The Evidence Mounts: Uber/Lyft Are Bad for Our Cities

At Streetsblog, Angie Schmitt has compiled a handy list of all the ways in which ride sharing services like Uber and Lyft are having significant negative effects on our cities, the environment, and our health.

Uber and Lyft are just crushing transit service in the U.S. A recent study estimated, for example, they had reduced bus ridership in San Francisco, for example, 12 percent since 2010 โ€” or about 1.7 percent annually. And each year the services are offered, the effect grows, researcher Gregory Erhardt found.

Every person lured from a bus or a train into a Lyft or Uber adds congestion to the streets and emissions to the air. Even in cities that have made tremendous investments in transit โ€” like Seattle which is investing another $50 billion in light rail โ€” Uber and Lyft ridership recently surpassed light rail ridership.

Transit agencies simply cannot complete with private chauffeur service which is subsidized at below real costs by venture capitalists.

Uber and Lyft (and their investors) clearly aren’t going to stop…it’s up to cities and communities to take action. They can’t just let these companies ruin their transit until ride sharing is the only thing left.


Massive data analysis of NYC taxi and Uber data

Todd Schneider used a couple publicly available data sets (NYC taxis, Uber) to explore various aspects of how New Yorkers move about the city. Some of the findings include the rise of Uber:

Let’s add Uber into the mix. I live in Brooklyn, and although I sometimes take taxis, an anecdotal review of my credit card statements suggests that I take about four times as many Ubers as I do taxis. It turns out I’m not alone: between June 2014 and June 2015, the number of Uber pickups in Brooklyn grew by 525%! As of June 2015, the most recent data available when I wrote this, Uber accounts for more than twice as many pickups in Brooklyn compared to yellow taxis, and is rapidly approaching the popularity of green taxis.

…the plausibility of Die Hard III’s taxi ride to stop a subway bombing:

In Die Hard: With a Vengeance, John McClane (Willis) and Zeus Carver (Jackson) have to make it from 72nd and Broadway to the Wall Street 2/3 subway station during morning rush hour in less than 30 minutes, or else a bomb will go off. They commandeer a taxi, drive it frantically through Central Park, tailgate an ambulance, and just barely make it in time (of course the bomb goes off anyway…). Thanks to the TLC’s publicly available data, we can finally address audience concerns about the realism of this sequence.

…where “bridge and tunnel” folks go for fun in Manhattan:

The most popular destinations for B&T trips are in Murray Hill, the Meatpacking District, Chelsea, and Midtown.

Taxi Uber Data

…the privacy implications of releasing taxi data publicly:

For example, I don’t know who owns one of theses beautiful oceanfront homes on East Hampton’s exclusive Further Lane (exact address redacted to protect the innocent). But I do know the exact Brooklyn Heights location and time from which someone (not necessarily the owner) hailed a cab, rode 106.6 miles, and paid a $400 fare with a credit card, including a $110.50 tip.

as well as average travel times to the city’s airports, where investment bankers live, and how many people pay with cash vs. credit cards. Read the whole thing and if you want to play around with the data yourself, Schneider posted all of his scripts and knowhow on Github.

Update: Using summaries published by the New York City Taxi & Limousine Commission, Schneider takes a look at how taxi usage in NYC is shrinking and how usage of Uber is growing.

This graph will continue to update as the TLC releases additional data, but at the time I wrote this in April 2016, the most recent data shows yellow taxis provided 60,000 fewer trips per day in January 2016 compared to one year earlier, while Uber provided 70,000 more trips per day over the same time horizon.

Although the Uber data only begins in 2015, if we zoom out to 2010, it’s even more apparent that yellow taxis are losing market share.

Lyft began reporting data in April 2015, and expanded aggressively throughout that summer, reaching a peak of 19,000 trips per day in December 2015. Over the following 6 weeks, though, Lyft usage tumbled back down to 11,000 trips per day as of January 2016 โ€” a decline of over 40%.
