Article is devoted problems of safety of traffic. In given article are sounded a number of the reasons of occurrence of failures on highways. In article questions of influence of psychophysiological features of drivers on occurrence accidents are considered. The special attention is given that use of cellular telephones by drivers (despite prohibition by traffic regulations), and also every possible advertising materials in sight of drivers do not promote concentration of attention on driving process. Also in article questions of increase of safety of pedestrians, as participants of traffic are mentioned. In article the interrelation between road conditions and safety of traffic is investigated. That fact is marked, the reasons of adverse influence of road conditions can be obvious and hidden. In article the developed practice of roads design is analyzed. The given practice, in a due measure, does not consider requirements of landscape designing. Which, in turn, though are registered in the arch of rules, but have recommendatory character. Also in article questions of use of the minimum parameters of highways are mentioned at its designing.

The problem of calculating rods for vector perturbations consisting of five components is solved: 1. kinematic transverse vibrations of the left end; 2. kinematic transverse vibrations of the right end; 3. dynamic bending moment at the left end; 4. dynamic bending moment at the right end; 5 dynamic uniformly distributed lateral load along the length of the rod. The transfer functions from each disturbance are obtained separately. Using these functions, we obtained the elements of the spectral matrix for stationary random processes, taking into account their correlation. The most common types of processes are considered: exponentially correlated random process; process with latent periodicity (with characteristic frequency); truncated white noise. The formula for obtaining the dispersion of displacement of sections is shown.

The model of the occurrence of failures as a result of aging of insulation materials of power cable lines is considered. It is shown that the residual life depends on the ratio of the safety margin and the ultimate strength of the materials used. A simulation of the resource actuation processes was carried out using a mathematical model of the insulation state that relates the time and probability of its trouble-free operation with certain parameters of it. The model allows to predict the state of the insulation and the service life of the power cable lines.

The paper considers an optical laser-free system for express analysis of vibration state, which includes a dedicated backlight and a videocamera of vision system, which is a displacement sensor. The problem of determining the degree of mutual influence of the reflecting properties of the surface and the spectral composition of the radiation of the light source on the noise level of the CCD matrix is ​​solved. Using dispersion analysis of the results of a field experiment, it was determined that the spectral composition of the backlight is the most significant factor; the best combinations of parameters were identified. Comparison of the noise level with the real vibration signal showed the crucial role of the selection of combinations of the backlight and the type of the reflecting surface.

The article is devoted to the problem of theoretical research and development of perovskite-based solar cells to optimize their design and increase efficiency. The paper presents a numerical simulation of the transfer and accumulation of charge carriers in the planar p – i – n heterostructure of a solar cell. The simulation is based on a stationary physico-topological model based on the diffusion-drift system of semiconductor equations. The efficiency of solar cells for different perovskite film thickness was obtained. It has been established that the maximum efficiency of the optimized design of a solar cell is about 27% with a perovskite film thickness of 500-700 nm and a defect concentration in it of the order of 1012 cm-3.

Currently, one of the main problems of our time is to improve the ecology of the regions. Green areas can contribute to this, however, the southern region of Russia is caused by a dry summer period. In this regard, there is the task of ensuring high-quality irrigation, which is often carried out by automated systems. However, without feedback, it is extremely difficult to bring the process to the proper level of quality. To do this, use humidity sensors, the price of which inevitably leads to a strong appreciation of the system. This article discusses the possibility and feasibility of developing and implementing its own moisture sensor that would meet such positive criteria as low cost, high accuracy and wide range of measurements, high corrosion resistance, versatility of application.
