Abstract: | In the rapidly urbanizing country like India, the transportation sector is growing rapidly, which lead to overcrowded roads
producing air and noise pollution. Noise of a particular region is influenced by the volume of traffic on the highway, in
addition to other causative factors like existing infrastructure and industrial setup etc. In the present paper, a geographical
information system (GIS)-based noise simulation model has been developed to generate noise levels in Versova region of Mumbai,
India. The study area comprises effect of infrastructure, road network, traffic volume, and various mechanical components
like sewage pumping station and wastewater treatment facility. Various meteorological parameters and effect of land use and
land cover on noise attenuation are also considered in the model. In this way, commutative noise prediction for point as well
as mobile sources has been presented in the study. GIS-based noise simulation has been calibrated with observed noise levels
during day and night time with correlation of 0.84 and 0.74, respectively. |
