چکیده	Greenbelts are remarkably effective tools for minimizing traffic induced noise pollution. This study revealed the potential role of greenbelts along the roadside for the noise attenuation using various tree species of three different widths (25, 50 and 100m). Statistical analysis showed significant differences between stations. The reduction of noise level was also statistically analyzed. The results indicated that the greenbelts significantly contributed to the attenuation of noise pollution with positive correlation. The maximum noise level reduction compared to the open area was for trees and shrubs of 100m in width, and a mixture of conifers and broadleaves of 100m in width and 50m width by 44dB (A), 42.84dB (A) and 40.34dB (A), respectively. The results can be used as guidance for construction of tree belts for noise attenuation in environmental planning and management. Read More: http://www.worldscientific.com/
