US 90 Signal Phase and Timing Tallahassee

Under FDOT’s TSM&O Program, arterial traffic management solutions are receiving renewed focus, especially given the technology advances offered by connected vehicles (CV). Case in point is a major Signal Phase and Timing (SPaT) project using CV technology underway at the City of Tallahassee.

The testing and implementation of SPaT at select intersections around Florida will support the advancement of Vehicle-to-Infrastructure capabilities, especially related to intersection safety applications. It will also give FDOT and local agency staff the opportunity to gain experience in the operation and maintenance of CV infrastructure and applications.

Fast Facts:
  • AASHTO challenged all states with dedicated short range communications (DSRC) deployment at 20 signals by 2020
  • US 90 Mahan Drive to have 22 signalized intersections equipped with DSRC
  • FDOT and City of Tallahassee partnership with the city to install Roadside units to broadcast SPaT information 24x7 for vehicle onboard units to receive
