With the aid of the calendar, the modeling of transport supply (in public transport and for the DUE procedure in private transport) and demand (for the dynamic procedures of private transport and the headway-based and timetable-based assignments of public transport) can be refined considerably (Using Visum: Selecting a calendar ). It is not only possible to model any day, but also to manage any combination of weekdays or individual days. The calendar is global, i.e. only one of the following three calendar options can be applied to the entire model. Use of the calendar is optional. The following options can be selected for a network model:
- No calendar
The transport options for one day are indicated. The analysis period is thus automatically one day and cannot be edited by the user.
- Weekly calendar
The demand (for the dynamic procedures of the PrT and for the headway-based and timetable-based procedures of the PuT) and the PuT supply can be differentiated for the individual weekdays Monday to Sunday. It is possible to specify for each vehicle journey section weekdays on which there will be a service. The analysis period can be any time period of entire days within the week (such as Monday to Friday).
- Annual calendar
Valid days can be defined for any day of the year. The analysis period can be set to any time period (in entire days) within the calendar period (e.g. 14th July 2008 to 20th July 2008).
The calendar takes effect in the following procedures (all other procedures are not affected):
- Dynamic assignment in PrT
In the Dynamic stochastic assignment and DUE, traffic supply can be time-varying. Time-varying attributes are used (Time-varying attributes). When using a calendar, valid days can be specified for these time-varying attributes, on which they should take effect.
- Assignments in PuT
Valid days are allocated to and affect single vehicle journey sections.
- PuT analysis (Operation PuT operating indicators)
- PuT passenger survey
