6 The Traffic Network
● Check option VISUM Export (Network + link attributes),
● Set intervals (take simulation time interval into consideration)
For VISUM export, option by lane must be unchecked. Attribute LaneNo. is
not exported.
► The Base network file contains VISUM nodes and links with
- link evaluation attributes with constant values during simulation, and
- the user-defined link attribute LinkEvaluation {yes/no}.
► Any Interval network file contains only data coding user-defined link
attributes and their respective values gained in the particular time interval.
Generating VISUM network objects from VISSIM network elements:
► A VISSIM link without segment evaluation is modeled as VISUM link.
► A VISSIM link with segment evaluation is modeled as a set of VISUM
links: from each VISSIM link segment a separate VISUM link is
generated.
Generated VISUM nodes are numbered in adjacent order, starting from 1.
In VISUM, follow the steps outlined below:
► Open the exported base network file first.
► Then read all further export network files *_.NET
additionally. Use the option Read network additively.
The window Read network data additively includes the Conflict
handling column: Select option Overwrite attributes for network object
type LINK.
