设施布局合理性的3层指标体系,利用层次分析法进行权重打分,并结合BP神经网络建立了换乘站设施布局合理性评价模型。作者以重庆轨道交通两路口换乘站为例,进行了设施布局合理性分析,针对评价结果,提出了合理的改进建议。
A transfer station is an important node of a network development of an urban rail transit system, whose rationality of the facility layout directly affects the efficiency of the whole network. Considering the function of a transfer station, an evaluation system about the facility layout rationality of a city rail transit transfer station was established with consideration of smooth, operational efficiency, facility supply factors. Then, a typical model for the rationality of the facility layout of the transfer station was established using the weight of each index determined by the analytic hierarchy process and combined with the BP neural network. Taking Chongqing rail transit as an example, the rationality of Liang-Lookout transfer station was analyzed, and some reasonable suggestions were given.
