Hi,

There is no built-in support for lanes. If your graphs are not very dense, you can get good results by running LayeredLayout with Orientation = Horizontal to assign the nodes X coordinates, and then loop over the nodes and set them at Y position corresponding to their lanes. You will also need to update the links after that, say by aligning their end points to the middle of the node borders and calling Route.

I hope that helps,
Stoyan
