Abstract


Acoustic pollution evaluation along a highway with
land datas and GIS


During last few years noise pollution has become a relevant problem in urban and sub-urban areas. This is caused by industrial development and the progressive extension of the urban areas, but also by the spread of transportion systems. A reduction in traffic noise can be achieved in several ways: through correspondence of the source, the distance of propagation, or near the receiver. When it isn’t possible to act in those ways the only solution is to insert a screen (called noise barrier), which passively protects from noise propagation. After a short analysis of the motorway traffic acoustic impact, the paper presents a model for the optimal location of the noise barriers. The application of a mathematical model for localization of the noise barriers was executed beginning from the result of the application of the method of calculation of the noise from street traffic NMPB-Routes-96, carried out using a GIS software, related to highway with the relative attributes.
