Map Viewing Service (WMS) of the dataset: Sound classification of railways in Hérault

Land transport infrastructure is categorised into 5 categories according to the level of noise they generate, with category 1 being the noisest. An area affected by noise is defined on either side of the outer edge of the roadway, or of the outside rail, of each classified infrastructure.
In the department of Hérault, the Préfet carried out a review of the sound classification of infrastructures with six prefectoral decrees on 21 May 2014. This includes motorways, land transport infrastructure crossing the municipalities of more than 10,000 inhabitants, less than 10 000 inhabitants for the districts of Montpellier, Béziers, Lodève and the tramway lines of the Montpellier agglomeration.
Currently, the Hérault department has 7 prefectural sound classification orders: 6 above and one approved on 1 June 2007. Order No 2007/01/1064 of 1 June 2007 on the sound classification of railways and tramway lines in the department of Héault remains applicable to its articles concerning the sound classification of railway tracks. The revision of the latter is postponed to a later date, with an ex RFF network SNCF procedure at the regional level Languedoc Roussillon to be implemented.

陆上交通基础设施按其产生的噪声等级划分为5类，其中第1类为噪声最强的类别。受噪声影响的区域定义为每一处已分类基础设施的道路外边缘或外侧轨道两侧的范围。
在埃罗省（Hérault），法国省长于2014年5月21日通过6项省长政令完成了辖区内基础设施噪声分类的修订工作。本次分类涵盖高速公路、穿越人口超过1万的市镇的陆上交通基础设施，以及蒙彼利埃、贝济耶、洛代夫行政区内人口不足1万的市镇相关陆上交通基础设施，同时覆盖蒙彼利埃都市区的有轨电车线路。
目前，埃罗省共出台7项噪声分类相关省长政令：其中6项为2014年发布的上述政令，剩余1项为2007年6月1日获批的政令。2007年6月1日发布的第2007/01/1064号《埃奥省（Héault）铁路与有轨电车线路噪声分类政令》中，有关铁路轨道噪声分类的条款仍然有效。针对该条款的修订工作已延后至后续阶段，将由朗格多克-鲁西永（Languedoc-Roussillon）大区层面的原法国铁路路网公司（RFF）与法国国家铁路公司（SNCF）联合推进相关流程。
