Smart Roads would help drivers in several ways.

1) Heated Pavement would melt the snow and ice, thus reducing the risks and saving millions of dollars each year in snow removal and salting.
2) Phosporescent Pavement would help see the road at night and in fog.
3) Embedded sensors would detect congestion as well as stopped vehicules. A vehicule that is stopped for some time would tragger a response from cameras and emergency crews.
