Abstract

The noise generated from the vehicular traffic flow is a major source of environmental pollution. The forecast of traffic noise levels is generally carried out using analytical models, which relate noise levels to some non-acoustic parameters connected to traffic fluxes and road characteristics. The noise generated from the vehicular traffic flow is a major source of environmental pollution. The forecast of traffic noise levels is generally carried out using analytical models, which relate noise levels to some non-acoustic parameters connected to traffic fluxes and road characteristics. All the noise prediction models consist of evaluating basic noise levels and making series of adjustment to take into account geometric, traffic flow, barrier data etc. In this paper, noise prediction models i.e. Federal Highway Administration (FHWA), and calculation of Road Traffic Noise (CORTN), have been discussed. The traffic Studies included are individual vehicle noise level, traffic noise level, traffic volume and traffic speed. Analysis of individual vehicle noise levels, computation methodology, paired t-test for FHWA and CORTN and other models have been studied.
