Traffic status of the Métropole de Lyon – real-time availability

Real-time traffic status is a linear object that represents the traffic density measured in real time (green = fluid, orange = dense, red = loaded, black = cut road, grey = unavailable data). Traffic status is refreshed every minute.

These data are derived from information retrieved by traffic measurement sensors and are consolidated in the CRITER system (automated regulation of road traffic) of the Direction de la Cheminie du Grand Lyon.
