Analysis of the safety and reliability of the Moscow metropolitan

Introduction. The role of the Moscow metropolitan as the leading flagship of the entire transport infrastructure of the capital has increased. For the effective functioning of the metropolitan , it is important to comply with technical and regulatory indicators that determine the intensity of train traffic and affect the safety of the entire infrastructure. Aim. To analyze and evaluate the safety and reliability indicators of Moscow metropolitan facilities in order to improve the efficiency of its functioning. Materials and Methods. Statistical modeling methods, methods of queuing theory, reliability theory, systems analysis and a structural-functional approach. Results. Quantitative characteristics of metro passenger flow are calculated, and the features of the occurrence of failures are determined. It is shown that due to the increase in passenger flow during rush hours, most stations operate at the limit of their capacity. An integral coefficient of metro capacity is proposed. Conclusion. Active modernization of the Moscow metropolitan and the introduction of innovations contribute to increasing the reliability and comfort of passenger transportation. In order to improve the efficiency of the metro system, it is necessary to equip 100 % of all lines with innovative trains, and it is also important to begin the reconstruction of “problem” distances and implement a number of preventive measures. Innovative modernization of the metro will also increase the investment attractiveness of certain districts of Moscow.
