Adapting Pavement Markings to Support Highway Safety and Automated Vehicle Technologies
For the foreseeable future, there will be a mixed fleet of vehicles operating on the world's highways. Human-led vehicles will slowly give way to partial-to-full automated vehicles operating in expanding conditions (extended operation design domains). How can agencies prepare for this trend while providing safe and efficient travel for today's drivers?
Pavement markings have been used for over 100 years to provide delineation of the travel path. They were first painted lines on the road, only visible during the daytime conditions. Then retro reflective optics were included to increase their visibility at night. More recently, specialized markings have been used to increase visibility during wet night-time conditions. The research literature includes ample documentation of how advancements in markings have proven safety benefits. This webinar will start with a summary of the key research findings related to the benefits of pavement markings for human-led vehicles.
More recently, as automated vehicle technologies have been deployed, the most commonly referenced highway infrastructure element that is needed to support their deployment is "better" pavement markings-although there is typically very little detail provided to understand what "better" means. Through several years of research and engagements with the automotive industry, three areas have emerged that describe how pavement markings can support automated vehicle technology deployment: greater uniformity, higher quality, and established maintenance criteria. The second part of the webinar will include specific examples of how agencies can prepare their roadways for automated vehicle technologies while increasing safety for human-led vehicles.
