Both macroscopic and activity-based demand models have their advantages and disadvantages. The main advantages of the procedures available at Visum over macroscopic models lie in aspects such as
-
Time-differentiated skims
-
High spatial resolution
-
Consistent tour context
-
Multimodal trip chains
-
Explicit choice of workplace
-
Individual user preferences instead of behavioral homogeneous person groups
This allows many of the current challenges to be analyzed much more precisely than with conventional aggregated models, for example:
-
Morning toll (spatial/dynamic/adaptive pricing systems)
-
Parking space management
-
E-mobility
-
Work from home
-
Constant workplace for short-term forecasts
At the same time, activity-based models have some disadvantages, such as
-
Moderately increased budgets for time and effort
-
Slightly higher data requirements (finer resolution)
-
Longer run times
However, a decision for or against activity-based models should be based on the requirements of the model.
