Résumé / Abstract
The in-actual use data collected within the DRIVE-MODEM project are used to characterize the resting period of the vehicles and the urban traffic conditions, and finally to build a Congested Urban Driving Cycle. Considering two diurnal cycles for the evaporative emissions test procedure should allow covering the great majority of the observed cases. The characterization of Congested Urban traffic conditions shows that the Standard Urban Driving Cycles describe badly the urban traffic. Statistical analyses and simulations have allowed the building-up of an Urban Driving Cycle, derived from real driving data, representative of the European urban traffic, with an average level of congestion. The tools, database and the method, are available to process any other simulation, in particular to investigate the highly congested urban traffic and the extra urban driving conditions.Mots clés libres : driving cycle;urban traffic;evaporative;emissions;test procedure;europe., RAPPORT DE CONTRAT
