Overview

  • Background Information

  • Maintaining Agencies of Traffic Signals in Georgia

  • Regional Traffic Operations Program (RTOP)

  • Future Funding


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


Who Operates the Traffic Signals?

  • Maintaining Agencies:

    • 7 GDOT Districts

    • 54 Counties

    • 36 Cities

  • Top 5 maintaining agencies:

    • GDOT: 1536 signals

    • City of Atlanta: 975 signals

    • Gwinnett County: 674 signals

    • DeKalb County: 661 signals

    • Cobb County: 543 signals


  • Atlanta Region’s Signal Operators

  • In most major metropolitan areas:

    • State DOT manages the freeway network

    • Local agencies manage arterials

  • In Atlanta:

    • 4 GDOT Districts

    • 15 Counties

    • 22 Cities


RTOP’s Role

  • Traffic Signal Maintenance and Repair Issues

  • Regional Focus

    • Mainline Priority

    • Cross-Jurisdictional

  • Actively Manage Traffic Flow

Mission: To increase travel throughput by minimizing congestion and reducing delays along regional commuter corridors through improved signal operations.

Planned


Active Management

  • Control from a single location

  • AM Peak

    • 6 AM to 10 AM

  • PM Peak

    • 3 PM to 7 PM


Real Time Traffic Signal Adjustments


Support of Construction Activities

  • RTOP Does Not Go Away When Construction Projects Start


Use of Technology

  • Travel Time Pilot Project

  • Ethernet Over Copper – City of Atlanta

  • Ethernet Wireless

  • Non Intrusive Detection

  • Alternative Detection

  • IVDS Over Ethernet

  • IP Cameras

  • Regional Video Sharing


Traffic Responsive Operation


Communications Plan


Communications Plan


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


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%


Project Benefit

  • Over the last year during AM/PM peaks:

    • Eliminated 1.2 million hours of delay

    • Saved 700,000 gallons of fuel


RTOP Funding

  • Late start the first year – funding cut

  • Success in 2011 and 2012 lead to increased funding

  • Program now in expansion phase
