It might be helpful for me (for comparisons across a more diverse set of road networks) to be able to ignore a route that has an erroneous (non-existent) starting or ending edge. No current way to do it when using a route file? I hope I'm not wasting my time trying to put in the trips using traci.vehicle.add() and trapping errors in python with try: except: on that command.
