Benefit Summary HTML

The Colorado Department of Transportation (CDOT) is using friction sensors— electronic radars attached to the back end of fleet vehicles— to collect data on the amount of grip present on a roadway, increasing road safety and lowering costs.

The sensors relay information on pavement temperature changes, along with friction and moisture levels present on a roadway, to the Maintenance Decision Support System (MDSS) where they determine which segments of roadway need salt, liquid materials, plowing, or a combination of treatments. By mapping site-specific data, maintenance workers can focus on areas that need treatment rather than treating whole sections of roadway.
