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 Reading these cards requires some precautions detailed below.2002年6月25日发布的欧盟第2002-49号《环境噪声评估与管理指令》，为噪声管控政策确立了总体框架。 本数据集的编制依据为2006年3月24日发布的第2006-361号政令，该政令针对噪声地图与环境噪声防治规划的编制作出规范。 该指令明确规定需编制以下噪声地图与环境噪声防治规划： (1) 年车流量超过300万辆的各级公路及高速公路基础设施； (2) 年列车通行量超过3万次的铁路基础设施； (3) 该政令附件所列的人口规模超过10万的城镇聚居区。 2008年，法国朗德省（Landes）完成了噪声区划工作。本次初始诊断共形成四类噪声地图，基于四项统一的噪声评价指标编制：昼间-夜间等效声级（Lden，Level Day Evening Night）、夜间等效声级（Ln，Level Night）、Lden大于68dB(A)以及Ln大于62dB(A)。 2008年涉及的交通干线如下： —— 高速公路网：A63、A64； —— 国道网：RN10； —— 省道网：RD29、RD129、RD524、RD810、RD824、RD932E、RD947； —— 达克斯（Dax）市域道路网。 查阅上述噪声地图需遵循下述详细注意事项。
