Attributes of desired speed distributions

  • ►  On the Base Data menu, click > Distributions > Desired Speed.

The Desired Speed Distributions list opens.

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

Note: In lists, you can use the  Attribute selection icon to show and hide attribute values (Selecting attributes and subattributes for columns of a list).

The list contains the following attributes:

Element Description
No Number of desired speed distribution
Name Name of desired speed distribution
Lower bound Minimum desired speed
Upper bound Maximum desired speed

By default, the Units currently set under Network settings are used (Selecting network settings for units).

Showing and editing dependent objects as relation

The attribute and attribute values of this base data type are shown in the list on the left, which consists of two coupled lists.

1.  In the list on the left, click the desired entry.

2.  On the list toolbar, in the Relations list, click > Data points.

The list on the right contains attributes and attribute values of base data objects allocated to the base data object selected in the list on the left (Using coupled lists):

  • Data points: Individual data point values of speed distribution. For predefined distributions, at least two points are defined by default: Data point 1 for minimum desired speed and the last data point for maximum desired speed. You can insert additional data points between these data points. These data points are then displayed as intermediate points in the curve (Editing the graph of a function or distribution).
  • x: Desired speed at data point in curve.
  • At data point 1: Minimum desired speed of selected desired speed distribution
  • Desired speed of additional data points, if defined for this curve
  • At last data point: Maximum desired speed of selected desired speed distribution
  • FX (f(x)): Probability of desired speed x at data point
  • At data point 1: 0
  • If additional data points are defined for the curve: Probability of desired speed x at data point
  • At last data point: 1

Speed distribution is monotonically increasing. This is why each FX value must be greater than or equal to its preceding value.

3.  Enter the desired data.

The data is allocated.
