Probably some mixture of the following tactics.

## Fix the subway (by which I mean make it more like Japan's rail):

  * Make loitering illegal, enforce it
  * A 'short loop' everything recorded space
    This is anti-vandalism / for crimes within a day
  * Since this is the US, safety barrier the train
  * In-city Automated circuits, automated schedule.
There'd also need to be baked in maintenance, but I'm not an expert in subway repair so I'm not sure what's actually required vs nice to have. If the subway is down, surface buses should run to replace it.

## An interface between the subway and the rest of the world:

Large parking silos close enough to the city to be on the subway grid (with good service), BUT, far enough out to have good use of the land. These too should have somewhat short loop subservience for security (maybe a 7-day rotation here). Parking can be charged for, but it should be less than the cost of having an automated driver take you in to the city, drop you off, and pick you up later.

## Every-day Freight backhaul:

As a transportation utility, during the more downtime hours the subway could be used by semi-automated transport cars to route pallets (or a replacement transfer unit) of things classified in several storage classes: Frozen, Refrigerated, 'room temp', not conditioned, 'special'. (Special being an un-conditioned, but ventilated with normal air, room that provides power for local regulation.) The transfer pods would be ferried along normal subway lines between cars during the downtimes. The stops would probably mostly be off of the normal ones, but exceptions might be made. Nearby storage rooms would receive the contents and buffer them. Those rooms are a city owned public utility (somewhat like paid parking spaces are now). Again, subservience on short loop, with added restricted access via RFID fobs and needing to show faces. Automated logging of who's checking in and which pallets they're taking out. At this point they may be close enough to hand/forklift transport, or maybe form an airport luggage style electric powered tram delivery.

## Reducing friction of desired transport methods:

Probably the free# (for people; #paid for with taxes) transport, and keeping the costs of the last-mile backhaul minimal for commercial ideas would be the biggest reduction. The increased patrols, and automated subservience backup (to trace fault after humans identify issues) are also supposed to reduce friction. In the narrative I've setup the civil enforcers are only supposed to be providing help, not hassling random people asking for papers.




I'm not sure any of your "Fix the subway" suggestions does anything useful except the last one, which isn't as easy as it sounds.


make it more like Japan means privatizing the public transportation and giving the companies running the lines the ability to buy and own real estate in and around the stations as well as not giving all lines to one company
