Mycity is the safest public transport mode. General safety consideration still are valid. For completeness I add trains (Metrorail) too, but this is only for regular commuters, it is far less safe. If you need to use it, travel the highest class available, or in a group.
Quickfix MyCity :
Mycity has a wonderful planner app, follow this link : VIEW . It lets you enter start and end of your journey, even start or arrival time.
Metrorail :
Metrorail has a planner app too, not as good, but still: VIEW. You have to select first which line you want, then it lets you enter start and end of your yourney, even start or arrival time.
