Automation of the Schonfeld method for highway surface texture classification. Paper prepared for the 55th Annual Meeting of the Transportation Research Board TRB, Washington, January 1976.

The research involved development of a system for measurement and automatic classification of pavement surface textures properties in accordance with the Schonfeld method. Electronic stereo-photogrammetric techniques were adapted to obtain digital data describing the surface from stereo-photographs. Algorithms were then developed to process this data on a computer and classify the surface texture automatically.
