  • Thread-topic: Lane hopping and emergency braking at zipper


I am using a zipper lane driven by TraCI controlled vehicles. This zipper lane reduces three lanes to two. The lane changes are continuous. The TraCI vehicles can merge at any point on the zipper lane or simply follow the lane and merge as it ends. Once the vehicles have merged, control of them is returned to SUMO.

I find when vehicles choose to change lanes late on the zipper lane, they have two problems.
  1. Occasionally, they will emergency brake. I receive an error message about the lane ending. I assume this is in reference to either the to or from lane ending as the moving vehicle moves onto the zipper junction during the lane change. 
  2. They occaisonally cross two lanes instead of the intended one and thus end up on the left lane on the reduced side instead of the right.
How might I configure my setup to avoid these issues?
