Abstract: Citizens' preferences concerning bus transportation in Boulder, Colorado, were ascertained by two different but related techniques. The primary method was through a computerized game (’CARTFED,’ or Computer-Aided-Real-Time-Feedback Decision) in which subjects are asked to design a desirable bus system by choosing values for system characteristics. Subject's enter these in a portable computer-terminal and the computer calculates and reports the associated deficit, whereupon subjects reiterate making trade-offs to reduce the deficit to an acceptable level. In order to program the computer to calculate the deficits associated with, a wide variety of systems, it was necessary to estimate cost and revenue functions. Since the latter depends upon demand, a prerequisite to the CARTFED program-was the estimation of citizens' preferences by a different technique, which took the form of a questionnaire survey in which respondents were presented with randomly-generated profiles of possible bus systems and asked how often they would use such a system. Multiple regression analysis of the responses yielded the demand function necessary for the CARTFED program. This paper describes both techniques and their results.
