Re: [sumo-user] Crashing vehicles intentionally

Thank you for your answer Mr. Erdmann.

I can generate collisions with varying mingap distances and maxspeed conditions. However I can not do it when the distance is set to zero and have a physical collision.

I have tried increasing the speed as well and changing the model to IDM,W99 and change their parameters as well to create unsafe reaction conditions.

So my problem is not in the warning,this is issued, I can't actually create the crash in the simulation. I think I do not find the correct correlation in the parameters.

As far as I understand the safety checks can only be disabled in TraCI so my problem could be that I use sumo. But I am not trying to generate the collision at a specific time. My understanding may be incorrect and I would be happy to be wrong in this case.

Thank you!

Hello everyone!
I would like to ask a question regarding collisions.

I am trying to create collisions, but with mingap==0.

I can create collisions but the vehicle(s) always avoid the physical collision in the scenario.

I am working on a simple scenario with four vehicles in a highway of one lane. The length is two km. Every car departs on max speed (tried from 30 to 60 m/s) and the first stops after a km suddenly. I have tried changing some parameters like tau, but I was unable to do what I am trying to do and I couldn't find specifically what I am looking for.

Thank you very much!
