Abstract
Results are presented from a study of possible order effects in stated-choice experiments tested in the context of transport mode choice decisions. A stated-choice experiment with three alternatives—car, public transport, and bicycle—is used to analyze whether the sequence in which choice sets are presented influences the estimated utility functions of transport modes. The data were collected by means of a self-administered mail questionnaire. More than 950 respondents participated in the experiment. The analyses show that order effects are relatively small but significant. The appearance of the public transport alternative before the bicycle in the choice task influences the utility of public transport significantly. Order effects depend on trip purpose.
