Study and Development of Road Traffic Noise Model.

Abstract

The major contribution of the traffic noise, towards overall noise pollution scenario, is a well known established fact. Traffic noise from highways creates problems for surrounding areas, especially when there are high traffic volumes and high speeds. Vehicular traffic noise problem is contributed by various kinds of vehicles like heavy, medium trucks/buses, automobiles and two wheelers. Many western countries have developed different prediction models based on L10, Leq and other characteristics. In India, the transportation sector is growing rapidly and number of vehicles on Indian roads is increasing at a very fast rate. This has lead to overcrowded roads and pollution. So, a need is being felt to develop a noise prediction model suitable for Indian conditions. A mathematical model was developed which is used for predicting L10 or Leq level, included three parameters (total vehicle volume/hr, percentage of heavy vehicles, average vehicle speed) for a site at Patiala- Sangrur Highway (NH-64) (1.5Km from Rajindra Hospital).
