Connecting demand matrices and demand segments

For an assignment, you connect the demand (available as demand matrix per demand segment) to the demand segment of your choice. During assignment, VISUM considers the demand stored in the allocated matrix for each of the demand segments you specified.

3.  In the desired demand segment row, click on the button in the first column Matrix.

The Select matrix window opens.

4.  Select the matrix whose values you want to distribute to paths. Here, two methods are provided (Selecting matrices).
