Reports suggest that many walk buttons in some areas, such as New York City and the United Kingdom, may actually be either placebo buttons or nonworking call buttons that used to function correctly. In the former case, these buttons are designed to give pedestrians an illusion of control while the crossing signal continues its operation as programmed. However, in instances of the latter case, such as New York City's, the buttons were simply deactivated when traffic signals were updated to automatically include pedestrian phases as part of every signal cycle. In such instances these buttons may be removed during future updates to the pedestrian signals. In the United Kingdom, pressing a button at a standalone pedestrian crossing that is unconnected to a junction will turn a traffic light red immediately, but this is not necessarily the case at a junction.
