Simple download service (Atom) of the dataset: Strategic Map of Road Infrastructure Noise: type A Ln
Description
The strategic noise maps (CBS) are derived from the European Directive 2002/49/EC on the assessment and management of environmental noise. They are intended to inform the public about the levels of exposure to noise through graphic representations.
In accordance with article R572-5 of the Environmental Code, the CBS include maps of areas exposed to noise, called “type A map”, in Ln (level night, night indicator from 10 pm to 6 am).
The maps show the noise-exposed areas using isophone curves ranging from 50 dB (A) to 70 dB (A) and more by 5 dB (A).
The CBS of the major road infrastructure, whose annual traffic is more than 3 million vehicles, with a deadline for the Val-d’Oise, were approved by prefectural decree of 5 December 2018.
They must be reassessed every 5 years.
