Check ridership data for plausibility
In general, the ridership data you import is incomplete. You need to check and complete the data records, if required, by adding plausible data for missing information (Fundamentals: Plausibilization of survey data).
Plausibilization includes the following steps.
- Validity check of the survey path leg
- Validity check of the preceding path leg and the succeeding path leg
If plausibilization of a survey path leg is not successful, both the preceding and the succeeding path leg will be ignored.
The validity check can be run several times, in order to check the ridership data data sets successively with hard-to-meet criteria, which become easier and easier with each run.
Note: After plausibilization, a plausibility status is allocated to the survey path leg (E1 – E9), to the preceding path leg (V1 – V9) and to the succeeding path leg (N1 – N9) of each data record. Furthermore, each data record stores an overall status. With 100% plausible path legs, this overall status is plausible (G1), otherwise it is not plausible (G9) (Fundamentals: Plausibilization of survey data). |
1. Import the desired ridership data (Loading ridership data).
2. On the toolbar, click the Open 'Procedure sequence' window button.
The Procedure sequence window opens.
3. Add the procedure Plausibilization of survey data of the PuT passenger surveys category to the position of your choice in the procedure sequence (Setting up and starting the procedure sequence).
4. In the row of the inserted procedure, click the button in the Reference object(s) column.
The Select demand segment window opens.
5. Select the desired demand segment.
6. Confirm with OK.
The window closes. In the Reference object(s) column, the selected demand segment is listed.
7. Make sure that the inserted operation is marked and click the Edit button in the Operations section.
The Plausibilization of survey data window opens.
8. Make the desired changes (Settings for the plausibility check of survey data).
9. Confirm with OK.
10. Execute the procedure (Executing procedures in the procedure sequence).
The ridership data is verified and the plausibility is checked. You can show the results in lists or in files (Viewing results of plausibilization). After plausibilization, you may use the data for direct assignment (Assignment of survey data).
