Is a Progress Bar on a Traffic Light a Good Idea?

traffic light progress barA design award has been given for a concept that would allow existing traffic lights to be retrofitted with progress bars that offer a visual representation of when the light will change. Several benefits have been suggested…

- Less pollution, as drivers can turn their engines off and cut carbon emissions while waiting for the green light,
- Less fuel consumption, as turning off vehicle engines lowers fuel consumption in the long run,
- Less stress, since drivers know exactly how long to wait, and
- Safer driving, as all traffic participants are fully aware of how much time they have left before the light changes, reducing the chance for potential traffic accidents.
