They put in an algorithm (AI) traffic control system here on a stretch that
they never could get lights manually right, a couple of the intersections
there a train track, multiple employers shipt change overlap, highway off,
etc. Has been a mess since I was a kid.

Now it's a rarity to see traffic backed up to the next intersection, way
less downstream fender benders, generally smoother traffic patterns since
the lights can all coordinate in real time based on dynamic flows and
whether a train is present or not.
