stations are partially operating near Knoxville, TN, as part of a
project by the Department of Energy's Oak Ridge National Laboratory
and the University of Tennessee.
The goal: To
determine the effects of emissions on the environment by monitoring
the estimated 25,000 trucks that pass Knoxville each day.
Directed Research and Development program, funded by DOE, provided
money. Tennessee's State Partnership Program also financed acquisition
and installation of two meteorological towers. Researchers are seeking
additional funding to continue the project and to increase the scope
The fully operational
facility at Watt Road and I-40 would create a "world-class field
lab devoted to answering a multitude of questions," according
to an Oak Ridge press release.
to determine, for example, whether the stricter emission regulations
for trucks are achieving actual benefits to the environment,"
said Ralph McGill, who heads the project and is a researcher in Oak
Ridge National Laboratory's Engineering Science and Technology Division.
immediate future, though, we're hoping to learn more about truck emissions
during different operating conditions, all remotely so we won't interfere
with traffic flow."
The field laboratory
would extend 2.5 miles eastward along the valley from the Watt Road-Interstate
40 interchange to a weigh station at the top of a ridge. This section
of the interstate is a heavily traveled road where three major interstate
highways converge on a 20-mile stretch through Knoxville.
The area of the
field lab is also home to three large truckstops, a trucking company
terminal and other trucking industry-related facilities.
In addition to
the two existing meteorological towers, researchers plan to install
equipment to measure nitrogen oxide and particulate matter emissions
as trucks pass.
