Abstract :
A road surface recognition method at fixed positions on the road is presented, with which a light source and a CCD camera are employed. The method has a certain optical configuration and two factors: road gloss and spatial frequency spectra of the road surface. Experimental results show that the road surface conditions that were expected to be discriminated in cold districts were recognized. Therefore, the method should be very useful for a traffic information system
