Urban Planning Professor David King has found that rather than working in competition, taxi cabs actually augment public transit networks.
When comparing taxi trips from the morning and evening, King finds a geographical asymmetry indicating that commuters are using taxis for just one leg of their daily commute, and in this case it is usually the morning.
King has spent a lot of time advocating his synergistic theory and thinking about the subject. Alongside colleagues Matthew Daus and Jonathan Peters of CUNY, he presented a paper on the complimentary nature of cabs at a meeting of the Transportation Research Board. In it, they argue that "taxi service is a critical aspect of the transit system."
