Modelling the Influence of Vehicle Technical Condition on Road Transport Related Emission of Harmful Gases in Serbia

The national vehicle fleet of the Republic of Serbia is recently becoming “younger”, compared to the fleet from the decade of the 1990’s. Nevertheless, today’s fleet is still characterized by poor maintenance and not very rigid vehicle inspection practices. Although the state opted for maintaining a yearly periodicity of vehicle inspections for passenger cars after an initial two years period (in case of newly purchased vehicles), vehicle inspection stations are literally competing for the market, and therefore became “tolerant to certain negligible faults” in order to attract clients. This is especially true for the emission of harmful gases, which, by their opinion, is not directly jeopardizing traffic safety. Meanwhile, there is still a significant import from the EU of used vehicles of a questionable (double-tampered) odometer state: firstly increased in order to avoid high import duties and later lowered so as to obtain a better selling price. There is no effective guarantee of the state a vehicle is in, mainly because of the lack of records (reliable data) regarding previous owner inspection and maintenance (I&M) habits, thus avoiding in this way the discovery of manipulations with total distance travelled. Therefore, the authors have chosen to model the relations between emissions and I&M practices in Serbia based on thorough analyses. After collecting relevant emission and I&M data for a vehicle category, as required by COPERT 4 emission assessment software, the aforementioned software will be used to estimate the national fleet’s total emissions of harmful gases. The emission assessment results will be compared to the referent (average) vehicle fleet and appropriately discussed in the paper.
