APIExecutable4/7Query nowOpen workbench Subscribe🇫🇷France

This dataset provides a type C map showing areas where regulatory limit values for railway noise, measured by the night-time indicator Ln, are exceeded: 65 dB(A) for conventional lines and 62 dB(A) for high-speed lines, for the 2022 reference year. It is part of a broader set of noise-related data published by the Eurométropole de Strasbourg (Strasbourg metropolitan authority) and is intended to inform residents and local authorities about areas affected by excessive railway noise levels during nighttime hours.Carte de type C indiquant les zones où les valeurs limites réglementaires pour le bruit ferroviaire pour l'indicateur Ln (nuit) sont dépassés : 65 dB(A) pour les lignes conventionnelles 62 dB(A) pour les lignes à grande vitesse Millésime 2022 Une information complète sur le bruit est disponible s...
