19Measurement of Dry Asphalt Road Surface Friction Using Hyperspectral Images
19.1Introduction
A vehicle which is able to drive on a road must have adequate surface friction in the contact area between the tires and the road surface, so that loss of driving control does not occur in situations normally expected to be safe and comfortable (Anderson and Henry 1979; Heaton et al. 1990; Liu et al. 2003a, 2003b). Thereby, the Skid Accident Reduction Program issued by the Federal Highway Administration (FHWA 1980) encouraged each state highway agency to minimize skidding accidents (especially under wet weather) by identifying and correcting sections of roadway with high or potentially high skid accident incidence and ensuring that new surfaces ...
