Winter in Iowa often means snow and ice, making getting around by vehicle a little tricky. The Iowa Department of Transportation is using more data than ever to find better, more effective ways to treat roads, helping drivers get around more safely and easily.
One of the most critical data points we collect is pavement temperature. Tina Greenfield from the Iowa DOT’s Maintenance Bureau, says, “As you might expect if pavement temperatures are very cold, precipitation and moisture can freeze on the roads causing our treatment options to be different than when pavement temperatures are warmer. Having this accurate data guides our winter operations.”
