Oct.-2018,according to foreign media reports, Highways England installed 175 airport runway LED cat eyes to help drive one of the busiest highway intersections in England, which with 90,000 daily intersections cars pass by. In addition, this smart LED cat eyes will turn on when the traffic light turns green, helping the driver stay in the correct lane. This is the first time that traffic smart lights have been introduced at major highway intersections.
The innovative LED cat eyes on road are visible 900 meters away, farther away than traditional
reflective cat eyes, and have been proven to help prevent drivers from drifting between lanes,
reducing the risk of collision. The cable under the road surface connects the smart cat eyes to
the traffic light through a nearby controller unit. When the traffic light turns green, the LED cat
eyes opens automatically.
As part of the Switch Island program, new traffic lights will be installed above 5 meters (above load-
bearing vehicles and double-decker buses) so that drivers close to the intersection can clearly see
when smart LED cat eyes change . In addition, road layouts, lane markings, and lane obstacles have
also been changed, and four new overhead platforms will be placed in each lane so that the driver
knows which lane they should remain in.
The smart cat eyes designer Andy Salotti said: "This is the first time that a dynamic division project is carried out at the main highway junction of the strategic road network in England. The LED cat eyes synchronized with the green traffic lights will provide clear lane guidance for the driver. The solution will reduce the driver's probability of deviating from the lane, thereby reducing the number of accidents at key intersections, congestion, and driver frustration due to road traffic collisions."
