Hi Gerald, exactly nothing happens along the way hence there is no documentation for this. The speedFactor is picked at vehicle creation and remains constant over the life cycle. Being a unit-less value (typically ~1), it will be applied to every speed limit along the way when computing the maximum desired vehicle speed.
The only way to change vehicle attributes is via TraCI or type-calibrators. A list of everything that can influence vehicle speed is at https://sumo.dlr.de/docs/Simulation/VehicleSpeed.htm regards, Jakob PS: vehicle-class specific speed limits that were discussed in that email have since been implemented (and are strongly recommended when simulating a bimodal speed distribution for trucks and cars).
