Map Viewing Service (WMS) of the dataset: Strategic map of noise railway infrastructure SNCF: type C Lden
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 where the noise level exceeds 62 dB(A) for high-speed lines and 65 dB(A) for conventional track in Ln (level night, night indicator from 22h to 06h). They are called ‘C-type card’.
Limit values in dB(A) are defined by article L572-6 of the Environmental Code.
The CBS for major railway infrastructure, whose annual traffic is more than 30,000 train crossings, by the deadline of the Val-d’Oise, were approved by prefectural decree of 5 December 2018.
They must be reassessed every 5 years.
