ESTUDO PILOTO DO MAPA DE RUÍDO DE TRÁFEGO VEICULAR DA ÁREA DE INFLUÊNCIA DA RODOVIA TRANSAMAZÔNICA (BR 230) NA REGIÃO METROPOLITANA DE JOÃO PESSOA/ PB

Abstract

The sound sources propagated in the urban space, in particular the noise generated by automotive vehicles, have raised the levels of noise pollution in big cities. For the evaluation and control of the environmental noise, sound maps have appeared, which allows to represent the sound pressure levels active in the urban space. In the midst of urban expansion in Brazil, was inaugurated, in 1972, the third largest highway in the country, the Transamazon Highway (BR 230). As a result of this construction, there were transformations in the urban areas affected by it, especially in the State of Paraíba, since it is intersected by said highway along the greater extension, which comprises the East-West direction. When analyzing the cities of Paraiba where the Highway goes through, it was noticed that the Metropolitan Region of João Pessoa is the area with the largest number of buildings and, consequently, of people exposed to traffic noise coming from BR 230, the most critical area in relation to the emission of noise by the road. Thus, this work has the general objective to evaluate the impact of traffic noise of the Transamazon Highway (BR 230) in the metropolitan region of João Pessoa / PB to quantify the population exposed to noise and to statistically verify the correlation between road traffic noise and the conditioners physical-environmental. The current stage of the research presents the first results obtained in the pilot study for the municipality of João Pessoa. When comparing the resulting sound levels in the study area with the parameters established by NBR 10.151 / 2019 (ABNT, 2019), for the daytime period and predominantly residential use, it is stated that these are in disagreement with the 55 dB recommended by the standard. There was little difference between the resulting noise levels during the daytime period. This happened because the maps represent the most critical situations (morning and evening peak times). The dense vegetation present in the area results in the attenuation of vehicle traffic noise.
