3,000 Ride-Sharing Cars Could Replace Every Cab in New York City, MIT Study Says (theverge.com)
All 13,000 taxis in New York City could be replaced by a fleet of 3,000 ride-sharing cars if used exclusively for carpooling, according to research published today by MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL). From a report: Instead of hailing taxis, passengers that use ride-sharing services for carpooling may lead to reduced traffic congestion, pollution, and fuel use. The CSAIL researchers used public data from NYC taxi rides published by the University of Illinois to develop the algorithm. They calculated that 3,000 four-person vehicles travelling to similar destinations could meet 98 percent of taxi demand in the city with an average wait time of 2.7 minutes. Perhaps the most important part of the system is a dynamic repositioning of vehicles based on real-time demand, which makes the system 20 percent faster.
The major selling point of a taxi is that the backseat is all mine. Now I have to share a car with two other people, or a van with how many people?
No thanks.
If NYC people want to carpool, there is a fast, reliable, inexpensive carpool service. Its called the subway.
This makes a ton of sense in NYC which is already saturated with high capacity rail systems. If you made these car share vehicles self driving and electric, you have the potential for an amazing last leg solution.
Ride sharing (zip cars, and eventually automated vehicles) will be the future, but people do need to be aware in such a future, people will most likely not "own" cars any longer. But for this to work, they can only be a last leg. Ride shares and self driving cars will NOT solve the transportation gridlock problem. Cars simply do not have the capacity of real public transit:

"All 13,000 taxis in New York City could be replaced by a fleet of 3,000 ride-sharing cars..."
Gee, I wonder how many jobs that will create in this new glorious economy.
"...if used exclusively for carpooling."
That's one hell of a caveat to put on these efficiency metrics, given the amount of times drunk people not needing a carpool to work use taxi cabs.
There's already 35,000+ uber drivers in nyc.

Yes, but they're not following MIT's mathematical model. They're following real life supply and demand, the bastards. If they stop listening to supply and demand and start following mathematical models of where people theoretically should want to go, we would only need 3,000 of them.

Sounds like they just came up with a plan to use a bunch of smaller buses to replace taxis. What a novel concept.
Or the study was paid by Uber?
"Trump!!", the new Godwin.
Everyone pointing out the invalid assumptions of this study is missing the point. This research isn't about actually improving anything. It's about someone getting their MS or PhD and a couple professors getting their names on something to keep their publication rate up. Academia has no requirement for research to be useful. MIT is no different.

Nice to see someone try the math. (There are just over 13K cabs in NYC today.) However, this only works if one cab = one driver.
This could work... only if people would let it. The main complaint I see is ... but I don't want to sit with a stranger. What if these 3000 cars had individual compartments... complete with a comfy chair, newspaper/video of your choice, and a coffee? That might be enough for some folks. That plus having them dynamically allocated means not having to wait long and if you miss it/run late, schedule another one to pick you up.
and if there is an accident your on your own even more so with the GOP healthcare plan. You where in an taxi cash why should we have to pay out you need to sue the taxi co.
On/off cab driver here. Multiple pickups are my bane even though I'd make more money. Someone is always angry when they learn that they're not hiring a private car service, they got in a cab that (sometimes) takes multiple fares if they're going the same direction. Sometimes people are "no-shows" which sucks when everyone's trying to make their train on time. Then they want to haggle over paying the fare ("Then it should be split 3 ways." No, not how that works). Most are understanding and just want to get where they're going to.
Medallions cost around $1 million each. Do you really think a ten billion dollar asset is just going to roll over and play dead?
The person who came up with this is at MIT, which explains a lot.
The problem is, someone from MIT doesn't know the difference between theory and practice. In theory, theory and practice are the same, in practice, they are not.

Uber is not ride-share, it's just another car for hire. I mean how many times are you sharing your Uber with a stranger?
Sorry, teleporters just kill you and then make a copy. A perfect, soul-less copy.
So I don't see a total replacement of NY Taxis. What I could see is that there would be an impact. The one thing that would be need is that the ride-sharing cars be given exclusive parking spots. And you would need a phone app to open the doors and start the engines. My suggestion is that all of these cars be Electric.
New Yorkers need to know this secret!
It's probably a fake quote, anyway...
I see what you did here (please don't help to spread discrimination)
Well, let's simplify... 12,000 / 4 = 3000... Holyshit, I just figured out their entire study!
It will work out if the Taxis are spherical.
Uber offers a ride-sharing service, called UberPool, which combines trips for people traveling in the same general direction. If you use this option, which is cheaper than UberX, you would be sharing the car with strangers.
End of Line.
so taxi cabs becoming smaller size buses
really?!
who you you most like/hate to share a cab with ? Answers below please:
If you don't use qualifiers such as "could" and "might", then it comes off as a statement of fact, and not a prediction.
The wait time is only one variable, how about the length of the trip to the destination?
I have tried Uber Pool, and will never use them again. A trip that should have been 25 minutes point to point took over one and a half hours with Uber Pool, because the pickups/dropoffs forced the driver to stay on congested streets the entire way. Public transit would have been faster and cost 1/12 as much as Uber Pool. Even if this trip was more environmentally friendly than 3 passengers taking 3 separate taxis would have been, that comparison is missing the point. As a passenger, there is no benefit to using such a ride sharing service over public transit.
Let me know when a ride sharing service will be way faster than public transit, or when it when its cost and environmental impact will be comparable to public transit. I'm simply not interested in having the worst of both worlds.
And in a vacuum.
So it's sort of like a bus?
