In the DStrata tab, you can edit the value of the productions and attractions calculated for the specific zone.
The productions and attractions of the demand strata are calculated for each zone in the (EVA) trip generation step of the demand calculation (Starting the iterative repetition).
For demand models of type EVA-P (Managing demand objects), you can edit the value of further demand volumes.

Description |
|
Select demand model |
Use the drop-down list to select the demand model, the demand strata of which you want to display in the list (Managing demand objects). |
|
DStratum |
Demand strata defined for the selected demand model (Managing demand objects). |
|
Productions |
Number of trips that start at the zone |
|
Attractions |
Number of trips that terminate at the zone |
|
Home trips |
Number of trips that originate and terminate at the respective zone Note This column is only available for demand models of type EVA-P and Tour-based model. |
|
Production target |
Number of trips that start at the respective zone, which is calculated in the EVA trip generation step before taking account of the constraints (Modeling demand). Note This column is only available for demand models of type EVA-P. |
|
Attractions target |
Number of trips that terminate at the respective zone, which is calculated in the EVA trip generation step before taking account of the constraints (Modeling demand). Note This column is only available for demand models of type EVA-P. |
|
Balance factor productions |
Factor which is calculated optionally when solving the trilinear equation system during EVA distribution/mode choice for the production side (Fundamentals: EVA trip distribution and mode choice). |
|
Balance factor attractions |
Factor which is calculated optionally when solving the trilinear equation system during EVA distribution/mode choice for the attraction side (Fundamentals: EVA trip distribution and mode choice). |
|
You can also edit the values via menu Demand > Demand models > tab Demand strata > button Productions/attractions (Managing demand objects). |
