Re: [sumo-user] How to add overtaking in SUMO
Harald & Jakob

I see now. I was able to adjust the 'opposite' lane attribute now. Thank you for the clarification.

My predicament is that I would like to use netconvert, but I have a limited amount of time. I would rather not have to build out a whole new road network. Also, I was just wanting specific lanes in my network to allow overtaking, specifically the road segments at certain bus stops. Aside from these segments, those are the only places I would allow overtaking to occur.

I was trying to type in the field named 'opposite', but it wouldn't let me adjust the parameter to put in the lane id. I also tried using the 'edit parameter' box on the left hand side of netedit, but nothing happened. However, I noticed that the opposite parameter seems to be locked because in the 'show parameter' pane in the dynamic column there is a red X on it (please see below). Do you know where I could go from here?

Thank you

You can put the id of the opposite-direction lane into the 'opposite' field. This only works for "innermost" pair of lanes (those with the highest lane index of both directional edges).
It's recommended to let netconvert option --opposites.guess do this job, though.

Thanks Jakob, but where can I adjust the lane attribute 'opposite' in netedit?

I see where you can view the lane attribute 'opposite' as a parameter (i.e., show parameters when I left click the lane), but I can't edit or adjust it.

Never modify a .net.xml file directly.
To support opposite direction driving in a network, run:
netconvert -s old.net.xml --opposites.guess -o new.net.xml
You can also set lane attribute 'opposite' in netedit.

Would the line of code for opposite lane driving look something like what is depicted below if it were implemented in a .net file?

Hello Everyone

I currently have a .net file that I am thinking about adding overtaking behavior. The idea is when one bus comes from behind another bus on a different bus route but at the same stop I would like the bus behind to overtake the other if the other bus is taking too long. Is there a way for the bus behind to overtake the leading bus (i.e., teleporting ahead of the leading bus)?

I have looked at the documentation on opposite-direction driving, but it seems like you can only explicitly call "neigh" in an .edge.xml file rather than a .net file. The reason why I asked if it is possible to do this in a .net file is because I already have a functioning .net file established and I would like to edit it from there.

For reference, my .net and additional files are attached to this email. The place I was trying to add overtaking is at lane -467228692#3_1, where the lane 467228692#3_1 is used to overtake at the bus stop.

Thank you in advance for your help
