Abstract

The methods described herein identify highway sections that could be suspected of having a worsening accident experience. In their general application they merely identify the location, using accident reports, where an agency can search through the "exposure hyperspace" for specific changes in exposure factors to explain the cause of an apparent worsening accident experience. The application of the methods, of interest in the subject of this paper, is directed toward a worsening wet pavement accident experience. The exposure factor suspected of undergoing a change is the wet pavement skid resistance. The basis of accident report form. With minor changes the accident data classifications illustrated can be modified for use by other agencies having slightly differing accident report forms.
