Dataset Direct Download Service (WFS): Aggregation road noise zones type C index D — Alpes de Haute-Provence

Maps to be produced in the framework of the Strategic Noise Cards (CBS) pursuant to Article 3-II-1°-a of the Decree of 24 March 2006 and the European Directive 2002/49/EC on the management of environmental noise. Noise maps are not prescriptive. Aggregation of generic tables describing the Noise Zones, for an infrastructure, the type of infrastructure concerned ROUTE (R), card type C and LD index. Approved by prefectural decree of 08/08/2018. Road infrastructure concerned: A51, RN85, RD4, RN4a, RD4b, RD4085, RD4096, RD907 Limit value exceedance maps (or “type c” maps) These are two maps representing the areas where the Lden limit values are exceeded for the year in which the maps are drawn up. Lden: sound level indicator means Level Day-Evening-Night. It corresponds to an equivalent 24-hour sound level in which evening and night noise levels are increased by 5 and 10 dB(A), respectively, to reflect greater discomfort during these periods. The layers are produced by road axis in accordance with the COVADIS standard validated on 29 May 2017. Aggregation obtained by the QGIS MIZOGEO plugin made available by CEREMA. Data source by infrastructure: CEREMA and VINCI for A51 Strategic noise maps are reviewed every 5 years
