Not sure if this is out in all areas yet.
Anyway, I was walking back to the office today and I noticed a funny sound comming from the stop lights. It sounded kinda like a bird chirping, but it was clearly an artificial sound. It took me a moment to put things together, but then I realized the sound came on every time the "cross" light came on.
At first I was puzzeled, it didn't make much sense. I can clearly see the "cross" signal light, hearing the sound didn't really offer anything beyond what I could see with my eyes. Then it dawned on me! It's for the blind.
Apparently here in VA they are working on making the roads safe for blind drivers! I should have seen the connection right away, because I have noticed brail at the drive-thru ATMs.
The sound is to warn blind drivers that pedestrians are crossing the crosswalk!
