User-defined time interval sets and time intervals
In general, time interval sets and time intervals are used for input and output of dynamic data.
Several time interval sets can be created for which time intervals are defined. The time intervals of a set must not overlap, but must not cover a complete period either.
Exactly one of these time interval sets contains the analysis time intervals that are used for dynamic outputs from procedures, for example, for:
- Volumes in dynamic assignments
- Supply data such as the number of service trips per interval when calculating operational indicators
In addition to the values for the analysis time intervals, values for the analysis period and the analysis horizon are also calculated, taking the projection factors into account.
If the time interval set with the analysis time intervals is changed, result data is discarded. It therefore makes sense to create additional time interval sets with time intervals for input data such as count values or other survey data.
For user-defined attributes with a time dimension, these time interval sets can be used as subattributes. In this way, for example, you can manage and directly use input data for dynamic matrix estimation, such as passenger trips per 15 min and passenger kilometers collected per hour. If you want to compare collected data with result data of the procedures, you can aggregate the data in the Select attribute window to time intervals of a different time interval set to achieve comparability.
