Abstract
A road data apparatus is disclosed that predicts road conditions comprising a land surface data generator which derives a land surface data output from a plurality of current and forecast weather and location data, said current and forecast weather and location data comprising surface temperature, subsurface temperature, and precipitation depth, a pavement data generator which derives a road temperature and a road condition from said land surface data output and a plurality of pavement generator input data, said plurality of pavement generator input data comprising road layer data; and a roadway status indicator generator which derives a roadway status indicator from said road temperature, road condition and precipitation data. In one embodiment, the roadway status indicator is communicated to an end user through a distribution network.
