Black ice on the road can be a killer. This design helps predict when it might occur.

Vehicle manufacturers strive to make our driving experience ever more comfortable. Such items as ride control, power steering, electronic engine management, and air-conditioning now appear as standard fit on many vehicles. As a result we become more and more detached from the outside environment.

One of the most important considerations would seem to be the quality of the contact between tires and road surface, a factor that directly affects our style of driving. We generally notice if the road is wet, muddy or covered in leaves and take appropriate precautions, but we can’t see black ice. For this we need an external temperature sensor, warning us when the likely conditions for ice on the road are developing – the answer is this Vehicle Frost Box project!
