Department of Transportation
Innovative technology is at the center of the Georgia Department of Transportation’s (GDOT) strategy to keep traffic moving smoothly throughout the state – and especially in densely populated metropolitan areas – regardless of whatever situation arises.
GDOT has deployed an array of impressive technologies that enable its teams to:
- Quickly identify and respond to routine, daily problems and life-threatening emergencies.
- Easily share real-time information with other responders at the state, local, and federal levels, and news media.
- Prepare for and respond to weather emergencies, such as snow, ice storms, and hurricanes.
- Pro-actively collect and analyze data to support decisions for improving daily operations and strategic planning for future enhancements.
GDOT’s WebEOC (Emergency Operations Center) application provides real-time information to support daily operations and emergency management, and it’s become GDOT’s cornerstone during inclement weather. The application makes it quick and easy to share documents, as well as upload photographs and view maps and other GIS information. The result is comprehensive, up-to-the-minute situational awareness.
GDOT couples WebEOC with the SouthernLINC Wireless iDEN (Integrated Digital Enhanced Network) radio system to add statewide voice communications capabilities between multiple state agencies and to connect state agencies with federal and local agencies when necessary. In addition, the establishment of talk groups enables all appropriate personnel to easily connect and seamlessly take part in discussions about specific situations. The result is a coordinated response across teams and agencies.
Transportation telematics is a third component of GDOT’s technological response to transportation management. A suite of tools helps identify and assess road hazards and determine appropriate responses. The Road Weather Information System monitors road temperatures to detect the presence of rain, snow, ice, and wind. In addition, all GDOT emergency-response vehicles are equipped with GPS tracking software, which allows managers to dispatch the closest and most appropriate vehicle to the scene of an incident.
Tools for making traffic information readily available to the general public are yet another component of GDOT’s technology solutions. Dialing 511 on a mobile phone allows callers to report traffic problems, and they can access real-time information to help plan their driving routes. GDOT’s 511 Navigator website at www.511ga.org features a GIS map of the state with icons for traffic cameras and message signs over interstate highways and major roads. Users can click on camera icons to see live video feeds from specific locations and on message sign icons to read the message currently displayed on the sign. Users can create personal accounts and designate favorite cameras for quick access.
Taken together, GDOT’s technology tools and solutions ensure a level of situational awareness that was previously unattainable, and they connect with and complement other state information systems, thereby strengthening communications, information sharing, and response coordination across all involved state, local, and federal agencies.
