The paper presents an attempt to evaluate the exhaust emissions generated by transport in the Poznan agglomeration. The basis for the modeling of the exhaust emissions was the on-going characteristics of the individual groups of vehicles and a forecasted structure change of these groups for the years 2012–2030. The determination of average on-road emissions as a function of daily distance covered by individual vehicle groups was the basis for the determination of the change in the annual pollution. The assumed values of the exhaust emission concentrations from passenger vehicles were based on the performed tests under actual traffic conditions while for the other categories the authors adopted the test results of earlier works of the research team with the Chair of Combustion Engines at Poznan University of Technology. In the paper the authors assumed an increase in the share of vehicles meeting the latest applicable emission standards as well as changes in the distance covered by the vehicles. The result of the analysis will be accumulated annual exhaust emissions for a given vehicle category operating in the Poznan agglomeration. Keywords: exhaust emission, real road conditions, modeling.
