The method of predictive calculations of the state of the rails as the main element of assessing the state of the track when planning major repairs of the track is given. With a standard service life of 600 to 700 million tons gross, it is necessary to predict the number of defective rails on the track when increasing the service life to 1100 million tons gross (considering local rail replacement during intermediate repairs). The polygon for assigning repairs is determined by the number of “Windows” that can be provided per week on the section. The projected increase in the work of the track causes the need to increase life cycle cost depreciation charges for the formation of the repair Fund for capital repairs by 30-35%.

“…Fuzzy logic is a powerful tool, used to solve complex problems, due to its ability to infer conclusions and produce answers based on vague, ambiguous, and/or qualitatively incomplete or inaccurate information [50,51]. As such, it is a useful tool for dealing with decisions in which the phenomenon is imprecise and vague [52].…”

Resilience is the ability of a system to adapt, persist, and transform as a reaction to threats, which may be external or internal to the system, while vulnerability is the state of being susceptible to harm from exposure to stresses associated with environmental and social change and from the inability to adapt. Based on a study of the threats that can affect urban mobility, we identified a gap regarding the analysis of the levels of resilience and vulnerability in the face of subsidy threats that can severely affect developing countries. This article measures the level of resilience and vulnerability due to the absence of public transport fare subsidies. For this purpose, we developed an approach based on fuzzy logic and applied it in 33 administrative regions (ARs) of the city of Rio de Janeiro, Brazil. We obtained four matrices of the levels of vulnerability and resilience of each of the regions as an origin and destination. The results show that areas nearest to the downtown region and those with high-capacity transportation available (commuter train and/or subway, systems with many transfer points) are more resilient, while a high level of vulnerability is associated with low income, negative socioeconomic indicators, and the predominance of road transportation to reach jobs. The contribution of this paper is the method applied to analyse the levels of vulnerability and resilience of public transport, which includes a threat that can cause a rupture that impacts routines and job accessibility in a region.

“…At this stage, the sufficiency evaluation of the provided statistical data amount of the TS to be analyzed is carried out. If necessary, an additional information collection on TS is performed and, based on the analysis, a conclusion is made about the achieved security level, "bottlenecks" and proposals to overcome the identified problems are formulated [4][5][6].…”

Ensuring safety in rail transportation is achieved by creating a certain management structure of the company, which contributes to the improvement of economic sustainability and organization of safe traffic. The analysis of indicators to assess the state of traffic safety in JSC “Uzbekistan Temir Yullari” (the object of the study) allowed the authors to formulate the purpose of the study, which is to develop algorithms for carrying out measures to ensure traffic safety on the basis of economic criteria of management efficiency. Following stages of planning as the analysis of indicators of safety and identification of problems, analysis of causes of the identified problems, development of ideas objectives, setting measurable goals, checking the achievement of objectives, developing options for action achieve the goals. For each stage on the basis of methods of correlation, regression and factor analysis algorithms of their carrying out are developed. The concept of measures is developed to improve the economic efficiency of traffic safety management, depending on the method of management. With the functional approach, the main direction of the plan is to strengthen control, and with the process approach-the regulation of technological processes and training of production personnel. The authors believe that the implementation of the proposed recommendations for decision - making on traffic safety is a comprehensive preventive measure to ensure a guaranteed level of safety, which will improve the overall economic efficiency of traffic safety management in the railway company.
