The Table 163 shows the available frequency skims.

Skim |
Definition |
|
Number of transfers (NTR) |
Number of transfers between origin and destination stop point (per connection). [-] |
|
Service frequency (SFQ) |
The service frequency indicates how often a relation is traversed. A flow problem is solved on the graph of all determined routes. Service frequency thus depends on the "weakest" part in the transport supply. The parameter Number of arrival time points shows the definition valid until PTV Visum 2020. |
|
Number of operator changes (NOC) |
Number of transfers with different operators of previous and next path leg. [-] |
|
Number of fare zones |
Number of traversed fare zones. The skim depends of the ticket type(s) used for the connection and returns zero if no zone-based ticket type is used. [-] |
|
Number of arrival time points (NATP) |
The service frequency indicates the number of times a relation is traversed. For the timetable-based assignment, the service frequency is defined as the number of different arrival time points for connections departing in the assignment period and in the post-assignment time period, but before a possible second occurrence of the start of the assignment period. The latter means in particular that the post-assignment time period is not taken into account if you do not use a calendar and define an assignment interval from 0:00 to 24:00. To the headway-based assignment, the following applies: On the graph of all determined routes, a flow problem is solved. Service frequency thus depends on the "weakest" part in the transport supply. |
