Level of Service for Passage in Urban Rail Transit Station

The level of service determines the operational efficiency of the station. In order to accurately judge and predict the level of service of the passage, first of all, the evaluation index is set up. The satisfaction grading standard is established, The cloud model is used to describe the level of service based on fuzzy theory. The level of service of passage at a certain time is predicted based on Markov theory. Taking the facilities of Xizhimen station in Beijing Subway as an example, the level of passage service is evaluated and predicted, and the feasibility of the theory is verified.
