Re: [sumo-user] Different lengths for lanes of internal edge
There is currently no simply way to achieve this.
However, you can *cheat* by defining a tiny kink in the outgoing edge which classifies the connection as turn (see edge attribute 'shape' in the attached file)

Hi sumo users,

 

I am trying to implement an additional right turn lane for the model of an intersection. I noticed that the lanes of the internal edge of the junction, where the first single edge changes into an edge with two lanes, are automatically set to the same length by SUMO. In the documentation I read that this is expected since the lanes of internal edges are always the same. But I have also seen that it is possible for double-lane turning that the internal lanes have different lengths. So can this also be realized for an edge where I have a connection with straight direction? To reflect my model correctly, it is crucial for me that the right-turners really drive this -even if minimal- additional distance compared to the vehicles that only drive straight ahead. I have attached a minimal example to illustrate my point and added my expectation as a comment.

Can anyone help me with this?

 

Best regards

Meret
