Noise maps on highways: Zoning with noise level (day, evening, night) > 62 decibels in the Landes department

European Directive 2002-49 of 25 June 2002 on the assessment and management of environmental noise sets the framework for noise control policy.

The data were produced in response to Decree No. 2006-361 of 24 March 2006 on the preparation of noise maps and environmental noise prevention plans.

It specifies that noise maps and environmental noise prevention plans are drawn up:
(1) For each of the road and motorway infrastructure with an annual traffic exceeding 3 million vehicles;
(2) For each railway infrastructure with an annual traffic exceeding 30000 train crossings;
3° For agglomerations with more than 100000 inhabitants whose list is annexed to the decree.

Noise zones were developed in 2008 in the Landes department. Four families of noise maps constitute the initial diagnosis according to four harmonised noise level indicators: Lden(level day evening night), Ln (level night), Lden over 68 dB(A) and Ln over 62 dB(A)

Axes concerned in 2008:

— motorway network:
A63 A64,

— national network:
RN10,

— departmental network:
RD29 RD129 RD524 RD810 RD824 RD932E RD947,

— Road network of Dax
