Study explores how blind pedestrians can cross safely

I spotted this article, Study explores how blind pedestrians can cross safely, in the Triangle's News & Observer. "Walk faster" does not seem like the best technology for pedestrians, never mind visually impaired ones.

VisionWalk

This year I am doing the VisionWalk (http://www.visonwalk.org/) fundraiser for the Foundation Fighting Blindness. The FFB does research on several vision disorders, including mine. If you have a few dollars to spare, please consider sparing some. I have a Visionwalk page at http://www.fightblindness.org/goto/tco . No pressure!
