Study Title: Safety Effects of a Targeted Skid Resistance Improvement Program
Authors: Lyon and Persaud
Publication Date: JAN, 2008
Abstract: The study examined the safety impacts of improving pavement skid resistance using data from New York State. The New York Department of Transportation (NYDOT) runs a skid accident reduction program that identifies sections of pavement with a high proportion of wet-road accidents, friction-tests these locations according to ASTM E-274 using the ASTM E-501 Ribbed Tire, and treats those with both a high proportion (35-40%) of wet-road accidents and low friction numbers (<32). An empirical Bayes before after study was conducted of locations that were treated under this program. The results indicate that this can be a highly cost effect safety treatment for both intersections and road segments that warrant skid resistance improvement because of a high frequency of wet road accidents and low friction numbers.
