Properties and options of activities

Demand models of the EVA-P type

Element

Description

Code

Short name of the activity

Name

Long name of the activity

Home

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).

Demand models of the tour-based model type

Element

Description

Code

Short name of the activity

Name

Long name of the activity

Home

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).

Demand models of the type ABM

Element

Description

Code

If this option has been selected, the activity is defined as home location of traveling persons.

Note

For models of type ABM, you can define several activities as home activities.
