Hello, 1) in your second sumocfg no route file is being loaded and therefore you have no vehicles 2) I recommend that you rebuild your network with the recommend options for importing OSM data: https://sumo.dlr.de/docs/Networks/Import/OpenStreetMap.html#recommended_netconvert_options (alternatively, use osmWebWizard which does this automatically) 3) I recommend that you generate your randomTrips with the option --junction-taz (see https://sumo.dlr.de/docs/Simulation/Turnarounds.html)
