Attenuation of Road Traffic Noise by Vegetation in Urban Spaces
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2015, Vol 22, Issue 2
Abstract
The last decades of the 20th century and the beginning of the 21st century have been characterized by rapid urban growth of cities, which resulted in overcrowding and the lack of land. The aftermath of such circumstances is the construction of many buildings near the main roads and the bus stations, which causes population exposure to significant levels of noise. In the cities aimed at maintaining sustainable urban environment, greenery is a key element that can be used to approach this issue successfully. Green facades, also known as vertical greenery systems, are becoming increasingly popular in urban areas. Vertical green systems on the facade walls, low belts of green vegetation and trees of different heights, widths and lengths contribute to reducing the level of traffic noise. The ability of greenery to attenuate noise is greater with the increasing frequency of traffic. This paper describes the effects of certain types of vegetation on traffic noise reduction, depending on the parameters such as: the type of vegetation, the dimensions of the green belt, the distance from the noise source, frequency range, etc.
