Abstract
An accessible pedestrian signal system to assist visually impaired persons to cross a signal controlled intersection. The signal system has a push button which is pressed by the pedestrian. Circuitry is provided to vibrate the push button when the signal system is programmed to send a signal that it is time to cross the intersection. Preferably, the push button is mounted on a flexible diaphragm and a vibrating movement is transmitted to the inner surface of the diaphragm when it is desired to vibrate the push button. Preferably, the pressing of the button flexes a piezo-electric member which has an output to the circuitry of the signal system.
