The air quality in the urban zone is influenced by many factors, of which transport plays a significant role. Air quality has an impact on the health of inhabitants, demographic, urbanization processes, as well as a whole mobility, and is currently one of the most important challenges faced by municipal authorities. The article focuses on analyzing the impact of exhaust gases and their emissions produced by motor vehicles on the environment in the opted territory, namely Hasičská Street in the city of Trenčín, Slovakia. Investigated and quantified emissions in the context of vehicles' mobility comply with a number of vehicles registered in Slovakia. The primary task of the research is to determine the amount of produced emissions in the researched area without the use of measuring technology. It is a process of modeling emission coefficients on the basis of which it is possible to reliably determine the level of pollution in the monitored area. The research per se is based upon a traffic survey carried out over the period September-October 2021. Following the analysis, obtained values were classified into certain vehicle categories registered in Slovakia while observing the relevant EU Regulations. The research involved measuring the volume of exhaust emissions produced by vehicles when in motion through the examined transport section. We further compared the resulting exhaust emissions with emissions automatically recorded by the national weather station. The levels of individual harmful substances registered by the Slovak Hydrometeorological Institute were naturally higher than the values achieved by the survey itself, as the weather station records emissions from multiple mobility activities. In regard to emissions obtained by the survey, we achieved related values of indicators as follows: CO, HC, NOx, and PM. The category of passenger cars topped the list, as automobiles produced 90.17% pollutants of all the recorded vehicles. Bus services capped NOx emission production. The highest emission rates were detected between 2 and 3 pm due to the peak traffic in the observed section. The analysis has proved significantly lower emission volumes produced by haulage compared to other vehicle categories.
