In recent years, drivers have begun to see the flashing yellow arrow (FYA) in left-turn lanes in Florida. Studies have shown the safety advantages of the FYA, which has been shown to be easier for drivers to interpret than traditional yield-on-green signals. The Florida Department of Transportation has sponsored several projects to develop tools to assist traffic engineers in managing FYAs. In the first phase of this project, University of Central Florida (UCF) researchers developed a decision support system (DSS) to evaluate when to activate a flashing yellow arrow (FYA) in relationship to traffic volumes. The DSS was able to flag intersections requiring traffic engineers’ attention and to assist traffic engineers in selecting FYA left-turn modes for specific times of day
