Samenvatting
In the paper the methodology for air pollutants emissions estimate from road transport, developed within the EC project MEET, is applied to a case study of an urban road with gradient in the actual situation and in prevision up to 2010. The emission estimates are then used as input to standard CALINE4 dispersion model developed by California Department of Transportation to evaluate the concentration of carbon monoxide and nitrogen dioxide in the actual situation and in prevision to 2010. The results are compared with concentrations measured by air monitoring station in the road. The effects of road gradient and of dispersion model photochemical mechanism are finally discussed. (A)
