• Abstract:
  The evaluation of pavement marking materials primarily relies on their retroreflectivity (RL) — a measure of how effectively they reflect vehicle headlights back toward the driver. State DOTs typically contract private firms to measure RL, often without accurate records of when markings were installed or restriped. Additionally, establishing the statistical relationship between RL and roadway safety demands rigorous data preparation, roadway segmentation, and reasonable assumptions to predict and assign RL values to individual road segments. Therefore, to promote the broader application of RL as a crucial indicator of road safety, it is essential to develop a robust approach that integrates RL prediction models to analyze its impact on crashes.
