Hi to all my fellow members

Negotiating a roundabout would seem to have always had it's problems. The solution to a smooth transition through said obstacle is reasonably simple, providing only one vehicle at a time enters. Clearly this can be achieved with the use of TC's on both entrance and exit. The problem arises when there are multiple vehicles either passing onto the roundabout or travelling around the roundabout before exiting.

Having spent a number of hours trying to perfect a solution to this problem I have to admit to defeat. With my solution things seem to work for a period of time but then go completely off the rails, so to speak. My conclusion is to reason that variables and a counter system for each junction are the answer, but I have to say that my attempts, through limited knowledge, to implement these elements has also drawn a blank.

So my question to you all is, "Has anyone solved this issue" and if so would you be so kind as to point me in the right direction.

Apologies, I forgot to attach my attempt thus far.
