This is usually done by using the duarouter or by just feeding the trips
directly into sumo and let the simulation caluclate the routes. See
https://sumo.dlr.de/docs/Demand/Shortest_or_Optimal_Path_Routing.html

There is traci.route.add function. Furthermore if you give the vehicle a
route consisting of two disconnected edges it will search a route
automatically (much like a trip).

traci.vehicle is an instance of the class traci._vehicle.VehicleDomain,
so for seeing the methods offered by the python traci interface you need
to look into the definition of the VehicleDomain in _vehicle.py. For
calling the methods you refer to traci.vehicle
