Abstract: This project, in partnership with the Arizona Department of Transportation (ADOT), evaluates whether Arizona's pavement marking standards meet the needs of both human drivers and driver-assist vehicle technologies such as Lane Departure Warning, Lane Keeping Assistance, and Lane Centering Assistance. As camera-based systems increasingly rely on the same markings drivers use, the visibility and consistency of those markings have become critical to safe operation. This affects overall mobility, particularly at night, in adverse weather, and in worn conditions. The project covers a review of federal and ADOT marking standards alongside detection requirements gathered from vehicle-technology companies, an assessment of how Arizona's environmental stressors affect marking performance across the state's diverse climate regions, and structured interviews with peer state DOTs to document proven maintenance and assessment practices. Findings will inform updated design and installation guidelines, a performance-based assessment framework, and a cost-effective long-term maintenance strategy for ADOT.
