[Electronics-talk] Traffic signal app

[Tracy Carcione]

Someone said they'd heard about work on an app to identify when a traffic
light was walk or don't walk.  Anyone know any more about this?  I keep
thinking how useful that would be.  As I'm getting older, I don't hear the
traffic changes as well as I used to.  And an app seems a lot cheaper than
putting in audible signals.  And I keep hearing about traffic signals having
all kinds of "smart" things built in, so maybe an app could build on
something already there.
