Re: [sumo-user] Most realistic car following model?

Hello Jakob, thank you for your response.

I tried setting lcMacSpeedLatStanding=0, and I am indeed facing a deadlock as mentioned In this issue: https://github.com/eclipse/sumo/issues/3392#issuecomment-902466679 . Is there a way to fix the deadlock issue without manually messing about the lane-changing parameters? Maybe some known set of parameters that generically work for all situations without causing a deadlock while also preventing sliding - I also tried increasing the lcSpeedGainLookahead to no avail!

Sincerely,
Hriday

This is a general issue of SL2015 and not limited to Krauss. You can may be able to prevent sliding by setting lcMacSpeedLatStanding=0

I'd say no. The models were developed/tested for a rather narrow range of applications and are known to behave badly (i.e. collide) outside that range. To learn more, please refer to the publications linked in their documentation.
I you need a model that is more sophisticated than Krauss, take a look at https://sumo.dlr.de/userdoc/Car-Following-Models/EIDM.html

Jakob

Hello,

I have noticed that the Krauss CF model seems to outperform other models like IDM, ACC and CACC in terms of total simulation time for all vehicles to reach the end of their journey. But the SL2015 LC model combined with Krauss CF model makes for some unrealistic lane changing when faced with a blockage in a 2-lane condition (slides laterally to lanes when there's no space to accelerate in front).

Both ACC and CACC seem to be more realistic and intelligent. Are these modelled close to the state-of-the-art systems that self-driving vehicles use currently for cruise control?

Thank you.

Sincerely,
Hriday.
