The Rhode Island Department of Transportation (RIDOT), in the US, has installed new traffic technology, which features a flashing yellow arrow signal at the intersection of Langworthy Road and Route 1 (Post Road) in Westerly, Rhode Island.
RIDOT added the yellow arrow signal to the existing sequence of traffic lights at the intersection to increase the safety of drivers making left turns from Langworthy Road northbound onto Route 1 South and to help traffic move more easily.
The department replaced the old traffic light under the $2.5m resurfacing project for Dunn's Corner Road and the Langworthy intersection.
The oncoming traffic will have a green light to move and will see a flashing yellow arrow signal indicating to drivers to be prepared to stop before the change of signal.
Drivers can still proceed at the intersection during the flashing yellow arrow signal, if the intersection is clear.
The oncoming traffic has a green light during a flashing yellow arrow and the sequence ends by showing a steady yellow arrow, which is followed by a steady red arrow.
National studies showed that intersections equipped with flashing yellow arrow signals, in comparison to the traditional signals, have fewer crashes and also reduced traffic times and minimised delays.
Transportation departments across the US are implementing flashing yellow arrow signals at intersections.
