Integral Assessment of the State of Railway Train Safety During Technical Audit

Abstract

Purpose. The research aims at developing an integrated assessment of the state of train safety at the railway during technical audit. Methodology. To develop an integrated assessment of the safety condition of train traffic at the railway during technical audit, it was proposed to use weight coefficients proportional to the impact of the negative consequences of catastrophes, accidents, incidents that characterize the state of train traffic safety violations at the railways. It was also suggested an orientation to the main indicators of train traffic safety in Ukrzaliznytsia JSC, which include: material damage, the number of traffic safety violations and technical equipment failures. Findings. The authors have developed an integrated assessment of the train safety state in the conditions of Ukrzaliznytsia JSC, which is a complex value designed to assess the overall level of traffic safety during technical audit. The authors also obtained models for the integrated assessment of train safety in Ukrzaliznytsia JSC with weight coefficients that allow more adequately reflecting the state of safety. These models can be used during technical audit of the entire railway, its individual enterprise or organization to find out the real threats and risks that have already arisen, and which need to be paid more attention to ensure a higher level of train safety. Originality. The authors firstly proposed, when conducting a technical audit, to use the developed models for an integrated assessment of train safety in Ukrzaliznytsia JSC with weight coefficients that allow us to assess the overall level of traffic safety and establish real threats and risks. Practical value. Based on the obtained models, for an integral assessment of train safety, technical audit of the entire railway or its separate unit can be performed with the proposal to implement appropriate measures to influence existing sources of danger in order to reduce risks and increase the local or general level of train traffic safety.
