Dataset Direct Download Service (WFS): AGREGATION of Type A Strategic Noise Cards with a large infrastructure such as Communal Way.

The European Directive 2002/49/EC on the assessment and management of environmental noise aims at a harmonised assessment of exposure to noise in the Member States. It defines them as representations of data describing a noise situation according to a noise indicator, indicating exceedances of limit values, the number of persons exposed. Noise maps are not prescriptive. These are information documents that are not legally enforceable. As graphic elements, however, they can supplement a Local Planning Plan (LDP). As part of an Urban Travel Plan (UDP), maps can be used to establish baselines and target areas where better traffic management is needed. Type A card: —Areas exposed to more than 55 dB(A) in Lden —Areas exposed to more than 50 dB(A) in Ln — LD (Lden) Sound level indicator means Level Day-Evening-Night. — LN (Ln) Sound level indicator for the night period between 22.00 and 06:00. Aggregation carried out with the QGIS MIZOGEO plugin made available by CEREMA. Data source: CEREMA欧盟《2002/49/EC号环境噪声评估与管理指令》旨在对欧盟成员国境内的噪声暴露情况开展统一化评估。本指令将噪声地图定义为基于噪声指标描述噪声现状、标明限值超标情况及暴露人口数量的数据表征形式。 噪声地图属于不具备法定强制执行力的信息文件。不过作为可视化图形载体，它们可作为地方规划方案（Local Planning Plan，LDP）的补充材料。 作为城市交通规划（Urban Travel Plan，UDP）的组成部分，噪声地图可用于确立噪声管控基线及需要优化交通管理的重点区域。 A类卡片： ——Lden指标下暴露于55分贝（A计权）以上的区域 ——Ln指标下暴露于50分贝（A计权）以上的区域 ——LD（Lden）声级指标指昼间-傍晚-夜间时段综合等效声级（Level Day-Evening-Night） ——LN（Ln）声级指标为22:00至次日06:00的夜间时段声级。 本数据集的聚合工作由CEREMA提供的QGIS MIZOGEO插件完成。 数据来源：CEREMA
