Abstract:

Thirty-six highway control sections were analyzed for the effectiveness of renewal of surface friction. After elimination of sections serving as links for incomplete interstate routes and of sections requiring upgrading, 23 sections remained. A criterion was developed to estimate a normal number of wet road accidents and hence the potential accident reduction by friction renewal. Neither the ratio of wet weather accident rates to total accident rates nor surface friction (SN sub-40) are adequate to define a section that will benefit from treatment. The cost per lane mile of wet weather accidents along with the above indices identifies sections warranting detailed study. Several control sections received seal coats in 1972, and the 1973 wet weather accident reductions proved the cost effectiveness of the treatment and tended to confirm the estimating criterion. In some cases, the entire cost of treatment was recovered in accident savings in the first year. It is recommended that benefit/cost analyses be used to assist in defining priorities for treatment of wet weather accident prone sections.
