1. routing by effort is only effort (so the value is 3), however, the travel time is still tracked because you might have defined different effort for different times (i.e. the time to travel by train depends on the schedule and thus waiting time). 2. no. 3. yes. By launching multiple instances of sumo and switching between them. See https://sumo.dlr.de/docs/TraCI/Interfacing_TraCI_from_Python.html#controlling_parallel_simulations_from_the_same_traci_script
Note, that you should achieve a huge speedup in the setEffort part if you use libsumo (https://sumo.dlr.de/docs/Libsumo.html) though this precludes having parallel instances in a single python process.
