Re: [sumo-user] Retrieve edge shape via TraCI

Hi Jakob,

Thank you for your suggestion.
However, the sumolib is a Python library and thus (usually) only accessible from Python code, right?

Of course, I could also use any kind of C++ XML parsing library and parse the net.xml file myself. I would just have preferred a solution similar to how existing parameters are exchanged between Veins and SUMO.

Best regards,

you can retrieve static information about an the network via sumolib: <>
Relevant calls:
- edge.getRawShape (shape attribute of the edge)
l- ane.getShape (lane shapes derived from the former)

The spreadType value currently isn't stored within the edge objects but adding them in <> should be trivial (pull requests welcome).

    For a new model, I need to retrieve the edges' shapes (and spread type)

    Unfortunately, the two parameters do not seem to be available via

    Could you maybe give me a hint about what would be the best way to get
    these values? I have no problem with extending the code, but it seems
    like I would have to make (profound) changes at many places. Therefore,
    I wanted to make sure that I don't overlook an easier solution.
