ABOUT US
Our Mission
The mission of the Transportation Management Association of Chester County (TMACC) is to activate, foster and facilitate cooperation between the public and private sectors of Chester County; to identify, evaluate and analyze significant transportation issues and to recommend solutions that reduce congestion and improve air quality.
Our History
TMACC was founded in May of 1992 as the Chester Valley TMA and consisted of 14 Founding Members, which include some of our current members today: Chester County Intermediate Unit, Great Valley Regional Chamber of Commerce, Krapf’s Coaches, Inc., PennState Great Valley, and Saul, Ewing, Remick & Saul. In June of 1995, the Chester Valley TMA Board of Directors changed our name to the Transportation Management Association of Chester County to better capture the members we wanted to acquire.
Today, TMACC represents the expanding region of Chester County and continues to advocate for sustainable transportation practices and connectivity. TMACC’s membership represents over 20,000 commuters in Greater Philadelphia and includes a range of organizations in engineering, planning, law, consumer goods, finance, hospitality, education and more.
