It turns out that public transit is extremely important for reducing traffic. Because the relationship of traffic and congestion is extremely non-linear, a shutdown of transit can cause massive increases in congestion -- justifying substantial subsidies for trains and buses. 1/

tThis is a methodologically simple paper, but very clean. In October 2003, the LA public transit workers went on strike for 35 days. We can consider the change in congestion, after sanity testing it, to be the effect of the MTA.
During peak hours, the average delay increased by about 50% relative to what free-flowing traffic would be. That's (roughly) going from 1:24 per mile to 1:36, or the equivalent of making a 28 minute commute last 32 minutes instead.
That's for traffic everywhere, though. Traffic along roads where the subway ran saw much starker changes in travel time.
The implied benefit of transit in 2003, just from reducing congestion, was somewhere between 1 and 4 billion dollars a year!

Nicholas, I'm a Transport Economics student in Amsterdam and I wrote a paper on this topic where I came to a very different conclusion. Can I dm you a copy of the paper?
I’m always telling people how the terrible train in LA that nobody rides is actually super valuable
Do you think part of the reason why public transport provides such high benefits via reduced congestion is mainly because we don’t charge for road use effectively? If so, whats better for efficiency - better road use charging or public transport subsidies?
Good to see that this working paper was also published in a peer reviewed journal jstor.org/stable/43495332
A shutdown of private housing would overload public housing projects. Therefore, private housing should be substantially subsidized.
A shutdown of private schools would overload public schools. Therefore, private schools should be substantially subsidized.
A shutdown of health
And if you care about public transit, you should support enforcement of laws against the fraction of people who ruin public transit
If autonomous buses make transit's unit costs fall, should we expect falling congestion?
Public transit is a nice, warm, moist Petri dish. Make sure to wear an N95 mask, eyewear and disinfect your hands after you exit.
It actually does nothing because 85%+ of the time there are very few riders of my local buses.
We are fortunate fewer people take public transit in the US than 20 years ago despite population growth and trillions invested
Its a last resort for those who have no other choice but to ride with the homeless
"It turns out that public transit is extremely important for reducing traffic."
no way
No it doesn’t. The conclusion is false.

The analysis is completely flawed. It draws a general conclusion from a fixed system under unsustained unusual conclusions. The transition stopping was temporary situation, and the system did not change.
This happened, but the conclusion is a local trucan in space and time: a lie
