ATTITUDINAL MEASURES IN MODELS OF CHOICE

A complete specification of a choice model should include all factors that are relevant to that choice process, including qualitative aspects of the transport system characteristics. In the present state of knowledge an appropriate method of including these is by attitudinal measures of the characteristics. The inclusion of attitudinal variables in mode choice models has been shown to considerably improve both the performance of the model, and the estimates of value of time that can be obtained from it. The ability of individuals to respond consistently to attitude questions is examined, with evidence supporting the usefulness of attitude measures in a planning context. The problem of bias in reported attitude with its implications for the measurement of perceived levels of system variables is treated. The application of attitude measures to choice models is only one area in which these techniques can be of use. Evidence is reported to suggest that only in special and rather rare circumstances are choice processes compensatory (ie, involve a trade off). Attitudinal research has already achieved considerable success in isolating the likely effects and impacts of policy changes, and is shown to have great potential for further advances. /TRRL/
