Virginia Tech Transportation Institute researchers and their companions just lately put an autonomous Ford F-150 by way of a sequence of driving eventualities associated to public security on the 395 specific lanes in Arlington, Va.
Approaching a driver throughout a site visitors cease is often a second of heightened consciousness for legislation enforcement officers.

However what occurs when car that simply got here to a halt on the freeway shoulder has no driver?
This was simply considered one of quite a few autonomous vehicle eventualities Virginia Tech Transportation Institute (VTTI) researchers have been serving to develop solutions for in the course of the previous 4 years.
“We have now a sequence of shows with the potential to work together with a police officer, together with with the ability to contact a fleet supervisor and speak to a human to assist resolve the problem,” mentioned Mike Mollenhauer, division director of expertise implementation at VTTI.
“We’re attempting to determine how they’ll do what they want performed and do it safely, in addition to a number of the points associated to how the car goes to establish somebody who’s or is just not an authority and what authority they need to have over the car.”
The autonomous expertise was considered one of a number of feats on show in the course of the Safely Working ADS (Autonomous Driving Techniques) in Difficult Dynamic Eventualities undertaking demonstration in Arlington this week. The occasion featured VTTI’s Stage 4 autonomous Ford F-150 shifting by way of quite a few public security interactions on the Interstate 395 specific lanes.
“Stage 4 implies that inside a sure spectrum of operational designs — equivalent to a sure sort of roadway and in sure climate circumstances — the car ought to have the ability to function itself with out the expectation of a driver taking up,” Mollenhauer mentioned.
“Proper now, from a driver functionality perspective, you possibly can consider it as form of like a toddler. It may well do a whole lot of issues, however it may possibly additionally get itself into hassle as a result of it doesn’t have a whole lot of expertise but.”
To assist acquire that have, the truck was tasked with navigating 18 conditions, together with interacting with roadside employees, first responders, and different drivers. The parameters for the trials have been developed in partnership with
- Virginia Division of Transportation
- Crash Avoidance Metrics Companions LLC, a consortium of car producers consisting of Ford, GM, Mercedes-Benz, and Nissan
- Transurban North America, a world toll highway firm that oversees the Interstate 495, 95, and 395 specific lanes and incorporates good expertise in roadways
“By tasks like this, we’re hoping to take the ‘ominous out of autonomous,’” mentioned Joe McLaine, security engineer for Normal Motors and chairman of Crash Avoidance Metrics Companions LLC.
“We need to let of us know — the driving public, the using public, and people equivalent to first responders and emergency companies who will proceed to work together with these car techniques within the not too distant future — we need to let all of them know that the automakers, the OEMs [original equipment manufacturers] creating and deploying this expertise, together with trusted companions like VTTI are taking all of those eventualities into consideration from the very get-go.”

Together with site visitors stops, different eventualities included
- Detecting and maneuvering round out-of-sight hazards by speaking with roadway expertise
- Navigating round first responders and work zones, together with detecting lane change prompts and executing the merge.
- Responding to emergency autos
- Figuring out and following hand indicators offered by a authority the car acknowledges
- Utilizing real-time pace and distance data from the roadway with the intention to create tight car formations
The demonstration was partly the results of a $7.5 million U.S. Division of Transportation and Federal Freeway Administration grant, which the undertaking companions and VTTI obtained in 2019. Since then, the VTTI analysis staff has labored with its collaborators to not solely develop the undertaking parameters but additionally to outfit the 2022 hybrid truck with expertise that may require as a lot as 120 amps to function.
Mollenhauer mentioned that whereas the undertaking has made nice progress, it additionally has revealed many unanswered questions associated to public security and autonomous autos. These are areas VTTI plans to proceed to work with private and non-private companions to deal with by way of its analysis.
“Which means increasing on a number of the capabilities we’ve developed and maybe constructing on a few of them by actually getting on the market and having the those that do that work – fireplace, EMS [emergency medical services], legislation enforcement – interacting with and attempting out these autos to provide us suggestions,” Mollenhauer mentioned.
