Hi,

I'm trying to calibrate a model by using cadytsIterate.py but the information in the documentation isn't clear enough for me.

I have:

1. The original OD matrix, which is used to create a trip file.

2. A *.rou.alt.xml file which is the output of running duaIterate.py using the OD matrix from 1.

3. observed counts on some links, in the edge_data format here.

<data>

  <interval begin="0" end="3600" id="observed">

    <edge id="-807471204" entered="209" />

    <edge id="-305546124" entered="955" />

  </interval>

</data>

 

What I need to do is to adjust the demand such that it matches the provided observed counts to the best it can be. (trying to achieve GEH<5 in at least 85% of them)

Could you please provide some details on the right command/parameters and the correct formats of the data mentioned above?
Is it expected to change the original OD matrix? or it preserves the matrix and just redistributes the routes between the O-D?

thanks in advance,

Rehab
