Research on the Quantification of Exhaust Emission Volumes in an Opted Road Section

Abstract

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.
