Abstract
A simple method is here presented that essentially refers to recently released values of the pollutant emission factors, provided within the European "COPERT II" approach. The method is utilised for building up suitable indicators of the whole pollutant emissions for assigned mix of private (cars) and public (buses) transportation means.
These indicators are here utilised with the aim of comparing environmental and energy effects of different transportation policies, adoptable in a given urban area. Some modal changes in the transportation demand are then imposed, with the consequent properly re-allocation of the people mobility from private cars to public services. In this way, the effects on the released pollutants and on the energy consumption of different scenarios are compared.
The method only requires the knowledge of data concerning the running car fleet of the considered site.
