The Georgia Regional Transportation Authority (GRTA) is looking to improve mobility and reduce traffic bottlenecks in a key activity center in Atlanta. The GRTA will target one of the largest non-downtown office concentrations in the Southeast, Perimeter Center, to see if a shuttle service, a fixed, street-level or elevated transit system or other transportation alternative will improve mobility at Interstate 285 and GA 400. "We're trying to see what is the best way to get you where you're really trying to go at Perimeter Center," said Dr. Catherine L. Ross, GRTA's executive director. "Perimeter Center has four MARTA rail stops and private shuttle services operated by individual companies, but no overall system to move people around this important office, commercial and residential activity center." Carter & Burgess will conduct an alternatives analysis and environmental assessment. The cost of the study is about $2 million and is expected to take two years to complete.
