Merging networks

With this functionality you can compare two networks and display the differences (Fundamentals: Network merge).

In the two networks to be compared, the following must correspond with each other:

  • The calendar settings (calendar type and time interval)
  • All modes, transport systems, demand segments (code) and the allocations between these objects (for example demand segment to mode)
  • The types of transport systems (PrT, PuT etc.).
  • The vehicle journey items
  • If there are network objects in network 1 and network 2 with an identical ID, all objects to which they refer must also have the same ID. Deviant surface objects are an exception (main nodes, zones, main zones, territories, POIs) as are deviant transport systems of a line. Here, Visum uses the reference from network 1.

Notes: Main nodes can only be compared if they consist of identical partial nodes in both networks.

Otherwise a warning is issued and the opening of the merged network is cancelled.
