Traffic Noise Study on Muzaffarnagar Byepass

Abstract

Noise Pollution has become a major concern to planners, regulatory agencies affecting individuals and communities. Most of the countries, keeping in view the alarming increase in environmental noise pollution has set permissible noise standards. Road surface, speed of the traffic, gradient of the road, traffic flow etc. are the different factors affecting noise level on a highway. The Bureau of Indian Standards (BIS) has  recommended an acceptable noise level of 25-35 dB (A) for non-Urban areas. A number of noise predicting models have been developed over the past 30 years that attempted to model the highway conditions under study. Useful correlations has been found to exist between traffic parameters like traffic volume, average speed of traffic stream and noise parameters like Equivalent sound energy level (Leq) in the locations. With the help of these correlations, it is possible to predict the impact of traffic developments in terms of noise pollution in future.
