Transportation planners need to understand peoples responses in case of introducing new policies. Stated preference (SP) approach examines individual responses to a series of experimentally designed choice alternatives, which are typically described in terms of combinations of attributes with several pre-defmed levels. Besides the ability to directly measure the demand/response under not-yet-existing conditions, the SP approach is able to control statistical problems, to include qualitative factors as explanatory variables, and is cost-efficient to develop models from a relatively small size of samples. This paper first discusses some main methodological issues rela ted to the SP approach and then examines how to represent these issues in the context of policy analysis through several case studies including evaluation of sustainable urban form, prediction of new transit systems, analysis of effects of travel information provision, and assessment of amenity improvement in a neighborhood street. The case study areas cover both developed and developing cities. Finally, the paper argues the importance of using the SP approach as a tool of transportation planning and policy analysis, especially focusing on the uncertainty in the future caused by rapid change in soeio-economic, urban, and transportation environments in developing countries.
