The Secret of the Spinning Cone
Not really a secret, but on most automated pedestrian crossings a spinning cone can now be found underneath the push button panel. It’s there for those people who can’t see the lights, like visually impaired or blind people, so when the green man lights up to show traffic should stop and it’s the pedestrian’s turn to cross, the ridged cone starts rotating and, as they feel it spinning, they know they have the right of way. This, of course, would be used in conjunction with listening for traffic.
