This paper presents an analysis of the relationship between the traffic emissions concentration and the traffic flow changes measured in the cross-section of one of the thoroughfares in Warsaw (Poland). The changes in meteorological conditions were also taken into account. The habitation in the vicinity of communication arteries with a substantial traffic flow, causes the more significant exposure to the influence of air pollutants. This is confirmed with statistically significant higher pollutant concentrations registered at the air pollution monitoring station localized near the relatively busy thoroughfare in comparison with stations situated in a certain distance of the direct impact of vehicular traffic. Air pollutant concentrations are best explained by the following independent variables: in the summer period - traffic volume, wind velocity, temperature and solar radiation intensity; in the winter period - traffic volume, wind velocity, temperature, atmospheric precipitation quantity and for PM10 - relative humidity as well.
