Both macroscopic and activity-based demand models have their advantages and disadvantages. Compared to macroscopic demand models, the main advantages of activity-based models lie in aspects such as
- individual user preferences instead of behavioral homogeneous person groups
- continuous time dimension instead of 24-hour models
- high spatial resolution instead of zones
- individual model specification instead of fixed model structures
On the other hand, activity-based models have some disadvantages, such as
- They require higher budgets for time and effort.
- They do not achieve comparatively stable results like macro models.
- They have longer run times than macroscopic demand models.
However, a decision for or against activity-based models should be based on the requirements of the model.
