Traffic Signal Left Turn Phasing Upgrades, T-128

Flashing Yellow Arrow Traffic Signals

ENGINEERING MANAGER: Ted Semaan, P.E.
PROJECT ENGINEER: Daniel Gruezo


PROJECT DESCRIPTION:

In the Spring of 2014, drivers in the City of Torrance will encounter a new type of traffic signal display featuring the Flashing Yellow Arrow Protected/Permissive Left Turn.

 

Currently in Torrance, there are two types of traffic signal operations relative to left turns:

  • Protected: the driver turning left has a green arrow, and opposing oncoming traffic must stop; and,
  • Permissive: the driver turning left has a solid round green light, but must yield to oncoming traffic.
  • With the Flashing Yellow Arrow Protected/Permissve Left Turn signal display, drivers will have the right-of-way to turn left on a green arrow (the Protected mode), and will be allowed to turn left on a flashing yellow arrow after yielding to on-coming traffic (the Permissive mode).

    The new signal is designed to move traffic more efficiently, safely, and reduce delays.


     

    PROJECT LOCATION:


    Initially, the Flashing Yellow Arrow signals will be installed at the locations below:

  • Arlington Ave./Sepulveda Blvd. (in the North/South Directions along Arlington)
  • Cabrillo Ave./Sepulveda Blvd. (in the North/South Directions along Cabrillo)
  • 182nd St./Prairie Ave. (all directions)


  • Community Outreach Meeting Schedule

    A presentation on the traffic signal operations of the Flashing Yellow Arrow display will be given on the below listed dates. Meetings were scheduled for audiences based on location, but all drivers are welcome to attend any meeting at their convenience. Your consideration and attendance to any of the outreach meetings to learn more about this type of traffic signal is greatly appreciated!
