TRANSPORT ACCIDENTS DISTRIBUTION AT UKRAINIAN RAILWAYS ACCORDING TO CATEGORIES DEPENDING ON SEVERITY OF CONSEQUENCES
Abstract
Purpose. The article aimed at developing a methodology for transport accisents distribution according to criterion of average material damage and establish financial limits between the existing types of transport accidents. Methodology. Nowadays, at the Ukrainian railways, transport accidents are classified according to the severity of consequences which are expressed in physical quantities. The existing classification system is inferior to the classification system of transport accidents, which operates in the territory of the European Union (EU). Transport accidents in the EU countries are classified both by type and by criterion of material damage. To distribute transport accidents by categories depending on the severity of the consequences at the Ukrainian railways the method of the nearest neighbor is used. It takes into account average losses from transport accident, its feature is the possibility of establishing financial limits. Findings. The article proposes an efficient method for distributing transport accidents at the Ukrainian railways according to the categories depending on the severity of consequences using cluster analysis. The presented results of calculations allow us to distribute the transport accidents into three groups and establish the financial limits between them. Originality. It was improved the method of distribution of transport accidents by categories depending on material losses. According to it, transport accidents are divided into three groups. For the first time, financial limits were proposed between groups of transport events. We propose further research to confirm the size of financial limits. Practical value. As a result of research, it was possible to evaluate transport accidents not only by severity of their consequences, but also by the criterion of material damage. This approach also enables us to evaluate the state of traffic safety at certain sections, stations or railway directions. On the basis of obtained results, further development of classification system of transport accidents, as well as its integration into the European classification system, is possible.
