_______________________________________________Dear SUMO team,
I have found the answer to the first question. It seems to be a limitation. I will tune the lane-changing parameters for cars to avoid swirling movements.
Regarding the second and third questions, we appreciate it if you could share some insights with us.
Thank you very much.
Best,
Ying-Chuan

Subject: Sublane-related question
Dear SUMO team,
Below several questions we have regarding the sublane model:
1. Is there a way to still use LC2013 in the sublane environment for cars? Otherwise, cars exhibit weird behavior when the lane is much wider than their width.
2. What does bit11 and bit10 in the lane change mode mean? If it is disabled (set to 00 = do no sublane changes), would any of the lane changes between sublanes (other bits, like strategic, cooperative, speed gain, etc.) still take place?
3. In the attached package, when the bikes go from the upstream edge without bike lane “0203” to the downstream edge with a bike lane “0304”, they should ideally align to the right strategically before entering “0304” so that they can be on the bike lane (index 0). However, we see that some of them would not actually align or fail to do so. They then end up on the car lane (index 1), which is actually disallowed for bikes. For example, vehicle id 1.5, 1.19, and 1.24. By checking their status, I found it is written that they are located on the bike lane although actually (visually) being on the car lane. Is this an error? How could we prevent this from happening? Can this be guaranteed without tuning the lane changing parameters?
Thanks in advance for the answers.
Best regards,
Ying-Chuan
