In the United Kingdom, what type of crossing uses a flashing green signal for pedestrians?

In the United Kingdom, a pelican crossing uses a flashing green signal for pedestrians.

“Pelican” comes from “pedestrian light-controlled” crossing. When a pedestrian presses the button, traffic receives a red signal and the pedestrian receives a green signal to cross. The pedestrian signal then flashes green before changing to red.

The flashing stage historically warned pedestrians who had not started crossing to wait, while people already on the crossing could finish. Modern installations have increasingly been replaced by puffin crossings, which use sensors and different signal arrangements.

Pelican crossings are often confused with puffin and toucan crossings. Puffin crossings detect pedestrians and place signals on the near side; toucan crossings allow cyclists to cross alongside pedestrians. Zebra crossings, by contrast, use road markings and Belisha beacons rather than traffic signals.
