They're toucans I think. You can see the green cycle light on the side road crossing in https://www.mapillary.com/app/?z=18.670097595608446&lat=51.890287400000005&lng=-1.1646897999999055&dateFrom=2022-01-01&pKey=1183152156625413&focus=photo&x=0.49370243453782436&y=0.590217600850204&zoom=0.45478723404255317 . The other crossings all have two lower lights - presumably a green man and a green cycle, though you can't see them lit in any of the images. I've added crossing_ref=toucan to all the crossing points here.
