FDOT District 4 Traffic Signal Timing
Increases travel speeds and reduces fuel consumption and vehicle emissions.
Quick Facts
Conducted traffic signal retiming studies and developed optimized traffic signal progression timing plans for selected corridors in Martin County and Palm Beach County, Florida
Includes 56 intersections spread across four corridors in Martin County and 73 intersections in Palm Beach County along five corridors
Results
Increases travel speeds and reduces fuel consumption and vehicle emissions
Reduces vehicle delays and fuel consumption; when converted into monetary savings, the project’s benefit results in approximately $17.5 million over three years, representing a 50 to 1 benefit-to-cost ratio
Our Work
Field-verified existing lane configurations, intersection geometry and current traffic signal phasing for all intersections in the network
Collected link speeds by performing floating car travel time and delay surveys using Tru-Traffic software
Recorded actual speeds of vehicular traffic between intersections to improve the accuracy of the modeling process
Geo-referenced all signal locations in Synchro models using the appropriate geographic coordination system
