PTV Visum - Frequently Asked Questions (FAQs)


How can I determine turn travel times?

Turns needs the same correlation between capacity and travel time as links. The only difference is that a turn does not have a length and the travel time is given as t0 (input value) plus a turn time addition (from the volume-delay functions).
The TSys-specific turn addition T0_PrTSys is a calculated value which results from the attribute t0 and the result of the check whether the turn is valid for that TSys.
