In LC2013, the speed is computed by using the safe speed according to the
car-following model and also by extrapolating acceleration.
See
https://github.com/eclipse/sumo/blob/master/src/microsim/lcmodels/MSLCM_LC2013.cpp
lines 1521-1560

In SL2015, there is also an element of averaging such speeds over multiple
time steps.
See
https://github.com/eclipse/sumo/blob/master/src/microsim/lcmodels/MSLCM_SL2015.cpp
lines 1883-1946

Jakob
