Uber and Lyft are still crushing transit across the U.S, according to new study examining the effects in 22 cities.
When Uber and Lyft enter a city, the app-based taxis decrease rail ridership by 1.29 percent per year and decrease bus ridership by 1.7 percent, the study by three University of Kentucky researchers found [PDF].
Worse, the effect is cumulative. Authors Michael Graehler, Richard Mucci and Gregory Erhardt estimate that Uber and Lyft for example, have reduced bus ridership in San Francisco a staggering 12.7 percent since they entered the market in 2010.
This isn’t the first study to make such findings, but it is one of the broadest, helping to explain why transit ridership has declined in almost every U.S. city over recent years. These declines could not be explained by service reductions or by maintenance issues — although those have been an issue in Washington and New York City.
