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

ITS Operations and Support

• Provides Human Resources to run the TMC

• Operators/Dispatchers • Supervisors • Traffic Specialists • In year 2 of 6 (July

2017)

Program Goal

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

Arterial Detection

• Bluetoad • Cobb County • US 41 • Bells Ferry • Chastain Rd • Barrett Pkwy • Integrated into

Navigator

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

to Georgia

Objectives: • 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

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
