This IMO is the best ongoing study of NYC congestion pricing. An update w/data thru 6/26 is encouraging: "The toll raised cordon-area speeds by 11%, with little effect on air quality, consumer spending, or foot traffic. Speeds also rose outside the cordon." shoshanavasserman.com/papers/the_n...

As expected, drives into Manhattan grew notably faster following congestion pricing. But local journeys outside the toll zone also sped up a bit – and there are *lots* of them. To the researchers’ surprise, those driving outside Manhattan collectively saved 5x more hours than toll payers(!).

An analysis of the first 2 months of New York City's congestion pricing policy shows that road speeds increased and emissions decreased inside and out of the congestion zone, from Cook, Kreidieh, Vasserman, Allcott, Arora, van Sambeek, Tomkins, and Turkel www.nber.org/papers/w33584
