SHORT ABSTACT: Modern mobility systems require detailed representations of travel demand. Activity-based models provide a powerful tool to derive travel demand from daily activity patterns. In this presentation, we propose a novel activity-based modelling approach built on first principles. We assume that a traveller schedules her day in order to maximize her overall utility. To do so, she solves a mixed integer optimization problem which combines discrete decisions, such as whether or not to participate in different activities, and continuous decisions, such as the start times and duration of planned activities. We propose a detailed specification of the optimization problem, illustrate it on concrete examples, and discuss how the model parameters can be calibrated from real-world data.
