API providing a type C map dataset identifying areas within the Strasbourg metropolitan area, France, where regulatory railway noise limits are exceeded, based on the Lden indicator (day, evening, night), for the 2017 reference year. Thresholds are set at 73 dB(A) for conventional lines and 68 dB(A) for high-speed lines. The dataset is published via the Strasbourg open data portal and is intended to provide comprehensive information on rail-related noise exposure in the area, useful for environmental assessment, urban planning, and public information purposes.Carte de type C indiquant les zones où les valeurs limites réglementaires pour le bruit ferroviaire pour l'indicateur Lden (jour, soir, nuit) sont dépassés : 73 dB(A) pour les lignes conventionnelles 68 dB(A) pour les lignes à grande vitesse Millésime 2017 Une information complète sur le bruit es...
