Defining time distributions

1.  On the Base Data menu, click > Distributions > Time.

The Time Distributions list opens.

By default, you can edit the list (Using lists).

2.  Right-click the row header.

3.  On the shortcut menu, click Add.

4.  On the shortcut menu, click the desired entry.

  • Empirical Distribution
  • Normal Distribution

A new row with default data is inserted.

5.  Enter the desired values.

You can edit the curve of an empirical distribution.

6.  If you would like to edit the empirical distribution of the time distribution in a graph, double-click the entry.

The Time Distribution window opens.

7.  Make the desired changes:

Element Description
Name Description
Left field with time unit s Minimum duration in seconds
Right field with time unit s Maximum duration in seconds

If you are using public transport dwell time to model public transport, a standard deviation = 0 s will result in a constant public transport dwell time (Calculating the public transport dwell time for PT lines and partial PT routes).

8.  Right-click in the line.

A node is entered.

9.  Click the intermediate point and keep the mouse button pressed.

10.  With the mouse button pressed, drag the intermediate point to the desired position.

11.  Release the mouse button.

The labeling for the y and x axes is adjusted.

12.  Confirm with OK.

The time distribution will be shown in the Time Distributions list (Attributes of time distributions).
