PTV Visum - Frequently Asked Questions (FAQs)
Why is the Origin Wait Time (OWT) assumed to be zero in the timetable-based assignment?
In a timetable-based assignment, the passenger is assumed to know the departure times, and thus he has the opportunity to go to the stop exactly the right time, resulting in a zero wait time.
You can however setup an adapted origin wait time in the impedance settings, to be added to the perceived journey time (PJT). This adapted origin wait time is constant for all connections available to an OD pair, depends on the service frequency, can be limited to a maximum and is used for the skim matrix. (See manual 'Adapted skims of time for the timetable-based assignment').
