| Re: [sumo-user] Causing lateral collisions while changing sublanes |
_______________________________________________I have set the lanechange mode to 0 for the vehicle that I am controlling (as I want to only allow it to change sublanes via TraCI). I notice that the vehicle goes very close to the vehicles next to it, but then it automatically brakes or does not change the sublane even though the command to change sublane is given. Also, even if there is an overlap between the vehicles, it is not getting recorded as a collision.
I have attached a snapshot of my simulation. The blue coloured vehicle is the vehicle that I am controlling. For all other vehicles, I have set the laneChange mode to 0b010001010101.
Thank you

Setting lanechange mode to 0b010001010101 is sufficient (only 1 bit changed from the default). All you need to do is send repeated changeSublane commands to move towards a neighboring vehicle. For examples, take a look at https://github.com/eclipse/sumo/blob/master/tests/complex/traci/pythonApi/lateralCollision/sublaneChanging/runner.py

_______________________________________________Hi Jakob,
Should I also set any new parameters for disabling the safety checks. Cause I am still not able to cause a collision.
I am using SUMO v1_0_1+0928-ee52d65a66.
Thank you

Hello,
there was a bug that prevented lateral collisions in the sublane model (https://github.com/eclipse/sumo/issues/4864).
This has been fixed in the latest development version.
To make use of the fix, either download the latest sources from github or wait until tomorrow to download the updated windows binaries: http://sumo.dlr.de/wiki/Downloads#SUMO_-_Latest_Development_Version
regards,
Jakob

Hello everyone,
Could you tell me if it is possible to cause lateral collisions while changing sublane in SUMO? Do I need to modify any parameters for that?
I am trying to create a vehicle model which tries to change lanes by changing sublanes. Hence for the algorithm to learn I would like a collision to occur if it changes incorrectly. I am able to create collisions during lane changes but not during sublane change.
Thank you
Best Regards
Aashik
