Sound ranking of departmental roads in the Var

Sound classification of departmental roads in the Var. Prefectural Decree of 01 August 2014 approving the revision of the noise classification of the land transport infrastructure (ITT) of the departmental roads (RD) of the Var department. In each department, the prefect is responsible for identifying and classifying land transport infrastructure into five categories according to their noise and traffic characteristics. After consulting the municipalities, the prefect shall determine the areas affected by noise in the vicinity of these infrastructures, the noise levels to be taken into account by manufacturers and the acoustic insulation to be observed when constructing a building. In addition to the regulatory requirements applicable to future buildings, noise classification of noisy tracks can serve as a basis for the competent authorities to carry out coherent local action in the field of urban planning and travel, with a view to preventing or reducing exposure to noise in the most affected sectors. Reference texts: — The noise law of 31 December 1992 laid down the basis for a new policy to protect itself against transport noise: Infrastructure developers must take noise pollution into account when constructing new tracks and modifying existing tracks, and must undertake not to exceed noise level thresholds, — Article 12 of the Noise Law, Decree 95-22 of 9 January 1995, Decree of 5 May 1995. Building builders, on the other hand, have an obligation to take into account noise generated by existing or planned noisy tracks, by providing their construction with sound insulation adapted to noises in the outside space — Article 13 of the Noise Law, Decree 95-21 of 9 January 1995, Decree of 30 May 1996. Article 13 of the Noise Law sets out the general principles for ensuring sound insulation of the façade of new buildings. — Articles R123-13, R123-14 and R123-22 of the Urban Planning Code: the municipality must report the sound classification information in the accompanying documents of the Local Urbanisation Plan. The principle of classification of noisy tracks Should be classified: — all roads with traffic exceeding 5000 vehicles per day whether it is a national, departmental or municipal road, — all tracks with traffic exceeding 100 trains per day, — all clean-site bus lanes (TCSPs) with average traffic of more than 100 buses/day. Land transport infrastructure (ITT) is classified according to its noise level, and areas affected by noise are demarcated on both sides (from the edge of the roadway for a road, from the outside rail for a railway). The widths of the nuisance areas to be taken into account for each track classified from category 1 (the noisest) to category 5 are: — in category 1:300 m. — in category 2:250 m. — in category 3:100 m. — in category 4:30 m. — in category 5:10 m. ITTs are therefore classified according to their noise emission level but also by nuisance sectors (open sector or U-based sector). Knowledge of the classification of inland transport infrastructure allows in particular developers and supervisors to incorporate technical provisions capable of ensuring sufficient comfort (e.g. acoustic isolation). Indoor noise levels are 35 dB(A) by day and 30 dB(A) at night.
