Ontario's Wet Pavement Accident Reduction Program

Source

Ontario's approach to the identification and treatment of black spot highway locations is presented. Highway locations with an excessive rate of wet pavement accidents are identified and ranked utilizing Ontario Ministry of Transportation and Communications computerized accident data files. Criteria for site selection, procedures for subsequent site investigation, and selection of appropriate remedial measures are outlined and discussed.

Rehabilitation of pavements with low friction levels, and experiencing a high rate of wet pavement collisions, has resulted in substantial reductions in accidents. Collision data before and after treatment at various sites are presented.

This paper provides design and performance information on modified bituminous surface course mixes currently used by the Ministry. Such mixes maintain better surface textures and provide longer lasting skid resistance characteristics. These mixes are used for black spot treatments, and in new surface construction on main highways.
