Eko stoplight by Damjan Stanković

From a link on the messageboard of Ken Jennings’ blog (from a debate about photocop): Eko stoplight by Damjan Stanković A red light with an implicit progress bar, just like on computers, so you know how long you have to wait. (one images similar for yellow and green lights). This might max dynamic/adaptive signal timings more difficult, but it could reduce driver frustration.
