Data Import/Export
● Network Elements
Each network element type can be activated or deactivated for the import.
However, if a network element type is selected, all network element
types that it refers to are automatically selected as well. If a network
element type is deselected, all network element types referring to it are
deselected automatically.
For each network element type of the imported network the numbering
scheme can be specified:
- New Numbers: Each element will get a new number that is higher
than the highest previously existing number of such a network
element (in both networks), by adding a sufficiently high round
number to the old number of the imported network element. (If this
procedure would cause numbers higher than 2 147 483 648, the read
process is canceled with an error message.)
If New Numbers is not checked, each imported network element
keeps its number if this one does not yet exist in the old network, in
which case it is changed as above.
- Keep Duplicates: For each network element without a geometrical
position (e.g. distributions) the user can select if exact duplicates of
existing network elements are to be kept (with new numbers) or not.
Example: If the vehicle types 1..6 are defined identically in both
networks then Keep duplicates changes the numbers of the vehicle
types of the imported network to 11..16 (usually this is not desirable).
If Keep Duplicates is not checked, the corresponding network
elements of both the existing and the imported files are compared by
all their properties except for numbers. If two network elements are
identical (no matter what number they have) then all references from
the imported network are changed to that network element of the
existing file.
6.2.1.2 SYNCHRO 7 Import (add-on module)
VISSIM supports the import of entire networks, including signals and signal
timing, from the software package SYNCHRO, version 7, if this module is
part of your VISSIM license. The SYNCHRO network must be saved as a
*.CSV combined data file prior to data import in VISSIM.
This functionality does not facilitate the import of data generated with an
elder SYNCHRO version.
VISSIM will import all elements from the SYNCHRO 7 file, including network
geometry, volumes, turning movements, vehicle compositions, intersection
control, and signal timing. All signal timing will be imported to individual Ring
Barrier Control (RBC) files for VISSIM.
To use this feature, click menu FILE – IMPORT… - SYNCHRO 7.
The SYNCHRO 7 Import window opens.
