Don't you have indicators? In Spain the buttons (which BTW are increasingly uncommon, cars lost the battle) have two large indicators, lit depending on the state:
- Please press
- Wait for green
- Please press
- Wait for green
However others have no indicator or sound. To make things even more confusing is the pedestrian crossings can also be programmed to happen automatically at peak times with no button press, but absolutely need a button press outside of peak hour.
At least that's the way it is here in NZ, and when I've been in Sydney, Melbourne and Brisbane I haven't obviously noticed a general difference to here in NZ (there are particular crossings that are sometimes a bit different, i.e. you never need to press, but)...
Feedback would obviously solve (or at least alleviate) the problem I mentioned. It would, however, be much less amusing.
