Acoustical noise analysis in road intersections: a case study

Abstract

The modelling and the prediction of noise coming from vehicular flows is strongly related with the geometry and the general features of the road, including the presence of conflicting points. In an intersection configuration, in fact, noise cannot be predicted in a standard way, since the traffic slope depends on many random factors, such as priority, signals, traffic lights, driving behaviour, etc. In this paper, the author focuses on the noise prediction problems related to road intersections and on the analogy between electrical current and vehicular flow. An experimental activity on a case study in the Salerno University campus is presented and the results are compared with simulations made by a predictive software.
