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

Hi Jakob,

Thank you for your answer.

I am already querying the lanes' shapes (for a different purpose). Just for the current requirement, the edges' shapes would have been helpful.

So, I guess I'll just go with the lanes or query the net.xml directly.

Best regards,

The function traci.lane.getShape  is part of the standard TraCI API (though I'm not sure if Veins has exposed this yet). If you really need the original edge reference line, there is some geometry code in sumo which you could use to compute it from the lane shape (utils/geom/PositionVector::move2side)

    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,
