Traffic Signal System Upgrades & Retiming Project - 65 Intersections

The Traffic Signal System Upgrades & Retiming Project addresses an overall approach to traffic signal improvements within Downtown Atlanta, including equipment modernization and signal operation needs. A 16-intersection ‘demonstration project’ concludes in July 2010. Downtown-wide improvements will replicate the work of the demonstration project within key Downtown corridors, improving up to 65 additional intersections.

Project Goals:

• Improve traffic signal system operations and mitigate traffic congestion
• Modernize traffic signal equipment and address deficiencies
• Ensure consistent communication among intersections
• Provide for a fully -functioning network
• Improve capacities for maintaining Downtown signal operations

Project Components:

• Replacement of traffic signal controller units and cabinets
• Replacement of outdated incandescent signal heads with new Light Emitting Diode (LED) heads and pedestrian count-down signal heads
• Wireless communication upgrades and system integration
• Development of new timing and optimization plans for better traffic movement
• Assessment of the benefits of the improvements with measurement of vehicle emissions, travel time savings and fuel consumption
