Abstract:Besides driver compensation, the largest
operating expense for a line-haul truck is the
cost of fuel. At 65 mph, each truck expends about
65 percent of its fuel consumption to overcome
the effects of aerodynamic drag. Many of the
large and small fleet operators are currently
using a variety of different techniques and
technologies to achieve a 1 or 2 percent fuel
efficiency gain. However, research suggests that
platooning technology can provide a 5 to
20 percent fuel savings, depending on the gap,
speed, number of vehicles, and location of a
vehicle within a platoon. Platooning also offers
other benefits, such as emission reduction,
additional vehicle safety features, and increased
highway throughput, just to name a few.
Level 2 truck platooning is an extension of
cooperative adaptive cruise control that uses
automated lateral and longitudinal vehicle
control, while maintaining a tight formation of
vehicles with short following distances. A
platoon is led by a manually driven truck and
allows the drivers of the following truck(s) to
disengage from their driving tasks and monitor
the system performance. Driving in a platoon
formation has demonstrated the potential for
significant fuel savings benefits and associated
reductions in emissions from the vehicles within
the platoon.
Through this project, the Texas Department of
Transportation (TxDOT) funded the creation of a
comprehensive truck platooning demonstration
in Texas. The focus was on the feasibility of
deploying two-vehicle truck platoons on specific
corridors in Texas within 5 to 10 years. The
project brought together major partners,
including government agencies, national labs,
truck manufacturers, and equipment suppliers,
all of which have committed resources in terms
of in-kind matching of equipment, engineering
services, and intellectual property.
