Changes you make to Visum matrices remain in effect when you close the Matrix editor window. However, to save your changes permanently, you need to save them to the version file. If required, you can save Visum matrices to a file.
To keep changes made to external matrices, you must save them to a file when you close the Matrix editor window.
You can save matrices either in a binary format or in one of four text formats (Visum-specific matrix file formats).
For demand matrices, you can save the volumes of routes found by OD pair as partial matrices which just contain either the active trips or the remaining trips.

Tips: Alternatively you can save skim matrices to file automatically with the calculation (Calculating PrT skims and Calculating PuT skims). A further option: You can also save demand matrices together with the demand description (Saving demand data). |
