1. WHO defines health as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. See WHO (2011) Burden of disease from environmental noise: Quantification of healthy life years lost in Europe. http://www.euro.who.int/__data/assets/pdf_file/0008/136466/e94888.pdf
2. END required competent authorities to draw up "strategic noise maps" for major roads, railways, airports and agglomerations, using harmonised noise indicators L den (day-evening-night equivalent level) and L night (night equivalent level).
3. Scotland's trunk road network covers a distance of 3,500 kilometres with 1,900 bridges and 3,700 other structures.
4. Scotland's rail network comprises 2,729 kilometres of railway - 23% electrified - with 344 stations leased by First ScotRail and 4 others operated by Network Rail (Glasgow Central and Edinburgh Waverley), GNER (Dunbar), or a private company (Prestwick International Airport). Two thirds of rail passenger journeys were supported by the west of Scotland commuter network, and one third were elsewhere in Scotland.
5. Local authorities manage and maintain local roads, which comprise approximately 94% of Scotland's roads (around 56,000km).
