Are there audible crosswalk signals?
Yes. These signals emit a chirp, ringing, or recorded voice to assist visually-impaired pedestrians. They are often found on college campuses. Aug 23, 2002 11.8 Q: Where is that upside-down signal? A: The most famous inverted signal is in the Tipperary Hill neighborhood of Syracuse, NY. See http://www.empirestateroads.com/photos/onondaga/ , http://www.roadgeek.org/waste_of_film/page2.html , http://www.gribblenation.net/nypics/tipperary/ , and http://cny-signals.tripod.com/en/syracuse/tipperary_hill.htm for details. There is also a green-on-top signal on MA-3A in Billerica, but it is not an inverted signal; rather, it is a five lens vertical left turn signal without the red and yellow circular indicators, leaving only green, yellow left arrow, and green left arrow, from top to bottom.
