Feedback in Everyday Life
The simplest designs are often the most cleverest, this is definitely the case with the Eko Stoplight from designer Damjan Stankovic.
Designer Damjan Stanković came up with a concept where a timer is added to stoplights. Stanković promotes this stoplight as an eco solution in the following ways: If you’ve got the amount of time you’ve got to stop in front of you, you can shut your engine off, wait, be calm, and turn it back on again when the time is almost up. This not only lessens the amount of gas you use sitting still, but it lessens the amount of crazy madness you have wondering if the stoplight is stuck, or just really, really long.
When you think about it, you don’t need this information counted in seconds, you just need to see the speed of the progress bar to give you an estimate of the time.
Oour innate desire to see the bar creep forward runs deeper than our slow entanglement with computers. I wrote about this topic in another blogpost: The Psychology Of Waiting

There are examples of these in both Leiden and Amsterdam, but only for pedestrians and bikes.
Yea i have seen them too in Delft and Leiden. But they are not integrated in the stoplight but separated. Nonetheless it is a nice addition.
