[sumo-user] Turning cars block the intersections

[Sasan Amini <sasan.amini@xxxxxx>]

Dear all,

 

I have a relatively large network in which I often face a problem at intersections. As you can see in the attached screenshot, left-turning cars stop in other lanes where they cannot turn left and stand still blocking the way for the through stream. My questions is why would they even select an unsuitable lane from the upstream road connection? How can I avoid this? There are no cars generated in this link and all vehicles come from other “source” links and go to some other “sink” links. I have no internal links and it only happen when the traffic volume is big, for small demands this doesn’t happen. Is it related to lane changing or rerouting decisions?

 

Thanks for the help.

Sasan
