When comparing the PuT demand and the number of trips, I noticed that not all of the demand was assigned. How can I calculate the demand that was not assigned?
You can save the demand that was not assigned as a so-called “remaining matrix”. To so do, select File -> Save as -> Origin-destination matrices. Then choose the demand matrix of the assignment and enter a new file name for the remaining matrix. In the Write matrix dialog, click Assignment matrix and under Matrix, select the Remaining matrix check box.
