THE USE OF CONJOINT ANALYSIS IN TRANSPORT RESEARCH

Conjoint analysis is a technique developed through the course of the 1970s for use in market research. It is a technique in which respondents are asked to state their preferences for alternatives which offer various combinations of system attributes. The scope of conjoint analysis as a means of understanding the importance of specific aspects of a transport product is considerable. Following a brief review of the development of the technique over the last 10 years, the authors describe two research applications for which they have been responsible. In the first, conjoint analysis was used to identify demand elasticities with respect to service frequency, and as a by-product of the main research programme, to estimate values of time. In the second project, conjoint analysis was used to establish passenger preferences for some detailed aspects of vehicle design in respect of seating layouts, smoking restrictions and so forth. For each case the type of statistical design deployed is described and what are seen as essential features of the conjoint technique are identified. Comparisons are made with some research which has certain similarities which has been conducted by SNCF in France. Based on the general principles enunciated, a description is given of the scope and limitations of the technique in the transport research and planning fields. (Author/TRRL)
