Road icing is mainly caused by water accumulation on the road surface or snow falling and low temperature, and traffic accidents are easily caused only by observing and judging the ice type by a driver at the present stage. Currently, icing detection is mainly applied to airplanes, and many icing sensors for icing detection have no capability of identifying ice types, such as conductivity type, pressure difference type, radiation type and piezoelectric diaphragm type icing sensors.
