机动车尾气排放和扩散研究综述

随着社会经济和城市建设的迅速发展,机动车保有量急剧增加,造成交通拥堵问题日益严重,同时也导致了更为严重的交通污染问题。随着机动车尾气排放污染的日益加剧,对其研究也越来越广泛和深入。关于尾气排放的研究大致可以分为2个方面:(1)机动车尾气排放研究,从微观层面、中观层面、宏观层面对其进行研究,包括尾气排放获取数据的方法、机动车行驶周期及尾气排放模型的研究。(2)机动车尾气扩散研究,主要是其扩散模型的研究。此外排放控制策略研究也越来越受到重视,其研究趋势逐步由针对发动机改进等降低单个车辆的排放发展到整个路网的排放量改善的交通控制管理措施。

Review of Studies on Vehicle Emission and Diffusion

With the socio-economic and urban construction development,the motor vehicle ownership has been growing rapidly,resulting in the traffic congestion problem being increasingly notable,which is further causing serious traffic environment pollutions.As the vehicle pollutant emission getting worse,the research on emissions has been getting far-reaching.The studies on vehicle emission can be divided into two catalogs:(1) the study of vehicle emission from micro level,meso level and macro level,including the appr...
