You likely have seen the push-to-cross buttons scattered across various crosswalks in NYC.
The functionality and effectiveness of these buttons is often challenged, and with good reason. The primary reason is because most of them are not even connected to the system that governs the traffic lights! As originally reported by the New York Times in 2004:
“…the city deactivated most of the pedestrian buttons long ago with the emergence of computer-controlled traffic signals. More than 2,500 of the 3,250 walk buttons that were in place at the time existed as mechanical placebos.”
