Welcome to Scotland's noise

The Scottish Government has produced these maps in response to the European Parliament and Council Directive for Assessment and Management of Environmental Noise 2002/49/EC, more commonly referred to as the Environmental Noise Directive (END). This directive deals with noise from road, rail, and air traffic, and from industry. It focuses on the impact of such noise on individuals, complementing existing EU legislation, which sets standards for noise emissions from specific sources.

The three main objectives of the directive are as follows.

To embrace their responsibility to deliver the requirements of the END legislation the Scottish Government published the Environmental Noise (Scotland) Regulations 2006. The Scottish legislation describes a two round process to manage environmental noise.

Task Detail
One Produce strategic noise maps for major roads, rail, airports, and industry
Two Competent authorities to draw up action plans to manage noise

The key differences between Round 1 and Round 2 are the criteria used to select the transportation links that are to be modeled. These are summarised in the following table.

  Round 1 Round 2
Major roads Roads with more than 6,000,000 (six million) vehicle passages per year Roads with more than 3,000,000 (three million) vehicle passages per year
Major railways Railways with more than 60,000 (sixty thousand) train passages per year Railways with more than 30,000 (thirty thousand) train passages per year
Agglomerations Agglomerations with a population of more than 250,000 (two hundred and fifty thousand) Agglomerations with a population of more than 100,000 (one hundred thousand)
Airports Airports with more than 50,000 (fifty thousand) air traffic movements per year and airports within agglomerations Airports with more than 50,000 (fifty thousand) air traffic movements per year and airports within agglomerations
