| Re: [sumo-user] HBEFA3 emissions behavior for decelerating vehicles |
Hi Andres, the reason is probably that we do not have data for negative accelerations in the HBEFA case and in our experiments the results came closer to reality with this setting. I think it compensates a little for another bug where the emissions with v=0 are already to high. But yes this is a bug in the model, see https://github.com/DLR-TS/sumo/issues/2110 Best regards, Michael Am 23.01.2018 um 17:37 schrieb Andres Felipe Acosta Gil: > Dear SUMO community. > > We would like to know: why the emissions of decelerating vehicles are > zero instead of something like the emission value of a stopped vehicle? > We noted this behavior in src/utils/emissions/HelpersHBEFA3.h, around > the line 108.
