2018 Flashing Yellow Arrow Signals

 

OVERVIEW

Flashing Yellow Arrow (FYA) turn signals are widely used to improve signal operations and traffic safety. In 2017, the City conducted a FYA feasibility study for all of the city's signalized intersections. The analysis identified those intersections that met certain physical configuration and safety criteria making it feasible to install FYA left turn signals.

The City installed FYA at five intersections in 2017 and decided to install FYA at up to eight intersections in 2018. Project is currently completed. The table below shows locations where FYA have been installed with this project:
