In Finland, a road weather information system was estimated to improve response times for road treatments, decrease the duration of slippery road conditions by 10 to 30 minutes, and eliminate 3 to 17 percent of crashes.
The duration of slippery road condition has been estimated to shorten 10-30 minutes per de-icing activity, which decreases the chance for accidents caused by slipperiness. Improvement in response to maintenance activities would decrease accidents 3 to 17 percent depending on the district and the winter.
