Abstract
The volumes of freight and passenger traffic on the railways of the Russian Federation are increasing every year. Along with the increase in the transportation work, the likelihood of occurrence of undesirable incidents in railway transport increases. The assessment of the level of comprehensive (integrated) safety is an important scientific and technical problem in the current conditions of the functioning of railway transport. The methods used to assess the level of safety do not always meet the requirements of complexity in view of comparison of various-scale violations of traffic safety (crash, accident, faulty operation). The paper proposes a mathematical method for assessing the level of integrated safety in railway transport and calculation of the safety index of train traffic. For the calculation, statistical data for a certain period are used. These data summarized in a specialized dictionary of traffic safety violations, the mathematical treatment of which provides information on the level of integrated safety in railway transport in the Russian Federation. The proposed index allows determining the effectiveness of management decisions in the field of train traffic safety, as well as assessing the effectiveness of implementing certain innovations in the field of traffic safety. It is possible to use data on integrated traffic safety to reduce insurance premiums for cargo insurance on railways.
Highlights
Integrated assessment of technical safety is an urgent problem for all types of land, water, and air transport [1]
To obtain the indices of the integrated assessment of the safety level of train traffic, we developed the following mathematical model
This dictionary consists of different types of traffic safety violations (TSV) [11] on the railways, which include the concepts of crash, accident, special faulty operation and faulty operation, the causes of crashes, accidents, derailments and collisions of trains differentiated by the types of activity of railway transport facilities
Summary
Integrated assessment of technical safety is an urgent problem for all types of land, water, and air transport [1]. The need for safety is approved at the legislative level of the Russian Federation [2,3]. According to the official data of JSC “Russian Railways”, the annual growth in the volume of transportation by railways of the Russian Federation is from 5 to 10 percent. Because of the constant increase in transportation, the load on the rolling stock and railway transport infrastructure is increasing. Due to the increasing load, the issues of ensuring the safety of transportation process and, at the same time, assessing the level of safety of transport in general are becoming more urgent. The railway transport system is a complex integrated [4] sociotechnical system
