Abstract

This paper treats the problem of traffic noise in roads which have been transformed into big avenues in the city of Curitiba and its impacts on the community. Simultaneous measurements of noise levels, vehicle flow, and traffic composition were made around the main roads inside the urban perimeter of Curitiba. Mathematical models were then developed to estimate sound pressure levels. The measured levels were compared with the mathematical models as well as with the results using the German Standard RLS-90. The validity of the developed mathematical models was thus confirmed as well as the applicability of the calculation method adopted by the German Standard RLS-90. Finally, the traffic noise levels around these roads were assessed by the application of the noise urban limits of the municipal law 8583/1995.
