Urban road traffic noise on human exposure assessment using geospatial technology

The sounds produced by humans, industries, transport and animals in the atmosphere that pose a threat to health of humans or can be characterized as noise pollution. Adverse effects due exposure involve speech communication interference declining learning skills children. Highway traffic contributes 80% all noise. It has grown massive scale because growth population along roads leading rapid change land use evolved into common reality various Indian cities. main objective this work is develop road prediction model using ArcGIS 10.3 for busy corridors Chennai. collected data includes volume, speed, level lateral vertical directions. Noise levels were measured 9 locations meter. observed vary from 50 dB 96 dB. found problem severe 18% area, 6.3% people are exposed problem. results obtained study show city affected pollution traffic.
