The article considers a calculation method of track component failure resulting from high-level bending stresses caused by the movement of the rolling stock. The method is based on the probabilistic nature of stress value in components, as well as statistic data on the fatigue properties of the metal from which they are made. The method is approved by the calculation example of the most dangerous failure types of turnout components but it can find a wider application. By using this method, the evaluations of failure change can be obtained for all design components that carry a cyclic load on change of their operation conditions.

Problems of automation of individual modules and entire segments of integrated monitoring and surveillance systems for the transport infrastructure in areas with large concentrations of people and everywhere where it necessary to recognize certain objectives and their parameters are very relevant and timely. In this paper, the idea of determining the parameters of an object by its blurring is developed. It is assumed that a blurring is different for different colors, which decomposes a single image. It is offered as separate element of the study to consider the object boundary, which determines the sharpness. Placing objects according to the flat reference scale of blur changes, it can determine the distance from the observer to each of them.
