Virginia's VTI advances automated truck safety with new attenuation technology

The Northern Virginia Transportation Authority's Transportation Technology Committee meeting on April 13, 2022, highlighted significant advancements in automated transportation technology, particularly focusing on automated truck-mounted attenuators. These devices are designed to enhance safety in work zones by acting as crash cushions to protect workers from errant vehicles. The committee discussed the development of an automated version that can follow a lead vehicle, reducing the risk to operators while maintaining operational efficiency.

The meeting also addressed ongoing research initiatives by the Federal Highway Administration (FHWA), which is exploring cooperative automation and connectivity in transportation. This research, known as the Karma program, is being conducted in collaboration with various states, including Maryland and Florida.

Additionally, the committee noted that the U.S. Department of Transportation (USDOT) has awarded grants to the Virginia Transportation Institute (VTI) for two projects focused on automated driving systems (ADS). One project aims to facilitate a coast-to-coast trip with an automated truck, although the timeline for this initiative has been impacted by the COVID-19 pandemic. The second project will investigate how automated systems respond to complex driving scenarios, including the challenges faced by human flaggers in work zones.

The discussions underscored the importance of continued innovation in transportation technology and its potential to improve safety and efficiency on Virginia's roads. The committee expressed enthusiasm for these developments and encouraged further collaboration and research in the field.
