Komanoff and writer Felix Salmon get particularly wonky with the stats in this article - transportation planners will find a lot to chew on.
"Medallion taxis do not pay the congestion charge, but there is a 33% taxi-fare surcharge. One tenth of that (around 3%) goes to the taxi drivers and owners; the rest (30%) goes to the MTA; the taxi surcharge alone raises enough money to make in-city commuter rail free.
Add it all up, and it's pretty much revenue-neutral, says Komanoff: the biggest line items are that you lose $1.46 billion in transit fares, while gaining $1.31 billion in congestion charges. But total time savings are the biggie: implement this plan and New Yorkers get over $2.5 billion of time back which would otherwise be spent wasted in traffic. Vehicle speeds in general rise about 20%, and as much as 25% between 9am and 10am."
