Abstract

On-road traffic can vary between weekdays and weekends, both in timing and magnitude. It influences atmospheric emissions behaviour and tropospheric ozone concentrations. Giving priority to the bottom-up approach, we developed the high spatial (1 km2) and temporal (1 hour) resolution EMICAT2000 model, to estimate atmospheric emissions for the year 2000 from Catalonia (Spain). Its on-road traffic component was built with a high-resolution digital road-map and considered the fleet of vehicles, traffic intensity and profiles for weekdays and weekends; for every highway and the most important roads and urban streets (daily average traffic > 5000). Most of the emission factors were taken from the top-down COPERTIII model. We used specific Carbon B
