Effect of Traffic Volume and Speed on Noise Level Under, Interrupted and Uninterrupted Traffic Flow Condition - A Case Study on NH ? 7

Noise is a disturbance to the human environment that is escalating at such a high rate that it will become a major threat to the human beings. Traffic related noise pollution accounts for nearly two thirds of the total noise pollution. Traffic noise from highways creates problems for surrounding areas, especially when there is a high traffic volume and speed. The present study emphasis on the effect of traffic volume and speed under interrupted and uninterrupted traffic flow conditions. It was observed from the analysis that noise level at both traffic flow conditions were within the permissible limits. The influence of volume on noise level shows that noise levels is higher under interrupted traffic flow condition and similarly for speed on noise level indicate that the noise level is higher on interrupted traffic junction than uninterrupted junction.
