摘要：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".
