The TMA Group is a public-private partnership committed to providing environmentally friendly, affordable, reliable, and safe mobility options for Middle Tennesseans. Formed in 1988 as a non-profit (501c3) organization, The TMA Group was the first transportation management association in the Southeast and the 35th in the nation.

Over the years, The TMA has engaged in a number of programs and innovative research projects including: starting Tennessee’s first Emergency Ride Home program; studying global warming and the potential impact of Transportation Demand Management (TDM) measures; developing a bicycle major route plan; participating in a corridor-wide congestion management program during interstate reconstruction; performing an FTA study on corporate amenities and TDM; and conducting pilot telecommute programs.

In 1992, The TMA Group was admitted as a voting member of the Nashville Urban Area Metropolitan Planning Organization Technical Coordinating Committee. The TMA Group worked with the Tennessee Department of Transportation and the Federal Highway Administration in the development and implementation of corridor-wide congestion management measures during the widening of I-65 in both 1993 and 1997. Upon the request of TMA and Franklin, the 1997 project included Tennessee's first incident management service patrol. Major research conducted for the Federal Transit Administration in 1994 helped define the role of amenities at the workplace play in supporting transit ridership and contributed to the national Liveable Communities Movement. The TMA Group worked with the City of Franklin in the development of Franklin Transportation Operations Center. The TMA Group developed a Transportation Enhancement proposal on behalf of the City of Franklin for a pedestrian bridge over the Harpeth River to link Historic Main Street to Pinkerton Park and a major Civil War site. The bridge was completed in 1999.

Currently, The TMA Group manages a vanpool fleet, in partnership with Williamson County, the City of Franklin and the Regional Transportation Association consisting of 40+ vehicles providing mobility to commuters in nine area counties.

After five years of thorough studies with the City of Franklin, the Franklin Transit Authority’s public transportation system – the Franklin Trolleys – was launched in May 2003. The TMA Group is the manager of the system. The system was the first new transit system in the State of Tennessee since 1986 and the first in Williamson County since the mid-1980’s.

The TMA Group is leading the way in bettering the air quality of Williamson County and the surrounding region through education, programs and services. During 2004, the Clean Air Partnership of Williamson County, a public outreach initiative of The TMA Group and Williamson County Government to help combat the problems of poor air quality was launched. Currently 52 leading corporations and businesses are partners.
