The analysis of factors affecting the life of the elements of the transmission of the car. An assessment was made of the influence of vehicle operation modes on the reliability and durability of gearbox parts. Considered modern methods of lubrication of transmission elements av-car. A method is proposed for increasing the efficiency of lubrication of friction units by using an electric field and the formation of dipole structures of a lubricant on friction surfaces. The article was published as part of the implementation of the program of the International Forum “Victory May 1945.

The paper considers the existing analysis of traffic at the intersection of Ave. Lenina - st. Koroleva. A new scheme for the organization of traffic at the intersection is proposed, the calculation of the traffic light cycle is carried out, taking into account the introduction of new traffic lights. The results of the research will allow solving a number of problems of the road complex of the city of Donetsk to improve the transport and operational status of the existing network of public roads of local importance and the structures on them, bringing the technical parameters and the level of engineering equipment of the roads in line with the achieved traffic intensity.
