Traffic Light Idea

Traffic Light Idea Dave Delisle

They already use arrow shapes for traffic lights (turn signals) and person/hand shapes for pedestrian crossing lights, so why not assign specific shapes to the standard traffic light? Red would be represented by an octagon shape, already established in its use for stop signs. Amber would be represented by a triangle or a diamond shape, which is often used in symbols of caution or warning. Green would still be circular. I’d like to see the red stop light being larger than the other two, to give the impression there is greater emphasis to stop than the other two. While I would like to see these implemented at every intersection, it may be worthwhile to install these only at intersections that have a high accident rate. Approaching the odd intersection equipped with different-looking lights may increase the attention of drivers. This system would assist colorblind drivers as well.

  1. How about blacking out triangles at the bottom, top, left and right of the octagon so that you have a big red X for the stop light.

    1. An “X”-like shape would be easy to translate as stop, so that is a decent option. As long as the X is a big bold shape, not a couple of thin lines intersecting – needs to be seen from afar.

  2. Wow – funny how RED= Octagon or “X” or square (max size) , AMBER = triangle, and GREEN = circle was exactly what I thought of for my family of colorblind sons. I can’t believe we let tons of metal travel past each other at life-threatening speed on the basis of COLOR alone. We don’t even do that for a harmless webpage.The other mind-blowing thing about all this is that the transition from globes to LED’s was the perfect opportunity to make the switch.
    The other (super simple) option I had was make all green lights arrows. (we have them already). This way “GO” is always relatively faint. (But this might be an issue when GO should allow turning also- which leads to multiple arrows. But then, these are usually ‘safe’ or simple single lane intersections, so they could get a circle for GO). And another possibility is to utilize flashing or animation (assuming LED’s of course).

    But one would assume this has all been studied hundreds of times in exhaustive scientific studies for the millions of colorblind drivers and the millions of traffic lights, wouldn’t one? I mean, they should have spent, um let’s see, about $10 million on the research and testing roughly…Surely…
