Atlanta has rolled out variable speed limits on some highways (I285) which attempt to slow down the flow BEFORE people reach the congested area.
I'm not sure how well most users understand how it's supposed to help them go faster by slowing down; a bit more education could be helpful so everyone plays the game.
It is a bit weird seeing the speed limit jump from 45 to 65 then to 35 within the space of a mile…
These are very common in the UK around large cities, and in my experience they work really well. As long as there's sufficient threat of enforcement (speed cameras), people stick to the speed and the whole mass of cars move along at a reasonable speed. Compared to the horrible 80 mph, 5 mph, 80 mph, 5 mph thing you get when everyone absolutely guns it to the next slowdown they're brilliant.
