Abstract:Black ice is a thin coating of glazed ice on roadways or other transportation surfaces. Black
ice has identical appearance with black pavement and wet road, and it often forms during calm
weather. It is highly transparent and thus difficult to see. Black ice usually forms at night or early
morning, first on bridges and overpasses (due to their elevated nature and being exposed on all
sides), then on the roads as temperatures continue to drop.
In this project, we develop a prototype decision support system (DSS) to predict and detect
black ice formation and pin point dangerous road sections. To reduce accidents caused by back
ice, a wireless controlled module control would activate ice-warning and lane-closure signals and
lights remotely. The DSS will help Oklahoma Department of Transportation (ODOT) and Oklahoma
Department of Emergency Management (OEM) make prompt and effective decisions to reduce the
number of traffic accidents caused by ice.
