Demand matrices for used demand segments can be calculated based on path sequences. To do so, use the procedure Calculation of demand from path sequences (User Manual: Calculating demand from path sequences). Prerequisites for this calculation are:
- Path sequences with volumes and an assignment of used demand segments for the paths must be available.
- Demand matrices for subordinate demand segments must exist and they must be defined as assignment matrices of the respective demand segments.
- The demand matrices must be editable, as demand might be added.
The demand is calculated as follows:
For path sequences in a path sequence set, for each OD pair of consecutive path sequence items, the volume of path sequence - divided by the occupancy rate of the demand segment used - is added to the value of the matrix specified as assignment matrix for the demand segment used (User Manual: Managing demand segments).
