I always thought there should be some line, marking, or sign that conveyed "if the light turns yellow before this line, at the posted speed limit you will not make the light" because it can be a hard call most of the time.

In Canada at least, some intersections (generally on major thoroughfares) have a “prepare to stop” light well ahead of the traffic light. If that light is flashing, the traffic light will be yellow or red by time you get to it. Of course, some people use this light as a reason to floor it to try to make the light...

Newer traffic lights where I live will flash the green light for a few seconds before turning amber.

We have that in Austria since decades. It works great. They tried without the green flashing but reverted a couple of years back to flashing.
