Similarly to the EVA trip generation method in the EVA model for passenger demand (Calculating EVA trip generation), the Tour-based model - Trip generation method calculates the number of home trips by demand stratum for each zone (Fundamentals: Tour-based model - Trip generation).
1. On the toolbar, click the 
Open 'Procedure sequence' window button.
The Procedure sequence window opens.
2. To the procedure sequence, at the position of your choice, add the procedure Tour-based model - Trip generation of the Demand model category (Setting up and starting the procedure sequence).
3. In the row of the added procedure, click the button in the Reference object(s) column.
The Demand strata selection Tour-based model window opens.
4. In the Select demand model list, click the demand model the demand strata belong to.
5. In the Demand strata selection list, select the demand strata you would like to calculate the Tour-based model - Trip generation for.
|
Tips: To select multiple demand strata, hold down the Ctrl key while clicking the desired entries one by one. Alternatively, you may pre-select corresponding demand strata for certain person groups and activity pairs. Therefore, select the desired demand objects in the Person groups and Activity pairs selection lists and click the Accept pre-selection button. |
6. Confirm with OK.
The demand strata selected are listed in the Reference object(s) column.
7. Make sure the added procedure is highlighted. Then, in the Operations section, click the Edit button.
The Parameters: Tour-based model - Trip generation window opens.
8. Make the desired changes.

For active zones only |
If this option has been checked, Tour-based model - Trip generation is calculated only for active zones (Using filters to set network objects active or passive and Setting network objects active/passive via the spatial selection). |

Sum up values |
If this option has been checked, the output attribute values are added to the given values. |

Mobility rate constant |
|
|
Mobility rate |
If you select the Mobility rate constant option for a person group, you can enter a value ≥ 0 for the specific demand of this group. |
|
SA factor home constant |
Note SA = study area |
|
SA factor home |
If you select the SA factor home constant option for a person group, you can enter a value ≥ 0 as mobility rate for the specific home demand. |
If this option has been checked, the mobility rate of the person group is constant for the demand stratum, i.e. it is the same for all zones.
If the option is not selected, a specific value (from zone attribute) is considered for each zone 9. Confirm with OK.
10. Execute the procedure (Executing procedures in the procedure sequence).
Tour-based model - trip generation is calculated. The calculation results are saved per demand stratum to the zone attribute Home trips (Editing the demand of tour-based demand strata).
|
Tip: You can display the results in zone lists (Viewing the demand of Tour-based model demand strata in lists) or in the network graphics (Displaying data graphically and in lists). |
