Abstract
Instrumentation and procedures for determining pavement skid resistance requirements at intersections and other braking sites are described, and they can be used by highway agencies (1) to determine the relative skid-resistance requirements (normal, intermediate, or high) for specific braking sites, and (2) to study existing problem sites in terms of probable causes of accidents and the influence of proposed corrective measures. Additional research and field evaluation efforts are necessary to further develop and verify procedures for determining skid-resistance requirements at curves and other types of sites in a more precise manner.
