ABSTRACT
The major theme of the workshop was the relationship between attitudes towards issues and behaviour. The workshop identified a number of decision or choice processes, some of which are well-known in the psychological literature but perhaps less well-known in transport research. Thus, the workshop recommended that research priority be given to dynamic and interactive effects and that the utility of simultaneous-equation methods and learning models be investigated. A major portion of the discussion focused upon the theoretical role of psychological theory and measurement procedures as it relates to existing theory and practice in travel-demand modelling. The main issues highlighted were the relationships between physical or engineering measures and self-reports or psychological values, and the relationship of these psychological values to choice. Plan Evaluation and Impact Assessment can be approached through decision studies in which the public or subgroups thereof evaluate the alternatives.
