Abstract

Background and Objective: Noise Pollution is one of the most important pollutants of the environment in urban areas and it is evident for everyone that one of the environmental problems is to reduce Noise Pollution to increase life quality and decrease its effect on citizens' health. The city traffic and vehicles are the major sources of Noise Pollution in large cities especially Tehran. Region 6 of Tehran is the most polluted area in terms of Noise Pollution. Therefore, a Noise Barrier in length of 511m and an area of 3066m which is situated in the western margin of Kurdistan highway and it is the only highway with the Noise Barrier in this region. This highway was chosen as our case study. Method: Feasibility studies and construction of Noise Barrier of the highway was implemented before changing the intersection of Kurdistan-Gomnam highway from coplanar to non-coplanar type. But the traffic and Noise Pollution situation changed following the changing of the intersection of the highway. In this study, we attempted to model Noise Pollution situation of region and the reducer role of Noise Barrier given the non-coplanar intersection in addition to overview of Noise Pollution situation of region by the traffic data of three streets leading to intersection and mean sound level at some points and examine improvement and or deterioration level of environment Noise Pollution. Findings: The modeled maps were compared in four groups after being prepared and the reason for the increase and decrease of the noise level in each situation was stated. Discussion and Conclusion: After comparing it was found that by eliminating the cross-level intersection with traffic lights in addition to lowering the noise level at 1. 7 m height, the vehicle traffic was also smoother and by distributing acoustic levels at different altitudes, due to the presence of Slope levels of overpass and overpass decreased overall Noise Pollution concentration at lower altitudes, and positive performance of the audio wall decreased slightly, and Environmental Management strategies were introduced to control Noise Pollution further.
