Noise zone on the road network of a Lden index type C strategic noise map

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.

《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协调的评估。本指令将噪声地图(noise maps)定义为基于噪声指标描述噪声状况、标明限值超标情况以及受噪声暴露人群数量的数据表征形式。
噪声地图不具备强制性效力。
此类文件属于信息类文档，不具备法律强制执行力。不过作为可视化图形元素，它们可作为地方规划计划(Local Planning Plan, LDP)的补充内容。
作为城市出行计划(Urban Travel Plan, UDP)的组成部分，噪声地图可用于确立基线基准与需要优化交通管理的重点区域。
