Timetable-based assignment: Choice page

On this page, you define how to distribute the demand to the single connections.

Element

Description

Choice model

From the drop down list, select the appropriate choice model. The model controls the distribution of the demand to the individual connections according to the connection impedances. You can edit specific parameters for each choice model (Fundamentals: Independence of connections).

Note

To calculate the Impedance LogSum skim, you must select the Logit entry (Timetable-based assignment: Skim matrices page).

Use independence

If this option is selected, the independence of the connections in the choice model selected is taken into account (Fundamentals: Independence of connections).

Note

The independence of a connection codes the information whether there are interesting contemporary connections which could alternatively be used by passengers. When determining the value, arrival and departure times of connections are always regarded. Optionally, also the qualitative skims perceived journey time and fare can be included.

Maximum time slot

Over this maximum period of time, connections can influence each other. The value must be greater than null.

Impact of perceived journey time and fare

Value indicating the impact of PJT and fare for the independence calculation (0: no impact, 1: maximum impact). This value complies with variable c.

Impact on connections of high quality

Value for the impact of worse connections on a better one.

Impact on connections of low quality

Value for the impact of better connections on a worse one.

Note

The value entered for impact on connections of high quality may not exceed the value entered for impact on connections of low quality.
