Linear noise mapping related to main road infrastructure noise (Contour_map, Lden). Representation of the isolevel curves relating to the acoustic descriptor Lden (day-evening-night level), referred to in Annex 1 to Legislative Decree No 194 of 19 August 2005. The elaboration was carried out for a 500 m band with respect to the road axis on both sides of the infrastructure with the following intervals: Lden 55-59 dB, 60-64 dB, 65-69 dB, 70-74 dB, ≥75 dB .
