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

2002年6月25日欧盟发布的2002/49/EC号指令，旨在对环境噪声进行评估与管理，要求欧盟成员国对主要交通基础设施（陆地与航空）周边及大型城市区域的环境噪声开展评估。
该评估主要通过编制战略性噪声地图（业内亦称为“噪声地图”）来开展。首批此类噪声地图于2007年（指令首个截止期限）及2012年（第二个截止期限）完成编制。
法国《环境法典》第L572-5条明确规定，此类噪声地图"至少每五年进行一次复核，必要时予以修订"。因此，该复核工作需在2017年及后续适当时机开展，对此前编制的噪声地图进行修订或更新。
本文件呈现了第三轮截止期限下的主要评估成果，其针对的是东比利牛斯省（Pyrénées-Orientales）的国家铁路网络。
噪声地图需依据欧盟指令确立的指标进行编制，即等效昼夜噪声级（Lden, Day Evening Night Level）与夜间噪声级（Ln, Night Level）。各欧盟成员国可自行定义昼、晚、夜三个时段，但所有成员国的各时段时长保持统一：日间12小时、晚间4小时、夜间8小时。
法国的时段定义如下：
• 日间：[6时-18时]
• 晚间：[18时-22时]
噪声影响区域（A型地图）
此类地图包含两类区域：
• 等效昼夜噪声级Lden超过55分贝(A)的区域
• 夜间噪声级Ln超过50分贝(A)的区域
