The intended operation of the toucan crossing by the University Arms is fundamentally broken. The crossing sequence starts with cyclists from Parkers Piece being given a green filter to go both left and right onto Regent Street, followed by the left filter going red and pedestrians being given the green light to cross. Except of course literally 100% of pedestrians see the high level green filters, ignore their street level red and start crossing just as bikes turn left into them. How did anyone ever think this would work?
