Map visualisation service (WMS) of the dataset: Type A Strategic Noise Maps of a Large Infrastructure Type Rail Axis LN.

The European Directive 2002/49/EC on the assessment and management of environmental noise aims to assess noise exposure in a harmonised way in the Member States. It defines them as data representations describing a noise situation according to a noise indicator, indicating exceedances of limit values, the number of people exposed.
Noise maps are not prescriptive.
They are information documents which are not enforceable at the level of law. As graphic elements, however, they can complement a Local Urban Plan (PLU).
As part of an Urban Travel Plan (UDP), maps can be used to establish baselines and target areas where better traffic management is needed.
