Designing traffic flow

Ready, set, go ...

"Interesting approach to turn signals. Mendota Heights (near St. Paul, MN) is testing a "flashing yellow arrow" turn signal. The article says it's "first of it's kind," but haven't I seen this before? Does your city use this?

What do you do when you see a flashing arrow? We're used to the flashing (solid) yellow light and know it means "proceed with caution," so I don't think this is too much of strecth to apply it to turn signals, but you never know.

Anyway- you don't see a lot of innovation taking place in traffic signal design, that's probably for a good reason. At least it's not as bad as the "reversable lanes" you see... where in the morning you drive down it with a green arrow pointing down to your lane, but in the evening it has a red "X" in it. That might seem a little more jarring."   (Continued via User Centered)   [Usability Resources]
