About the research


This project will mine existing National Transportation Product Evaluation Program (NTPEP) pavement marking performance data (related to pavement marking products used by local agencies) to provide guidance to local agencies. The objectives include determining pavement marking products of interest to local agencies and developing performance metrics for these products based on existing NTPEP data. A list of recommendations for future pavement marking research support to local agencies will be developed.
