In the Greater Casablanca, road transport is the second largest emissions source of gaseous pollutants and particles after the industry [1]. The emitters are mobile and include different categories of vehicles in circulation, in the road network of the region [2]. Air emissions from road transport considered in this study are the exhaust emissions from combustion of fuel during vehicle movement. This is mainly SO₂ (sulfur dioxide), NOx (nitrogen oxides), CO (carbon monoxide), CO₂ (carbon dioxide), SP (suspended particulate) [3], VOC (volatile organic compounds), benzene, lead Pb and cadmium. These emissions depend mainly on the technology of the vehicle (type, fuel, engine size, and age), the vehicle speed, the engine temperature and ambient temperature [4].
