Role of stated preference methods in planning for sustainable urban transportation: State of practice and future prospects

Abstract

This paper adopts the World Bank's 1996 definition of sustainable transportation and attempts to identify ways of improving the urban transportation planning process and methodology. After a literature review of related studies conducted in different parts of the world over the past decade or so, the major theoretical and methodological advances in stated preference (SP) surveys are summarized. Then, the paper continues to suggest ways of how SP techniques can be used side-by-side with the traditional four-stage transportation planning model. Lastly, it concludes with some future directions of change if these useful techniques are to play a more important role in planning for sustainable urban transportation.
