I was just asking to see if there is a way to clear the traffic easier & totally get how everyone's safety is paramount.
think if you want to resolve the issue to the point that its safe to have cars an pedestrians leaving en masse at the same time you're looking at making some costly changes to the north west side of the site, the roads and the roundabout.
The club won't be paying for that, doubt the arena would be keen so you're looking to a skint council.
You'd be looking to properly fence off the car parks so pedestrians can't cut through them, I'd get rid of the crowded steps down to the crossing and make a large ramp with a shallow incline (similar to Wembley).
Then remodel the roads so you could make Judds Lane one way in either direction temporarily so when its time to leave all traffic is going away from the ground and remodel the roundabout so you could make it so traffic leaving the ground can turn right onto the A444 (essentially go the wrong way on the roundabout) while pedestrians use the other side of the roundabout.
But thats a lot of, expensive work, so there's zero chance of it happening. Needed it to be better planned out when it was built.
