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. 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》旨在协调各成员国的噪声暴露评估工作。该指令将噪声表征数据定义为：依据噪声指标描述噪声状况、标明限值超标情况及统计受曝人数的数据集。 噪声地图不具备规范性约束力。此类信息文件本身不具备法律强制执行力，但作为可视化图形元素，可作为地方规划方案（"Local Planning Plan", LDP）的补充材料。 在城市出行规划（"Urban Travel Plan", UDP）框架下，噪声地图可用于确立评估基线，并划定需优化交通管理的重点区域。 本噪声地图依据2006年3月24日颁布的法令第3-II-1-b条制定，用于标示Lden与Ln声级限值超标的区域。 — LD（Lden）声级指标：指昼间-夜间等效声级（"Level Day-Evening-Night"）。 — LN（Ln）声级指标：指22:00至06:00夜间时段的声级指标。 本次数据聚合工作由CEREMA推出的QGIS MIZOGEO插件完成。 数据来源：CEREMA
