Dangerous traffic jams caused by cars going into Tesco Express Petrol Station

I would be grateful if you could look to do something regarding the cars that queue dangerously to get to Tesco express petrol station. They block the roads and the roundabout, causing complete gridlock. They also try to make a right turn into the petrol station from Redkiln way, this blocking the road each way. I regularly use the road and have seen so many near misses. It is major accident waiting to happen. In the last year it has become substantially worse and more dangerous. Is there anyway you could work with Tesco to make this safer. Maybe install some yellow box junctions with cameras to stop the gridlock.
