This summary describes the solution as well as opportunities for expansion into the broader context of rural ITS. Ice tends to form on bridges and overpasses before it does on other portions of the roadway. Given that the main roadway may not be icy, drivers often do not anticipate icy conditions on bridges, etc., and are therefore not prepared. This simple solution equips those sites most susceptible to icing with detectors connected locally to a device that warns drivers to slow down and use caution on the icy surface
