| The main aim of this study was to identify the limits within which the COPERT model can be reliably applied, with respect to minimum road length and maximum congestion level. This was made possible by comparing the COPERT emission factor trends with the fuel consumption of two passenger cars operating on real-world conditions. The experiment was conducted in an urban corridor (?Corso Lecce? in Turin) and on an urban highway (?M30? in Madrid). The consumption of vehicles was calculated by introducing their driving pattern in validated vehicle models developed with the AVL CRUISE software. There is a good agreement between COPERT and AVL CRUISE relative fuel consumption differences over a reference condition in most of the driving situations examined. However, the agreement degrades when moving to high saturation and short road distances. As general guidance, COPERT reliability increases as the link length increases above 400 m and the saturation level drops below 80%. If shorter distances need to be modelled at a macro level, then it would be safer to aggregate short links to larger conglomerates. Also, specific congestion corrections would be necessary for congestion levels when saturation exceeds approximately 80%. | |
