Abstract: This paper focuses on identifying roadway locations that display high collision rates only under wet pavement condition A unique approach of screening and identifying such locations, called the continuous risk profile (CRP) method, was utilized for this analysis The CRP method was applied to over 380 miles of freeways in the San Francisco Bay Area to identify sites that display high collision rates only under wet pavement condition Twelve of the identified sites were then further investigated to determine if there are any common geometric, topographic, or site conditions that may contribute to the high collision rates under wet pavement conditions.
