As shown in this scatter graph, ride-hail and public transit usage are highly correlated. Cities like San Francisco, Washington DC and Boston, with high per-capita TNC ridership, also have a high percentage of transit commuters. This is not surprising since both TNCs and transit draw primarily from the pool of people who are getting around by means other than personally-owned motor vehicles.
In some ways TNCs and transit can be complementary, as when someone takes the train to work in the morning and a ride-hail home late the same night. They are also clearly competitive; surveys show that around 40 percent of ride-hail trips would have been made by public transit if TNCs were not available.
