VERIFICATION OF MATHEMATICAL MODELS FOR ROAD TRAFFIC NOISE PREDICTION OF TIRUPATI TOWN AT BLISS CIRCLE

摘要

Current increase in population growth have resulted in an increased transportation demand worldwide. Due to increasing motorization and Transport network, the noise level has exceeded the prescribed limits in many Indian cities. Migration of people from rural to urban areas, expansion of cities, infrastructure development, population growth and urbanization are important factors resulting in motorization and consequent increase in levels of various urban noise pollution. Traffic Noise pollution is an interfering air-pollutant which possesses both auditory and a host of non-auditory effects on the exposed population. Since there is no medicine to cure hearing loss, prevention to over exposure is the only alternative left. Therefore, the control of road traffic has become a matter of major concern for communities trying to maintain a satisfactory living and working environment. Traffic control systems used in modern cities can solve many traffic problems such as traffic jams, traffic incidents, delays, parking, fuel consumption, noise emission, air emission, and others. One such system, among other things, must include the model for traffic flows imitation and traffic noise prediction model. By using a traffic noise prediction model, one can calculate and examine the noise level in the processes of planning and designing. The present study measures traffic volume and noise levels during the peak traffic flow in the selected area of Tirupati town. The traffic volume studies are carried out by means of manual methods prescribed by Indian Standards and noise levels are measured following standard procedure using Sound Pressure Level Meter. The obtaining results are used to validate the existing mathematical models for the prediction of noise levels of Tirupati town.
