PTV Visum Demand Model
PTV Visum Demand Model
(OP)
Hi fellow traffic engineers!
I hope there are some modelling experts in here!
I'm currently developing a traffic demand model with PTV Visum 2020 and I wanna include Bikesharing in my model.
With the vehicle Sharing function, it's easily set up.
So far so good. My problem starts when I try to calculate my PuT skim matrix. The error code "no OD pair shows demand > 0 within assignment time period. No connections calculated."
This error usually occurs when when the assignment period which is valid for the demand don't overlap, which they do in my my model.
I can't fimd the cause of the Problem. I don't even calculate an assignment, just a skim matrix.
I hope there is someone here, that can help me with my problem.
Best Regards jon
