A traffic study is performed to determine the need for a traffic control device.

Examples of traffic control devices include, but are not limited to:

• New stop signs
• A reduction of the speed limit
• Establishment of new speed limits if none currently exists on the entire street
• New traffic signals, including a new turn signal and speed monitors

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

If requesting a traffic study:

• Contact ATL311 at 404-546-0311 or 
• Submit an online service request below

Provide the location of the proposed traffic study, a brief reason for the request and specify the type of traffic control device needed.  

NOTE: A mailing address should be included when submitting a request for a traffic study. If approved, once signed by the Atlanta Department of Transportation (ATLDOT), a petition package will be mailed to the customer. The customer must obtain signatures of 75% of their neighbors and return the petition to ATLDOT before any additional action will be taken regarding installation. The petition package will include full instructions.
