Statewide Pavement Marking Condition Assessment Program

New driver-assist vehicle technologies—such as lane departure warnings, lane-centering systems, and lane-keep-assist systems—rely on pavement striping to function safely and effectively. Therefore, if these systems cannot detect pavement markings due to rain, snow, dust, or roadway damage, they may not operate correctly. Using retroreflective raised pavement markers (RRPM) is one solution to help maintain the visibility of pavement striping under these conditions, but there are tradeoffs. For instance, vehicle technology companies report that RRPMs are effective in helping their systems work, yet deployment is inconsistent throughout many states due to the high expense of installation and maintenance. This study would help Arizona Department of Transportation's (ADOT’s) Traffic Engineering Group determine appropriate design and installation guidelines for roadway striping to facilitate the use of new driver-assist vehicle technologies and develop a long-term striping maintenance plan that supports both legacy users and new technology, fine-tune striping assessment programs to optimize where and when new roadway striping should be implemented, and determine how best to inventory the striping’s current condition in order to prioritize striping maintenance activities. This research would then help provide the basis for a statewide system to make sure all Arizona roadways have pavement markings that support and perform at the levels needed for both human drivers and driver-assist vehicle technologies.
