Abstract
Presented are the results from investigating the modern motor transport flows in summer 2019 on the territory of the Irkutsk agglomeration (Irkutsk, Shelekhov and Angarsk). Visual observations on the territory under study were made for the first time. A study was made of the intensity of traffic flows of the main types of transport (passenger, goods and autobus vehicles) in the functional zones of the cities of the agglomeration. The amount of fuel burned and the most harmful pollutants emitted to the atmosphere by one automobile is determined. Calculations showed that in all cities the values of emissions of toxic substances in the form of carbon monoxide, nitrogen oxide, sulfur oxide and soot are significant but do not exceed MAC. The functional zones of the cities differ not only in the character of motor transport flows but also in content of emissions. The transport flows in Irkutsk and Shelekhov have similar features, and a somewhat different situation is observed in Angarsk.
