## The Beginning of NaviGAtor

**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?

## The Beginning of NaviGAtor

**The Beginning of NaviGAtor**

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

## Initial Concept

**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)

**Initial 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**
