With the rapid development of economy in China, there has been a growth in motor vehicles, deteriorating the traffic pollution of roads year by year. The gas pollution, which mainly comes from complete and incomplete combustion of the fuel, includes CO, SO2, NOx, CO2, and VOC. Al, Ca, Fe and Mg and other non-enriched elements in the atmospheric particle originates from the road dust carried by the motor vehicle at the traffic junctions; the noise pollution emerges from the engine and tire friction. The primary methods applied worldwide covers MOBILE, OSPM and MVMS. For the noise pollution, FHWA and RLS90 are used. The roadside landscaping can absorb emissions, accumulate the heavy metal and reduce the dust and noise, which is an effective way to beautify the environment and prevent the pollution.
