AGREGATION of Type A Strategic Noise Cards with a large infrastructure type railway axis.

European Directive 2002/49/EC of 25 June 2002 on evaluation and management environmental noise involves an assessment for EU Member States environmental noise in the vicinity of major transport infrastructure (land and air) and in large urban areas. This assessment is carried out in particular through the development of strategic ‘so-called’ noise maps. the first series of which were drawn up in 2007 (1st deadline of the Directive) and 2012 (2nd deadline). Article L572-5 of the Environmental Code states that these maps are "reviewed, and, where appropriate, revised, at least every five years.’ Thus, the implementation of this review leads, in 2017 and as appropriate, to revise or renew the previously developed maps. This document presents the main results of this 3 rd deadline. which concerns the national railway network of the department of Pyrénées-Orientales. Noise maps are drawn up according to the indicators established by the Directive Eupenean, namely the Lden (Day Evening Night Level) and the Ln (Night Level). Each EU Member State defines its own periods (day, evening and night) knowing that the duration for each period is the same for all States (jour:12h/soir: 4h/night: 8h). In France, the periods were defined as follows: • Day/day: [6h-18h] • Evening/evening: [18h-22h] Areas exposed to noise (type A map) These are two cards representing • areas exposed to more than 55 dB(A) in Lden • areas exposed to more than 50 dB(A) in Ln
