Pollution Episode Map

20 km/h speed reduction, alternating traffic, heavy goods vehicle transit restrictions... Emergency measures taken during an atmospheric pollution episode can significantly impact traffic conditions.

This is why Bison Futé, in partnership with the Central Laboratory for Air Quality Monitoring (LCSQA)—which collects this information in real time—informs you when traffic measures related to pollution peaks are in effect. By clicking on a colored department (orange or red) on the map below, the traffic measures are displayed.
