Can "Cadyts" use for carsharing?

Hello,

I would like to know if Cadyts can use to automatic calibrate for carsharing? Just like the "one way" carsharing, I have the borrowing and returning amounts of carsharing stations.

Thank you very much.

In principle yes, but not without (1) really understanding how the implementation works, (2) capability to program Java, and (3) willingness to debug in small steps.

Technically: If you have some data from reality, you need to set up the corresponding measurement in the simulation. In your case, number of borrowing and returning cars at stations. You also need to set up the cadyts {{PlanBuilder}} such that it works in terms of "stations" rather than "links". Then, in each iteration, cadyts will compare the simulated with the real numbers, and via the planBuilder compute a score correction for each plan. This score correction eventually pushes plans which correspond to measurements to high probabilities, and other ones to low probabilities.

I cannot say how the car sharing contrib and the cadyts contrib will interact in unexpected ways. There is probably also nobody who knows both contribs well.

Hi Daoge,

I might be able to help you with the carsharing contrib, but I would need some more information.

The differences could occur for many reasons. Maybe your demand patterns are not the same as in reality?. Did you set up the price structures for carsahring? How do you assign carsharing membership? Which version of carsharing contrib are you using? How do you set-up your scenario?

Unfortunately I could not help you with cadyts since I have no knowledge of it.
