基于突变模型的轨道换乘效率评价

Rail Transfer Efficiency Evaluation Based on Catastrophe Model

在城市轨道交通系统中,枢纽站的换乘效率直接影响到线网整体的运行效能。根据指标选取原则和换乘效率影响因素,选取换乘通畅性、舒适性、组织人数、有效性作为评价指标,在突变级数法的基础上,推导出突变理论的基本模型和分歧方程,确定突变模型。以重庆市轨道交通两路口站为例,结合换乘站乘客满意度调查结果,利用突变模型对换乘效率进行评价。验证模型的实用性和可操作性,并进一步提出提升换乘效率的改进措施。所建立的效率评价模型可以为轨道换乘站的运营、组织及管理提供决策支持。

Among the urban rail transit system, hub transfer efficiency directly affects the overall operation performances of the rail network. In this paper, according to the index selection principle and the factors influencing the transfer efficiency, the transfer convenience, the amenity, the passenger number under organization, and the validity are selected as the evaluation inde- xes. On the basis of the mutation progression method, the basic model and divergence equations are derived, and the catastro- phe model is determined. Taking Lianglukou station in Chongqing as an example, combining with the passenger satisfaction sur- vey results of the transfer stations, this paper evaluates the transfer efficiency with the mutation model. Practicability and opera- bility of the model are verified, and improvement measures that may promote the transfer efficiency are then put forward. The efficiency evaluation model built in this paper may provide decision support for the operation, organization and management of the rail transit transfer station.
