What is Truck Platooning?
Level 2 truck platooning extends radar and vehicle-to-vehicle, communications-based, cooperative-adaptive cruise control using precise automated lateral and longitudinal vehicle control to maintain a tight formation of vehicles with short following distances. A manually driven truck leads a platoon, allowing the driver(s) of the following truck(s) to disengage from driving tasks and monitor system performance. Level 1 truck platooning has demonstrated the potential for significant fuel savings, enhanced mobility and associated emissions reductions from platooning vehicles. Level 2 automation may increase these benefits while reducing driver workload and increasing safety.

Why Truck Platooning?
Besides driver compensation, the largest oper-
ating expense for a line-haul truck is fuel. At
65 miles per hour, each truck expends about

COMMERCIAL TRUCK PLATOONING: LEVEL 2 AUTOMATION (PHASE 1)
Project Partnerships and Focus
The research team represents a public-private
partnership (PPP) of government agencies,
national labs, truck manufacturers and equip-
ment suppliers, many of which have com-
mitted in-kind resources such as equipment,
engineeringservices,intellectualpropertyand
funding. The project focuses on the feasibility
ofdeployingtwo-vehicletruckplatoonsutiliz-
ing Level 2 automation on specific corridors
in Texas within 5 to 10 years.

TRUCK PLATOONING BENEFITS
SAFETY.
By reducing the
number of drivers
making decisions,
the incidence of driver error
decreases, thus increasing
roadway safety for others.
ECONOMICAL.
Projected fuel
savings of around
12 percent can drive
transportation costs down, and
that results in reduced prices at
the grocery store.
ENVIRONMENTAL.

2. Project Overview
With funding from TxDOT’s innovative
research program and PPPs, the Texas A&M
TransportationInstitute(TTI)createdafirst-
of-its-kind comprehensive freight platooning
demonstration in Texas. Building upon
other platooning research, the TTI team will
strive to demonstrate the potential safety and
mobility benefits, fuel savings, and emission
reductionspossiblebyextendingvehicleauto-
mation to freight truck platoons. The project
is planned in three phases:
• Phase1(completed):Conductafeasibil-
ity planning study and proof-of-concept
demonstration.
• Phase2(ongoing):Developtheconcept
of operations and requirements for the
design and vehicle system; enhance
system functionality and reliability; and
developthePhase3implementationplan
and deployment guidance.
• Phase3(planned):Deployacommercial
truck-platooning application in Texas.
Project Outcome
In Phase 1, the TTI team documented les-
sons learned from past platooning projects;
identified potential regulatory or legislative
roadblocks to introducing platooning into
commercial fleet operations; and explored
potential implementation scenarios given
the existing infrastructure and operational
environment.OnJuly22,2016,theTTIteam
successfullydemonstratedaproof-of-concept
of the platooning technology.
BegunNovember1,2016,Phase2willtransi-
tion the proof-of-concept to a plan for safely,
reliablydeployingplatooningonacommercial
operator’s fleet in Phase 3. To demonstrate
real-world viability, the TTI-led team will
test the system in one or more field pilot dem-
onstrations and/or in controlled, open-road
scenarios. Researchers will assess the impact
of platooning on TxDOT’s infrastructure
and operations by researching critical issues
likegeometricand trafficoperationsimpacts,

The Texas A&M Transportation
Institute, established in 1950, seeks
solutions to the problems and chal-
lenges facing all modes of transpor-
tation — surface, air, pipeline, water
and rail. The Institute works with
nearly 200 sponsors in the United
States and abroad at all levels of
government and in the private sector
and is recognized as one of the finest
higher-education-affiliated transpor-
tation research agencies in the nation.
TTI has saved the state and nation
billions of dollars through strategies
and products developed through its
research program. TTI research has
a proven impact — resulting in lives,
time and resources saved.
About TTI
ing a Phase 3 deployment plan, the team will
also develop near-term guidance for TxDOT
and other stakeholders to prepare Texas for
deploying truck platooning on key facilities
across the TxDOT freight network.
