Some economists at Vanderbilt used the introduction of Boro cabs (green cabs) to estimate the effect of an additional for hire vehicle on traffic congestion. They claim that most of the increase in Midtown Manhattan traffic congestion is due to Lyft/Uber[1].

- adwww 6y agoSame in London - it feels like almost every vehicle on the road is a private hire Uber in central London.
- chrisseaton 6y agoThat's a good thing though, right? We want more people using taxis rather than their own cars.
- londons_explore 6y agoThe benefits for society aren't clear-cut. The taxi has to drive around between fares, increasing congestion for no benefits to the wider economy. Also, so far taxis are still all driven by humans. The economy only has a fixed number of humans and needs to allocate them to the most worthwhile things. Having two humans (driver and customer) in a vehicle travelling to a place costs society more than having just one person doing the driving.
- chrisseaton 6y agoBut it's 1 taxi to 100 people or something like that. Compared to 100 cars to 100 people. Can you imagine what London would be like tomorrow if everyone suddenly took their car to work? It'd be completely intractable. Nobody would even get near the city centre.
- londons_explore 6y agoA taxi is still one per person at any point in time. The only difference is the amount of parking needed. Had the city been built for that (ie. A few floors of underground parking under every building) it would be fine. Some cities in Poland do this. Clearly retrofitting that isn't practical.
- chrisseaton 6y ago> (ie. A few floors of underground parking under every building) Have you actually thought this through? For example - 6,000 people work at the Gerkin. Can you guess what area is needed to park 6,000 cars? How many underground levels you'd need? How long would it take cars to filter in at the start of the day and filter out at the end? How much road space you'd need for everyone to get to the building in the first place? It's 90,000 m^2. That's about 90 underground levels you're building there, or digging twice as deep as the building is high. Your idea is insane.
- rienbdj 6y agoYou appear to be shadow banned, but this comment is spot on. Cars do not scale well in urban areas because the space taken per passenger on the road (and when parked) is far too big.

- iso947 6y agoIt would look similar to if everyone went by cab (parking aside) In dense areas we need everyone going by space efficient transport (walking, tubes or buses if they are full, maybe bikes)
- 9HZZRfNlpR 6y agoWhy? Single person still in the car (plus uber driver), city still congested, polluted, co2 the same or maybe worse. What's the difference?
- chrisseaton 6y agoLess cars have to be produced, maintained, driven in, parked, driven out, scrapped. All-round win.
- bluestreak 6y agoThis formula breaks down when you have a kids that go to school and worse still, two separate schools. Not everyone can hop on a bike.
- chrisseaton 6y agoAre you replying to the right thread? We're not talking about bikes here. We're talking about cars vs taxis.
- adwww 6y agoIt's a good thing that it isn't private cars, sure. But I'm not convinced of the merits of that many Ubers in a city with very good public transport and improving active travel options (bike lanes).
- iso947 6y agoI was walking through parliament square yesterday, and was shocked by how few private cars there were. Vans, black cabs, busses made up 80%+ of my limited sample
