基于交通模型的道路机动车排放模拟研究

Simulation Study of Road Vehicle Emissions based on Traffic Model

该文以交通模型为基础,利用基于主干路段的小时机动车动态排放清单的ADMS-Urban模型模拟机动车主要污染物扩散。基于交通模型的道路机动车排放NOx、PM10、PM2.5、VOCs排放量分别是264吨/日、19.6吨/日、17.5吨/日、83.6吨/日;基于ADMS模拟的早8点上海NOx、PM2.5(一次)、VOCs高浓度主要集中在内环、中环、外环线上,主干路及高速路段两侧的高浓度距离约1km,最大距离出现在下风向的100m左右;14个敏感点模拟的NOx浓度在55-6161 ug/m3,西北风、东南风、静风NOx最大值在沪闵路北松公路口分别为14.5mg/m3、15.3 mg/m3、19.3 mg/m3。

Based on traffic model and hourly vehicle dynamic emission list on the trunk road,using ADMS-Urban model to simulate dispersion of vehicle pollutants.The amount of NOX,PM10,PM2.5,VOCs are 264 tons per day,19.6 tons per day,17.5 tons per day,83.6 tons per day separately.Based on the simulation result of ADMs in the 8a.m.,high concentration of VOCs focus in inner circle,middle circle and outer circle.The distance between two high concentration point are 1km.The concentration of the 14 sensitive points simulation are in range of 55 ug/m3 to 6161 ug/m3.The maximum of NOX under northwest wind,southeast wind and quiet wind are 14.5mg/m3,15.3mg/m3,19.3ug/m3 seperately..
