Small roundabout needs signage

In the attached photo you can see a small roundabout. The roundabout has zero signage and is not treated as a roundabout. If you have driven south down Prince Drive and then turned right onto Elizabeth Drive most pass the roundabout on the left hand side and access the southbound side of the A6. However if you turn off the A6 heading south onto Elizabeth Drive you are likely to encounter a car on the wrong side of the road going around the roundabout. So it needs signage to indicate it is a roundabout (if it is) and which way cars should go around it - arrows on the road perhaps. If it is not a round about and cars can go either side then a couple of two way signs would add clarity here. I have observed several "near misses" here recently so it could do with some clarity.
