Re:$30 Toll to Use Express Lanes

I know nothing about this implementation, but I'd be extremely interested into how the pricing model adjusts itself.
I'd assume there has to be some delay built into the system to measure the impact that price increases have on user take up and lane speed, however it seems in this case that when delays increase faster than the model can adjust its pricing you get to a point where it fails to work (ie nearly at a standstill)

I would be interested to know as well. It certainly seems difficult in some cases, and this is far from the first time I've seen the express lanes below the "guaranteed" speed. It usually works pretty well, but not always.
