A preliminary consideration of the process leading to acts of choice is outlined in terms of the underlying dynamic process that molds the consumer's preference functions. This is designed with 3 main objectives in mind: the role of attitudes in influencing behavior, the directional relation between behavior and attitudes, and the identification of various homogeneous groups of travelers based on various prespecified physical and value-associated criteria and designed to ensure a more meaningful aggregation where within-group variance is minimized and between-group variance is maximized. An important feature of attitude-behavior models is that, being based on psychological principles, they are applicable to more than simply transportation problems. They can, therefore, be applied in some form to all aspects of human behavior (though perhaps with varying success) and so provide a basis for more coordination in governmental decision-making. A consideration of data requrements can emphatically contribute to a greater understanding of the causal connection within and between various acts of travel choice and accordingly lead to improvements in the models themselves via improved perspective in the selection of variables.
