The normalization is useful for the line blocking procedure. It ensures that each vehicle journey section has the maximum length and removes redundant vehicle journey sections. The normalization thus prevents that, during line blocking, an undesirable vehicle change takes place at a vehicle journey that has multiple adjoining vehicle journey sections that do not overlap.

Tip: You can achieve the same effect if you define forced chainings between two adjoining vehicle journey sections (Creating chained up vehicle journey sections). |
Vehicle journey sections with identical vehicle combinations are normalized as a separate group.
The normalization of vehicle journey sections is particularly useful when reading in HAFAS data.
Example: You create a vehicle journey for a bus line with two vehicle journey sections with the same vehicle combination. The first vehicle journey section covers the distance between A and B where the bus runs from Monday to Friday. The second vehicle journey section covers the distance between B and C where the bus runs every day (Monday to Sunday). If you normalize these vehicle journey sections, Visum generates a vehicle journey section of maximum length for the distance between A and C for the days Monday to Friday and a second vehicle journey section for the distance between B and C for Saturday and Sunday.
You can execute the functionality for all or all active vehicle journey sections.
1. If required, set the vehicle journey sections active that you want to normalize (Using filters to set network objects active or passive).
The selected vehicle journey sections are active.
2. In the Network window, right-click the Lines button.
The Lines shortcut menu opens.
3. Select the Normalize vehicle journey sections entry.
The Normalize vehicle journey sections window opens.
4. Specify whether you want to normalize all or all active vehicle journey sections.
5. Confirm with OK.
The vehicle journey sections are normalized.
