Editing Traffic light (section)

===Auditory and tactile signals===
In some jurisdictions such as Australia, pedestrian lights are associated with a sound device, for the benefit of blind and visually impaired pedestrians. These make a slow beeping sound when the pedestrian lights are red and a continuous buzzing or fast beeping sound when the lights are green. In the Australian States of [[Queensland]], [[New South Wales]], [[Victoria (Australia)|Victoria]], and [[Western Australia]], the sound is produced in the same unit as the push buttons. In a circle above the button on a [[PB/5 pedestrian crossing button|PB/5 crossing]], the sound is produced and can be felt along with a raised arrow that points in the direction to walk.<ref>{{Cite web|last=Park |first=Miles|title=Sublime design: the PB/5 pedestrian button|url=http://theconversation.com/sublime-design-the-pb-5-pedestrian-button-26232|access-date=19 December 2020|website=The Conversation|date=29 June 2014 }}</ref> 

This system of [[assistive technology]] is also widely used at busy intersections in Canadian cities. In the United Kingdom, the [[Puffin crossing]]s and their predecessor, the [[Pelican crossing]], will make a fast beeping sound to indicate that it is safe to cross the road. The beeping sound is disabled during the nighttime so as not to disturb any nearby residents.<ref>[http://www.2pass.co.uk/crossing.htm#.T194QfUZlGM Types of Pedestrian Crossing in the UK]. 2pass.co.uk.</ref> 

In some states in the United States, at some busy intersections, buttons will make a beeping sound for blind people. When the light changes, a speaker built into the button will play a recording to notify blind people that it is safe to cross. When the signal flashes red, the recording will start to count down with the countdown timer. In several countries such as New Zealand, technology also allows deaf and blind people to feel when lights have changed to allow safe crossing. A small pad, housed within an indentation in the base of the box housing the button mechanism, moves downwards when the lights change to allow crossing. This is designed to be felt by anyone waiting to cross who has limited ability to detect sight or sound. 

In Japan, a traffic light emits an electronic sound that mimics the sound of birdsong to help the visually impaired. Some traffic lights fix the order and type of sound so that they can tell which direction is a green light. In general, "''Piyo''" (peep) and "''Piyo-piyo''", which is a small bird call, and "''Kakkō''" and "''Ka-kakkō''", which is a cuckoo call, are associated with this system.<ref>{{Cite web|title=横断歩道、減る「通りゃんせ」 音響信号「ピヨピヨ」化：朝日新聞デジタル|url=https://www.asahi.com/articles/ASJ9N3VTNJ9NTIPE00Z.html|access-date=1 September 2020|website=朝日新聞デジタル|language=ja|archive-date=6 November 2020|archive-url=https://web.archive.org/web/20201106132038/https://www.asahi.com/articles/ASJ9N3VTNJ9NTIPE00Z.html|url-status=dead}}</ref> Some pedestrian crossings in Lithuania make a slow beeping sound indicating that the traffic light is about to turn off.
