Hi,

 

Please check here: Cadyts - SUMO Documentation. It helps you to prepare the traffic measurement (observed counts) file and it also provides the information how to run cadytsIterate.py.

 

You might need to turn on the duarouter option --keep-all-routes to get route alternatives as many as possible. It should/could be helpful to increase the calibration accuracy, since cadyts only considers the routes in the given route alternative file.

You can choose either to keep the amount of the original traffic demand or to adjust it according to the provided traffic counts. For the latter one, you need to set the demand scale (-S), e.g. 1.5 or 2 . Trips will then be cloned accordingly. The cloned trips will be used by Cadyts according to traffic flows and given counts. If the demand scale is set to high, you may create unrealistic traffic jams in simulation.

 

Some related experiences gained when using cadytsIterate.py can be found SUMO_proceedings.pdf.

 

Regards,

Yun-Pang

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
