A stated-preference experiment was performed in Calgary to examine the nature of various influences on the decision to carpool to work in the central business district. A total of 678 complete interviews were conducted. In each interview, the respondent was presented with five successive pairs of possible automobile use alternatives and asked to indicate which alternative was preferred in each case. This forced the respondent to trade off among conditions regarding specific attributes. Several socioeconomic characteristics of the respondent and attributes of the respondent's actual trip to work were also recorded, and the contents of the hypothetical alternatives presented were adjusted accordingly. The observations thus obtained were used to estimate the parameter values for different utility functions in logit models representing this choice of behavior. The results indicate, among other things, that the extra time spent in the automobile serving other carpool participants is valued at a premium rate of about $4.00 (Canadian) per hour (or about 45 percent) more than the automobile ride time for the direct trip; the availability of a guaranteed ride home has a value roughly equivalent to the basic transit fare in Calgary; and each additional household member in a carpool adds further benefit in a reasonably linear manner but does not alter the effect of parking costs for the respondent, whereas each additional non-household member does not add further benefit but does tend to reduce in a nonlinear manner the effect of parking costs for the respondent.
