Hey that's good that there is a Visual and Audible warning....our Pedestrial buttons don't work right...there was Even a Local News Story about it...the Button was Pushed on a Busy Road and the Pedestrial Signal Didn't Activate at all!
We have also Pedestrian Buttons in traffic lights system but with high brightness amber LEDs and without audible warning. I will post picture of them if i would can.
The council retrofitted almost all the CBD pushbuttons last year. The new buttond are big and beep to guide the blind, and buzz when it is green. Sadly most did not last the year, almost all failed due to either controller failure or vandalism.
I said that earlier(and there should be a link), any how welcome to GoL you have a great traffic signal collection, that is a lot for one button but I guess when the government is paying for them they don't really care
The ADA government act requires at the very minimum that all new crosswalk buttons be standarized with a 2 inch diameter actuation area. Whether cities follow it is another story... the polara buttons work well. I ended up getting their newest model for my setup which comes with the old version stainless steel button face or an embossed arrow. Works nice and the beeping/LED blink gets power from the existing detector circuit that a normal button uses. Navigator requires a control board for the voice and other options
What's a actuation area? Here the buttons are the size of the ones above but they're round and plain and silver with no special effects. It just does what it's supposed to do, trigger a "WALK" signal... Here's a pic of what the state of Rhode Island uses (remember, in RI the state is in charge of signals, not the municipality.)
actuation area is the area of the button that activates the signal, the silver part is 2 inches in diameter. The one you took a picture of is made by Pelco. I have that button as well but the sign I have is much smaller. It is like you say, the basic, press and get the walk signal...no fancy beeping or voice commands
There's some in the San Jose' airport that "chirp" loudly when activated (as you're crossing the road). And apparently there's some in Phoenix, AZ that count down audibly.
