ALTERNATIVE MODELLING PROCEDURES IN STUDIES OF TRAVEL MODE CHOICE: A REVIEW AND APPRAISAL

A question often asked of modellers is "does it really make a difference to the final result whether you use technique A or B or C?" a common response is "I think so but I have not made the comparisons; however it can be argued on theoretical grounds that technique b is likely to be superior." This paper documents the theoretical merits of seven econometric model forms and explores the empirical differences among them using a well-specified set of explanatory variables associated with the mode-choice decision for a cross-section of Sydney commuters. The empirical results suggest that the standard goodness-of-fit criteria (t-values, prediction success and elasticities) provide an inadequate basis for selecting a modelling procedure from a set of non-nested models which are estimated using different statistical methods (i.e. Ols and mle). Simplified models are also a dangerous mechanism for screening explanatory variables for inclusion/exclusion in more appropriate models. There is a need for research to establish other criteria and tests for selection of a model form. (Author/TRRL)
