Evaluating the Impact of Lyft App Integration on the Public Bike Share Programs in Four Major U.S. Cities Using Synthetic Control

This project applies synthetic control to show that (1) Lyft mobile app integration in June 2019 caused an uplift in monthly casual trip rate and monthly casual trips in public bike share programs in Chicago, Boston, and New York City from June to December 2019, (2) the interventions did not led to increase in monthly total trips and monthly membership trips in these programs during the same time period. It suggests that the increase in monthly casual trips in the three cities are likely drawn from previously membership riders, rather than from new first-time public bike riders.
