Hello, the simplest way to define a flow with a given rate is with the <flow> element (fixed and random insertion headways are possible): https://sumo.dlr.de/docs/Definition_of_Vehicles%2C_Vehicle_Types%2C_and_Routes.html#repeated_vehicles_flows
The next step up is to define multiple flows to systematically vary the arrival rate over time. You can use netedit to define traffic (vehicles, trips, flows, ...) graphically: https://sumo.dlr.de/docs/Netedit/ https://sumo.dlr.de/docs/Netedit/editModesDemand.html#vehicle_mode regards, Jakob Am Fr., 7.
