Dynamic noise maps are acoustic maps that depict in real time the temporal evolution of noise levels. In the DYNAMAP project two pilot areas have been identified to perform the dynamic maps in order to test the different requirements associated to major roads and agglomerations. The first pilot area is located in the agglomeration of Milan and covers a significant portion of the town, including different type of roads and acoustical scenarios. Roads have been classified and assigned to a suitable number of clusters, on the basis of traffic characteristics. Twentyfour roads representative of these clusters are continuously monitored to provide noise levels for the update of noise maps.
The second pilot area is located along a major road, i.e. the ring road (Motorway A90) surrounding the city of Rome. Nineteen devices have been installed at the top of portals located along the motorway to provide information on road noise levels and dynamically update noise maps. Three quarters of the ring road, for a total length of about 50 km, have been equipped with the new sensors.
