I am using Cube Avenue to develop a Dynamic Traffic Assignment(DTA) model. I want to give variable OD (some proportion of daily OD matrix) for different time segment of a model run.
Elaborately I would say that I have OD matrix for a whole day trip. Now I want to give a different proportion of OD pairs in the different time segment of a model run. Is there any method to do that?
Please guide me in this regard. I will appreciate your efforts.
Have you managed to do this yet? The most common way to do this is to use a matrix program before the DTA to profile your daily trips into time segments. Avoid doing this directly at the assignment stage as it's less transparent and harder to audit/check.
In the Cubetown demonstration model there is an example in the Avenue Application which takes vehicle trips and converts into peak hour trips (program 2). This isn't quite the same as what you need but it's similar i.e. take a set of input matrices, apply factors and output a matrix. Note that the demand for this example is hourly.
Thank you Oliver. I have managed to do it.
