摘　　要：为改善2010年亚运会期间空气质量,佛山市对中心城区内部分道路进行试限行.采用欧洲COPERT模式,计算出不同排放标准、不同车速、不同车型下的机动车排放因子,通过交通流调查,获取限行前后典型道路交通流运行状态,并以此为依据评估限行后区内机动车污染减排效果.结果表明,限行期间,主要路段道路交通流量平均下降32.5%,车型比例变化较大,摩托车流量下降显著.各种污染物降幅比例并不一致.按照此流量降幅可以预计,如在区内全面展开机动车限行,单位路段污染物(CO、NOx、VOC、PM)年排放量分别下降48.1%、39.2%、43.6%、49.2%.To improve air quality during the 2010 Asian Games,temporal traffic control measures were made that some vehicles was banned to drive in certain roads in central district of Foshan from December 26 to 29 in 2009.The rate of vehicular emissions reduction was calculated,according to traffic flow parameters on-road including volume of traffic,speeds,the proportion of different vehicular types and vehicular emission factors.These traffic flow parameters were made based on traffic investigation,while vehicular emission factors related to vehicular emission standards,speed and vehicular types on-road were calculated after running the European COPERT model.The results showed that during temporal traffic control measures,the average volume of traffic on all roads in central district reduced by 35.2%,and the proportion of different vehicular types changed greatly,and volume of motorcycle decreased significantly.But the reduction rate of emissions of CO,NOx,VOC,and PM were unequal.So according to this reduction rate of volume of traffic,the average annual emissions of CO,NOx,VOC,PM on all roads in central district would decrease respectively by 48.1%,39.2%,43.6%,49.2%.
