Hello Michael, Thanks for your response! You are right, I want to assign a random traffic flow into the network. The Inlet- and Outlet-edges of the network have defined manually. The traffic flow into the network from the inlet edge, after several time and move, it flow out from an outlet edge. The path of the traffic was based on the network edge connection and when vehicle met an intersection with more branches, it turn randomly.
I have found a solution using: randomTrips.py --weights-prefix, which could achieve this goal. But I met another problem by output the edge data, I want to use this "meandata" to get some edge information: https://sumo.dlr.de/docs/Simulation/Output/Lane-_or_Edge-based_Traffic_Measures.html#meandata_definition But I am confused about how to define it. Should I write it into an additional file and load it with CMD command, such as: randomTrips.py --weights-prefix -a <additionala file> ?

The sources and destinations are given and you want to assign them randomly to each other? Or do you want random volumes between fixed pairs? The routes should be shortest paths or the vehicles should turn randomly (according to given probabilities) in the network but eventually reach a given destination?
