This dataset provides the traffic road segments (geometries) of the Eurométropole de Strasbourg road network, supplied by SIRAC, the local traffic management centre. These geometries serve as the spatial reference for the related real-time traffic flow dataset (SIRAC - flux trafic en temps réel). The traffic information covers only roads managed by SIRAC and does not include bicycle traffic. The dataset is published as open data via the Strasbourg data portal and is intended for use in mapping and analysing road traffic conditions within the metropolitan area.Ce jeu de données contient les arcs de trafic du réseau routier de l'Eurométropole fournis par le SIRAC. Ces géométries sont utilisées comme support du jeu de données SIRAC - flux trafic en temps réel . Les informations de trafic ne concernent pas le réseau non géré par le SIRAC. Le trafic "vélo"...
