Managing matrices
                                        Matrices are separate objects in Visum and part of the demand description (Fundamentals: Matrices). Demand modeling uses different types of matrices. They are edited and managed fairly similarly.
- Demand matrices contain the number of trips between zones or main zones per demand segment.
 - Skim matrices contain skim data for pairs of zones or main zones, for example travel time.
