If this option has been selected, the activity is defined as home location of traveling persons. Note You can select only one activity as home activity. |

Structural properties |
This button opens a separate window for the respective activity. Here you can select the production or attraction potential properties for trip generation (Fundamentals: EVA data model). |

If this option has been selected, the activity is defined as home location of traveling persons. Note You can select only one activity as home activity. |
|
Rank |
In an activity chain, the activity with the lowest numerical value is regarded as the main activity; in the case of a tie, the first is regarded as the main activity. Rank is considered when you use the Rubberbanding functionality to calculate trip distribution (Fundamentals: Using the rubber banding function for trip distribution) Note We recommend to clearly define the main activity and to avoid multiple activities with the same lowest value. |
|
Structural property |
This button opens a separate window for the respective activity. Here you can select the attraction potential properties for trip distribution (Fundamentals: Tour-based model). |
|
Double constraint |
If this option has been selected, Tour-based model - Trip distribution will consider the double constraint for the particular activity (Fundamentals: Tour-based model). Note For the home activity, double constraint is always regarded. |
|
Joint coupling of demand strata |
If the option is selected, in the trip distribution of the tour-based model, the target potential is divided between all demand strata of the activity (Fundamentals: Tour-based model). Note This option is provided only if the option Double constraint has been selected. |
|
CF DMin |
Factor for the lower limit of the attraction (Fundamentals: Tour-based model) Notes This option is only provided if option Double constraint has been selected for this activity. For the home activity, the factor is always 1.0. |
|
CF DMax |
Factor for the upper limit of the attraction (Fundamentals: Tour-based model) Notes This option is only provided if option Double constraint has been selected for this activity. For the home activity, the factor is always 1.0. |
|
Note: The factors CF DMin and CF DMax define a constraint for the destination side. For the origin side, the constraint is always hard. Then the (origin and destination bound) distribution is calculated for each activity pair according to the constraint factors chosen for the destination side (Fundamentals: Tour-based model: trip distribution / mode choice combined). |
