The agency is installing new traffic signals that feature a flashing yellow arrow phase as it makes improvements to 40 intersections under its responsibility across Western New York.
Those flashing yellow arrows allow motorists more time to make turns, improving intersection efficiency while generating time and fuel saving for motorists, while also improve safety for pedestrians crossing at those intersections.
NYSDOT also emphasized that pedestrians crossing the road always have the right-of-way over turning vehicles.
“Flashing yellow arrows on traffic signals enhance safety and help clear congestion at intersections, reducing the risk of collisions on our roads,” explained NYSDOT Commissioner Marie Therese Dominguez in a statement.
“As part of our commitment to maintaining safe, navigable roadways, we will continue to closely monitor the traffic patterns in Western New York and across the state, and we will utilize the latest and most effective technologies to guide motorists,” she added.
The agency said it deploys traffic signals with a flashing yellow arrow phase at intersections where there is an exclusive right- or left-turn lane with a protected green arrow, stopping oncoming traffic to allow motorists to turn.
The signal changes from a green arrow to a solid yellow arrow, indicating that a red signal is coming and turning motorists should not enter the intersection. That red arrow allows traffic from the oncoming direction to begin proceeding through the intersection.
After opposing traffic gets the green phase, the turn arrow begins flashing yellow, indicating that turning vehicles must yield to oncoming traffic but may proceed when there is a safe gap in traffic. The signal then turns returns to a solid yellow arrow and then to a red arrow, allowing traffic on the other road to proceed through the intersection.
Several state departments of transportation are involved in traffic signal research as a way to make roadways safer.
For example, researchers at Purdue University in collaboration with the Indiana Department of Transportation unveiled in February a new wireless communication device that could help save lives at high-speed traffic signals.
In a broader effort, the American Association of State Highway and Transportation Officials is one of several organizations that’s been calling on the Federal Highway Administration over the last two years to finalize a new edition of the Manual on Uniform Traffic Control Devices or MUTCD to help improve roadway safety.
