Abstract: The role of road transport emissions in regional scale air pollution and acidification has been evaluated, using the Operational Priority Substances (OPS) model as implemented and applied for modelling acidification in Flanders, Belgium. Details concerning road transport emissions are discussed and model results are presented, focusing on the relation between road transport emissions and acidification. This includes modelling the impact of legislative actions (EC directives) and road transport scenarios for policy support. The scenarios have been based on emission factors derived from on-the-road traffic emission measurements in combination with national statistics on traffic numbers and vehicle types.

Keywords: acidification; air pollution modelling; nitrogen oxides (NOx); road transport emissions; road transport scenarios; sulphur dioxide (SO2).
