ATTITUDE-BEHAVIOR RELATIONSHIPS IN TRAVEL DEMAND MODELLING

摘要: A conceptual dynamic model of the relation between attitudes and travel choice (behaviour) can be developed which distinguishes antecedent variables (characteristics alternatives commuter) process (attitudes perceived availablity constraints). While determine variables, latter are in a complex mutual adjustment mechanism with behaviour. That is, determined by behaviour as function availability constraints. The effect upon studied within framework psychological theory Cognitive Dissonance. asserts that after an individual makes alternatives, he will align his stated to choice, upgrading satisfaction both positive negative attributes chosen alternative downgrading those rejected alternatives. further magnitude these distortions (cognitive dissonance reductions) importance decision making process. Specific hypotheses covering mode toward modes derived from Dissonance Theory. first two refer individuals for whom there no constraints on availabilities alternatives; predict certain relations attitudes, choices actually made. third hypothesis relates through availatility Employing data Ottawa, Canada, have been confirmed. bidirectional attitude-choice causality should used providing transportation planning information. Attitudes, though affected past behaviour, appear indicators potential behavioural change when and/or characteristics change.
