[sumo-devel] NBEdgeCont::splitAt(), split on left to model left turn pocket

[Yifeng Z. <ze...@li...>]

Hello All,
I was trying to model the left turn pocket. And I use NBEdgeCont::splitAt() function to split an edge near the junction/intersection:

			myTestEdgeCont.splitAt(dc, MyTestEdge, distance_to_split_from_usn, n3, "e_first_"+std::to_string(edge_id), "e_second_"+std::to_string(edge_id), 3, 4, -1, 1);

I specified 1 lane that is added on the left side of the edge (changedLeft = 1), but as shown in the "LeftTurnPocket.PNG" picture, the lane added is still on the right side of the edge.

Am I doing anything wrong? Would you please let me know how I can get the left turn pocket as shown in the "LeftTurnPocketDesired.PNG" picture?

Thanks,

Yifeng
