It's all down to the autogate system. Previously drivers would go to the port, log their details in the logistics building then go through the border control and park up in the port and wait.
The autogate system knows when the container is arriving and when it's off the vessel and what truck is picking it up. When the drivers arrive now they go to an automated gate, they are only allowed to arrive 20 mins prior to their estimated collection time, otherwise they are turned away to keep their KPI''s down as they use this info to drive trade.
The drivers have to turn round and stack along the back of the maritime building to the strand road entrance (about a mile) once that hits the limit they're straight on to regent road.
The week the new autogate was implemented it went down, totally failed. It was absolute chaos, never seen anything like it. Artic's where driving up and down derby road until the police arrived to take control of traffic management.
This is on the concerns on the table, operation stack on match day would cause havoc and be quite dangerous
