Transportation Network Companies (TNCs) are changing the transportation ecosystem, but micro-decisions of travelers and TNC drivers need to be better understood to assess their system-level impacts. Using a unique sample (N = 11,902) of the U.S. population residing in TNC-served areas, we estimate preferences of TNC travelers for a) being a rider, a driver, or a non-user of TNC services; and b) to use pooled ridesourcing. In addition, using a large sample of TNC drivers, we estimate their inclination to a) switch to vehicles with better fuel economy; and b) buy, rent or lease a new vehicle with driving for TNCs being a major contributing factor. The population-weighted statistical analysis indicates that TNCs are mainly attracting personal vehicle users as riders, without substantially affecting demand for transit.
