Re: [sumo-user] routeSampler

- increase the number of sampled routes that is given as an input

- check the sampled routes for plausibility (if they show apparent detours as in your screenshot, there may be network model errors that prevent the expected route from being used)

- check whether the sampled routes match the input counting data (https://sumo.dlr.de/docs/Tools/Turns.html#spatial_quality_data). It is possible, that the inputs force the observed result.

If none of this helps, provide more details.

Hi there,

I created the vehicle routes file using routeSampler.py with the following command:

python tools/routeSampler.py -r <input-route-file> --edgedata-files <edgedata-files> -o <output-file>

To generate the input route file, I used this command:

python tools/randomTrips.py -n <input-net-file> -r sampleRoutes.rou.xml

However, when I ran the simulation in sumo-gui, I noticed that some roads weren't used in the generated routes at all. Please refer to the screenshot below.

 I’ve noticed that in some parts of the network, vehicles are teleporting. Additionally, in one specific area (see the picture below), all the cars are trying to pass through route 1, while route 2 remains empty and available. Do you know how I can resolve these issues?

Thanks in advance for your help.
