This paper investigates the attitudes of a cross section of residents of a metropolitan area toward 3 automated transportation systems. Respondents to a home interview survey evaluated their satisfaction with each system according to 12 attributes such as travel time, comfort, automatic control, and privacy of the vehicle. Respondents also evaluated their over-all satisfaction for each system and projected their possible use of these systems. In the first phase of the analysis, the interrelations among the respondents' perceptions of the system attributes are examined. Five latent factors are determined through factor analysis to describe the attribute satisfaction ratings: level of service, comfort and privacy, degree of automatic control, out-of-pocket cost, and options and amenities. These factors are consistent for both work and shipping trips. In the second phase, reported overall satisfaction for work and shopping trips is explained in terms of the attributes through the use of linear additive models. Level of service is a significant descriptor of overall satisfaction for work trips; comfort and privacy and options and amenities are added descriptors for shopping travel. The final phase of the analysis uses a nonlinear estimation technique to explain the allocation of work and shopping trips by the respondent. This technique revealed, as did the linear additive model, that satisfaction with a mode is dependent on trip purpose.
