Hi Piotr,
thanks for the scenario. The behavior has two different reasons, which
are tracked in the tickets https://github.com/eclipse/sumo/issues/7733
and https://github.com/eclipse/sumo/issues/7734
The main thing is that the internal acceleration value is still less
than 0 even if the printed velocity is already 0 (due to rounding) for
the first ten seconds of the stop. This makes the emission model assume
the vehicle is coasting.

Best regards and thanks for reporting,
Michael
