DYNAMAP is a European Life project realized with the aim of developing a dynamic acoustic mapping system to detect and represent the noise impact generated by road infrastructures in real time. To this end, the project involved the development and installation of an automatic monitoring system, based on a limited number of low-cost permanent noise monitoring stations. Zone 9 in the city of Milan is the pilot area chosen for the implementation of the system. In particular, it is representative of a typical urban scenario. The ?real time? noise map is built starting from the data recorded by 24 noise sensors homogeneously distributed in the pilot area, each one representative of a number of roads sharing similar characteristics (e.g. daily traffic flow). To evaluate the accuracy and reliability of the system a testing campaign was prepared. The collected field measurements have been thus compared with the predicted noise levels of Dynamap system. Finally, a statistical analysis has been implemented to try to keep the error associated with such prediction below 3 dB and therefore optimize the system.
