RE: dual protected / permissive left turns
The Highway Capacity Manual (page 10-22)recommends protected left turn phasing if more than a single lane is being provided. I can not recall ever seeing a permissive double left turn lane at a traffic signal.
In Rhode Island we have used opposing protected permissive left turn phasing, but only if a left turn lane is provided.
In the absence of left turn lanes a protected move can only be provided in one direction.

RE: dual protected / permissive left turns
One has been in operation for over 10 years, another for about 2 years and the last two were activated this past January.
We have not had any citizen complaints referenced to this type operation and I am not aware of an accident history that would require modification of the operation.
