This article analyses the traffic accident rate on roads and highways and possibilities of risk evaluation related to traffic accident occurrence based on factors that were the causes of accidents. A new term – risk of traffic accident occurrence is a product of probability of accident occurrence and its impacts. The results are presented by way of example that uses selected statistical data of the Slovak Republic traffic accident rate between 2002 - 2012. The article provides a brief methodological procedure of evaluation of the traffic accident rate using the risk of traffic accident occurrence.
The paper deals with ways of applying mathematical methods to evaluate the result of tribodiagnostics related to vehicle combustion engines. The idea is based on a discriminative analysis that makes possible to describe one qualitative parameter (complex technical state) by means of several quantitative parameters (i.e. quantity of diagnostic parameters). The results have been verified by means of considerable statistical data of T-3-930 engines made in the Czech Republic which are used in ground vehicles.

W artykule przedstawiono sposób wykorzystania metod statystycznych do oceny wyników badań tribodiagnostycznych silników spalinowych. Przyjęta metoda oparta jest na analizie dyskryminacyjnej, umożliwiającej opis jednego parametru jakościowego (złożonego stanu technicznego) za pomocą kilku diagnostycznych parametrów ilościowych. Wyniki badań zostały zweryfikowane na podstawie danych statystycznych silnika spalinowego T-3-930, wyprodukowanego w Republice Czeskiej, który stosowany jest w pojazdach drogowych.
This article analyses the traffic accident rate on roads and highways and possibilities of risk evaluation related to traffic accident occurrence based on factors that were the causes of accidents. A new term-risk of traffic accident occurrence is a product of probability of accident occurrence and its impacts. The results are presented by way of example that uses selected statistical data of the Czech Republic traffic accident rate between 1993-2001. The article provides a brief methodological procedure of evaluation of the traffic accident rate using the risk of traffic accident occurrence.
