This report discusses the implementation of available knowledge and points out the areas needing further study. Low skid resistance has a marked influence on accident levels at 2 types of road locations: locations where drivers are not required to take emergency action but at which friction demands may not be satisfied in wet-road conditions (a curve without adequate superelevation and with low skid resistance); locations at which conflict accidents predominate (rear-end collisions on freeways in saturation conditions, and collisions at intersections). There is general agreement on the relation between wet-road accidents and skid resistance, and on the fact that skid-resistance measurements alone are not a sufficient guide to the need for improvement and planning processes. The need is indicated for optimization of the cost benefits of skid resistance improvements. It was also recommended that the use of existing cost-effective methods for accident reduction should be encouraged by the provision of training and incentives for highway maintenance management personnel and that consideration should be given to the use of advance delineation techniques for the reduction of wet-weather accidents. Eleven areas which were identified as requiring additional research are listed.
