The order in which the lights change]]>Nov 22nd 2008 2:16PMhttp://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/http://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/
They see which of the three is lit up. That's why each color has its own light and why it's not just one light changing color. If you have three lights and always accept that, say, the top one is always 'stop' and the bottom is always 'go,' you don't need them to be different shapes. You just see which in the pattern is lit and you act accordingly.

For shapes to need to be in the equation is to suggest that either the order itself can change (square, circle, triangle on Monday/circle, triangle, square on Tuesday) or the three shapes/colors originate from one display. I'm not familiar with the lights in Quebec, obviously, so can you tell me which it is? Or am I missing something entirely? ]]>Nov 22nd 2008 2:26PMhttp://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/http://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/Nov 22nd 2008 2:39PMhttp://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/http://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/Nov 22nd 2008 3:02PMhttp://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/http://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/

Big wow led traffic lights]]>Nov 22nd 2008 3:28PMhttp://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/http://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/Nov 22nd 2008 4:21PMhttp://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/http://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/
"Lebedev's team asserts that using square lights backed with bright laser diodes would make better use of the available space and provide a more noticeable signal"

I wont say fail, but this is not a very convincing argument.]]>Nov 22nd 2008 9:17PMhttp://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/http://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/
We color-blind folks don't need special shapes.

Meanwhile there is a thread on the Tufte forum questioning the design of traffic lights:

1) maximum diffusion through the curvature of the lens

2) The round seal is much more better to keep out rain and moisture

3) Safety reasons. If a square piece of glass hit you.. well

But thought that all lights would be replaced with LED equivalents... less maintenance and less energy...]]>Nov 22nd 2008 12:19PMhttp://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/http://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/Nov 22nd 2008 12:42PMhttp://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/http://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/Nov 22nd 2008 1:33PMhttp://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/http://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/Nov 22nd 2008 1:46PMhttp://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/http://www.engadget.com/2008/11/22/art-lebedev-outthinks-the-room-with-square-luxofor-traffic-light/
and about LED traffic lights: They just revamped the downtown area where I live including new LED traffic lights.

And yes people, all over the world they are already introducing LED traffic lights for some time now, no need to state the obvious.
