In Finland, a road weather information system was projected to yield a benefit-to-cost ratio of 5:1 by reducing annual vehicle costs, and improving motorist travel time and safety.
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. Traffic will improve because of better road conditions, in turn benefiting driving time, fuel, and the environment. The estimated cost benefits were $900K/yr in accident cost savings, $60K/yr in time cost savings, and $20K/yr for vehicle cost savings for a total of $980,000 per year. The cost-to-benefit ratio is about 1 to 5 in the Kymi road district (a typical road district in Finland).
