Aggregation of generic tables describing the Noise Zones, for an infrastructure, the type of infrastructure concerned ROUTE (R), card type A 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

They represent the isophone curves of 5 in 5 dB(A).
