Re: [sumo-user] Import connections from Opendrive

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

- turnarounds are added by default. This can be disabled by adding the option --no-turnarounds

- surplus left turns are added from road "102". As far as I can tell, this road does not have any outgoing connections at all. As stated earlier, netconvert will guess connections whenever an edge does not have any outgoing connections specified. It might be useful to add another option for preventing this behavior. However, edges that reach an intersection and then do not continue at all should be very rare so I would not consider this a priority.

- I could not find surpluse straight connections. Please let me know which ones I missed (also If I missed further surplus left turns)

regards,

Jakob

Here's the file.

Use --no-left-connections then unwanted left-turnings are gone, but there are still some straight connections and turning-back connections added which are not in the opendrive file.

Regard,

Netconvert should not build any connections for edges that already have OpenDrive-defined connections.

If you can send me the input file I will investigate this is a possible bug.

Importing internal lane shapes directly is not yet supported but should be possible in principle (https://github.com/eclipse/sumo/issues/4331).

As a workaround, you could specify these lane shapes in a .con.xml file.

Dear SUMO users,

I have noticed that SUMO adds more connections when building network process, after opendrive importing. Is there a way to only use connections from opendrive and not generate new ones? And how to preserve the shape of internal lanes from Opendrive?

Thanks!
