Re: [sumo-user] make the network circular in a non-geometrical way

Hello Jacob,
thank you for your instructions. I managed to define the shape of the non-geometrical edge and produced the following network

a) I set the function for the non-gemometrical edge as "connector" (manually to the net file, is there a more clever way to do that?) in order to distinguish it from the "normal" edges of the network.
Is it possible to not show that edge at all in sumo-gui as it is somewhat confusing.
b) If i have many such non geometrical edges (set to 0.1 m), they may intersect. If that happens sumo considers them to be on the same plane and creates an intersection at the point those edges meet.
I would like these edges to be considered at different height so that they dont intersect. Can i do that by specifying the z parameter of the edges' shape.

Thank you in advance.

Hello,
I suppose the FAQ advice for creating non-geometrical loop was misleading. My suggestion is, that you define an edge with sensible geometry (i.e. a big detour loop around the central intersection (so the geometry will look fine) and then declare it's length to be 0.1m.
Reason: netconvert will always compute geometry and if edges intersect at strange angles the network will look like a mess. (An alternative would be to manually define the geometry of the border junctions.

regards,
Jakob

Good evening,
i came across a peculiar bug when i try to close a network in a non geometrical way. If i specify the edge length as 0.1, as said in documentation it throws a warning "junction shape is to far away from the original node position"  and results in  the second photo. The only difference between the first and second network is that in the second case i specify 4 extra edges (from top to bottom, bottom to top, left to right and right to left) and set them to 0.1 length.
