Re: [sumo-user] Mismatch between chosen lane using TraCI and lane change state
Hello again, Thank you for your response. I am reattaching the zip file with the following files renamed: - simulate-sublane.sh renamed to simulate-sublane.txt - sublanechange.py renamed to sublanechange.txt >>> ex1: looks ok: the vehicle could change lane but just doesn't want to (left/right are missing from the state) - couldAndWant requires both opportunity *and* intent The information missing from the state is what is causing my doubt. I can't tell *why* it doesn't want to after being commanded by TraCI to do the same. Not sure where the 'want' even arises from - as in SUMO wants to do something else? That is if there is an opportunity to lane change (couldChangeLane is True), and TraCI tells it to (wants to change Lane), should it not follow the command? >>> ex4: like ex1 but the screenshot doesn't show the agents in question Agent f.4 is just inserted into the lane with index 1 at the beginning of the lane, and agent f.5 is one of the vehicles in the middle of the lane with index 0. The vehicle ids are shown in red on top of the vehicles. I'm not sure if the screenshots were filtered in some way. Looking forward to your response.

Hello, Please let me know if there is any additional information required? I could also make screenshots for the given conditions if needed.
