Road Traffic Accidents - Castledawson Roundabout

Request
I am looking for road collision figures for the Castledawson roundabout in Magherafelt since the exit for the Cookstown bypass was added in October 2016. I know there have been a lot of collisions that have occurred on this particular roundabout since the extra exit was added for the Cookstown bypass as people aren’t clear about what lane they need to be in for certain exits. There was also a death of a six year old boy who died as a result of a crash on the roundabout last week. The figures don’t need to be of fatalities, just any collisions that have occurred.
