Abstract

In recent years, Stated Preference (SP) methods have found increasingly wide application in travel behaviolx analysis, such as estimating the value of time, assessing the likely usage of new services, and valuing aspects of quality of service. However, apart from recent work at ITS, we are not aware of a paper which provides an assessment of the competing ways of designing SP experiments for application in transport research the application and testing of relevant theory is the purpose of this paper. Statistical design is important because it impacts on the accuracy of the results, or the cost of obtaining data, or both. We provide in section 2 an account of statistical design issues relating to fixed choice set discrete choice exercises which are the most common type of SP application in transport research. We discuss how ideas have evolved since the early transport applications and also refer to our recent research which has significant implications for the design of SP choice experiments. Subsequent sections present the results of our tests and our conclusions.
