In the Fall of 2021, FDOT District One Traffic Operations was challenged by L.K. Nandam, the District One Secretary, to devise a strategy to reduce speeds and improve safety along corridors, using signal timings. The initial corridor chosen was US 41 in Manatee County, from Tallevast Rd to Cortez Rd. This corridor had the highest number of fatal accidents per mile in District One, and was one of the highest in the State of Florida. A strategy was developed to increase saturation, by lowering cycle lengths, along with adjusting offsets to deter speeding through the corridor.
With nearly three years of data, the project has shown to have significantly reduced the number of fatal and serious injury accidents. This strategy has been expanded to other corridors and looks to be a promising tool for improving safety and moving the needle towards FDOT’s Vison Zero.
