Transit and Traffic Congestion

I hate to break it to you, but there is nothing that can be done to reduce traffic congestion. Some combination of the triple convergence and induced demand puts paid to any new highway capacity, and usually pretty quickly. 

The same is (sadly) true of transit. If my transit capacity reduces traffic congestion, the triple convergence still strikes: people divert from other times, other modes, and other routes, until traffic congestion reaches equilibrium again.
