Thanks, Jakob for the reply. I understand that Krauss model makes full use of it's accel/decel values.
Regarding your comment, - ACC/CACC sometimes accelerate with less than their accel value (thereby achieving smoother trajectories) However, does one model accelerate more or less than the other between the two? or both of them are the same in regards to acceleration and deceleration (ACC and CACC) On Tue, Feb 1, 2022 at 1:53 AM Jakob Erdmann <[email protected]> wrote: > The default 'accel' parameter is the same for all models (and this is > reflected in the documentation). > However, the driving dynamics still differ between the models: > - Krauss makes full use of it's default accel and decel values in almost > all traffic situations > - ACC/CACC sometimes accelerate with less than their accel value (thereby > achieving smoother trajectories) > > Am Di., 1.
