1) PRINT MATRIX CELLS/SECTORS TO THE LP FILE
Produce a “standard” matrix listing to the line printer file intended for later analysis.
2) PRINT/DUMP ROW AND COLUMN TOTALS
Produce a listing of row and column totals to either the line printer or a file.
3) DUMP MATRIX/SECTOR DATA TO A .DAT FILE
Output matrix file (in toto) to an external ascii (e.g. .dat) file. This may be either in the standard SATURN format or in a format set by the user, e.g., so as to be able to “export” a matrix to a spreadsheet. See also 3 above for the reverse operation.
4) DUMP/RE-CODE THE INTERNAL MATRIX TO A UFM FILE
The internal matrix file may be output (in to) to an external binary .UFM file for use in other SATURN programs. This is the normal way to “save” a new matrix. As in option 2 the matrix file may be output “as is” or transformed in various ways (e.g. by recoding zones).
5) STACKING AND UNSTACKING .UFM FILES
A set of externally input square matrices may be combined together and output as a single “stacked” matrix file (see 10.2.4) or, alternatively, if the internal matrix is itself a stacked matrix it may be split into a full set of output individual matrices or a single matrix from a single level.
6) MATRIX DEMAND CALCULATIONS
A prototype set of “formal” transport demand model steps such as distribution or modal split are carried out using a combination of input trip and cost matrices. These parallel the standard elastic demand options within SATEASY (see sections 7.4 to 7.10) and demand calculations by time period (see 17.12).
