The Taxi Subcommittee sponsors research on the role of taxis as paratransit providers. This includes use of taxis in user-side subsidy programs serving those with specialized transportation needs, for non-dedicated and dedicated ADA paratransit services, as supplemental same-day taxi programs for ADA paratransit, and wheelchair accessible taxis for subsidized and non-subsidized services. The subcommittee is expected to act as a liaison with related TRB committees that deal with taxis and with the broader research community involved with taxi transportation.
