If there are two crossings next to each other where either can be on green while the other is red, the noise wont be there. It's to make sure that someone waiting at the red crossing does not hear the noise and cross. I think the article mentions that somewhere.
- itsybitsycoder 13y agoThe intersection crossings in my hometown and in my current city all have noise. They just use different noises for the different directions. E.g., N-S crossings might chirp while E-W crossings might beep. (I don't remember exactly what the rule is, but I'm sure a blind person would.)
- joeblossom 13y agoAt my university, they'd make the chirping noise, but it'd also state which road has the walk sign. So it'd repeatedly say "Farm Lane Walk Sign" while the sign was on.
