This dataset results from a high-throughput survey conducted on all roads open to motor vehicle traffic within the Eurométropole de Strasbourg (Strasbourg metropolitan area), France. It records horizontal road signage, classified into categories such as point markings (directional arrows, bicycle logos, pictograms) and other marking types. The data is published via the Strasbourg open-data portal and can be used for road infrastructure management, mobility planning, and analysis of traffic signage across the metropolitan road network.Ce lot de données est issu d'un relevé à grand rendement. Il a été effectué sur toutes les voies ouvertes à la circulation automobile de l'Eurométropole de Strasbourg. Trois classes ont été produites concernant la signalisation horizontale : - ponctuelle : flèche directionnelle, logo vélo, pastil...
