["Charis Chalkiadakis" <charcal@xxxxxxxx>]

Dear Jakob,

 

Is it also possible to use counts for multiple means at the turn-count data additional file, as proposed in the previous e-mail of yours for the edge-count data additional file?

 

The file used right now is structured as follows and I have created multiple turn-count data additional files for each means of transport (i.e. passenger car, truck).

 

<interval id="warm" begin="0" end="3600.">

<edgeRelation from="249466774" to="658270072" count="4384"/>

<edgeRelation from="658270072" to="658270073" count="3214"/>

 

Thank you in advance.

 

Kind regards,

Charis

You can write the count value to any attribute you wish and you can use multiple attributes as well (i.e passengerCount="500" truckCount="42")

When you call routeSampler, you can specify the attribute to use for that run i.e.  --edgedata-attribute passengerCount

Dear Jakob,

 

Thank you very much for your prompt reply. I have one question concerning the methodology for routeSampler.py tool to be able to generate the route file. When structuring the edge data additional file, as described in the SUMO Wiki, how can I integrate the counts from the vehicle detection stations in the file that I will structure?

 

Kind regards,

Charis

I recommend using routeSampler. Make sure to use the latest development version because routeSampler has received numerous improvements since release 1.5.0 (https://sumo.dlr.de/docs/ChangeLog.html#enhancements)

The calibrator approach has known problems when trying to export the generated routes to a scenario that runs without calibrators (https://github.com/eclipse/sumo/issues/5826).

 

regards,

Jakob

Dear all,

 

I am trying to generate routes for a given network by using edge-based aggregated data from vehicle detection stations. In the SUMO Wiki, I found two methodologies/tools which may lead to exporting the route files: routeSampler.py (https://sumo.dlr.de/docs/Tools/Turns.html#routesamplerpy) and a general methodology with route probe detectors and calibrators (https://sumo.dlr.de/docs/Simulation/Calibrator.html#building_a_scenario_without_knowledge_of_routes_based_on_flow_measurements).

 

My first question is: which of the aforementioned shall I use for exporting the rou.xml file for my network?

 

Kind regards,

Charis
