5. Click OK to start the data export.
For the VISUM version file *.VER you can enter folder and filename.
Additionally to the *.VER file, the export routine will create a VISUM
network file *.NET and multiple VISUM route files *.RIM.
From the total demand in VISSIM matrices, a VISUM matrix file *.MTX is
generated for export. Only the demand in the export time interval
(simulation start time + simulation period as defined by the user in the
Simulation parameters window) is regarded for export. If a VISSIM matrix
file is not completely in the export time interval, then only the portion in the
export time interval will be exported. Please note: The demand is summed
up, thus you will not receive separate matrices for different VISSIM vehicle
types and/or vehicle classes.
Route import files are only exported if VISSIM cost and path files are
available. Route import files contain the routes and volumes resulting from
the Dynamic assignment: For each Dynamic assignment evaluation interval
a separate *.RIM file is generated.
If cost and path files do not exist, a warning will appear and only the
network and matrix data will be exported.
Closures of edges or connectors are exported to VISUM and can be
regarded during the assignment. Normally, VISUM does not use paths
which are not possible in VISSIM.
The only exception to this rule are disjunctive parallel edges between two
VISSIM nodes that either originate from different turns or lead to different
turns. These are exported as a consolidated edge to VISUM. This might
lead to paths determined in a VISUM assignment which cannot be applied
in VISSIM.
For details on Route import in VISUM please refer to chapter “Program
Interfaces” in the VISUM User Manual.

How to open a version file *.VER in VISUM
1. Click FILE – OPEN VERSION.
2. In the Open version file window, select the desired version file *.VER.
The VISUM version file created during export contains all required data.
There is no need to open the additionally created VISUM files separately. If
no version file was created during export, you may open the additionally
created files instead one by one.
