On the improvement of statistical traffic noise prediction tools

In this paper the authors propose a new expression to perform a traffic noise prediction by the collection of the acoustical energy sent to the receiver. The equivalent level, in fact, depends on the acoustical energy emitted by each passing vehicle, which can be directly related to its speed by some experimental relations. The main advantage of this procedure is that no measurements in situ are required in order to estimate the global noise level, with a consequent gain in easiness and time respect to other expression present in literature.
