Re: [sumo-user] Emission Class values

Hi,
the answers are inline.

I saw that there is an error percentage associated with each type of emission, I would like to know if this error percentage is relative to reality or is it relative to the old model (HBEFA3).

The error shows how good our (polynomial) fit resembles the original HBEFA4 data. This is just an average over all speeds and accelerations in the range where HBEFA has values, so this does not mean that any standardized driving cycle will show this error.

The second question is about the emission class "Energy", the class for electric vehicles, the noise values for the electric cars simulated are practically the same or even higher than fuel cars, maybe this doesn't make sense.

The noise model currently does not take the propulsion method into account. It is tailored for combustion engines only. I opened an issue here: https://github.com/eclipse/sumo/issues/11767

Best regards,
Michael
