Highway England has installed 175 airport runway LED road studs to help delineate lanes at one of the busiest highway intersections in England, where more than 90,000 vehicles pass by each day. In addition, this smart LED road stud will turn on when the traffic light turns green to help drivers stay in the correct lane. This is the first time that intelligent traffic lights have been introduced at major highway intersections.
The innovative LED studs are visible from 900 meters away, farther than the traditional reflective studs, and have been proven to help prevent drivers from drifting between lanes, reducing the risk of collisions. The cable under the road connects the peg to the traffic light through a nearby controller unit. When the traffic signal light turns green, the LED peg will automatically turn on.
As part of the Switch Island plan, the new traffic lights will be installed higher than 5 meters (higher than heavy-duty vehicles and double-decker buses) so that drivers near the intersection can clearly see when the smart LED studs change . In addition, road layouts, lane markings, and lane obstructions have also been changed. Four new overhead platforms will also be set up in each lane so that drivers know which lane they should stay in.
The smart road stud designer Andy Salotti said: "This is the first time that a dynamic division project has been carried out at the main highway junctions of the strategic road network in England. LED road studs synchronized with green traffic lights will provide clear lane guidance for drivers. .This solution will reduce the probability of drivers deviating from the lane, thereby reducing the number of accidents at critical intersections, congestion, and driver frustration due to road traffic collisions.
