Simple download service (Atom) of the dataset: Noise-exposed areas in Haute-Savoie (Ln)
Description
Areas exposed to noise levels above 50 dB(A) along roads with annual traffic exceeding 3 million vehicles.
These areas are bounded by isophone curves calculated according to the Ln indicator, with a step of 5 in 5 dB(A), for the drawing up of strategic noise maps along the road infrastructure of Haute-Savoie.
LN is a noise level indicator for the night period (22h-6h).
An extraction for a route may be produced by DDT 74 by sending a message to the contact.
