KELLER (CBSDFW.COM) – Traffic signals with yellow, flashing left-turn arrows that have popped up throughout North Texas in recent years are debuting in Keller.
The traffic lights are at the intersection of Bear Creek Parkway and Rufe Snow Drive in front of Moviehouse & Eatery.
The decision to proceed with the flashing yellow arrow design was made with the expectation that Keller drivers will continue to see more of the lights in the future as they become the new standard nationwide.
City staff said it anticipates that when the signals along FM 1709/Keller Parkway are retimed by TxDOT next year, many of them will be transitioned to the new style, just as the state did earlier this year in conjunction with retiming the signals along Southlake’s portion of the corridor.
“Once we have the opportunity to observe how Keller drivers interact with the new signal style and how it impacts our traffic movements, I expect we’ll look at additional conversions in the future,” said Public Works Director, Matt Kite. “Similar to having signals switch to flash mode along Rufe Snow and North Tarrant Parkway late at night, this is just another tool to assist in keeping traffic moving.”
Studies by the Federal Highway Administration show that flashing yellow left-turn arrow signals help prevent crashes and move more traffic through intersections.
While flashing yellow arrows mean the same thing as traditional green circles, indicating that a driver turning left needs to yield, transportation experts said the new system keeps drivers safer, encouraging them to proceed with caution while turning left at a time when they would traditionally see the solid green light they associate with “Go.”
The style also helps eliminate accidents caused by left-turning drivers who cut across an intersection as the lights on their side transition toward red because they believe oncoming traffic, too, is coming to a halt.
The addition of the yellow flashing arrow also offers traffic engineers more options to handle variable traffic conditions, and provides more opportunities for drivers to turn left during peak traffic times and at busy intersections.
