It is shown that modern geometry cars, flaw detector cars and other track test cars provide reliable control of the technical condition of all hauls of the railroad track at “certain intervals of time”. Their number is limited and therefore “continuous monitoring” of all hauls is almost impossible. At the same time, in real life, due to the impact of various factors, such as seismic processes, certain changes take place even a day after control. The authors consider one option for continuous monitoring of the beginning of changes in the technical condition of the track using intelligent tools, which allow one, by analyzing the useful signal and the noise from the soil vibrations caused by the rolling stock, to create informative attributes for identifying the technical condition of the track. The application of traditional technologies of correlation and spectral analysis and other methods for this purpose does not allow ensuring adequacy of the control results. This paper proposes a technology for extracting and analyzing useful vibration signals, the noise of vibration signals and the relationship between them. The estimates of both correlation and spectral characteristics of the useful signal and the noise are used as the main carriers of diagnostic information. Due to the simplicity and the reliability of implementation of the proposed technical tools, they can be easily installed in one of the cars of all rolling stocks, providing control of the beginning of changes in the technical condition of the track during their movement in all hauls

This article is focused on two possibilities of perception of transport safety and transport systems. It describes basic characteristics and elements of road safety in the Czech Republic, and differences of safety in rail transport are also remembered. The article discusses traffic accidents as an indicator of road safety. The paper is created with examples of selection and processing of data transport systems, for road and rail transport of the Czech Republic.

Kryteria ochrony budowli przy eksploatacji górniczej pokładów w warunkach małego nachylenia określił Witold Budryk. Podzielił on obiekty na pięć kategorii ochrony, przyjmując dopuszczalne wartości wskaźników odkształcenia. Owe kategorie ochrony przyjęto za podstawę klasyfikacji obiektów na terenach górniczych.
