Item The Method of Assessing Traffic Safety in Railway Transport(IOP Publishing, 2021) Bulakh, Marina O.; Baranovskyi, Denis M.; Muradian, Leontii A.EN: Abstract. To identify and predict risks in the work, a method for assessing traffic safety in railway transport is proposed. On the basis of statistics on the failure of freight cars during operation, the characteristic distribution laws for types of wear were determined. As a result, the dependences of the probability of failure-free operation of freight cars on the operating life were obtained and the centers of gravity of the areas that are used to characterize and assess the risk were determined. When designing a freight car, it is possible to establish risk values obtained on the basis of statistical data, which opens up the possibility of improving traffic safety in railway transport. In the developed method for assessing traffic safety in railway transport, the use of a graphical risk matrix is proposed. It is also proposed to combine the dependencies of the probability of failure-free operation of freight cars to calculate the total risk. This allows you to get a graphical risk matrix taking into account three types of wear of a freight car to assess traffic safety. The number of dependencies of the probability of failure-free operation of freight cars can be increased if failures are observed for other reasons.Item Proposals for Improving the Process of Forming Programs of Reforming the Railway Transport Industry(Дніпропетровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпро, 2018) Okorokov, Andriy M.; Bulakh, Marina O.ENG: Purpose. The purpose of the work is to develop proposals for improving the process of forming measures and programs for reforming the railway transport industry of Ukraine in the process of European integration based on research, comparison and generalization of information. Methodology. A study of the content and the main provi-sions of legal acts declaring the conditions for the reform of the railway transport was carried out using analysis and synthesis methods. Methods of the system approach, comparison and generalization of the obtained data allowed developing proposals for improving the process of the formation of activities and programs. Findings. The need for reforming Ukraine's railway transport has been under consideration since 2006, but for a long time reform was lim-ited only to the development of reforming plans and programs. Not being implemented within the framework of one program, the measures were reflected in the next or parallel one, with the corresponding change in the terms. The carried out analysis of their implementation does not allow talking about inactivity or denying the existence of posi-tive changes, however, given the duration of the period 2006-2017, they occur very slowly. This situation requires new approaches to the development of programs and activities, as well as assessing their implementation, one of which is proposed in the work. Originality. The work justifies the need to evaluate the implementation of measures and programs for reforming the railway transport industry by two criteria: legal and practical. The developed basic principles for the formation of programs for reforming and developing the railway transport industry provide an opportunity to receive timely and reliable information on the status of their implementation. Practical value. We obtained the possibilities of constant monitoring of the state of financial support for reforms and directions of use of funds, which will prevent their misuse and significantly accelerate the implementation of certain activities, and then increase their effectiveness.Item Risk System and Railway Safety(IOP Publishing, 2021) Bulakh, Marina O.; Okorokov, Andriy M.; Baranovskyi, Denis M.ENG: Abstract. When organizing transport processes on the railway, the most important component is the safety of railway traffic. Each country has a separate approach for assessing the safety of railway traffic on domestic railways. However, railway safety and other modes of transport is associated with technical or managerial risks. Assessment of the safety condition of traffic on Ukrainian railways is carried out by absolute and specific indicators resulting from statistical data. So far as the existing methodology for assessing the level of railway traffic safety does not provide a real and adequate picture, the problem of developing a risk system is relevant. The paper presents a risk system for assessing the level of actual and predicted safety of railway traffic. The risk system includes general, local, technological and technical risks. Each risk has a quantitative characteristic and can be applied to assess the safety of the railway traffic. The developed risk system is implemented as an application program and implemented at the railway enterprises of Ukraine. The presented system of risks and their posterior and priori values allow us to characterize the real state of railway traffic safety for the study period. Based on the obtained values of posteriori and priori risks, it is possible to characterize the actual and predicted safety of the railway traffic.
