1 Navigator Update Mark Demidovich, P.E. Asst State Traffic Engineer Georgia DOT

2 Topics New System Enhancements Ongoing Contracts (Operations and Maint) Arterial Management and Local Integration Ongoing research efforts Specification updates Future plans / endeavors

3 Navigator Background

4 Navigator Background

5 Current Coverage - Atlanta Added I /- miles 550+ cameras 110+ signs 165 ramps

6 Current Coverage - Statewide I-475 in Macon City of Macon Hurricane Evac Dalton area CMS Adel area CMS 8 other scattered CMS (weigh sta)

7 New System Enhancements

8 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

9 Replacement of TMC X-wall Stackable DLP cubes Mitsubishi 80 screens First total replacement since 96

10 HERO ALADS system Automatic Location and Dispatch System HEROs and TMC Operators can exchange incident data directly through system without need for voice communications

11 HERO ALADS system Operators at TMC can track HEROs on map within Navigator Helps determine the nearest HERO Reduces response time

12 System Screenshots

13 System Screenshots

14 HERO Assists

15 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

16 Future Flex-Lanes? Northbound GA 400 may be added Similar part-time operation Evening rush hour Possible ITS deployments for signage SHOULDER OPEN

17 Ongoing Contracts

18 ITS Maintenance In year 2 of 5 Replacement Phase Maintenance Phase

19 ITS Maintenance

20 ITS Operations and Support Provides Human Resources to run the TMC Operators/Dispatchers Supervisors Traffic Specialists In year 2 of 6 (July 2017)

21 ITS Operations and Support

22 Arterial Management and Local Integration

23 Regional Traffic Ops Program Active Traffic Management Significant Commuter Corridors 11 corridors Peak Hour Periods Equipment Upgrades / Maintenance Communications

24 RTOP Corridors

25 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

26 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%

27 Arterial Cameras Cameras on RTOP corridors Integrated into Navigator Available to all statewide sys users Many more planned

28 Bluetoad Cobb County US 41 Bells Ferry Chastain Rd Barrett Pkwy Integrated into Navigator Arterial Detection

29 Corridor Management Ability to react to freeway events Knowledge of situation on arterials Example on Moreland Ave

30 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

31 Ongoing Research Efforts

32 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?

33 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

34 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

35 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

36 Spec Updates

37 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

38 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

39 Spec Updates Currently being revised: 631: Permanent Changeable Message Signs 797: Hub Building 940: Navigator ATMS Integration Fewer changes to these, mostly updated references

40 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

41 Future Plans / Endeavors

42 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

43 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

44 Virginia DOT site

45 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

46 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

47 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

48 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
