Using simulation-based dynamic assignment, you can perform the following evaluations:
- Flow-bundle calculation with temporal restriction
- Filter for OD pairs, including the option Filter network volumes
- Calculation of dynamic skims (either departure time related or arrival time related)
For flow-bundle calculation, you can add a temporal restriction for a network object. The time reference refers to vehicles that have entered a network object, e.g. a link, within the time period specified. Vehicles that meet the flow-bundle conditions are output as flow-bundle volumes at network objects, as origin or destination traffic of zones and optionally as matrices per analysis time interval.
To calculate dynamic skims from a simulation-based assignment, you can use the procedure Calculate dynamic PrT skim matrix. Within the procedure, you can choose between departure time-related calculation and arrival time-related calculation if skims are also output for analysis time intervals. Time interval-related skims only contain meaningful values if demand actually departs or arrives in the time intervals. If this is not the case, the value is set based on OD pairs without paths.
