Hello, SUMO only generates the absolute pollutant amounts emitted by the vehicles. The pollution control board sets thresholds based on the ambient density of the pollutants which is affected by the background level as well as weather conditions. To convert from one to the other you need a more complex model and additional inputs. You may be able to obtain numbers for the estimated fraction of pollutants that come from traffic (from the authorities) and then use this to estimate the effect of changing traffic conditions on the ambient level.
