So, you make the yellow phase last long enough to cross the entire junction 
at the slowest speed you can imagine for that junction?  I guess that would 
work, but then when the road is flowing normally, people would just continue 
to drive through on yellow, knowing that it is going to last for 5 seconds 
or whatever, when the whole point of yellow is for you to stop if it's safe 
to do so.

In China I saw a few lights where they had a big 7-segment countdown timer 
above the lights, looked like a pretty cool idea, well it would have been if 
they paid any attention to the lights in the first place :-)
