Current Coverage - Atlanta Added I-675 230 +/- miles 550+ cameras 110+ signs 165 ramps
Current Coverage - Statewide I-475 in Macon City of Macon Hurricane Evac Dalton area CMS Adel area CMS 8 other scattered CMS (weigh sta)
New System Enhancements
Addition of INRIX data Entire length of I-95 in Georgia Portions of I-16 near Savannah, and I-516 Data comes through deal with I-95 Corr Coalition Mostly probe-based
Replacement of TMC X-wall Stackable DLP cubes Mitsubishi 80 screens First total replacement since 96
HERO ALADS system Automatic Location and Dispatch System HEROs and TMC Operators can exchange incident data directly through system without need for voice communications
HERO ALADS system Operators at TMC can track HEROs on map within Navigator Helps determine the nearest HERO Reduces response time

GA 400 Flex-Shoulder Lane Not specifically an ITS project, but Navigator data used to determine hours Cameras used to sweep lane each morning Navigator data used to measure effect Message signs used to reinforce hours
Future Flex-Lanes? Northbound GA 400 may be added Similar part-time operation Evening rush hour Possible ITS deployments for signage SHOULDER OPEN
Ongoing Contracts
ITS Maintenance In year 2 of 5 Replacement Phase Maintenance Phase
ITS Maintenance
ITS Operations and Support Provides Human Resources to run the TMC Operators/Dispatchers Supervisors Traffic Specialists In year 2 of 6 (July 2017)

Arterial Management and Local Integration
Regional Traffic Ops Program Active Traffic Management Significant Commuter Corridors 11 corridors Peak Hour Periods Equipment Upgrades / Maintenance Communications
RTOP Corridors
Equipment Repair Vehicle Detectors 2,150 Replaced 537 Repaired Pedestrian Detectors 1,394 Replaced 248 Repaired Percent Operational 100% 95% 90% 85% 80% 75% 70% Operational Detection Program Goal Vehicle Detection Pedestrian Detection
Program Benefits During the AM/PM peaks over the last 12 months: Reduced number of stops by 5.9% Eliminated 1.1 million hours of delay Saved 680,583 gallons of fuel Increased throughput by 4%
Arterial Cameras Cameras on RTOP corridors Integrated into Navigator Available to all statewide sys users Many more planned
Bluetoad Cobb County US 41 Bells Ferry Chastain Rd Barrett Pkwy Integrated into Navigator Arterial Detection
Corridor Management Ability to react to freeway events Knowledge of situation on arterials Example on Moreland Ave
TCC Integration John s Creek Devices Integrated into Navigator Using standalone system as primary Cobb County NTP given for Delcan to install video servers (RTOP$) Using Statewide system solution Gwinnett County Seeking standalone Navigator alternative Working on Skyline solution Needs for traveler info customizations Sandy Springs, Alpharetta and Roswell SR 9 Delcan on team, Nav 2 to be installed
Ongoing Research Efforts
Technology Scan of Future Traveler Information Systems and Applications to Georgia Dr. Kari Watkins, Civil Engineering, Ga Tech What types of info do travelers need? What improvements in sensing technologies could enable these types of info? What role can wireless technologies play?
Technology Scan of Future Traveler Information Systems and Applications Objectives: to Georgia Provide an understanding of possible future directions in traveler information systems Identify traveler information strategies that GDOT might consider as part of its ITS program
Technology Scan of Future Traveler Information Systems and Applications to Georgia Tasks: Literature Review and interviews Current state of traveler info in Atlanta Survey of Navigator users and forums Identify strategies and next steps
Information Services in Social Networked Transportation Dr. Hans Klein, Public Policy, Ga Tech Dr. Kari Watkins, Civil Engr., Ga Tech Analysis of information flows and institutions in surface transportation to promote new info services Evolving role of state DOTs as transportation becomes more information intensive
Spec Updates
Spec Updates Standard Specs only published about every 10 years, next cycle is 2013 ITS hasn t been in Standard Specs to date Instead used Special Provisions for each project Now, ITS devices WILL be in standard specs: Definitions of devices Processes for approval, testing, warranties, acceptance, payment, etc
Spec Updates GDOT will still use Special Provisions for ITS: More detailed Installation and technical requirements With Gresham, Smith and Partners, updated: 682 Electrical Wire, Cable and Conduit 926 & 927 Wireless Comm Equipment 935 Fiber Optic Systems 936: CCTV Cameras 937: Vehicle Detection Systems 939: Communication and Electronic Equipment
Spec Updates Currently being revised: 631: Permanent Changeable Message Signs 797: Hub Building 940: Navigator ATMS Integration Fewer changes to these, mostly updated references
Spec Update Highlights 682: Added directional boring, removed multimode fiber (except for temporary) 926: Added devices that support Cellular routers, Ethernet Broadband Wireless and Wi-Max 935: Dial-up modems removed. No more mechanical splices 936: Added IP addressable cams, HD cams, H.264 compression, night-vision cams 937: Clarified accuracy reqmnts, added type for pucks, focused more on Functional reqmnts
Future Plans / Endeavors
Variable Speed Limits Top End of I-285 Design/Build approach Includes raising default speed limit to 65 mph Will use existing detection Designed to harmonize the flow of traffic Increase throughput Reduce crashes
New Website Current website not meeting expectations of public (or GDOT) Meridian developing new site (and apps) now Will be similar to VDOT s 511 site Rollout in November Will bring back several features including travel times and customization
Virginia DOT site
Statewide Traffic Flow Data Currently missing data on most freeways outside metro INRIX data proving reliable Costs coming down Will enrich 511 and website Help locate incidents
Statewide Traffic Flow Data Currently missing data on most freeways outside metro INRIX data proving reliable Costs coming down Will enrich 511 and website Help locate incidents
Cameras at Every Interchange Atlanta model for ITS does not make sense for rest of state. New technologies are making wireless video easier and cheaper Start in cities (Columbus, Augusta and Savannah) Expand statewide on all limited-access roadways
Managed Lane Systems TMC to be more involved in future managed lane systems Operate gates More electronic signage Incident Management SRTA will still set rates I-75 south and Cobb Co
