Hello, For the generation of vehicles by DFRouter I used the flag "departspeed=max" for a while because of the problems I named in the first mail of this thread. Meanwhile, I have my own script to randomly change a percentage of the created vehicles to a different vehicle type, which also lowers the depart speed if the measured speed is higher than the maximum speed of the vehicle type. So I removed the flag "departspeed=max" because I can use the depart speeds from my detector input. However, now I see that DFRouter creates all vehicles with a depart speed of 36.11, despite the fact that there are varying speeds in the measurement file that DFRouter receives as input. So the input vehicles speeds are ignored by DFRouter. This happens both with sumo 0.20.0 and the svn version of February 20.
