3 3 WHY THE DYNAMAP PROJECT? Directive 2002/49/EC Aim of the Directive is to define a common approach intended to avoid, prevent or reduce the harmful effects due to exposure to environmental noise. To that end, noise maps must be provided and updated every five years in order to report about changes in environmental conditions that may have occurred over the reference period

5 5 PROJECT OBJECTIVES The main objective is to reduce the cost of the noise mapping process through the development of a low cost sensors system able to automatically update the noise maps in real time. As a secondary objective, the project aims at demonstrating that dynamic mapping can be also applied to monitor and report the information related to other environmental parameters, such as those related to air quality, meteorological conditions, traffic, etc. Finally, the Dynamap system will be also equipped with a GIS web software application for public information and communication on noise issues.

7 7 THE DYNAMAP SYSTEM Wireless noise sensors Data collection. Data sent from the sensors are archived on a server Data analysis for calculation of Leq values of specific sources: 1 - Identification and removal of spurious events 2 - Calculation of sound level on a defined time basis Pre-calculated spatial noise map of Source 1 + Sound level of source 1 + Pre-calculated spatial noise map of Source n + Sound level of source n

8 8 MAIN STEPS OF THE PROJECT The project will be accomplished through four main steps: 1 Development of low cost sensors and tools for the management of real time noise maps on a GIS platform. 2 Design and implementation of two demonstrative systems in the cities of Milan and Rome. 3 Systems monitoring for at least one year to check criticalities, analyze problems and faults that might occur over the test period. 4 Provision of a guideline for the design and implementation of real time noise mapping.
