皇冠体育app speed-emission factor curve calculations used in the national transport model. 皇冠体育app curves have been updated with the latest speed-related emission and fuel consumption equations for different vehicle classifications, originally published June 2009.

皇冠体育app calculations relate emission factors, for the air pollutants NOx and PM10 in grams per kilometre, to average speed for each main vehicle class. 皇冠体育app classes are representative of the Great Britain fleets for 2003 to 2035.
