Smart solar road studs that light up in response to traffic light changes were first used at the junction of British highways in 2018 to improve driver safety. The British Highway Association has installed about 170 innovative solar road stud lights on one of England’s busiest highways intersections-more than 90,000 vehicles are used every day.
When the traffic lights turn green, the smart solar road stud lights will light up, so drivers can clearly see the lane they should follow. The cables under the road are connected to the traffic lights through the nearby automatic controller. These solar studs lights can be seen up to 1,000 meters away-much larger than traditional reflective cat eyes-and have been proven to help prevent drivers from drifting between lanes, thereby reducing the risk of collisions.
“Innovative solar road stud lights and other improvements we are introducing will make it easier to navigate intersections and benefit thousands of drivers every day.”
“Introducing smart solar road studs to respond to changes in traffic lights on busy roundabouts is a continuation of the traditional road stud heritage, but it takes advantage of existing new technologies. The new solar road stud lights have been shown to reduce lane violations by more than 50% under certain conditions, so it is a good way to help improve safety for all road users.”
Now both traditional road stud and solar road stud lights are being used in large quantities. Facts have proved that these solar road stud lights provide safety protection for drivers who are driving on unlit roads at night.
