Comptage du trafic routierRoad traffic counts
This dataset locates measurement points along road network segments in the Canton of Geneva where traffic data is recorded. Currently only vehicle flow values are available, expressed as the number of vehicles per hour at a given measurement point. It is published by the Geneva territorial information system (SITG) and provides free, unauthenticated access to local traffic-monitoring data, useful for transport planning, congestion analysis, and infrastructure studies within the canton.La Couche comptages localise les points de mesures sur un troncon du réseau routier pour lequel des valeurs de trafic sont relevées. A ce jour, seules des valeurs de débit de véhicules sont disponibles. Le débit donne le nombre de véhicules par heure au point de mesure considéré (nb vhc/h). Un poin…
