Dataset Direct Download Service (WFS): Table of Type C Strategic Noise Maps of a large highway-type infrastructure.

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. Carried out pursuant to Article 3-II-1-b of the Decree of 24 March 2006, the map represents the areas where the Lden and Ln boundaries are exceeded. — 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. data producer: Gamba/VINCI Highways《欧盟2002/49/EC号环境噪声评估与管理指令》旨在统一欧盟成员国的噪声暴露评估工作。该指令将噪声地图定义为：依据噪声指标描述噪声状况、标明限值超标情况及受噪声暴露人口数量的数据表征形式。 噪声地图不具备指令性效力，仅为参考性文件，不具备法律强制执行力，但作为可视化图表元素，可辅助地方规划方案（Local Planning Plan, LDP）的编制。 在城市交通规划方案（Urban Travel Plan, UDP）框架下，噪声地图可用于确立基准基线与需要优化交通管理的目标区域。 本数据集依据2006年3月24日法令第3-II-1-b条编制，所涉地图展示了Lden与Ln声级指标的超标区域。 —— LD（全称Lden）声级指标，即昼间-傍晚-夜间等效声级（Level Day-Evening-Night）。 —— LN（全称Ln）声级指标，适用于22:00至次日06:00的夜间时段。 数据生产者：Gamba/万喜公路（VINCI Highways）
