Data indicating the level of noise according to the strategic noise mapping of all road sources within areas with a population of at least 250,000 people (agglomerations). Lnight indicates night time annual average noise level results in dB, where night is defined as 2300 - 0700. This data is a product of the strategic noise mapping analysis undertaken to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC).

Data indicating the level of noise according to the strategic noise mapping of major road sources within areas with a population of at least 250,000 people (agglomerations) and along major traffic routes with more than 6,000,000 vehicle passages per year. Lnight indicates night time annual average noise level results in dB, where night is defined as 2300 - 0700.This data is a product of the strategic noise mapping analysis undertaken to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC).

Data indicating the level of noise according to the strategic noise mapping of major road sources within areas with a population of at least 250,000 people (agglomerations) and along major traffic routes with more than 6,000,000 vehicle passages per year. Lden indicates a 24 hour annual average noise level with separate weightings for the evening and night periods. This data is a product of the strategic noise mapping analysis undertaken to meet the requirements of the Environmental Noise Directive (Directive 2002/49/EC).
