The research in this paper develops and estimates aggregate models of intercity passenger mode choice. In contrast to standard models of intercity travel demands which assume that no traveler is captive to any mode, the primary focus of this paper is the extent to which travel time and cost elasticities change if some travelers are captive to a given mode. A secondary focus of the paper considers the effect that past changes in common carrier market structures have had on intercity modal shares. Based upon aggregate time series data from 1960 - 1991, the results indicate that intercity modal demands are sensitive to underlying assumptions about traveler captivity. Further, relative to automobile travel, changes in the air, rail, and bus market structures have decreased the demand for these modes, all else held constant.
