Managing objects of activity-based models

The demand module ABM enables the creation of a microscopic demand model based on individual decisions of individual persons. PTV Visum offers the corresponding data structures (persons, activity executions, tours, ...) and possibilities of visualization (Fundamentals: Activity-based model (ABM)). The model core, which contains the decision models, is programmed by the user in a script.

You insert objects of the activity-based model (ABM) into lists via menu Demand > ABM. Due to the dependencies, you must adhere to a certain sequence when inserting the objects.

Insert the objects in the following order:

  • Activities
  • Locations
  • Activity locations
  • Households
  • Persons
  • Schedules
  • Activity executions
  • Tours
  • Trips

Tip: You can also access the objects via the Lists > Demand menu.

In the corresponding Lists, you can insert, edit, and delete objects.

Markings of ABM objects are passed on to linked objects of the ABM data model when synchronization is activated. For example, the schedules linked to a selected person are also marked in the corresponding list.

Note: You can display activities at zones, POIs, or locations in the profile view (Displaying profiles).
