CONDITIONS FOR SUCCESSFUL MEASUREMENT IN TIME VALUATION STUDIES

This paper arose out of the feeling that in the last few years progress in getting usable values of time has not matched progress in theoretical understanding. It is argued that better theoretical insight has coincided with less attention to the conditions predisposing to successful measurement; the quality of data and the experimental situations have been relatively neglected. The argument is developed for a binary choice situation for the sake of convenience and because most studies have taken this form. A subtheme of the paper is that to be efficient in predicting modal choice is not necessarily to be efficient in deriving values of time. After establishing the importance, in principle, of observing the conditions for a "good" study opportunity, the paper then considers how far recent British studies have fulfilled these conditions. Because they appear to have considerable shortcomings, the conclusion is drawn that there are as yet insufficient grounds to reject earlier notions about values of time.
