This dataset provides real-time traffic flow data for the road network arcs of the Eurométropole de Strasbourg, supplied by SIRAC (the local traffic monitoring system). Data is refreshed automatically around the clock, every three minutes, sourced from an XML feed. The dataset covers the main road network monitored by SIRAC and does not include all local streets. It is intended for applications and services needing up-to-date road traffic conditions within the Strasbourg metropolitan area.Ce jeu de données contient les arcs de trafic du réseau routier de l'Eurométropole fournis par le SIRAC.
