Abstract

A vehicle emission model has been developed in order to estimate spatially desegregated emissions (highway, roads and streets) from road traffic using the ARC/INFO geographic information system (GIS), with a spatial resolution for each cell of 1x1 knf, and a temporal time-scales for the calculation of emissions on an annual, monthly, daily and hourly basis. The model takes into account the hot, cold and evaporative emissions and uses CORINAIR's emission factors. It considers the following pollutants: CO, NO* (NO and NOz), SOz, particles and several VOC. This model has been applied to obtain the emission inventory for Catalonia (Spain) for year 1994 from this source. The total amount of pollutants emitted is 407,309 tones/ye
