LIFE DYNAMAP: accuracy, reliability and sustainability of dynamic noise maps

In 2014 the LIFE DYNAMAP project moved its first steps towards the development of a system able to detect and represent in real time the acoustic impact of road infrastructures. Aim of this project is to ease and speed up the update of noise maps that, according to the European Directive 2002/49/EC on environmental noise, shall be delivered every five years. To that end, an automatic monitoring system, based on customized low-cost sensors and a software tool implemented in a general-purpose GIS platform, was developed and built in two pilot areas located along the motorway A90 that surrounds the city of Rome (Italy) and inside the agglomeration of Milan (Italy). After more than four years working, focused on the design of the system, the development of hardware and software components, the construction and testing of the pilot systems, the project is now approaching the final step, where the accuracy, reliability and sustainability of the system will be assessed. In this paper a general overview of the project and of the main results achieved are described.
