Nuisance — Type B Strategic Noise Maps, LNU index of Loir-and-Cher roads

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化评估。该指令将噪声地图定义为依据噪声指标描述噪声现状、标注限值超标情况与受曝露人群数量的数据可视化载体。 噪声地图不具备强制性规范属性。 此类文件属于参考性信息资料，不具备法律强制执行力。但作为可视化图形元素，其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基线基准与需要优化交通管理的重点区域。
