Link (segment) Output Property Support

Output properties that can be activated for the output type: Link (segment).

Some output properties are not only contingent on the output type but on the combination of output type and PLANit traffic assignment component, such as, for example, the type of traffic assignment. For those specialised output properties, we direct the reader to the appropriate page of the PLANit component where these properties are listed.

We list the supported output properties for link (segment) ordered by their priority (id, input, output).

The Output property column lists the enum that is used to uniquely identify the property, whether it be in Java or Python.
