摘　　要：在对高速公路交通流特性分析和实测下风向污染扩散浓度的基础上,利用HIWAY-2扩散模式逆模型法和Mobile模式法分别对高速公路CO排放因子进行了评估。结果表明,除中型货车和特大型货车两种车型之外,用Mobile模式法算得的各车型排放因子均略高于逆模型法,而总体车流CO排放因子差异较小,分别为3.31g/(km·辆)和3.52g/(km·辆),与10年前相比降低了约88%。On the basis of the analysis on traffic flow characteristics on highway and the concentration measurement of downwind pollutant dispersion field,both HIWAY-2 dispersion model with inverse model scheme and Mobile model are used to evaluate the CO emission factor on highway.The results show that except medium and extra large trucks,the emission factors of all types of vehicles obtained with Mobile model are slightly higher than that with inverse model method,but the average CO emission factors of vehicle fleet are rather close,being 3.31g/（km · veh） and 3.52g/（km · veh） respectively,reduced by 88％ compared with that ten years ago.
