Traffic system continued with fliers close to ground (10)

I believe the answer is:

contraflow

'traffic system' is the definition.

'continued with fliers close to ground' is the wordplay.
'continued' becomes 'cont' (common abbreviation).
'with' says to put letters next to each other.
'fliers' becomes 'raf'.
'close to ground' becomes 'low'.
'cont'+'raf'+'low'='CONTRAFLOW'

I've seen this clue in The Telegraph.
