VISSIM 5.30-05 User Manual

11 Evaluation Types for Simulations of Vehicles
11.11 Link Evaluation
The link evaluation feature allows the user to gather simulation results based
on an area of an active link rather than based on individual vehicles.
Data is collected about vehicles that pass over that lane segment for a userdefined
time interval.
The segment length can be specified
► separately for each active link or connector or
► in Multiselect mode for all active links/connectors.
The Link Evaluation window also allows for VISUM Export of VISSIM
network data, cf. section 6.2.2.2.
Definition
For all links and connectors to be included in the link evaluation,
► the property Link Evaluation needs to be active and
► the Segment length needs to be defined (cf. sections 6.3.1 and 6.3.2).
In order to set these properties for multiple links/connectors at the same time
the Multiselect mode can be used (cf. section 3.3.2 for details).
Configuration
In order to get the desired output data additional information is needed. This
is to be provided within the Link Evaluation Configuration window that is
accessible by pressing the CONFIGURATION button in EVALUATION – FILES… -
[VEHICLES], once the option Link Evaluations is ticked. The window allows for
definition of any combination of parameters.
If Database output is not active each layout line results in a column within the
output file *.STR.
The configuration settings will be saved to an external file (*:SAK).
