The Sundarban
The pair of semi vehicles cruising down Interstate 70 between Columbus, Ohio, and Indianapolis also can fair seem unremarkable at the beginning look. Nevertheless these rigs are share of a groundbreaking pilot venture that will reshape The USA’s freight industry.
Launched in April through a joint initiative between the Ohio and Indiana Departments of Transportation (DOTs), the venture tests semi-self reliant “platooning” technology, through which a lead truck operated by a human driver is linked to a follower truck by means of encrypted, militia-grade communications. Alerts from the lead truck management the follower truck’s steering, acceleration, and braking; in essence, the follower truck mimics what the lead truck does. With one driver effectively working two vehicles, the system extends fleet capability with out doubling headcount. Alongside with addressing the nation’s continual truck driver shortage, It’ll also elevate security and pork up fuel effectivity.

“Right here is ready reimagining the future of transportation in our space,” says Carve Hegemier, managing director for infrastructure and technology at DriveOhio, a dapper mobility initiative inside the Ohio DOT. “By taking part across command strains and sectors, we’re paving the formula for smarter, safer, and further efficient freight dash.”
What’s truck platooning?
For the pilot venture, Kratos Defense, a San Diego–essentially based defense contractor identified for its self reliant militia programs, adapted its battlefield car-following technology for civilian consume. The vehicles are operated by EASE Logistics, in Dublin, Ohio.
“We’re no longer changing drivers—we’re extending their attain.”

Kratos’s system will seemingly be retrofitted to existing vehicles and is designed to be tough in excessive-interference environments. It uses dual-channel, frequency-hopping communications and 256-bit AES encryption. The vehicles can switch between two radio frequencies—915 megahertz and 2.4 gigahertz—to take care of a exact connection at the same time as they roll through digital tollbooths, which mostly consume 915 MHz.
“There’s no Wi-Fi, no mobile, no Bluetooth,” says Maynard Component, vp of business model at Kratos. “Right a enlighten car-to-car link with attractive fallback if one frequency turns into unreliable.”
The tight coordination between the vehicles improves security by serving to to dampen the stop-and-tear shockwaves that can lead to accidents. The follower truck also uses as much as 10 percent much less fuel by staying in the low-tension wake of the lead truck, while the lead truck’s fuel financial system improves by just a few percent in consequence of it experiences much less turbulence at its rear, in response to researchers.
In the one-year Ohio-Indiana pilot, the follower truck entails a human backup driver. Component says that the system can toughen backup drivers who don’t occupy industrial driver’s licenses; the eventual blueprint is to manufacture no longer occupy any driver in the 2nd car. Alternatively, if both drivers are qualified, they can switch areas when the lead driver gets drained.
“At the halt of the day, we’re no longer changing drivers—we’re extending their attain,” Component says. “We’re building a future where technology supports the personnel as an alternate of sidelining it.”
Professionals and cons of truck platooning
If platooning turns into frequent, trucking corporations would possibly perchance well establish rather a lot of money. A 2021 U.S. Division of Vitality see on truck platooning found that nationwide spontaneous platooning—where vehicles from assorted locations stumble upon every other on the road and wirelessly pair up while they’re headed in the identical route—would possibly perchance well establish nearly US $1 billion a year in fuel, says Mohamadhossein Noruzoliaee, an assistant professor of civil engineering at the College of Texas Rio Grande Valley and coauthor of the see. “It also increases road capability by about 8 percent, doubtlessly heading off $4.8 billion in infrastructure growth charges,” Noruzoliaee says. And platooning vehicles’ capability to take care of short following distances permits extra vehicles to jog on a given stretch of roadway.
In the Ohio–Indiana pilot venture, the 2nd truck will seemingly be as shut as 30 meters at the relieve of the lead truck—remarkable nearer than a human driver would possibly perchance well safely predicament up. That’s in consequence of the follower truck can react nearly instantaneously if the lead truck brakes . On closed tracks and in wind tunnel tests, vehicles were spaced as puny as 4 meters apart. Nevertheless on public roads, command rules require remarkable bigger distances.

Noruzoliaee warns a proliferation of closely spaced platooned vehicles would possibly perchance well tear up road set on. “This would possibly perchance occasionally perchance interpret restricting platooning on definite roads—treasure native streets or bridges—where pavement wasn’t designed for these load patterns,” he says. “Mutter DOTs can occupy to analyze these substitute-offs when planning for platooning at scale.”
And despite the system’s sophistication, Noruzoliaee cautions that autonomy in the follower truck stays a piece in growth. “This technology can decrease cognitive load and fatigue for the follower,” he says, nonetheless the human driver in the follower truck can occupy to live alert. City environments pose particular challenges. Passenger vehicles and web stutter web stutter visitors indicators can break up truck platoons, forcing the truck pairs to reform. And that in flip takes time and reduces fuel savings.
Still, the retrofit-prepared nature of the Kratos system can occupy to get hang of it appealing to fleet operators. Recent capabilities—akin to permitting the lead and follower vehicles to regulate positions—would possibly perchance well get hang of platooning remarkable extra versatile and commercially viable.
As trying out continues along the I-70 hall, the familiar enlighten of these developed vehicles’ engines would possibly perchance well signal a functional, incremental course to freight automation—particularly when put next with the extra formidable vision of fully self reliant vehicles, treasure these no longer too prolonged in the past launched by Pittsburgh-essentially based Aurora Innovation.
Aurora’s self-driving vehicles, which started shuttling between Dallas and Houston in April, depend on AI, sensor fusion, and staunch-time resolution-making to navigate highways with out human enter. Nevertheless despite swiftly growth, fully self reliant vehicles smooth face necessary hurdles—regulatory,
