Map Viewing Service (WMS) of the dataset: Sound rating 2020 — high traffic lanes in Toulouse-Métropole

Prefectural decree to review the sound classification of land transport infrastructure. The 2014 Order is repealed. The assessment and management of environmental noise in particular of land transport infrastructure is regulated in the Environmental Code in Articles L571-10 and R 571-32 to R.571-43 relating to the classification of tracks. The Order gives, for each of the sections of infrastructure concerned, classification in one of the five categories defined in the amended Ministerial Order of 30 May 1996, the width of the sectors affected by noise on both sides of those sections and the type of fabric. The layers of this folder are the surface materialisation of these areas affected by noise. According to Decree No. 95-21 of 9 January 1995, buildings to be constructed so-called sensitive (house, educational, health, care and social institution) in areas affected by noise must have a minimum acoustic isolation against external noise, as determined in accordance with the Ministerial Order of 30 May 1996 as amended.用于修订陆上交通基础设施声分类的府级政令，2014年相关命令予以废止。 针对陆上交通基础设施的环境噪声评估与管理，已由《环境法典》中涉及线路分类的第L571-10条及第R 571-32条至R.571-43条予以规范。 本政令针对所涉基础设施的每一路段，明确其归入1996年5月30日修订后的部长令所定义的五类之一，同时明确该路段两侧噪声影响区域的宽度以及相关构造类型。 本数据集的图层，为上述噪声影响区域的地表具象化表达。 根据1995年1月9日发布的第95-21号政令，在噪声影响区域内拟建的所谓敏感建筑（Sensitive Building，含住宅、教育设施、医疗保健机构、养护及社会服务机构），必须按照经修订的1996年5月30日部长令的规定，满足抵御外部噪声的最低隔声性能要求。
