If a period that is shorter than the analysis period shall be analyzed for the temporal differentiation of calculation results, a time interval set can be defined as the base for the analysis time intervals (Using Visum: Defining a time interval set as analysis time interval set). The analysis time intervals must lie within the analysis period. They have to neither be consecutive nor of the same length. However, the analysis period must lie within one day, so it cannot contain a change of day. Provided that attributes can be assigned on a time basis, the share assigned to each defined analysis time interval can be identified separately.
In addition, you can show aggregated data across multiple analysis time intervals. For this purpose, you can create additional time interval sets with correspondingly rougher time intervals. You can use the attribute selection to aggregate attributes with a specification using analysis time intervals to time intervals of other time interval sets by selecting an aggregation function. With this procedure, values that exceed one day can also be output.
In PrT, evaluations broken down by time slices can only be made for dynamic assignment DUE, dynamic stochastic assignment and simulation-based dynamic assignment (SBA) (Dynamic User Equilibrium (DUE)), (Dynamic stochastic assignment and Simulation-based dynamic assignment (SBA)). The reason is that only in those assignments, the traffic demand can be time-varying. Therefore, evaluations for analysis time intervals within the analysis period can only be made in the course of these procedures. The link volume of the rush-hour traffic from 7 to 9 am can thus for example be evaluated separately.
In PuT, evaluations broken down to time slices are only possible for the timetable-based assignment procedure. In the timetable-based assignment procedure however, there are no connections that are fixed in time, so that it is not possible to apply assignment results to a specific analysis time interval.
