VISSIM 5.30-05 User Manual

6 The Traffic Network
● Show warnings during import: If this option is active, you have to
confirm every warning on screen. Simultaneously, all messages and
warnings are traced to a Log file and can be listed on screen after the
import.
If this option is not active, no messages will be displayed during import,
but the Log file will be created and the list of messages can be opened
on screen as well subsequently.
● CLOSE closes the window and saves current settings.
● IMPORT starts the import procedure.
● CANCEL closes the window and ignores modified settings.
Instead of ANM Import you may also select the *.ANM file in the Explorer
and open it in the VISSIM window via Drag´n´Drop.
► If no *.INP network file has been loaded, this *.ANM file is imported.
► If an *.INP network file has been loaded which initially was imported via
ANM Import, you may pick to read this file adaptively or initially now.
How the VISSIM Network is built
The ANM Import creates the following VISSIM network elements from
exported VISUM network objects:
VISUM VISSIM
Transport system Vehicle type and vehicle class
Node Node (as segment node,
cf. section 12.3.2)
Link Links (one per segment; e.g. the start of a pocket
creates a new link with one additional lane); multilane
links according to lane geometry, if applicable.
You can create multiple connectors connecting the
same two links and also connectors from or towards
the same lane (those can be exported since VISUM
11.0).
The emergency stop distance for connectors
representing turning movements in nodes is set to
the pocket length minus 10 m.
The front time gap for a conflict of a left-turn and a
parallel crosswalk is set to 2.0 seconds. (This way,
opposite right-turns with a front time gap = 0.5 s
may start prior to the left-turns as soon as their
conflict area has been cleared normally.)
Lane Lanes (with lane-specific permission or closure by
vehicle type)
Turn Connector, with reduced speed area in case of
sufficient curvature.
