A new double-lane roundabout has some issues with an offramp being very close to the exits from one side of the roundabout. There have been some safety concerns so I thought I'd look at the system to determine what the problems might be, if any, and to see if there are some viable solutions if some
A new double-lane roundabout has some issues with an offramp being very close to the exits from one side of the roundabout.
There have been some safety concerns so I thought I'd look at the system to determine what the problems might be, if any, and to see if there are some viable solutions if some issues are brought to light.

Rules of roundabouts are:
If in LL, you can turn left or go straight in LL.
If in RL, you can go straight in RL or turn right, exiting in RL.
For all cases, you must indicate asap before exiting but stay in your original chosen lane.
