The results of motor transport flow parameter complex analysis that affect the degree of the ground layer pollution in the atmosphere of cities are presented. It has been suggested that not only the emissions of exhaust gases from car engines, but also the wear products of vehicle assemblies and units should be taken into account during the environmental monitoring of motor transport flows. The regularities of harmful substance mass emission change on the parameters of the traffic flow were determined. They developed the mathematical model of the atmosphere surface layer contamination according to the parameters of the motor traffic flow taking into account the wear products of vehicle units and assemblies. They developed the algorithm for the ecological monitoring of motor transport flows, based on the dose approach and the predictive assessment methodology for the concentrations of pollutants in the surface layer of motor road atmosphere. A dose approach to the assessment of toxicity in the most polluted areas of SRN allowed to estimate the degree of surface layer toxic pollution concerning the atmosphere of motor roads in the districts of the city of Orenburg (0.0003 of total toxic doses on the average) and determine the greatest contribution to the total toxicity (benz(α)pyrene 68, 65%, acrolein 19.73%, formaldehyde 7.81%). They developed the program to inform road users about the pollution degree of the atmosphere surface layer on traffic flows.

Key words: road transport flows, transport work, emissions of harmful substances, ecological monitoring, exhaust gases, automobile tires, brake mechanisms, road surface.
