I'm with Analise on this one.
I haven't transferred at Broadway Junction in more than a decade. But if it were my sister traveling alone at night, and she were not willing to spring for a cab, I would take the A or the E to 14th Street in Manhattan and pick up the L there. Yes, it will add about half an hour to the trip, but I would avoid Broadway Junction late at night.
