  2. Overview • Background Information • Maintaining Agencies of Traffic Signals in Georgia • Regional Traffic Operations Program (RTOP) • Future Funding

  3. Background on Georgia • Population over 9.5 million • 18.3% population growth between 2000 to 2010 • 7th fastest growing state • Atlanta is the largest city • 55% of population lives in the Atlanta Region • ≈ 8500 Traffic Signals • Over 50% located in the Atlanta Region • 47% located on State Routes

  21. Communications Plan

  22. Award Winning Program • 2010 Outside the Box Award – ITS Georgia • 2010 ITS America Smart Solution Spotlight – ITS America • 2012 Outstanding Public Agency Award – ITS Georgia

  23. Spring 2012 Comparison to Baseline • During the AM/PM peaks: • Reduced number of stops by 8.3% • Reduced stopped time delay by 12% • Traffic Volume increased by 9%

  24. Project Benefit • Over the last year during AM/PM peaks: • Eliminated 1.2 million hours of delay • Saved 700,000 gallons of fuel

  25. RTOP Funding • Late start the first year – funding cut • Success in 2011 and 2012 lead to increased funding • Program now in expansion phase $8M PI 0009544 $16.25M PI 0009549 $3M PI 0009543 $10M PI 0009545 $12.75M PI 0009546 $16.25M PI 0009547 $16.25M PI 0009548
