Visum provides several assignment procedures for the PrT. There are static assignment procedures without explicit time modeling as well as procedures which use a time dynamic traffic flow model (Fundamentals: User model PrT).
Any desired assignment procedure you may integrate in the user-defined procedure sequence. For each procedure, specific parameters have to be set. Additionally, general settings are regarded by various procedures.

Note: If your network contains assignment results, you may delete them either directly or within the procedure sequence, e.g. as the procedure which is directly followed by the new assignment calculation (Deleting PrT/PuT assignment results). |
