Removing zigzags from a route course

You can remove zigzag courses of one or several line routes in the network editor. The function checks the route one after the other, starting from a starting position, for zigzagging. Visum iteratively removes zigzag courses until no more can be removed without creating a new zigzag course. Trivial zigzags are also removed. These are zigzags, each of which has profile points only on one of the links traversed several times.

Note: The functionality is also available for system routes. It is described below for line routes.

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

2.  Mark the line route whose zigzags you want to remove.

3.  Right-click in the network display.

A shortcut menu opens.

4.  Select the Remove zigzags entry.

One or more queries are displayed, listing the links that have been traversed multiple times and that must be removed from the course to remove the zigzags.

5.  Confirm the queries.

The zigzag courses of the marked line route are removed.

Tip: Alternatively, you can remove zigzags in other places in Visum: In the Linie route editor window (Editing line route items) In the windows tabular or graphical timetable (Removing zigzag from the stop sequence in the tabular or graphic timetable) In the window Edit sequence of stop events(Editing the stop sequence) In the window Timetable lines: stop sequence (Removing zigzags from the stop sequence) During a network check (Checking the network)
