It's not always possible to stop safely for a yellow light, especially if one is close to the intersection. Yellow lights should last long enough for a typical vehicle traveling at the speed limit and within some distance of the intersection to proceed into the intersection and make a complete (legal) turn.

That's exactly the idea behind the revised formula. (Which is an evolution of an earlier, similar formula that only considered the time to proceed straight through.)
