Metro Atlanta's Cobb County Doubles Use of SCATS Adaptive Signal Control System, Awards TransCore Deployment Contract
ATLANTA --(Business Wire)--
was selected by Cobb
County Department of Transportation to expand its SCATS
adaptive traffic signal control technology with an additional 75
intersections, nearly doubling its use of the technology and making it
the second largest deployment in the United States. The first phase of
26 intersections in the Town Center area on Cobb Parkway are now in
operation with the remaining intersections along Barrett Parkway,
Chastain Road, and McCollum Parkway expected to be fully operational by
Cobb County, located in the northwest portion of metropolitan Atlanta,
first installed adaptive signal control technology in 2006 along Cobb
Parkway (US 41) and the Cumberland Galleria area surrounding the
I-75/I-285 interchange. Now, in an effort to accelerate mobility in the
Northwest Corridor along US 41, I-75 and I-575, Cobb County will expand
the system's use.
The Northwest Corridor is one of the most congested areas in the
metropolitan region. US 41 and I-75 experience heavy traffic and delays
on a daily basis. The corridor struggles with varying traffic congestion
due to commutes to freeway interchanges, travel to regional shopping
malls, trips to local businesses and commercial districts, and Kennesaw
State University traffic, one of the fastest growing universities in the
Georgia University system.
An intelligent transportation system with adaptive capabilities can
respond to traffic patterns as they occur and reduce choke points in the
county's roadway network and subsequently reduce vehicle emissions, fuel
consumption, and travel times.
Tim Fischer, TransCore's vice president for the southeast region, added,
"What makes the SCATS adaptive system appealing is that each corridor
can be configured differently versus using the traditional time-based,
or actuated signal controls. Other systems don't have this level of
configurability or flexibility."
About SCATS Adaptive Signal Control Systems
The adaptive traffic control system known as SCATS
(Sydney Coordinated Adaptive Traffic System originally developed for
Sydney Australia by the Roads and Transport Authority) operates in
real-time to adjust signal timing in response to changes in traffic
demand and provides immediate and historical traffic information for
Cobb County traffic engineers.
SCATS is currently one of the most widely used adaptive traffic control
systems around the world controlling more than 30,000 intersections
globally and more than 1,000 intersections in the United States.
In the United States, many SCATS projects have provided marked
improvement in congestion mitigation:
Outside San Diego in Chula Vista, Calif., delays were reduced by 45
In Menlo Park, Calif., bordering Palo Alto (News - Alert) and Stanford University,
travel time was reduced up to 25 percent and delays were reduced by an
extraordinary 70 percent. In October, San Jose expanded the system to
an additional 50 intersections in Silicon Valley.
The City of Santa Rosa in the heart of Sonoma Valley saw an average
reduction in travel time by 32 percent.
