PLANNING-MODEL FOR THE ASSESSMENT OF AIR-POLLUTION CAUSED BY URBAN TRAFFIC

The following is a support model for urban area planning which allows the evaluation of the impact of measures taken regarding motor vehicle traffic on air quality. The model allows assignment of traffic flows to the road network, calculation of the composite emission factors usi ng the EEC-approved J-CORINAIR method, determination of both the emiss ion and dispersion of the primary pollutants and production of graphic al representations of the results. The results of its application in M ilan to determine the concentration of carbon monoxide and oxides of n itrogen caused by urban motor vehicle traffic, have been listed and wi ll serve as an example of its effectiveness.
