New York City was supposed to terminate its congestion pricing program last Friday because, well, Trump told them to. But they didn't do it and so harsh words were exchanged and then the deadline was extended for another 30 days. (This sounds oddly familiar.) Who knows what happens next month, but we are able to accurately quantify the benefits of nearly 3 months of congestion pricing.

Firstly, it's generating a lot of money. In the first two months of operation, congestion pricing has already brought in over $100 million in new revenue for the city. This is important because it's money that can be used for transit and other infrastructure improvements.

Equally important is the fact that this money was generated by creating measurable value for drivers. For all of the river crossings that lead into the CBD, average weekday travel times this past January are lower compared to January 2024. And in some cases, they're lower by a lot. The Holland Tunnel, for example, saw travel times drop by 48%.

Lastly, it's encouraging more people to take public transit. Here's a chart from Sam Deutsch over at Better Cities showing the increases in ridership since the program was implemented:

The MTA as a whole is now averaging about 448,000 more public transit riders per day. And to put this number into perspective, Sam reminds us that Washington DC has the second most-used public transit system in the US and that it sees an average of about 304,000 total riders per day (January 2024 figure). So in other words, New York's congestion pricing bump alone was nearly 1.5x DC's entire ridership base.

Some critics will argue that NYC's subway is dangerous and that this program unfairly pushes people toward it. But crime data suggests otherwise. New York's subway also saw over a billion rides in 2024! So I don't know how you argue that less people should be taking it. It's pretty clear that this is what moves the city. Imagine if the above went the opposite way and 448,000 more people started driving to work.

Some people may not like it, but the reality is that congestion pricing is doing exactly what it's intended to do: reduce traffic congestion, make money, and encourage more sustainable forms of urban mobility.

Today is the third day of New York's new congestion relief zone. And if you're curious to see how it's already impacting traffic conditions, here is a website run by Joshua Moshes and Benjamin Moshes, under the supervision of Brown University Professor Emily Oster.

The site collects Google Maps traffic data every 15 minutes for 19 routes leading into Manhattan (some of which are directly affected by the new relief zone and some of which are not). It then calculates average traffic times for each day of the week, both before and after the congestion charge.

Here is the Holland Tunnel on Sunday (which was day number one):

And here is the Holland Tunnel on Monday (which was the first weekday):

Already, we are seeing a meaningful reduction in average traffic times. Maybe demand is more elastic than I suggested yesterday. But obviously we're only looking at two days. So I'll check back in later once we have more data points. In the meantime, if you'd like to follow along, you now have a website.

I first wrote about Manhattan's proposed congestion charge back in 2018. Naturally, some people supported it and some people opposed it. Four years later, it was reported that the charge was still being considered for the area of the island south of 60th Street, and that it could generate an additional $1 billion in revenue for the city's transportation authority. But then in June of this year, right before the charge was set to come into effect on June 30, 2024, New York Governor Kathy Hochul said "nah, let's pause this indefinitely." And at that point, it felt mostly dead.

Nope: A revised tolling plan has just been announced -- the charge has been reduced from $15 to $9 -- and Hochul is now trying to jam it through before Trump takes office in January. Trump opposes the charge and has branded it the "most regressive tax known to womankind", so there's a real deadline here. This could get interesting. Do you think it will actually happen, some 6 years later? (In reality, the timeline is far longer. Congestion pricing also looked promising during the Bloomberg era, but then similarly died. And I'm sure there were even earlier proposals.)
