The article presents the materials of examinations carried out during a full-scale examination of the process of splicing a steel rope, conducting a magnetic defectoscopy and subsequent observations of the performance of a steel rope at the ski resorts of Krasnaya Polyana. The results of studies of the causes of the formation of “waviness” defects in the splicing section of the steel rope, as well as defects in the form of wire breakage of the steel rope in the splicing section and a defect in reducing and increasing the diameter of the steel rope in the splicing section are presented.

The article presents materials on the study of mathematical modeling of splicing (binding) of steel rope used to transmit traction by friction. The developed mathematical model splicing (binding) describes the stress-strain state of strands (wires) from quasistatic loads, arising in the cyclic tension process and bending of steel rope on rope sheave, in which the resultant force in steel rope cross section is shifted relative to the central axis, causing it to bend and torsion. Using experimental data, it was found that the steel rope torsion and bending is caused by the linking technology in the nodes where strands are replaced. Experimentally established, that defects on the splicing (binding) site manifested as a result of cyclic tensile and bending loads on rope sheave, which is connected to limited mobility of the strands in nodes due to cross section symmetry violation.

Air pollution monitoring in Rostov-on-Don and Rostov region is considered. The excess of the concentration of suspended solids over the national average is shown, especially near motorways and the busiest intersections. On the example of one intersection, field observations were carried out, and based on the developed computer programs, calculation of the main transport characteristics, the vehicle queue length at different phases of traffic light switching was carried out. The necessity of installing a "smart" (adaptive) traffic light is shown. The developed software products can be used to improve the organization of traffic flows and as a computer laboratory when teaching students in the specialty "Organization of transport processes".
