Implementing the Dynamap system in the suburban area of Rome

The DYNAMAP project is a LIFE project aiming at developing a dynamic noise mapping system able to detect and represent in real time the acoustic impact due to road infrastructures. Dynamic noise maps are achieved by updating pre-calculated basic noise maps as a function of sound pressure levels and weather conditions, provided by an automatic monitoring system, made of customized low-cost sensors and of a software tool implemented on a general purpose GIS platform. The feasibility of this approach will be validated installing the system in two pilot areas with different territorial and environmental features: an agglomeration and a major road. The first pilot area is located in Milan, in a significant portion of the town, while the second one is situated along the motorway A90 encircling the city of Rome. The two pilot areas show peculiar needs and characteristics, such as the presence of multiple noise sources, roads junctions, traffic and weather conditions, that require different system's specifications. In this paper the main issues related to the preparation of the basic noise maps and the implementation of the Dynamap system in the suburban area of Rome are described.
