Speed limits of arterial highways and in the rest of the main road network

This metric is used to monitor the fulfillment of the criteria of the Decree on Arterial Roads and Railways and the realisation of a stable travel speed for long-distance traffic on arterial roads belonging to service level classes I and II in Finland. These data are part of the performance metrics of Finland’s National Transport System Plan (Liikenne 12) and primarily updated once a year. The information is produced by the Finnish Transport Infrastructure Agency. The information on this page is only available in Finnish for the time being.
