ABSTRACT
The workshop was charged with exploring the justifications for pursuing improved approaches to travel modelling by addressing the following questions. Indeed, one of the principal topics of the workshop's discussion was to compare the roles of prediction procedures which apply disaggregate travel models in a disaggregate manner with more commonly used procedures. The workshop's discussions concentrated on disaggregate travel modelling procedures such as those developed and applied by Charles River Associates for the Environmental Protection Agency, and by Cambridge Systematics, Inc., for the Federal Energy Administration. The 'behavioural' logic of disaggregate travel models, to the extent that it allows an improved understanding of the causes of individual travel behaviour, enhances the modeller's ability to assist in this process of generating policy options. Perhaps the greatest appeal of the SRGP disaggregate modelling approach is the flexibility it offers for summarising output evaluation measures.
