Has anyone come up with a GPS that would help blind people?

There is this incredibly brave blind man that I see walking around. He crosses one of the busiest intersections in this part of town all by himself with just his white cane.

And I got to wondering if there was a way to use GPS to help these people get around easier.

1. The map app on my cell phone will give voice directions

...however, it won't warn me if a car is speeding towards me.

2. The cane helps determine what the footing is, not just where you are. It also serves as a notice to

others that you have vision issues so they will hopefully give you a bit of room.

3. GPS just tells you where you are in relationship to the Magnetic poles & latitude/ Longitude

coordinates. Not with what you are in danger of colliding....
