Good Practice Traffic Signal Timing - Upgrading Systems (TX, CA, and FL)

Several municipalities have worked to synchronize, optimize, or otherwise upgrade their traffic signal systems in recent years. Below are a few examples of the benefits some have realized:

• The Traffic Light Synchronization program in Texas shows a benefit-cost ratio of 62:1, with reductions of 24.6 percent in delay, 9.1 percent in fuel consumption, and 14.2 percent in stops.
• The Fuel Efficient Traffic Signal Management program in California showed a benefit-cost ratio of 17:1, with reductions of 14 percent in delay, 8 percent in fuel consumption, 13 percent in stops, and 8 percent in travel time.
• Improvements to an 11-intersection arterial in St. Augustine, Florida, showed reductions of 36 percent in arterial delay, 49 percent in arterial stops, and 10 percent in travel time, resulting in an annual fuel savings of 26,000 gallons and a cost savings of $1.1 million.
