Deleting a node

Notes: If a stop point is located on the node that you want to delete, the stop point will also be deleted. If the stop point is served by a PuT line, this line as well as its line routes, time profiles and vehicle journeys will also be deleted. Nodes with two legs are an exception to this (Exception: Deleting nodes with two legs and no stop point and connecting the links).

1.  In the Network editor window, click the Edit mode icon .

2.  In the Network window, click the Nodes button.

3.  In the network, click the node that you want to delete.

4.  Press the Del key.

Tip: You can also delete the marked node via the context menu > entry Delete.

A query opens.

5.  Confirm with Yes.

The node is deleted.

Exception: Deleting nodes with two legs and no stop point and connecting the links

If you delete a node without stop point, you can specify that the two links of the node will be connected.

Note: You cannot connect the links if there is already a link between the adjacent nodes of the node that you want to delete. In this case, the connected link would coincide with the link of the adjacent nodes. However, in Visum, identical links are not permitted.

1.  In the Network editor window, click the Edit mode icon .

2.  In the Network window, click the Nodes button.

3.  In the network, click the node that you want to delete.

The node is marked.

4.  Press the Del key.

The window Deleting nodes with two legs is opened..

Tip: You can also delete the marked node via the context menu > entry Delete.

5.  Select one of the following options:

Element	Description
Delete	If the option has been selected, the links will be deleted.
Connect and use data of link <X>	Select this option to connect links and adopt the data of link <X>.
Connect and use data of link <Y>	Select this option to connect links and adopt the data of link <Y>.

6.  When you connect links, a query is opened about how to treat stop points.

Note: This query is displayed, when from the Edit menu, you choose > User preferences > Network  > Stop points and then select Permit creation of link stop points. If this option is not selected, the node is immediately deleted.

7.  Select the desired option.

Element	Description
Delete	If the option has been selected, the stop point is deleted.
Position on link	If this option is selected, the stop point is moved from the deleted node to the link.

The node is deleted and, if applicable, the links are connected.

Note: For the new link, Visum uses the transport systems which were permitted on both connected links.
