There is disclosed a method and system for classifying road surface conditions. In an aspect, the method comprises: acquiring a digital image of a road surface at a given location and time; processing the acquired digital image to generate one or more feature vectors for classifying winter road surface conditions; acquiring values for auxiliary data to create feature vectors that enhance classification of the winter road surface conditions; and based on a comparison of the feature vectors to models in a classification knowledge database, classifying the road surface condition at the given location and time of the acquired digital image. In an embodiment, the method further comprises collecting classified road surface condition information acquired from a plurality of vehicles travelling over one or more roads; and mapping the classified winter road surface conditions for the one or more roads on a graphical display of a geographic region.
