Sa？etak This paper describes and analyses concentrations of main traffic related air pollutants and their impact on air quality, which affects the quality of human life. The data are obtained from the measuring stations in Zagreb and Koroma？no (Croatia). These two places were chosen because of their diversity, related to traffic density – Zagreb is capital of Croatia, and Koroma？no is a small town in Istria region. Due to a specific way of pollution assessment, the data are presented in diagrams using an application, designed for this purpose, which enables easy comparisons and interpretation of the data. The results of this research indicate specific patterns of changes in the pollutant concentrations in relation to emissions of road motor vehicles
