Abstract

While a great deal of work on skid resistance has been conducted in Virginia over the past three decades, only within the past year has attention been given to the development of a systematic program for the identification and treatment of high of potentially high wet pavement accident sites. The purpose of this paper is to outline that program. The use of Virginia's automated accident and survey skid data files in the program is described. The site selection process utilizing these two data bases is explained as is the site review process, including the field review. The economic analysis used initially to rank sites for field review, and used again to rank sites for recommended treatments is also explained. In essence, this economic analysis involves the computation of a breakeven value considering the costs of possible site treatments versus projected savings from reductions in wet pavement accidents. As explained in the paper, in the Virginia program there is an emphasis on the use of accident data, with every effort being made to achieve the greatest total reduction in wet accidents with a given amount of funds for improvements.
