[Electronics-talk] Electronics-talk traffic signal app

[Jim Barbour]

Hey Sarah,

I hear you that I probably sound like I'm judging.  I do think it is not a smart thing for blind people to rely on APSs, except in rare circumstances where the number of points of an intersection are very high, or some other one off traffic situation.

Being deaf/blind has been mentioned as a reason to rely more on APSs. Not knowing much about how those who are dead/blind travel, I completely respect this option.

Would you mind answering another question for me? This was asked the other day, and it still is a question I have. Why do you care if it is quiet because there's no traffic, or because the signal is in your favor?  What are the circumstances when you wouldn't just obey the rule that if it's quiet, you would cross.

Thanks Very Much,

Jim
