Statistical result of urban driving cycles and emissions during an experimental campaign on road

Transport activities contribute significantly to air pollution and its impact on emissions is a key element in the evaluation of any transport policy or plan. There is a huge interest in evaluating the actual level of emissions across Europe and around the World as the amount of traffic increases globally. So, in the context of sustainable mobility, different aspects related to evaluation of vehicles pollutant emissions is still the subject of research studies. For this purpose, an experimental activity was carried out with a new Euro 5 diesel vehicle, driven along two tracks of Naples characterized by a different road gradient: the first pattern is quite flat, the second includes positive (+3.6%) and negative (-4.3%) road gradient. The statistical approach used takes into account different kinematic parameters including the effect of the slope in the street path. In this paper, some statistical results relative to a classification of driving behaviour in order to seek the best efficiency of the vehicle in terms of fuel consumption, emissions and performance during real trips are presented
