I need to set up a random speed distribution among
vehicles in the simulation for every run, I already set the
speedFactor attribute for the vType of vehicles , this is
already generating a mixture of vehicles speed in the
simulation, but on every run the speed don't change.
For example :
I have three vehicles which I want the speed of each to be
in the range 100-120 km/h.
the speedFactor is already generating different speeds in
the range for the 3 vehicles, but on every run of : sumo-gui
-c demo.sumocfg --fcd-output file.xml , the speeds seems to be
the same (if vehicule1 speed is 110km/h it stays like that for
every run).
