二、高速公路在不同交通服务水平时的环境影响预测(一)大气环境质量预测与分析1.汽车废气污染物排放源强的预测结果根据不同车速时各种汽车污染物排放系数,按照高速公路不同的交通服务水平,可以计算得出沪嘉高速公路汽车废气污染物的排放源强和污染物的分担率(如表8和表9所列)。由表8和表9可见,高速公路在不同的交
Forecast of Environmental Impact of Freeway at Different Traffic Service Levels (I) Prediction and Analysis of Atmospheric Environmental Quality 1. Prediction results of source emissions of vehicle exhaust pollutants According to emission factors of various pollutants of various vehicles at different vehicle speeds, according to the expressway Different traffic service levels can calculate the emission source intensity and pollutant sharing rate (as listed in Table 8 and Table 9) of Shanghai-Jiaxing Expressway automobile exhaust pollutants. It can be seen from Table 8 and Table 9 that the expressways are in different handovers
