If you want put parcelable to intent just add:

intent.putParcelableArrayListExtra("transports", (ArrayList<? extends Parcelable>) arrayListsTransportsForAllStops);

To get this in next activity:

Intent data = getIntent();
List <Transports> result = data.getParcelableArrayListExtra("transports");

You can iterate through ArrayList<Transports> objects in its enclosing ArrayList and for each of this ArrayList<Transports> objects you should use putParcelableArrayListExtra separately using different keys for each of them.
