Re: [sumo-user] Problems with Simpla platooning: platoon forms in only one lane of a two-lane road


Please see my model in the attachment. The major issue is that the platoons mostly appear in one lane, which is the slower lane.

You should upload your model for easy understanding

I am using Simpla to generate platoons on a two-lane road. However, unless in quite a dense traffic, the platoons are mostly formed in the right lane and there's little traffic on the left one. 

I set the left lane with a higher speed limit and set a higher value for lcSpeedGain to be 15, trying to encourage vehicles to switch to the faster lane. By doing so, the platoon appears on the left lane but is much fewer than the right one. And it appears that some vehicles change to the right lane (slower lane) and then form the platoon. This is in contrast to real-life conditions. Additionally, removing the platooning model, the traffic is evenly distributed in both lanes. So I'm wondering whether this is the setting of the Simpla model or whether I missed some parts.

Thank you and looking forward to hearing from you.
