Abstract: A theory and technique is presented for estimating the business travel market shares of future V/STOL aircraft as functions of the nondemographic mode choice factors of time, cost, safety, comfort, convenience, and weather reliability. A linear mathematical model is described. Inputs to the model are derived directly from questionnaire surveys incorporating semantic differential and multiple choice questions. The technique is demonstrated on a city-pair 112 miles apart where business travel currently favors automobiles. Two V/STOL aircraft types competing with conventional modes in a hypothetical 1985 environment are predicted to attract 48 per cent of the business travel in this city-pair market.
