ABSTRACT
With 35 km long and more than 100.000 inhabitants along its route, the Paris ring road (called in French "boulevard périphérique") is a recurring source of problems, in particular as regards noise pollution. A victim of its own success, bottled daily at certain times, the popular "Périph" allows a quarter of Parisian journeys and provides an important link that connects Paris and surrounding communities. Daily circulate in this ring near 300.000 vehicles.

In order to complete the strategic noise maps made by the City of Paris and the 21 neighboring communities belonging to the departments of Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne, in the spring of 2009 the Bruitparif company has made a significant measurement campaign. At the heart of the measuring device, 8 stations fixed rate recorded 24 h on 24, second by second, the noise generated by the movement on the edge of the road, in the neighboring houses located both on one side and the other of the ring. To complete the device, a vehicle laboratory, equipped with the most innovative technologies and autonomous energy, thanks to its integrated solar panels, it has made fifty measures an hour, ie a point each 700 m in length.
