I'm pretty sure it depends on the location, who installs and "owns" the light, etc. I know that there are traffic engineers who make a living working out traffic routings and such, but I'm pretty sure they don't work everywhere.
Many lights don't seem to be timed at all. Others are obviously connected to other lights. Still others are "locally" controlled by magnetic induction loops in the road.
