[sumo-user] Neighbouring Lanes

[Dennis U. (C) <den...@op...>]

Dear SUMO users,

I am currently working on a project that uses SUMO in Matlab via TraCI. I am stuck trying to find out how to get the lane IDs of my neighbouring lanes.
To be clear: I have a vehicle on the road. This road could have 1 - 4 lanes. Any given moment I need to know if there is a lane to my right and/or to my left.
I already had a solution by adding 1 and subtracting 1 from my current Lane IDs index and comparing the results to the complete Lane ID list of my network.
But this was way too slow.
Is there a simpler, faster way to retrieve this information?

Best regards

Dennis Uftring
