I like this; it's smart. It's a low tech solution that simply coordinates transit based on demand and self optimizes to serve that demand.

The value of buses and trains running on schedule is mainly that you can plan around it. But what if transit worked like Uber. Some vehicle shows up to pick you up. It might drop you off somewhere to switch vehicles and some other vehicle shows up to do that. All the way to your destination (as opposed to a mile away from there). As long as the journey time is predictable and reasonable, people would be pretty happy with that.

I think this is one of those ideas that sounds good on paper but breaks down in practice.

One immediate problem that comes to mind is that you need a smartphone to take public transit. So if there's a teen without a smartphone, they can't take the bus, nor can someone who's phone died, etc.

One of the amazing things of the current system, as simple as it is, is that it's predictable and doesn't require coordination. You can walk to a bus stop and know that a bus will arrive and take you where you expect to go, same as the last time you've taken it and the time before that. You don't need to look up a map to see what today's route is, or to see where the stop is, or to let the bus know you're waiting for you. You just show up at the bus stop and the rest just happens in a predictable and reliable fashion.

Yes! Just use an app to say where you want to go, and it tells you which of the 3 nearest bus stops to go to, and you get where you want to go reasonably quickly. No bus routes, just dynamic allocation and routing based on historical and up-to-the-minute demand.

If you tell the system your desire well in advance, you pay less. "I need to be at the office at 9 and home by 6 every weekday". Enough area-to-area trips allocate buses. Smaller, off-peak, or short-notice group demand brings minivans. Short-notice uncommon trips bring cars. For people with disabilities or heavy packages, random curb stops are available.

Then you remove private cars from cities entirely. Park your private car outside the city, or even better, use the bikeshare-style rentals. No taxis or Ubers, only public transit, with unionized, salaried drivers. Every vehicle on the road is moving and full of people and you can get rid of most parking spaces and shrink most parking lots.

It's not rocket science. It's computer science.

Fantasy, because it would allow us to drastically reduce the manufacturing of automobiles.

In various countries there are private vans that ride along the normal bus routes, marked with the same numbers as the buses. They work exactly like buses, collecting and leaving people at the stops, but they're much smaller and usually more frequent. I always thought they were an excellent solution- I don't get why there shouldn't be anything in between big, rare, and shared public buses and small, on-demand, individual private cars.

I had to do a visa-run in Vietnam a couple weeks ago and my trip to the border was exactly like that. After the bus got to their nominal final stop, they’ve unloaded all passengers except me, then made a couple other stops (they took a computer monitor from one place to another??), then finally told me to wait and take another bus, which I didn’t have to pay for. (Both buses were of the micro-bus / marshrutka kind, of course.)

That "What if" is a stupid idea that has been around for years. Professionals have written about this extensively - https://humantransit.org/category/microtransit for example. The fundamentals mean it can never work for anyone anywhere - including aliens with some arbitrary advanced technology.

You cannot combine fast, predictable and reasonable journey times with reasonable costs unless you have a scheduled service. If you want a chauffeured limo that is fine, don't pretend it mass transit or in any way better than a private car for anyone other than you.

My area has a dial-a-ride service where you can schedule a ride and they essentially make an on demand bus route for it. I've never actually used it though because it's just really not convenient. You have to call a dispatch number to schedule trips like 3 days in advance, and can only cancel 24 hours before your trip. And you can only schedule trips on certain weekdays (doesn't run on weekends at all) depending on which city/town you're leaving from or going to.

Even with regular, fixed routes, I've for some time argued the transit operator really need booking apps, on the basis that you really need the data on the full journey, and it'd transform e.g. bus routes if you could offer "there'll be a pickup within X minutes", without necessarily having the buses for it by falling back on renting cars. If you make people give their end destination, you can also do much like what the article suggests, but semi-automatic based on where those on the bus (and waiting at stops) are actually going right now.

Today, ridership gives hard data on where people will go and when given the current availability. Offer a guaranteed pickup, and you get much closer to having data on where people actually would want to go, and even more reliably than people voting on a "wouldn't it be nice if" basis.

Via Transportation (ridewithvia.com) started out doing pooled cab rides but pivoted to doing what you describe, seemingly successfully. Lots of value for school transit, para transit, etc as well. I have no affiliation with them but I think the model is very promising.

We're piloting VIA Link in San Antonio, TX to add on last mile Uber style from transit stations.

Roads to not have unlimited bandwidth. I think this _is_ a good idea, but has to have some boundaries on how it functions or you will gridlock your city by accident.

This will never work in US for two reasons:

1. removes control from local authorities - "we are supposed to decide for our citizens, not them"

2. NIMBYs will oppose the bus passing on their street - "too much noise, peoples, ..."

It's like rethinking buses not as rigid lines, but as flexible, scalable logistics
