This project involves an evaluation of the potential safety impacts of inlaid pavement markings on I-40 and I-17 in northern Arizona using the Empirical Bayes (EB) methodology. Inlaid pavement markings are designed to better withstand snow plow activities and maintain their retroreflectivity better than standard pavement markings. The project entails collecting and analyzing crash, geometric, and environmental data for both treatment sites and control sites. Statistical software will be utilized to develop safety performance functions (SPFs) for use during the EB analysis, and the potential safety impacts of the inlaid pavement markings will be estimated.
