The use of choice heuristic in daily activity travel behaviour: an expert system

Abstract

This research project aims at identifying the critical spatial factors in an individual’s mental map which influence daily activity travel behaviour in order to improve the agentbased modelling of activity travel behaviour by means of a computational process model. A qualitative travel survey and in depth interviews are used to identify the spatial factors that appear in the destination and travel mode choice heuristics of experts when discussing their daily activity space. Recorded interviews are processed through ATLAS.ti. First, the representative IF-THEN heuristics used by the experts are identified and framed within the daily activity travel decision process and classified in a script network view. In addition the occurring spatial elements are indicated.
