Therefore, for calculating emissions, emission factors have to be multiplied by the number of vehicles and kilometers driven. If you are focusing on a road only, then you can multiply the number of vehicles/hour *EF * distance from the road, so you can have an estimate of the emissions per average hour. <br />Best regards EEA Communication Thu, 31 May 2018 09:29:07 +0200 https://community.eea.europa.eu/home/environmental-topics/air-emissions/hello-i-am-trying-to-determine-the-pollutant-concentrations-of-vehicles-in-a https://community.eea.europa.eu/home/environmental-topics/air-emissions/hello-i-am-trying-to-determine-the-pollutant-concentrations-of-vehicles-in-a Hello, I am trying to determine the pollutant concentrations of vehicles in a city by using emission factors (g / km), but how can I adpate these factors using vehicle/hour data?
