The saved paths are not changed, but this is what flow bundles are using. If you want to compare flow bundle volumes with link volumes, there are three methods.

Why are the assignment results between two Visum versions not identical The calculation algorithms the procedures are based on are improved in new Visum versions. There are additional options integrated and new research results implementated. For this reason, the assignment results may differ. Permalink. VIS1. Why can Pr. T assignment results be different, with and without main nodes If a model contains main nodes, the links, nodes and turns within the main nodes are no longer considered. Therefore the model is different and the paths differ too the path is searched from cordon link to cordon link of a main node, using a main turn. A part of the path links and turns within the main node is omitted. VIS1. 02. 89Why are connectors by shares not met after an assignment Pr. T The Connectors shares can be disabled with the setting. Calculate General procedure settings Pr. T settings Connector weights apply to Total trips MPA off. When using Each single OD pair instead, the connectors shares are considered. You can distribute the demand among a zones Pr. T connectors A absolutely freely or B proportionally by shares. A If a zone has multiple connectors and the zone is set to Absolute, this will use the connectors according to shortest paths. It can be that a connector does not get any volume at all. B To meet connector shares, use the zone setting By shares. In this case choose between Total trips MPA off or Each single OD pair. Total trips MPA off is a volume dependent consideration, the connectors capacities are taken according to the shares and the impedance of connectors is calculated by a VDF. This way, you usually wont reach exact shares, which does however depend on how hard the VDF is set. Each single OD pair is in fact a multi point assignment MPA, the demand of zones with proportional demand distribution is divided appropriate to these shares thus the demand matrix is expanded and disaggregated before the assignment. After the assignment, the matrix is aggregated again. This way, the connectors will meet exactly their shares. But caution, this takes extra calculation time and memory capacity. PTVAssignmentPr.

The toll is defined in combination with the TRIBUT Equilibrium assignment for every single link with the link attribute toll Pr. TSys. barely suitable for TRIBUT EquilibriumLohse. Example German truck toll on national highways. Area toll which is applied for a special area object. Example London. 3 Matrix toll, to model degressive road pricing schemes. Example french highways. The second and the third one are administrated as toll system and only work in combination with TRIBUT EquilibriumLohse. The consideration of toll systems in the TRIBUT Equilibrium assignment were subordinated, because the implementation investment and the expected calculation time are not expected to result in anything comparable to TRIBUT EquilibriumLohse. A vignette toll, which in contrary to area toll allows re entry on particular link types or does not constrain a particular zone with extra costs, is currently not possible in Visum.

VIS9. 26. 8With an active blocking back calculation less traffic arrives than without blocking back calculation. The reason lies within the somewhat contradictory combination of a static assignment and the dynamic procedure blocking back Dynamic assignments do not take blocking back into account, DUE uses an own procedure. The traffic load on links with a capacity bottleneck and ensuing links is smaller, because only the traffic that got through these links during the blocking back 1st phase is counted. Capacity and a static assignment should share the same time scope, typically a day, or an hour. Therefore traffic not able to get along capacity reduced links will reach its destination, but beyond this time scope. The links before the capacity bottleneck get a mixed traffic volume, counting the traffic that got through the traffic stocked on these links. The stocking capacity is defined in a link attribute Edit link Congestion Stocking Capacity. Traffic exceeding this stocking capacity is blocked back onto the preceding link or links. The Pr. T paths list shows, that all traffic was loaded onto the paths, thus left the origin but not necessarily reached its destination.
