This paper argues that certain choice problems in transportation research can be best conceptualized as problems of portfolio choice. It discusses how portfolio choice problems can be studied using discrete choice experiments, stated choice (conjoint) methods. Issues in the construction in the design of experiments, model specification and estimation are discussed. A working example illustrates the basic approach. Finally, possible extensions of the basic approach are identified.
