Output parameters

In the TRE GUI, in the Output tab, you can set all parameters associated to output and result configurations.

Parameter Type Validity Description

AlwaysExportBinaryResults

Boolean

{true,false}

Export the binary results for the viewer.If the TRE viewer is not needed, this process can be skipped to save time.

  • true = Export always.
  • false = Export only if running as Visum Addin or BKGM = 0.

Default is true

AssignmentPathThreshold

Real

(0,1]

For every pair Origin-Destination (OD routes), are exported (into .rim file) only flows associated to a specifc ratio of the demand => AssignmentPathThreshold.

The demand of the "removed OD routes", where the ratio of the demand < AssignmentPathThreshold, is proportionally distribuited on the remaining paths.

It is guaranteed at least one route per OD (with positive demand).

Default value: 0.01.

ClearOldResultsOnInit

Boolean

{true,false}

Handles data tables.

  • true: Clear results tables at simulation initialization time; if RESI>0, the daily and history tables are renamed, and empty ones are created with the original name.
  • false: Otherwise.

Default is true.

DestinationTPRB

Boolean

{true,false}

Exports to DB the turn probabilities.

  • true = Exports always. If AssignmentAlgorithm = temporal layer DTA, are exported TPRB per destination. Otherwise, TPRB are exported according with DS_TPRB_OUT (see → List of datasources).
  • false = TPRB are exported according with DS_TPRB_OUT.

Default is false.

ExportAssignmentPaths

Boolean

{true,false}

Export the assignment OD paths.

Default is false.

ExportIntermediate
IterationResults
BinStep

Int32

≥ 0

Number of DTA equilibrium iterations after which the results are exported.

This can be used to gain periodical insights into the equilibrium convergence state.

Special values:

  • 0 = exports results only at the end of the equilibrium

Default is 0.

JunctionResults

Boolean

{true,false}

Exports junction results such as lane and lane turn result output.

  • true = Exports always.
  • false = Otherwise.

Default is true.

KeepBinAndResFiles

Boolean

{true,false}

Handles the override of previous result binary files.

true: Avoids the overriding of old binary result files and allows to store the sequence of results produced. Stored results can be used for post-process analysis of a series of simulations.

false: Otherwise.

Default is false.

NormalizeDistortedResults

Boolean

{true,false}

Normalizes results if arc characteristics have been altered.

  • true: In case of modification of arc characteristics (for example, StretchArcs=true (see → StretchArcs)), enables the back-normalization of the results according to the original values.

    Important:  Not all results can be back-normalized.

  • false: Otherwise.

Default is true.

For details about the normalization of results, → TRE (support issues) > Travel Time and Simulation Time: effects of the NormalizeDistortedResults parameter

RESI

Int32

≥ −1

Number of past days to be kept.

This option affects:

Upon day change, the tables are backed up by appending a suffix indicating how many days in the past they refer to.

For example, if RESI = 2:

  • RLIN_TSYS_TRE is backed up to RLIN_TSYS_TRE_1
  • RLIN_TSYS_TRE_1 is backed up to RLIN_TSYS_TRE_2
  • The previous version of RLIN_TSYS_TRE_2 is deleted

Special values:

  • 0 = Do not back up.
  • −1 = Write the results of all days to a unique table.

Default is 0.

ResIntD

Double

≥ 0.001

Defines the duration, measured in seconds [s], of result intervals for the supply simulation.

Results over such intervals are the aggregation of the results computed during each simulation time interval (see → SimIntD).

Default is 3600.

ResultClasses

Int32

{0,1,2}

Defines the aggregation of the TRE results in case of multimodal simulation.

  • 0 = Results per mode.
  • 1 = Results per transport system (TSYS).
  • 2 = Results per demand segment (TSYS).

Default is 1.

SmoothSpikes

Int32

{0,1,2}

In travel time computation, determines the smoothing of spikes that were due to numerical errors affecting the travel time computation procedure.

  • 0 = No smoothing.
  • 1 = Smooth only ascending and descending inflections.
  • 2 = Smooth all inflections (also descending and then ascending).

Default is 1.

StoreDailyResults

Boolean

{true,false}

Handles daily results.

  • true: Enables the storage of the real-time results (_RLTM) in the daily table (_FORE).
  • false: Otherwise.

Default is true.

StoreHistoryResults

Boolean

{true,false}

Handles history results.

  • true: Enables the storage of the real-time results (_RLTM) in the history table (_TRE).
  • false: Otherwise.

Default is true.

StoreRltmResults

Boolean

{true,false}

Handles simulation results.

  • true: Enables the export of the simulation results in the last simulation results table (_RLTM).
  • false: Otherwise.

Default is true.

TRES

Int32

{0,1,2}

Turn / main turn result output.

  • 0 = No turn output.
  • 1 = Only turns defined in the input (meaningful only in the case of the DB network input).
  • 2 = All permitted turns.

Default is 2.

WriteConnectorResultsInDB

Boolean

{true,false}

Handles link results.

  • true: TRE exports in the _RLTM table also link results for connector links.
  • false: Otherwise.

Default is false.

WriteOnlyClocInHistory

Boolean

{true,false}

Handles link results associated with count locations.

  • true: TRE exports in the RLIN_SYS_TRE table results of links with count locations only. It is generally used when you are interested in forecast analysis (only on monitored links).
  • false: Otherwise.

Default is false.

WriteOnlyClocInRltm

Boolean

{true,false}

Handles link results associated with count locations.

  • true: TRE exports in the RTLM table results of links with count locations only. It is generally used when you are interested in forecast analysis (only on monitored links).
  • false: Otherwise.

Default is false.

WriteOnlyEquivalent
ResultsInDB

Boolean

{true,false}

Handles only link results for the equivalent flow.

  • true: Exports to the _RLTM table only link results for the equivalent flow.
  • false: Otherwise.

Default is true.

UseVisumAsViewer

Boolean

{true,false}

Determines the result viewer.

Default is false.
