Abstract
The article deals with the issues of quality management, reliability and safety of transport technical systems of deep-laid metro stations, transport hubs and other transport infrastructure facilities using continuous passenger lifting machines. Using the methods and tools of risk management and reliability theory, an analysis of the risks associated with dangerous consequences for the health and life of passengers is carried out. The article considers the inconsistencies of the required functioning of mechanical and electrical systems of the escalator, the influence of the «human factor», and identifies weaknesses. The methodology for making a decision on the development of a project for risk processing based on expert methods is proposed. As an example, the jamming of the stairs of the escalator stair bed due to contamination of the stair's flooring is considered. Based on the results of the analysis, projects for cleaning the flooring of escalator steps are proposed, their analysis is carried out, and recommendations are developed for the implementation of the projects under consideration at metro stations.
