Also, if you really want to learn about this, look at public transportation. It’s a wildly successful tool in reducing traffic and getting people where they need to be affordably. Some Transit Authorities are in partnerships with the city (MTA) while others are in partnerships with the state. My local TA, SEPTA, is currently at risk of slashing half of its services bc PA republicans (Joe Picozzi) refuse to fund it. This will add hundreds of thousands of cars back to the street.
