Dataset description

European Directive 2002/49/EC of 25 June 2002 on the assessment and management of environmental noise entails for EU Member States an assessment of environmental noise in the vicinity of major transport infrastructure (land and air) and in large agglomerations. This assessment is carried out in particular through the development of strategic ‘so-called’ noise maps. These maps are intended to be reviewed and revised every 5 years. The first series were developed in 2007 (1st deadline) and 2012 (2nd maturity). 2017 is therefore the year of the 3 rd deadline. CBS are required, in particular, for rail infrastructure with more traffic than 30 000 train crossings per year.; For major road and rail transport infrastructure, the CBS are established, decided and approved under the authority of the prefect of the department. Noise maps are developed according to the indicators established by the European Directive, namely Lden (Day Evening Night Level) and Ln (Night Level). • Day/day: [6h-18h] • Evening/evening: [18h-22h] • Night/night: [22h-6h] The Lden and Ln indicators correspond to a defined energy average over the periods (Day/Black/Night) for Lden and (Night) for Ln. The corresponding results are expressed in A or dB(A) weighted decibels.source: CEREMA Normandie centre — validity: prefectural Order of 27/02/2019
