Modeling the contribution of multi-tasking to the utility of travel episodes is a critical objective in the development of the next generation of activity-based models. Conducting activities whilst travelling may affect the utility of activity episodes in a daily schedule. If evidence to that effect can be established, a reformulation of current activity-based models is required. In this paper, as a first step towards the development of such comprehensive activity-based models, the authors formulate a random effects regression model to analyze the effects of multi-tasking on respondents’ judgments of travel experiences of distinct travel episodes. The authors extend previous research with a focus on the extent and nature of multi-tasking during a single trip. The authors analyze repeated judgments of the same individuals for multiple travel episodes, collected over a period of three consecutive months. This longitudinal data analysis allows the authors to better differentiate between personality traits, temporal effects, multi-tasking and the embedding of travel episodes in the larger activity-travel chains. Results indicate that multi-tasking has a positive impact on travelers’ judgments of travel experiences. Significant effects were also found for the kind of activity that was conducted immediately before and after the travel episode. The authors conclude therefore that multi-tasking should be systematically incorporated into a new generation of activity-based models, and that the suggested conceptualization and model formulation is a feasible and valuable building block in the development of such more comprehensive activity-based models.
