| This paper introduced IVE model and presented the method to quantify the main parameters by taking Beijing city as a case. Emissions from different vehicle fleets of Beijing were calculated using IVE model. The results showed: emissions factors of buses and trucks were much higher, especially for PM, which were 14 and 44 times those of passenger cars. The daily CO, VOC, NOx and PM emissions of vehicles in Beijing city were 2767.4, 182.5, 353.8 and 7.1t respectively. Common light duty vehicles were the main emission source of CO and VOC, with the contribution of 42.0% and 34.7% respectively, Trucks were the largest contributor of NOx and PM emissions, with the contribution of 66.3% and 83.0% respectively. In addition, this paper compared the methodology and calculating results of MOBILE6 and IVE model, and discussed the advantages of IVE model’s application in China. |
