Effects of Different Greening Modes of Expressways on Air Environment

  • Jianfeng ZhangEmail author


The impact of highways on the atmospheric environment mainly refers to the dust generated by highways during construction and the pollution of vehicles discharged after the roads are opened. During the construction period, one of the characteristics of highway construction is that a large number of excavated soil foundations, ranging from hundreds of thousands of cubic meters to millions of cubic meters, cause dust pollution to be quite serious. The pollution generated during the road operation period mainly comes from the exhaust of the car. Automobile exhaust contains carbon monoxide (CO), nitrogen oxides (NOX), black smoke, hydrocarbons, aldehydes, and lead-containing particles. Car emissions are related to factors such as vehicle speed, operating conditions, and distance from the location of the vehicle to the contaminated location. When the car is driving at a constant speed, carbon monoxide (CO) emissions are inversely proportional to vehicle speed, while nitrogen oxides (NOX) are reversed. Nitrogen oxide (NOX) emissions increase with increasing vehicle speed. Automobile emission pollution is closely related to the level of road service. The emissions from vehicles with higher service levels are less than those with low service levels. In this chapter, the method of determining the SO2, NO2, and CO2 gas content is used to study the air purification effect of different greening modes (green belt, interchange intersection, entrance ramp area and service area green space) on the expressway side. The results showed that the roadside greenbelt has obvious purification effect on SO2, and the greening of the interchangeable interchange zone, the entrance ramp zone and the service zone have better absorption and purification effects on SO2 and NO2, while the impact of the highway greening on CO2 content is smaller.
