摘要
为了高分辨率地评估微观交通区域汽车污染物的排放清单,引入了美国新一代交通排放模型MOVES,并分析了3种交通运行参数的敏感性;以典型平面信号交叉口为研究对象,通过实测及统计分析得到了反映汽车交叉口运行特征的运行模式分布;考虑交叉口信号灯不同方向的配时权重,运用MOVES模型评估了典型平面交叉口的PM2.5和CO排放清单;最后模拟了压缩天然气(CNG)替代常规燃料后交叉口PM2.5、CO的量化减排效益.研究结果表明,基于运行模式分布的排放评估更能反映交叉口汽车运行特征,计算结果更精确;CNG在公交车上推广后,案例中交叉口区域的PM2.5和CO排放清单分别降低66%和5%.
In order to estimate vehicles inventory in high resolution at a microscopic scale region, the MOVES model of US new version was introduced and the sensitivity of three traffic conditions parameters was analyzed. Taking a typical signal intersection as research object, the operation modes reflecting vehicles running charac- teristics in intersection were gained through field measurement and statistical analysis. In consideration of tim- ing weight in the different directions, the PM2.5 and CO inventories of typical intersection were calculated by MOVES model. Lastly, the efficiency of compressed natural gas （CNG） in the reduction of PM2.5 and CO was modeled when the buses conventional fuel was replaced by the alternative fuel （CNG）. The results show that, the traffic emission evaluation based on operating mode can better reflect the realistic vehicles＇ operation na- ture more, and calculate out more precise values. In the case study, the emission inventories of PM2.5 and CO in the intersection region were reduced by 66% and 5% respectively after the bus fuel of CNG was put into use.
