While some industry operators have continued to argue that this is not practicable others have
implemented the approach and even improved on it with added productivity gains. Figure B shows an
example of how one operator adapted the concept of exclusion zones around three vehicles where previously
there were three forklifts unloading the vehicles and three drivers standing or moving around next to their
vehicles. Now only one forklift is used to unload the three vehicles, the other two forklifts remain outside the
exclusion zone and shuttle freight to the warehouse. This immediately improved productivity by reducing
turnaround times. However, the change could be combined with a further productivity measure, as the new
traffic management practice facilitated the installing of weigh scales on the edge of the exclusion zone so
that all freight could be weighed as it came off the trucks. The operator’s suspicions of systematic
undercharging of cargo were confirmed; in the first shift alone approximately 12 tons of extra ‘unpaid’
freight was found
