Acoustical noise coming from road traffic is considered one of the most important noise source in an urban environment. Many studies have investigated the modelling of traffic noise, starting from experimental basis or from theoretical schemes. A topic still to be deeply investigated is the noise impact of road intersections and its optimization with respect to parameters such as traffic flow, vehicles average velocity, road typology, etc.. The aim of this paper is twofold: first of all the classification and the choice criteria of intersections are summarized; then the noise impact of different road intersections is investigated both on a review plan and on a software aided performance. The new idea introduced in this paper is to develop a "user friendly" tool for designers, able to produce noise maps easy to be read also by technicians that are not expert in acoustics issues, so that a designer could easily discriminate which typology of intersection better fits the area under investigation on the basis of a simple noise map or other graphical elements.

Abstract
Acoustical noise coming from road traffic is considered one of the most important noise source in an urban environment. Many studies have investigated the modelling of traffic noise, starting from experimental basis or from theoretical schemes. A topic still to be deeply investigated is the noise impact of road intersections and its optimization with respect to parameters such as traffic flow, vehicles average velocity, road typology, etc.. The aim of this paper is twofold: first of all the classification and the choice criteria of intersections are summarized; then the noise impact of different road intersections is investigated both on a review plan and on a software aided performance. The new idea introduced in this paper is to develop a "user friendly" tool for designers, able to produce noise maps easy to be read also by technicians that are not expert in acoustics issues, so that a designer could easily discriminate which typology of intersection better fits the area under investigation on the basis of a simple noise map or other graphical elements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
