Office of Transportation Infrastructure Management

Atlanta Department of Transportation’s Office of Transportation Infrastructure Management (TIM) is responsible for maintaining and operating the City of Atlanta’s multi-modal transportation system for residents, commuters, and visitors. 

Traffic Signals and Streetlights

Traffic Signals

The City of Atlanta Street Light Shop and Transportation Communication Center (TCC), both a part of the Atlanta Department of Transportation (ATLDOT), manage all issues related to flashing signals—malfunction caused by inclement weather, downed power lines, etc.

Streetlights are proven to help prevent both crime and traffic crashes. In April 2021, Mayor Keisha Lance Bottoms announced the “One Atlanta—Light Up the Night” initiative to increase the City’s streetlight footprint by 10,000 lights—with focus on areas with high rates of traffic crashes and crime.

Signs and Markings


TIM maintains roughly 100,000 traffic and street name signs and installs new signs to accommodate changes in traffic operations as needed. 


TIM maintains lane lines, pavement symbols, crosswalks, stop bars, and intersection markings on roughly 1,400 centerline miles of city streets, and installs new crosswalks as needed at ADA ramp locations.

Right-of-Way Permitting

Any disturbance to the public right-of-way requires a permit issued by the Department of Transportation. Right-of-Way Permits are required for lane and road closures as well as other activities in the public right of way. Applicants may be referred for this type of permit through the Department of Transportation.

The Department of Transportation issues various permits for working in or blocking the public right-of-way. Examples of such work may include installing or making repairs to a driveway apron or sidewalk; building a structure that requires a driveway apron; or tapping into an existing sewer/sanitation line.

For more information, please visit Right-of-Way Permits

Traffic Studies

Traffic Studies include site assessments, crash histories, and 24-hour volume or peak-hour turning movement counts. This process can be lengthy due to work required and volume of requests.
