Transport system-based assignment: Basis tab

Element

Description

Origin zones

Via these two entries you may restrict the calculation to the demand of origin zones with selected numbers. Thus only the selected rows of the demand matrix will be assigned.

Note

If both entry fields are empty, Visum will assign the entire demand matrix.

If only a single zone number is entered, Visum will use this value as the upper or lower limit respectively (half-open interval).

Calculate assignment

If this option has been checked, new PuT routes are determined and loaded on the basis of transport systems.

If this option has not been checked, the assignment is not performed.

Note

You may, for example, just calculate skim matrices.

Calculate skim matrices

Select this option to calculate the skim matrices selected in the Skim matrices tab (Calculating PuT skims).
