In article traffic safety of vehicles on a straight section of the road is considered. Possibility of a road accident at sudden braking ahead of the going car for any reason is estimated. For safety of the movement and prevention of capacity reduction of the road because of emergence of a road accident the vehicles moving on a straight section of the road of big extent have to observe the distance determined by formulas.
Keywords: road capacity, road accident, traffic safety, minimum and safe distance
In this paper basic problems of safety control during metering complex development are observed. The system being analyzed was divided into two parts:low level (energy meters and GSM-concentrators) and high level (GSM-channel and server). These two parts analyzed before making models for each of them. The whole system is considered a queuing system, main techniques are observed. Analytic model is developed for low level of system, and imitational model is developed for high level. The most safety critical element is recognized. The resulting models could be used in future work as an event generators for analytic software.

In accordance with the theory of mathematical and statistical modeling, evaluation studies, selected the main characteristics of the models describing the studied production process of fiberboard using different types of binders. In accordance with the developed plan of the selected controlled studies, uncontrolled and controlled factors of the process under study. The levels, steps, and intervals of variation of the studied factors. As a method of obtaining the mathematical dependencies of the quality indicators of fibreboard from the kind of used binder was enacted active single-factor experiment. The results of the studies conducted statistical analysis of the dependence of physical-mechanical characteristics of the performance of the finished plate thickness fibreboard manufactured by wet and dry methods, interpretation of research results, quantitative and qualitative relationships between the studied parameters.

The powder samples of indoniobat lead relaxor ferroelectric prepared by intense mechanical action method in combination with shear have been studied. The dependences of the microstrains and mean square displacements оf the PbIn0.5Nb0.5O3 samples from the values of applied pressure have been investigated. The Integral intensities and half-width of some diffraction reflections have been determined by using X-ray diffraction method. The correlations between mechanical action and concentration and type of defects in the studied samples have been established.
