FHWA Model for Predicting Traffic Jam Noise in Varanasi City India

Kanakabandi Shalini, Brind Kumar


Industrial and transport activities are the two major sources of noise pollution in any city. Most of the cities in India are facing serious noise pollution problems due to the concentration of motor vehicles and human population within the limited urban areas. Varanasi is the spiritual capital of India on the banks of the Ganga in Uttar Pradesh has an area of 1,550. Km2. The population of Varanasi city as per census 2011 is 1,201,815. Main source of noise was vehicular traffic. A study has been performed in Varanasi city to assess the noise levels at selected locations with heavy traffic. Equivalent noise levels were measured at ten different traffic jam locations. From the data it was found that noise levels at all selected locations were much higher (70–90 dB(A)) than the prescribed limits. Federal Highway Administration Agency (FHWA) model was used to predict noise levels and the calculated noise levels were compared with the observed levels for checking the suitability of this model. It was observed that the results obtained by FHWA model were very close to the observed noise levels.
