Hi, flow definitions are described here: http://sumo-sim.org/userdoc/Definition_of_Vehicles,_Vehicle_Types,_and_Routes.html#Repeated_vehicles except that for router input they do not have route childs but from and to attributes like trips. For the traffic lights I think you misunderstood the documentation, there is usually one traffic light logic per junction but it may be one signal per link, see here: http://sumo-sim.org/userdoc/Simulation/Traffic_Lights.html
