Dataset Direct Download Service (WFS): Strategic Map of Iron Infrastructure Noise: type B

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 shall include maps of the areas affected by noise as defined by sound classification orders, known as ‘type B map’. Only classified tracks with annual traffic exceeding 30,000 train crossings are visible. Sound classification orders are rules of constructability applicable in the sectors defined on both sides of the channels classified in accordance with articles R. 571-37 and R. 571-38 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.
