%X The measurements of the concentrations of the pollutants from the vehicles inside the 1560m-long Qidaoliang road tunnel in Gansu Province,the observations of meteorological conditions in the tunnel and the counting and classification of vehicles passing through the tunnel were conducted.The emission factors of CO,Hydrocarbons (HCs) and NOx from vehicles on mountain roadway in China were 41.861±26.101,5.367±3.158 and 3.883±1.943g/(km·veh),respectively,which were derived from the model of tunnel air quality based on the measured data.In comparison with the emission factors published by developed countries,the CO,and HCs emission factors of vehicles driving on mountainous road in China are much higher than those of the advanced countries.However,the level of NOx emission is lower than that of others.
