Noise Round 3 Road (Lden)
This national dataset from Ireland's Environmental Protection Agency provides strategic noise mapping for roads exceeding the flow threshold of 3 million vehicle passages per year, as required under the third round of noise mapping. It is presented as polygon noise contours representing the Lden indicator (day-evening-night weighted noise level), covering the Dublin and Cork agglomerations as well as major roads outside these urban areas. The data supports assessment of environmental noise exposure from road traffic across Ireland.This is a polygon dataset of the strategic noise mapping of roads, which were identified as those roads exceeding the flow threshold of 3 million passages per year, in the form of noise contours for the Lden (day, evening, night) period for Dublin and Cork agglomerations and the major roads outsi...
