Jacques Tati's film business (7)

Ross

I believe the answer is:

traffic

I believe this is a double definition.

'jacques tati's film' is the first definition.
(film directed by Jacques Tati)

'business' is the second definition.
(I've seen this before)

(Other definitions for traffic that I've seen before include "Vehicles moving on public highways" , "Sort of light" , "Vehicles collectively" , "Trade illegally" , "Business" .)

I've seen this clue in The Guardian.
