    1. The Role of ITS in Gwinnett County Arterial Management ITS Georgia June 25, 2009

    2. 1

    3. 2 Background Gwinnett County identified the need to expand its ITS capabilities as part of the 2001 Comprehensive Transportation Plan. Expansion of the ITS system was identified as a method of improving the safety and efficiency of the County’s road network.

    4. 3 Background Revenue from the 2001 SPLOST was designated for the design and construction of ATMS projects and the development of a modern Traffic Control Center. ATMS Projects were identified and designed following the GDOT PDP. Additional ATMS Projects were identified and funding allocated as part of the 2009 SPLOST program.

    5. 4 Background Chuck Bailey had the vision and it was up to me to make it happen.

    6. 5 Background 2001 SPLOST Projects Completed Upgrade existing CCTVs on JCB & US 29 to Domes on separate poles Peachtree Industrial Blvd SR 20 (Buford Drive) SR 124 (Scenic Hwy) Lawrenceville-Suwanee Road

    7. 6 Current Capabilities (2009) Peak Period Monitoring with existing staff 6:00 to 9:00 16:00 to 19:00 Special Event Monitoring Gwinnett Braves July 4th Signal System Communication Direct Control or Dial up Closed Loop Real time timing adjustments due to road closures, accidents, construction Timing optimization projects

    8. 7 Current Capabilities (2009) Digital Traffic Control Center 2009 NACo Achievement Award winner Redundant Paths from the TCC to GJAC and field devices

    9. 8 Current Capabilities (2009)

    10. 9 Current Capabilities (2009)

    11. 10 Current Capabilities (2009)

    12. 11 2001 SPLOST Funded ATMS Project Status Under Construction SR 120 (Pike St) Old Norcross Road SR 378 (Beaver Ruin Road) Satellite Blvd Construction funded by ARRA US 23/SR 13 Sugarloaf Pkwy Current Capabilities (2009)

    13. 12 Short Term Objectives (2009/2010) Provide selected CCTV video to TV Gwinnett during peak times Provide CCTV video on the gwinnettcounty.com website Maintain peak period monitoring and increase special event monitoring

    14. 13 Short Term Objectives (2009/2010) Add County fiber infrastructure to the 811 One-Call utility locate system Connect to E911, Fire/EMS HQ, EOC Transition to a new TCC control software for cameras that is scalable for additional ITS functions Work with GaDOT to have GCDOT video available to NaviGAtor users

    15. 14 Complete ATMS Projects currently under construction or scheduled to begin in 2009 Layer 3 Ethernet routing in the field Begin design on additional ATMS projects Expansion of field Layer 3 devices Additional redundancy Increase direct control of signal systems Higher communication speeds Able to implement incident plans Short Term Objectives (2009/2010)

    16. 15 Begin digital migration for Legacy systems Additional Traveler information initiatives Short Term Objectives (2009/2010)

    17. 16 Short Term Objectives (2009/2010)

    18. 17 Short Term Objectives (2009/2010)

    19. 18 Expand monitoring to cover 06:00 to 19:00 M-F and add’l special events as needed Complete digital migration to IP devices Create the “Nervous System” setup Field devices notify TCC operators with critical alarms Improved response by technicians Faster response = reduced delays Long Term Objectives (2015)

    20. 19 Complete 2009 SPLOST ATMS projects Evaluate possibilities with wireless signal communications Point to point Point to multi-point Cellular 4G network Evaluate possibilities with IP over copper Long Term Objectives (2015)

    21. 20 Add Dynamic Message Signs Add Full-Time TCC Staff Longer Term Objectives (2015+)

    22. 21 Long Term Objectives (2015)

    23. 22 2015 ATMS and Signal Map 2009 = 646 2010 = ~ 665 2015 = ~ 700 Long Term Objectives (2015)

    24. 23 Conclusions Significant progress has been made since 2001, but expansion of the arterial ITS network and services is required to meet citizens’ need for information. Additional funding and dedicated staff will be necessary to maintain the ITS network and facilitate expansion of traveler information services.
