Rod's selection of bus tickets (5)
I believe the answer is:
stick
'rod's' is the definition.
(rod is a type of stick)
'selection of bus tickets' is the wordplay.
'selection of' indicates the answer is hidden within the clue.
'STICK' is hidden within 'bus tickets'.
(Other definitions for stick that I've seen before include "Gear lever; adhere" , "Glue; piece of wood" , "Baton; gum" , "Flak - cling" , "Staff - criticism" .)
