Pardon The Progress: Express Lanes Signage Under Maintenance for GDOT Advanced Traffic Management System Upgrade

The Georgia Department of Transportation (GDOT) is upgrading its Advanced Traffic Management System (ATMS) to improve how transportation systems across the state are monitored and managed. The upgraded system will support better coordination across GDOT’s network and help operators respond more efficiently to incidents, congestion, and changing roadway conditions.

What Peach Pass Customers May Notice During the Upgrade

As GDOT transitions to the upgraded system, some messaging on Georgia Express Lane comparative travel time signs may be temporarily affected. These signs normally help Peach Pass customers compare travel times between the Express Lanes and General-Purpose lanes. During the transition, some signs may reflect the following:

  • Local lane travel time only
  • Express Lane open or closed status only
  • Temporary unavailability of Express Lane speed comparisons
Please note: These temporary changes are related to the system transition and do not affect lane operations.

What Operations Will Continue During the Upgrade

  • Express Lanes will continue to open, close, and operate normally throughout the upgrade.
  • Safety and incident messaging, including crash alerts, lane closures, weather warnings, and other roadway advisories, will also continue to display as normal to help keep drivers informed.

Why Upgrading the Advanced Traffic Management System (ATMS) Is Important

An ATMS is the technology transportation agencies use to monitor traffic in real time and manage roadway operations through tools such as cameras, digital message signs, and other connected systems. By bringing these systems together into one platform, GDOT can improve visibility across the network, support faster decision-making, and strengthen day-to-day transportation operations.

In addition, GDOT has secured a statewide iNET license, giving cities and counties across Georgia access to the same system through GDOT’s investment. This means local agencies can access modules to help manage their own transportation networks while improving coordination with GDOT and regional partners.

When Will the Upgrades Be Completed

GDOT is working to restore full comparative travel time functionality as quickly as possible. Once complete, the upgraded ATMS will support a more modern, connected approach to managing transportation operations across Georgia.

FREQUENTLY ASKED QUESTIONS (FAQS)

Comparative travel time signs show drivers the difference between:

  • Express Lane travel time (or speed)
  • General-purpose (local) lane travel time

These signs help drivers decide whether to enter the Express Lane.

An overhead electronic sign shows the I-75 and I-675 Express lanes moving at 65 mph and Local lanes at 59 mph.
An electronic traffic sign displays a 10-minute travel time for Express lanes compared to 14 minutes for Local lanes.
An electronic highway sign shows Express Lanes moving at 65 mph while Local Lanes are at 20 mph.

As part of a system upgrade, some comparative Express vs. Local travel time messaging may be temporarily unavailable.
During this period:

  • Some signs may display local lane travel time only
  • Some signs may display OPEN or CLOSED status only for the Express Lane
  • Express Lane speed comparisons may not appear

Yes.
The Express Lanes will continue to open, close, and operate normally. Only the comparative travel time messaging may be affected.

The previous system used specialized logic to calculate travel times for reversible Express Lanes. During the system transition, that specific feature is not yet available in the upgraded system. Until it is restored, some comparative messaging will be temporarily unavailable.

Depending on location, drivers may see:

Full-Color Signs:

  • Local travel only
  • No Express travel time comparison

Hybrid Signs:

  • Express Lane OPEN or CLOSED
  • Local lane speed displayed
An overhead electronic sign displays "EXPRESS LANE CLOSED" at the interchange for I-75 North and I-675.

Yes. Crash alerts, lane closures, weather warnings, and other safety messages will continue to display normally.

An electronic traffic sign displays a 10-minute travel time for Express lanes compared to 14 minutes for Local lanes.
A white pickup truck drives along a highway with light traffic and oncoming vehicles visible across the median.

GDOT is working to restore full comparative travel time functionality as quickly as possible. Updates will be provided as progress is made.
