Slide 1: NaviGAtor

Georgia's Intelligent Transportation System

Talking Technology and Transportation (T3) Webinar
March 4, 2008

Slide 2: The Beginning of NaviGAtor

Primarily in response to Atlanta's selection as host of the 1996 Summer Olympic games

  • What can we do to keep traffic moving during this massive influx of people?
  • What technologies can we show off to the world related to transportation?

Slide 3: The Beginning of NaviGAtor

  • Georgia DOT took lead role in developing system
  • Primarily used Demonstration Project (DPI) and Congetions Mitigation (CMAQ) funds
  • GDOT partnered with FHWA, five local counties, the City of Atlanta, and transit (MARTA)

Slide 4: Initial Concept

NaviGAtor was to be:

  • Primarily a freeway incident and traffic management program
  • Secondarily a traveler information system
  • Centered in a GDOT Transportation Management Center (TMC)
  • Networked with satellite Transportation Control Centers (TCCs

Slide 5: Initital Concept

[Image: A diagram of nine boxes surrounding a center box, representing the initial concept of NaviGAtor. The center box is the GDOT traffic management center surrounding by nine satellite transportation control centers: Athens, Savannah, Atlanta, MARTA, Gwinnett Co., Fulton Co., Dekalb Co., Clayton Co., and Cobb Co.]

Slide 6: Initital Concept

[Image: The same diagram found on the previous slide showing nine boxes surrounding a center box, representing NaviGAtor. Each of the satellite transportation control centers, with the exception of MATRA, collects and exchange data about signals and local streets; MARTA contributes transit data. The nine satellite transportation control centers are Athens, Savannah, Atlanta, MARTA, Gwinnett Co., Fulton Co., Dekalb Co., Clayton Co., and Cobb Co.]

Slide 7: Initital Concept

  • Instead of being housed in same facility, partner jurisdictions are tied together virtually
  • All partners run the same NaviGAtor software
  • Interconnected via fiber
  • All video is shared, including control
  • Each partner maintains own database, but info is shared
  • MOUs signed between State and locals

Slide 8: Roles

Georgia DOTLocal Jurisdictions
  • Freeway surveillance
  • Freeway speed/volume detection
  • Freeway incident management
  • Ramp metering
  • Traveler Info (message signs)
  • Traveler Info (website and 511)
  • HOV Lane monitoring
  • State Route management
  • Construction tracking statewide
  • Maintenance dispatch
  • Traffic signal repair dispatch
  • Arterial surveillance
  • Traffic signal operation
  • Arterial Traveler Info (message signs)
  • Arterial Traveler Info (Traffic TV)

Slide 9: Common Software Platform

Slide 10: Incident Management

[Image: Computer screen shot of the Navigator software application. The screen shows incident management data divided into columns. The jurisdiction column—the location of the incident—is highlighted. ]

Slide 11: Incident Management

[Image: Computer screen shot of the Navigator software application. The screen shows incident management data divided into columns. The "Filter by" button is highlighted, showing that the tool has filtering capability. ]

Slide 12: Incident Management

[Image: Computer screen shot of the Navigator software application. The screen shows incident management data divided into columns. A pop-up box that displays the result of a "Filter by" action. ]

Slide 13: Camera Selection

[Image: Computer screen shot of the Navigator software application. The screen shows a filtered list of cameras by jurisdiction. ]

Slide 14: Camera Selection

[Image: Computer screen shot of the Navigator software application. The screen shows a filtered list of cameras by jurisdiction. ]

Slide 15: Camera Selection

Slide 16: GDOT NaviGAtor Overview

Slide 17: GDOT NaviGAtor Overview

  • Devices primarily concentrated in Metro Atlanta
  • Some statewide elements:
    • Hurricane evacuation system along coast
    • Weather stations statewide
    • Message signs scattered around the state
  • Responsibility for state routes across Georgia
    • Clearinghouse for all incidents/construction

Slide 22: Incident Management

  • Incident info shared with police via phone
    • Also on-scene coordination relayed thru dispatch
  • Traffic Incident Management Enhancement (TIME) task force formed
    • Made up of GDOT, police, fire, EMS, State Patrol, etc.
    • Meets frequently to discuss incident management
    • "After-action" debriefings held
  • Traffic Recovery Incentive Program
  • (TRIP) recently kicked off

Slide 23: Media Relationships

  • Share four simultaneous video feeds with all major networks in Atlanta
  • Media liaison employed at TMC
  • Incident info shared both ways with media

[Image: traffic management center. ]

Slide 24: Data Sharing with ISPs

  • All NaviGAtor content freely available
  • http://data.georgia-NaviGAtor.com
    • Includes all images
    • Raw station data (speeds, counts, etc)
    • Maps
  • Accessed by various media outlets and traffic info consolidators

Slide 25: Looking Ahead

[Images: Freeway with overpasses. Image of transportation management center. Image of freeway traffic passing under a variable messages sign. ]

Slide 26: Future Plans

  • Engage more partners
    • Counties, including those outside metro Atlanta
    • Police/fire/rescue
    • Towing/recovery
    • Media
  • Develop browser-based software
  • Incorporate traffic signals into NaviGAtor

Slide 27: Future Plans

    • GDOT revising specs to keep options open
  • Bring more value/usefulness to locals
  • Enrich 511 information
    • Cover more roadways
    • Include better utility and const lane closures
