- Great point. If the concept behind this is that it will relieve stress, I would like to see some solid studies done to prove the following:
First, that the current system creates some inherent stress in and of itself. We would need several baselines for participants. Stress levels when not driving, stress levels while driving under various scenarios, and stress levels while waiting at the current red lights. If stress levels at lights are higher than they are elsewhere, then we know there is indeed a problem to be solved.
Second, the studies would need to determine the effects of the new system on drivers' stress levels. If the stress levels at lights are shown to be significantly lower, then they may be on to something.
I think additional studies would need to be done to determine the lights' effects on people running lights, the frequency of accidents, and overall drive times.
