Re: [sumo-user] MoST roundabout congestion
several suggestions:
- use setStop instead of setSpeed(0) to model your accidents. Then you can still make use of teleports to avoid deadlock (also other vehicles will react more intelligently to the stopped vehicle).
- use sumo option --ignore-junction-blocker to resolve deadlock on junctions after a given time
- create a mini-scenario that showcases roundabout deadlock and create a bug report

regards,
Jakob

Dear Pascal,

thank you for using MoST Scenario.
That problem with the roundabouts is well known and I never managed to actually solve it without playing with the time to teleport. 
Additionally you can try to change the lcCooperation and lcPushy parameters too. Unfortunately, I never found a single configuration of parameters that would work fine in all the situations.
Anyway, Jakob already made some changes for the lane changing behavior in the roundabouts. You can find most of them in the issues on GitHub (https://github.com/eclipse/sumo/issues?utf8=%E2%9C%93&q=is%3Aissue+roundabout)

If you need more help don't hesitate to contact me.

Best Regards,
Lara

Dear sumo users,


I'm trying to use Monaco SUMO Traffic for a simulation. When I did a first basic simulation, I realized that the roundabouts get pretty congested - most of the times because cars are not moving forward, although they could. Had anyone else the problem before and know a solution?

For Example: Have a look to the car in the roundabout down on the right side, which is not continuing driving. I tried to solve the problem with TLS in the roundabout, but unfortunately it didnt work so well.


Because I actually want to simulate some accidents with setSpeed to zero, I can't set the time to teleport low and I set the collision.action to none.


Thanks in advance!


Best regards,

Pascal
