Progress bar is almost synonymous with almost all modern operating systems. It helps you realize at what point of the process you are in and gives a decent estimation for how long a process will continue. Now, designer Damjan Stanković is thinking of putting the same idea on traffic stoplights. So the the next time you see the red light, you know for how long you have to keep on waiting.

Ofcourse this is still a concept, but we will not be surprised if we soon see something similar in production.
