Traffic Operations
Regional Traffic Operations Program
The Regional Traffic Operations Program (RTOP) is a multi-jurisdictional, cutting-edge signal timing program with the goal of improving traffic flow and reducing vehicle emissions through improved signal timing. The difference between this effort and the normal signal timing operations is Georgia DOT has provided additional signal timing experts focused solely on Atlanta's busiest arterial roadways. These signal timing experts are assigned corridors that cross city and county boundaries, and they are now working with local jurisdictions to make signal timing seamless as motorists traverse through multiple jurisdictions.

RTOP also assists local jurisdictions with maintenance resources that make it possible to quickly find and repair problems that can negatively impact signal operations, such as damaged vehicle and pedestrian detectors. Furthermore RTOP is aggressively upgrading the traffic signal communications to the signals, no matter which jurisdiction operates them. Once completed RTOP will be able to remotely monitor all corridors from Georgia DOT's Transportation Management Center. This will enable quicker response times to repair signal problems, and soon we'll have the ability to remotely implement multi-jurisdictional timing plans in response to an incident or special event.
