Dataset Direct Download Service (WFS): Aggregation generic tables road noise zones type C index D — Tarn

Aggregation of generic tables describing the Noise Zones, for an infrastructure, the type of infrastructure concerned ROUTE (R), card type C and LD index. Road infrastructure concerned: A68, C1_albi, C1_castres, D100, D1012, D13, D612, D622, D630, D631, D69, D800, D81, D84, D87, D88, D912, D926, D968, D988, D999A, D999, N112, N126, N88 Limit value exceedance maps (or “type c” maps) maps to be made within the framework of the CBS pursuant to Article 3-II-1°-c of the Decree of 24 March 2006. 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. Aggregation obtained by the QGIS MIZOGEO plugin made available by CEREMA. Data source by infrastructure: CEREMA.
