Hello, by default all vehicles are using the route which would be the fastest in an empty network. To distribute the traffic (without reference to measurement data) sumo supports two approaches - perform traffic assignment ( https://sumo.dlr.de/docs/Demand/Dynamic_User_Assignment.html) - iterative or one-shot - add randomness to the route search: https://sumo.dlr.de/docs/Simulation/Routing.html#randomimzed_travel_times Note, that vehicles may still all use the same route after assignment if it's objectively the fastest (i.e because the roads are mostly empty).
In your case a second effect may be in play: If you load trips between taz direclty into SUMO, the arrival and depart edges will not be distributed over the TAZ. For that you need to run od2trips first. - https://sumo.dlr.de/docs/Definition_of_Vehicles%2C_Vehicle_Types%2C_and_Routes.html#traffic_assignment_zones_taz - https://sumo.dlr.de/docs/Demand/Importing_O/D_Matrices.html regards, Jakob Am Mi., 8.
