Surely congestion is caused by too many vehicles at one place at the same time? If Some of the vehicles are removed, then there's less congestion.
There is this crazy idea that people must work 8-4.30, or 9-5, and of course don't forget the mommies taking the brats to school at about the same time. By me congestion stops at 9.15, the roads are relatively quiet till 3.30, then madness till 6pm.
So the simplest solution is to stagger work times, but this of course wouldn't generate any money for Mr Brown would it?
Make sense?
