Connecting line routes

Note: Existing assignment results are deleted when connecting line routes.

With this functionality, you can generate a new line route from two adjoining line routes. The line routes to be connected need to meet the following requirement:

  • The start stop point of one of the line routes is the end stop point of the other one.

Connecting line routes means that at the connecting stop point, the last line route item of the first line route is merged with the first line route item of the second line route. The last time profile item of the first time profile is allocated to the first time profile item of the second time profile.

For the merged line route item, the To-length is set to the To-length of the first line route item of the second line route and to the user-defined attributes of the last item of the first line route or the first time profile..

Notes: If the stop point at which two line routes shall be connected is an undirected link stop point (Creating a stop point), the outgoing line route must point in the opposite direction of the incoming one, since the line route cannot turn on a link stop point.

Existing chained up vehicle journey sections are retained.

Line routes of the same line, like the opposing directions of a line route, can also be connected.

If you want to connect line routes, proceed as follows.

1.  Open the Line routes window (Opening the Line routes window).

2.  From the list of line routes, select the one you want to connect to another line route.

3.  Right-click in the network display.

A shortcut menu opens.

4.  Select the Connect line route entry.

The Connect line route <Name> window opens.

5.  Make the desired changes.

Description

Line route to be connected

In this section, you can specify whether the selected line route shall be extended at the start or at the end.

Extend at the end with

If the option has been selected, you can pick the line route which you want to use for the extension at the end.

Extend at the beginning with

If the option has been selected, you can pick the line route which you want to use for the extension at the start.

Combination type

Edit line routes

If the option has been selected, the line, the direction, and the name of the selected line route will be used. The newly created line route is then a combination of the two line routes. The line route selected at the top of the window will be deleted.

Create new line route

If the option has been selected, the combination parameters are enabled.

Combination parameters

Dwell time at connection point

If this option is selected, you can enter a dwell time in the entry field.

Dwell time at connection point from default dwell time of stop point (0 min)

If this option is selected, Visum uses the default dwell time of the stop point.

Line of the new line route

Use the drop-down list to select a line to which the new line route shall be allocated.

Name of the new line route

Enter the name of the new line route

Direction of the new line route

Use the drop-down list to allocate a direction to the new line route.

Discard combined line routes

If the option has been selected, the two original line routes will be deleted.

If the option has not been selected, the new line route will be created in addition to the two combined line routes.

Also copy vehicle journeys

If the option has been selected, all vehicle journeys will be copied.

Notes

The copied vehicle journeys keep their original course and are thus not even lengthened if they start or end at the connecting stop point.

User-defined attributes and AddValues are copied from the selected line route.

6.  Confirm with OK.

The line routes are connected.
