The study of vehicles’ emissions on the road network of the city of Chita

The article presents the results of studies on the distribution of vehicle ’s emissions on the road network of the city of Chita. The authors have developed a map of the city with information about the structure of traffic intensity. Traffic flow of the passenger cars predominates in the city. The predominant emissions from vehicles by the multiplicity of MPC are the concentrations of formaldehyde and benzopyrene. Trucks mainly bring benzopyrene on the road network of Chita. The maximum concentration of contaminants coming from vehicles is distributed in the lower part of the hollow. Limiting the movement of trucks or prohibiting the movement of trucks operating on diesel fuel during the winter period of the year (for the period of unfavorable weather conditions) will significantly reduce the concentration of benzapyrene in the street and road network of the city of Chita. Therefore, the ecological situation of the city will be improved.
