The high traffic density in urban areas is one of the main sources of noise that degrade the general environment. As the traffic noise is more fluctuating than the industry noise, it inflicts more serious damage to the health of human beings and lowers their labour productivity. Therefore, the control of traffic noise has become a matter of major concern for communities trying to maintain a satisfactory environment in which to live and work. To ensure a high quality environment, methods for prediction of the noise emission of motor vehicles are necessary tools. In order to model traffic noise and select corresponding noise control measures, it is necessary to know functional relationships between noise emission and traffic volume of the various categories of vehicles. This paper attempts to establish the traffic noise predictions with the traffic volume of different categories of vehicles based on their established weights.
