Pedestrian in public location (11)
I believe the answer is:
commonplace
'pedestrian' is the definition.
(thesaurus)
'public location' is the wordplay.
'public' becomes 'common' ('common' can be similar in meaning to 'public').
'location' becomes 'place' (place is a kind of location).
'common'+'place'='COMMONPLACE'
'in' is the link.
(Other definitions for commonplace that I've seen before include "Not unusual" , "Ordinary, everyday" , "Frequent" .)
