Abstract: “This paper reviews the strategies so far recommended for modeling road traffic noise in India. An analytical model is developed to predict road traffic noise for busy roads of Delhi, India. Equivalent continuous sound pressure level, LAeqT is analyzed at different busy road locations of Delhi. A multiple linear regression analysis is conducted to predict the noise metrics LAeq, TNI and NPL in terms of traffic flow rate, percentage of heavy vehicles, and average traffic speeds. The model so developed is validated with actual experimental data.”

Keywords: Traffic noise, Equivalent continuous sound pressure level, LAeqT, Traffic Noise Index, TNI.
