Introducing New, Safer Traffic Signals

Get ready to yield to the yellow at intersections around town.

RC Safer Traffic Signals

Motorists traveling along Milliken Avenue this past summer were among the first in the City to see the new flashing yellow arrow (FYA) on left-turn traffic signals where drivers must yield to oncoming traffic. The newly installed traffic control devices are located at:

While the new flashing yellow arrows will look a bit different to pedestrians, cyclists, and motorists, research suggests they are more intuitive and safer than traditional signals. Studies by the Federal Highway Administration show the FYA display increases safety because it is more effective at catching a driver's attention when yielding to oncoming traffic.

The other purpose of the FYA is to use improved technology to make the City's overall network of traffic signals more efficient. The design will catch driver's attention and reduce wait time. Those time savings allow for more opportunities to make a left-turn than traditional three-arrow (red, yellow and green) indications.
