…but we can minimize the number of red lights, stops and delays.
County’s Role: County operates and maintains all County, FDOT, and municipal traffic signals. Network is countywide and crosses all municipal boundaries. Eliminates jurisdictional barriers and allows seamless synchronization.
Benefits: Minimize Fuel Consumption Reduce Greenhouse Gas Emissions Reduce Travel Delays Enhance Economic Development Improve Safety 6
Two Key Steps to Improve Traffic Synchronization Improve Signal Timing Plans “Green Lights.” Upgrade Hardware and Software. 7

Each Roadway Corridor has Three Different Synchronized Timing Plans Morning: 6:00 – 9:00 AM Afternoon:3:00 – 8:00 PM Off-Peak:9:00 AM – 3:00 PM 8:00 PM – 12:00 Midnight (Non-Synchronized Midnight to 6:00 AM) 9
“Green Lights” Performance Results Travel Time Saved: 10% to 43% Stops Reduced: 10% to 32% Positive Feedback from Motorists 23
“Green Lights” Performance Results (Cont.) Fuel Saved: $31 Million/Year Carbon Emissions Reduced: 660,000 Metric Tons/Year = 7% Reduction of Transportation Emissions = 3% Reduction of Total Emissions 24
Synchronized Traffic Signals Cannot Solve These Conditions: Overcapacity/Rush Hour Crashes School Zones Railroad Crossings and Bridge Openings Construction Emergency Vehicle Preemptions Traveling Over Speed Limit 25
