The analysis of literary sources and the state of the problem in practice has shown that the level of gas pollution of the street and road network of Lviv by automobile transport significantly exceeds the maximum permissible norms. The level of gas pollution on the roads was determined based on the linear fuel consumption, and at the intersections – by the size of the maximum queues in front of them. The dependence between the change in the concentration of harmful substances on the roads from the intensity of the traffic flow is proved. It has been confirmed that the amount of emissions of hazardous substances by vehicles increases with increasing intensity of traffic flows, as well as with the modes of acceleration, braking, idling. Measures to reduce the level of air pollution by traffic flows are proposed.
