FIFTH INTERNATIONAL CONGRESS ON SOUND AND VIBRATION DECEMBER 15-18, 1997 ADELAIDE, SOUTH AUSTRALIA MODELING OF URBAN TRAFFIC NOISE
The traffic noise, as main source in urban areas, makes up part of general environment problem which inflicts serious damage to the health of human beings and lowers their labor productivity. With little or no noise abatement legislation and by disregarding eventual noise control measures in sound source themselves and in urban environments, the traffic noise in cities may grow up alarmingly due to continued development of transportation infrastructure, to higher unit capacities and speeds of motor vehicles. 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. In order to modeling traffic noise and selecting corresponding noise control measures it is necessary to know functional relationships between noise emission and certain numbers of traffic parameters. The noise levels can be predicted by a mathematical model while designing planning and developments schemes for new transportation routes and re-development of existing ones or when the flow and composition of traffic are changed. In this paper, the results of modeling road traffic noise level by trending of the experimental data collected by systematic noise measurement at 11 measurement points in urban areas of Nis will be shown.
