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, Alex On 5/4/22 16:38, Jakob Erdmann wrote:
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)regards, JakobAm Di., 3.

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.
