I’m not convinced about that. Firstly, in reality, the same people are sitting each and every day in the same traffic jam. They also do not take in account that the route they take is the slowest at that time of day, but they took it anyway.
I have the impression the cross road management is bad. Cars get too easily stuck in a simple deadlock, while trying to turn. And, once a jam notices it is waiting for itself (eg around the block) it should pull out cars, which turn around and look for another path.
But I think that the installation of the announced traffic lights might bring some slack in the jam… I hope so.
