| Re: [sumo-user] vehicle mass and loading - emissions |
Hi Natalia, it works here. I changed the vehicle loading to 5000 and the fuel consumption roughly doubled. Which value did you try? It is probably not very sensitive.

That is to say, if I change the value of the vehicle mass/loading (e.g. in PC_G_EU4_PHEMLight.veh) , will I get different emission results (considering that the emission curves will remain the same). >>>>> Also, what does the vehicle loading represent? >>>>> thank you, >>>>> Regards, >>>>> Natalia >>>>> _______________________________________________ >>>>> sumo-user mailing list >>>>> sumo-user@xxxxxxxxxxx >>>>> To change your delivery options, retrieve your password, or unsubscribe from this list, visit >>>>> https://dev.eclipse.org/mailman/listinfo/sumo-user >
