The QUIES project consists of a network of low cost acoustic sensors, installed in a portion of Turin's city area. This network is able to make a persistent acoustic monitoring and can transfer the information to a centralized database.
These measures are shown on a map in real time, allowing the user to depict noise trends over different time periods (daytime/nighttime, weekly, on specific dates).
Measurements are available in open format on the big data platform Smartdatanet, for further processing by third parties.
This project involves citizens through their smartphones, thanks to a special app for noise-detection and geolocation.
Our project has developed a capillary network of low cost sensors, that has been scientifically validated in terms of reliability for the detection of enviromental noise.
Our App for smartphones allows citiziens to use their mobile devices as instruments, sufficiently accurate for noise levels detection, according to the crowdsourcing model.
Collected data are exported to the Smartdata platform, which interconnects applications and objects distributed on the territory. The collected data and information are available for further processing and advanced analysis.
Data collected by sensors and smartphones are used to generate a noise map, using predictive analysis and interpolation models.
The total area amounts to 0.617 square kilometers, with a perimeter of about 4 km (3.94 km). According to the proposed areas, we have chosen 22 fixed locations, which are monitored by two weekly measurement campaigns.
The sensors's position within the territory is shown on the map below. Each sensor is represented by a marker: by clicking on each marker the last ten records kept by the sensor will be displayed in real time.
Every person that owns a smartphone can participate in the noise acquisition phase. Participants must download the QUIES application, available for Android and iOS platforms in the respective stores.
By clicking on the "Play" button it is possible to observe the noise level that is being measured by the device in real time. Measurements are sent to our server every 5 seconds. The application requires an active data connection and geolocation (GPS).
The platform targets public and private organizations that are interested in sharing their data and developing new applications, with the goal of creating and developing intelligent and sustainable communities.
Basing on data that were collected and used for developing the noise map modeling software, using reverse engineering, we have realized a graphical interface for visualizing maps with areas that are enclosed by the defined isophones.
