Re: [sumo-user] How to remove yielding behavior at intersection?

Attribute pass is only applicable for lane-to-lane connections. You need to specify attributes fromLane and toLane.

Dear Jakob,

I've including all the xml files in the attached zip. The command I'm running is `netconvert -c  kjtro10_20200304-1146211583351181.246513.netccfg --output-file=test --no-internal-links="false"`. When I look at the output `test` file, none of the connection items have a "pass" flag. 

Best,

pass="true" is working fine in my tests. It is written as pass="1" in the .net.xml file. Please post your files (input and resulting network).

Thank you for your responses, Jakob and Albert. I have a follow up question.

When I specify connections for the roundabout edges with `pass: "true"` in my con.xml files, then use netconvert, I don't see the value "pass" anywhere in the resultant net.xml file. Do you have any idea why this is? Thanks a ton.

You can disable yielding behavior if you set the connection attribute pass=true for all connections that enter the roundabout. https://sumo.dlr.de/docs/NETEDIT.html#inspecting_connections

Hi Kathy,

Greetings from Mountain View!

I haven't used roundabouts, but if you make a roundabout using edges, you could make each junction a zipper junction so that the vehicles would alternate while merging. Otherwise, the vehicles are likely to become deadlocked if none has priority over another.

Regards,
Albert

Dear SUMO community,

I'm attempting to design a roundabout scenario with zero priority / yielding behavior. Specifically, consider the intersection that occurs between a roundabout edge (E1) and an edge that enters the roundabout (E2). Normal SUMO / roundabout behavior would induce vehicles attempting to enter the roundabout (on E2) to yield to vehicles on the roundabout (on E1). I'd like to get rid of this yielding behavior. 

How might I do this? Via setting a particular speed mode or edge mode? Thanks for your help!

All my best,
