METHODOLOGY FOR THE DETERMINATION OF SPECIFIC FACTORS OF ROAD TRANSPORT EMISSION

Abstract

Most of the air pollution originates from combustion processes, whereby traffic is one of the most important sources. Road traffic is one of the leading factors of pollution, so determining its contribution pollution and overall emissions is very important. This study is a tool to develop a calculus method to determine the specific and annual emissions from road transport. The estimation was carried out using the methodology developed for combustion analysis. The study was based on vehicle fleet composition, fuel, and engine data, which represented the input for the combustion process simulation, while the output was combustion products. The following gases (chemical species) were included in the analysis: CO2, CO, and NOx. In the end, the specific emission factors, as well as bulk emission factors for urban and open road transport were derived. The results showed good agreement with the results of other authors.
