Traffic, including trucks, is not dsupposed to use the truck apron. The kerb and the raised part warn the trucker who forgets that. The roundabout shown there is a true roundabout. Mini-roundabouts do not exist in Nederland, but we do have fake roundabouts (dot or circle in the middle, possibly raised, no kerb, no roundabout rules. Come to mention it, true roundabouts by themselves do not have special priority rules in Nederland, just the oneway rule indicated by the roundabout traffic signs. However, .priority is almost always indicated by at least shark's teeth. If it isn't, traffic from the right has priority, same as on regular junctions. (We're driving on the right). As for diameters, I think the (minimal) turning circle or maximal rigid vehicle length is what traffic needs. I am not sure that it can be calculated from the diameters of inner centre circle, outer centre circle and circumference of the entire traffic area.
