Considering the influence of motor vehicle traffic state on pollutant emission concentration in highway tunnel, the single vehicle pollutant emission factor model of highway tunnel is established. The emission concentration of NOx and HC is predicted by the single vehicle pollutant emission factor model basis of the traffic data of Taihu Lake Tunnel, which is verified by the traffic simulation software VISSIM. The results show that the concentration of NOx and HC in the tunnel will increase with the increase of traffic volume, the concentration of NOx will increase with the speed increasing, and the concentration of HC will decrease with the speed increasing. Finally, the proposed model shows significant performance gains when combined with the design data of Taihu Lake Tunnel.
