Evolving truck-platooning techniques are paving unique paths
to high-level commercial vehicle autonomy.

benefits: an estimated 30% or more reduction in
operating cost per mile, 8% reduction in fuel expense,
increase in freight density of 2x per lane and annual
CO2 emissions cuts of 41 metric tons per tractor.
Locomation believes human-guided autonomous
convoys provide a " stable development path " for
higher levels of automation moving forward.
Still, truck platooning is not without its own
hazards.
Locomation
" We are tantalizingly close, " a recent blog post by
Locomation asserted regarding true driverless vehicles
navigating public roadways. " But the challenges that
remain on the pathway to commercialization will keep
the dream at bay for some time to come. " Instead,
the Pittsburgh-based tech company's approach to
autonomy keeps a human firmly seated in the cab -
at least in the lead vehicle of a truck platoon.
Locomation's proprietary Autonomous Relay
Convoying (ARC) technology has an AI-controlled
follower truck that uses its own perception and
information exchanged over dedicated short-range
inter-vehicle communication (DSRC) to follow the
human-driven leader tractor-trailer. The follower rig
remains aware of its surroundings and is cognizant
of potential threats, according to Locomation, but it
leaves most of the high-level driving decisions to the
human and is only concerned with mimicking the
maneuvers of the lead truck.
Platoons employing this approach are logging
miles and collecting data on different stretches
of highway across the U.S. The company recently
completed a pilot project operating on Interstate 84
between Nampa, Idaho, and Portland, Oregon. The
challenging stretch, which includes steep grades,
tricky curves and gusty winds, allowed engineers to
observe how the system would have performed on its
own. " We are focusing on the parts of full autonomy
that can be commercialized successfully today, leaving
the parts that require further development and validation for tomorrow, " the company said.
Due to aerodynamic-drag improvements and
precise control of the vehicle by the autonomous
driving system, ARC is expected to provide several
With Locomation's proprietary Autonomous Relay Convoying technology,
an AI-controlled follower tractor-trailer uses its own perception and information exchanged over DSRC to mimic the human-driven leader rig.
