Emission measurements have been conducted in the three laboratories in France, Germany and UK on the basis of driving cycles representing the driving behaviour in urban areas. The driving cycles are derived from driving behaviour data collected in Marseille, Grenoble, London, Derby, Cologne and Krefeld. The cycles cover the whole range of vehicle speed and acceleration in urban traffic. The selection of 150 vehicles used to determine the emission data sets is based on the stratification principle because the aim was to adapt the emission data sets to the various compositions of the vehicles populations in the different European Community member states. To meet this requirement, the selection should be in the form of layers. The layers were defined such that the various automobile types gathered in one layer show but comparatively little difference in their emission behaviour. In this paper the mean emissions and fuel consumption of different vehicles concepts classified into 11 layers are presented for 14 so celled modem cycles. In addition this report contains a description of the methodology for modelling exhaust emissions and fuel consumption on the basis of continuous emission measurement. In order to describe driving behaviour the instantaneous cycle speed (v) and the product of speed and acceleration (v.b) were selected, because these two parameters can be interpreted as standardized related output proportions of the applied engine output. The model is given in the form of a two dimensional function with the variables speed (v) and speed times acceleration (v.b) for all vehicles concepts.
