High-Tech Pavement Markers Support Autonomous Driving in Tough Conditions, Remote Areas
Oak Ridge National Laboratory
June 20, 2023
Engineers at the U.S. Department of Energy's Oak Ridge National Laboratory and Western Michigan University have enabled raised pavement markers to transmit global positioning information that improves autonomous driving in remote areas or during inclement weather. The researchers embedded low-powered sensors within the markers that send information to passing cars about road shape even when obstructions reduce the reliability of vehicle cameras or light detection and ranging (LiDAR). The technology hands over some data processing from the car's software to infrastructure, saving electric vehicle battery power and broadening driving range. The researchers said electrical vehicle navigation systems use up to 90% less power when navigating with the sensor-equipped pavement markers, compared to leading camera and LiDAR-based autonomous driving technology. ...
