Ring road: results of the measurement campaign
Bruitparif - 19/01/2010
In order to complete the strategic noise maps made by the City of Paris and the 21 towns bordering it in Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne, Bruitparif launched a wide measurement campaign around the Paris ring road in spring 2009.
At the heart of the project, 8 permanent stations recorded 24/7 and second after second the noise generated by the traffic along the accommodations on both sides of the ring road. To complete this system, the laboratory vehicle, equipped with the most innovative technologies and autonomous in energy thanks to integrated solar panels, carried out about 50 one-hour-long recordings, that is, one site every 700 metres.
The objective was to precisely characterise the sound environment of the local residents and provide the authorities in charge of the traffic and the local authorities willing to decrease the environmental impact of the ring road with elements to answer the following questions:
- How does the noise vary according to the hours of the day or the types of day (work days, Saturdays, Sundays, school holidays)? Which periods are the noisiest or on the contrary the most quiet?
- How does the noise vary according to the traffic conditions (flow, speed, saturation, traffic composition...) and the layout of the location (ring road raised or sunken in regard to accommodations, presence of acoustic protections, distance between the ring road and the first accommodations, presence of service roads...)? Which traffic conditions are the biggest disadvantage in terms of noise? What are the relations between noise and air pollution?
- What is the contribution of inopportune events (sirens, horns, especially noisy two-wheelers, HGVs braking) in the ambient noise in comparison with the more continuous and permanent noise of the ring road traffic? What are the respective contributions of the different sound sources?
