FDOT District 1 Bee Ridge Smart Signal Project in Sarasota County

Project Description: This project is intended to apply technology improvements to address safety issues along Bee Ridge Rd (SR 758) corridor between US 41 and I–75 in Sarasota County. The project will add advance detection for dilemma zone protection on all major street approaches; replace stop bar detection on all approaches; install closed–circuit television (CCTV) cameras at intersections that do not presently have this coverage; and install connected vehicle infrastructure (roadside units) to transmit MAP and SPaT messages and to receive Basic Safety Messages from vehicles equipped with on–board units. .
