To Build Better Roads and Keep Highway Workers Safe, Minnesota Looks to Autonomous Technology

Two innovative projects in Minnesota are leveraging autonomous technology to enhance road safety and longevity. The first project involves the use of robots for non-destructive pavement density testing, aiming to extend the lifespan of roads by ensuring correct asphalt density during construction. Researchers have developed transportable robots equipped with ground-penetrating radar (GPR), tested at the MnROAD facility, which demonstrated promising accuracy and potential for scalability. The second project focuses on developing self-driving trucks with mounted attenuators to protect highway workers in short-term work zones. This system features an autonomous following vehicle to reduce the risk to human drivers in hazardous positions. Both projects were discussed in a recent CTS webinar, highlighting ongoing efforts to refine these technologies for future deployment.
