[sumo-user] question about change lane by config

[Yanglan Wang <yanglan119@xxxxxxxxxxxx>]

Dear SUMO,

Is it possible to make vehicles on the freeway not always stay in the right lane but scatter in the center or left lanes. Because vehicles on the right lane will restrict the merge vehicles. As shown in the screenshot, 4243, 4233 and 4442 always stay in the right lane. And even insist on the right lane after the merge point.

Moreover, I don't want to use Traci to make each vehicle change lanes because the number of vehicles is so large. Is it a method that can realize it just by setting configuration?

Thanks a lot in advance!
