Dataset description

Areas where noise limit values are exceeded (concerning residential, educational and health buildings) within 24 hours (in Lden: day, evening, night): — 68 decibels for roads with annual traffic exceeding 3 million vehicles — 73 decibels for railway axes flowing more than 29000 trains per year This study complements the 1st deadline strategic noise maps developed by the Technical Equipment Studies Centre (CETE) in 2008 for road infrastructure with annual traffic of more than 6 million vehicles. In order to ensure uniformity of renderings, the entire line already mapped has been revised, beyond the recommendations of the Directive [1] requiring revision when the expected deviation exceeds ± 2 dB.
