Actually can you just put traffic-triggered off-by-default red lights, similar to the ones used on highway on-ramps to trickle cars in during rush hour?
If only one or two cars are seen on the road, turn the light off. If more than that, turn it on and allow one car per green every several seconds. It will reduce throughput enough that Waze will automatically route away from it (and eventually Waze editors will have to figure out how to encode it) without affecting normal residential traffic.
For whatever reason, people don't always care about speed limits but they usually don't run red lights.
I don't understand why "on-ramp" metered lights aren't used in many more places.
Like enforcing easy zipper merging. Put lights on both lanes that need to merge together, out there in the middle of the freeway. Turn them off when there's no traffic.
That is interesting... metered off ramps. I could see them putting one at the Eastbound 101 exit for Haskell. I see very few people exit there while I'm stuck in traffic waiting to get on the 405. I'm sure a significant number of people are following waze (it often suggests I go that way to save 4 minutes).
