Dear JakobThanks for the reply.
I would like to know how the gradient is taken into account in the KraussPS model.
However, I can't find any appropriate references in SUMOdocumentation.
If you know of any formulas or references, please let me know.Best regards_______________________________________________2023年6月5日(月) 1:18 Jakob Erdmann <namdre.sumo@xxxxxxxxx>:Of all the carFollowModels in sumo, currently the only ones that takes grade into account are "KraussPS" (which stands for Krauss plus Slope) and "Rail".You could override model accelerations via TraCI using vehicle.getSlope and vehicle.setAccel and vehicle.setDecel (the latter two set upper and lower bounds on acceleration) or you could override an existing model: https://sumo.dlr.de/docs/Developer/How_To/Car-Following_Model.html_______________________________________________Am So., 4.

I have a question about SUMO's vehicle speed.
Is the effect of road grade taken into account in determining the vehicle speed?
(From looking at Krauss' paper on vehicle following models, it does not appear that gradient is taken into account)
Also, is it possible to calculate speeds taking road gradient into account?
Best regards
