Effectiveness of Automated Pavement Restriping Systems - Phase 2

The Kansas Department of Transportation (KDOT) is responsible for maintaining the pavement markings on its 10,291-mile roadway network. The centerline markings, lane markings, and edge line markings are applied annually using waterborne paint from six restriping trucks, one for each KDOT district. These vehicles are durable pieces of equipment and are expected to last 20+ years; currently these vehicles are each less than 5 years old. While having newer vehicles is generally a good thing, as new technologies become standard equipment on newer models it can be a challenge to justify upgrading existing vehicles until the next replacement cycle, meaning new innovations might not be implemented until the next equipment replacement cycle. One paint crew (District 5) has been selected to receive two upgraded vehicles (layout truck and striping truck) in 2023 to increase the productivity of the pavement restriping process. Specifically, these upgraded vehicles are expected to a) speed up the marking layout process, and b) eliminate the need for one of the crew members in the striping truck. After the finding of the phase one report against adoption of the automated pavement restriping system on a purely economic basis, the second phase of this project is being proposed to run during CY 2023. The automated painting system has been delivered to District 5’s paint crew since the conclusion of phase one, so this phase will aim to evaluate that system to determine the accuracy and effectiveness of the work produced by it. This evaluation would use field data collection to determine if the system results in a similar result as if an experienced KDOT field employee were doing the restriping. Together, this will serve to improve KDOT’s understanding of automated paint restriping systems to determine if wider implementation is warranted systemwide and create a more accurate cost savings recommendation.
