The ACC model has a rather narrow range of applicability. In particular, the model is known to produce collisions at the default step-length of 1s. Better results can be achieved by setting a lower step length (i.e. 0.1s).

Subject: [sumo-user] Vehicle performs emergency braking
Hello,
When I run the configuration I get the following error for many vehicles. Can anyone let me know what could be the cause of such warning and how to prevent it? Does the severity level =1 indicates high severity? Is this warning something that needs to be given careful thought since I had one vehicle involving in a collision.
“performs emergency braking with decel=-9.00 wished=4.50 severity=1.00”
I didn’t notice such huge amount of warnings in earlier version.
Regards,
V.H.Pradeep
