This API provides data on cycling infrastructure derived from the road network of the Eurométropole de Strasbourg, structured according to the French National Database of Cycling Infrastructure (Base Nationale des Aménagements Cyclables, BNAC) schema. This schema is designed to model and define cycling facilities consistently across national territory. Processing is based on a reference JSON file. The dataset is published via the Strasbourg open data portal and is freely accessible without authentication, providing structured, standardized information useful for mapping, planning, and analyzing cycling infrastructure at local and national level.Données issues du filaire de voie de l'Eurométropole de Strasbourg structurées dans un schéma permettant de modéliser et définir les aménagements cyclables sur le territoire national : la Base Nationale des Aménagements Cyclables (BNAC).
