Not so fast though. Comparing Paris to LA isn't quite fair. Paris is about six times denser than LA and therefore creating a competitive public transportation network is quite a bit cheaper there.

That's the problem with most american cities- grossly inefficient land use policy. Fix land use and effective transportation becomes an afterthought.

It's very hard to "fix" land use once the land is already "in use". Much harder than before the land is developed, at least.

LA seems to be doing the right thing: build subway lines/high-density transit, even if it "goes nowhere," and the density will follow.

I see this in Tokyo. Americans just stuck at home, stranded and helpless because of their culturally reasons. Oh no wait they just use the awesome public transport system. But it's very difficult for them to enjoy such efficience because...you..know...culture

Huh? Americans don't have a cultural aversion to using world class public transit when in a place like Tokyo. They have a cultural aversion to altering their cities in the radical ways that'd be necessary to build a functional public transit. They call this NIMBY.

It's not really even cultural. It is a socio-economic and technological issue. Every rich country that settled new territory or experienced massive growth after the invention of the car has cities that are spread out.

Europe was already developed pre-car. Asia had huge population growth when their people generally couldn't afford cars.

This is why US cities that were big before the Model T have a dense core with decent public transit. And cities that exploded after the Model T are basically suburbs of themselves, LA, Houston, Jacksonville. It's always why newly formed European suburbs often are just as car reliant as US suburbs. Though it's worth noting that some European suburbs existed before cars and at the time were just outlying cities that now got subsumed into the metro area.

If Japan had a new city naturally develop in an open area, it would a lot more like LA than Tokyo.

In India I experienced low tech ride sharing. You stand at an intersection and a three wheeler asks you where you're going. You get in, and the driver heads to a major intersection near your destination.

Along the way he asks other people standing at intersections if they are going his way, and if they are they pile in. The more people he stuffs into his three wheeler the more money he makes per trip.

It was an unpleasant ride.

I think America should look into the point to point system that Istanbul developed (and likely other places) called the dolmuş. These are 10 seat cars where people split the price to move along one line. (People will usually go end to end, but can get out along the ride as desired.) The route never deviates as to provide predictability. That said, most people take cabs because they don't want to be around other peopl…

This is a very common thing around the world: https://en.wikipedia.org/wiki/Share_taxi. And known in some places in the US, even!

And a grid of regular bus service could replace every car in LA. That'd be a harder sell though.

LA has a very underrated transport system. You can get pretty much anywhere, it just might take longer than by car, but only by an hour or two. Biggest hurdle is bus frequency, but even the routes on the hour are reliable and usable.

If they ran every 15 minutes, I'd never need a car! Having to wait 1/2 - 1 hour for a transfer sucks.

New York City includes Brooklyn, Queens, Bronx and Staten Island as well. Misleading title and perhaps incomplete study if footprint of cabs is not included from those remaining boroughs in this study. If you live in Manhattan, then you don't use cabs as much within Manhattan because subways cover Manhattan pretty well and travel times in cabs are hellish comparing to subway commute. You often use cabs when you commute to other boroughs from Manhattan because, for example, Brooklyn and Queens do not have great subway network.

Relaxing zoning to allow people to expand or rebuild more densely on existing lots would go pretty far in high-demand areas.

> You can get pretty much anywhere

there's a significant "last mile" problem for many of LA's single-family-dwelling neighborhoods. you get off the bus or train and then walk a long distance (or take Uber).

in limited cases (e.g. the underground red line) you arrive sooner than you would on freeways plus surface streets.

but in most cases, where there's a bus and a 1-2 transfers involved, it takes two or even three times as long to arrive.

one of the puzzles about LA's transportation planning is: they just spent about $1.6 billion to widen the 405's Sepulveda pass segment, which has at best modestly reduced commute times for car drivers, but historically, there's been little or no improvement to the corresponding bus service. the number of bus lines that run through that pass from the SF Valley to LA's west side is just way too low. and it's like: why? shouldn't bus line capacity have been the FIRST thing they improved?
