Who'd have thought it?
Zoomup:
Pelicans and puffins. What's the difference?
Quite a lot!
For cars, pelicans have a flashing amber phase, puffins do not.
For pedestrians, pelicans have the green and red men on the other side, puffins have them on the same side, so once you have started, you don't know when to start running. Pelicans have a fixed period (depending upon the width of the road), puffins have sensors so in theory you get as long as you need to cross. Pelicans abort the request to stop if a pedestrian is no longer waiting. All clever stuff.
I know that crossing - must have a look some time. ?
