UK roundabouts

Hi, I'm looking for some roundabout assets for my UK fictional routes. The only one I have found that seems to work with traffic enabled is <kuid2:342053:37016:2> DS Road 01 Roundabout - this is what I am looking for but would like a larger version too as this is more of a a mini roundabout. I have found a few bits and pieces on the DLS such as <kuid:243828:100282> C+ RN Rbt Circ Asph 10m dia Type 1 but that is just the centre and I am not sure how to put it together, there are junctions and centres but no way of linking them that I can see.

There is also <kuid2:195357:102313:1> UK Roads 8m - Roundabout but that is the same size as the DS one and doesn't appear to be traffic-enabled.

Any suggestions would be welcome!

I make my own from road splines by mgreen48. I use the pavement on one side spline for the outer lane and use the unmarked spline for the inner lane joining to the outside spline at the end of the junctions.
