Puffin Crossing
A puffin crossing (its name derived from the phrase "pedestrian user-friendly intelligent") is a type of pedestrian crossing in use in the United Kingdom. The design is distinct from the older pelican crossing in that the lights signalling to the pedestrians are on the same side of the road as the pedestrian, rather than across the road. From 2016, pelican crossings began to be phased out in the United Kingdom, to be replaced with puffin crossings. They have two sensors on top of the traffic lights (PCD – pedestrian crossing detector, and PKD – pedestrian kerb detector). These sensors detect if pedestrians are crossing slowly and can hold the red traffic light longer if needed. If a pedestrian presses the button but then walks off, the PKD will cancel the request making the lights more efficient. Function Unlike the older pelican crossing designs, where the pedestrian signal lights are mounted on the opposite side of the road, the puffin crossing has them mounted at the n ...

Puffin Crossing Nearside Signals
Puffins are any of three species of small alcids (auks) in the bird genus ''Fratercula''. These are pelagic zone, pelagic seabirds that feed primarily by diving in the water. They breed in large Bird colony, colonies on coastal cliffs or offshore islands, nesting in crevices among rocks or in burrows in the soil. Two species, the tufted puffin and horned puffin, are found in the North Pacific Ocean, while the Atlantic puffin is found in the Atlantic Ocean, North Atlantic Ocean. All puffin species have predominantly black or black and white plumage, a stocky build, and large beaks that get brightly colored during the breeding season. They shed the colorful outer parts of their bills after the breeding season, leaving a smaller and duller beak. Their short wings are adapted for swimming with a flying technique underwater. In the air, they beat their wings rapidly (up to 400 times per minute) in swift flight, often flying low over the ocean's surface. Etymology The English name ...
