Development of heterogeneous traffic noise level prediction model and Los at arterial road of nadiad city

Abstract

In developing countries like India, the nature of the composition of traffic is heterogeneous .A heterogeneous traffic flow consists of vehicles that have different sizes, speeds, vehicle spacing and operating characteristics. As a result of the widely varying speeds, vehicular dimensions, lack of lane discipline, honking becomes inevitable. Nadiad city has evidence a very rapid growth in urbanization which resulted in increased demand for transportation and at last it resulted in increased rate of noise pollution. Therefore, the traffic prediction models that are used for heterogeneous traffic conditions are nor applicable in heterogeneous traffic conditions. To increase the accuracy of noise prediction models, in depth understanding of heterogeneous traffic noise is required. Understanding the real traffic noise characteristic requires quantification of some of the basic traffic flow characteristics such as speed, flow, level of service, and density. In a given roadway, the noise level changes with density and level of service on the road. The noise prediction model will be developed based on various factors affecting noise.
