What the J2735 Standard Says:
In Section 11.8 Lanes, Objects Defined in Intersections and Elsewhere of the J2735 document the following (normative) text is given:
Median Lanes In general, no type of traffic is presumed to occupy and follow a median lane along the described lane path. Median lanes are often crossed by crosswalk lanes, but do not as a rule cross other lane types. Median lanes serve the need to describe the general layout of the intersection and have value in improving the algorithmic ability to project a vehicle’s BSM message with positional measurement biases into the correct lane for traffic control and safety uses. This lane type does not have a movement state associated with it. Information about curb height and other barrier details can be of value to emergency responders in traversing the intersection.

Best Practices and Usage Commentary
Add commentary on how this is to be used and correct any isuse that have come up n practice with others.
If proposed changes or additional items are known, might elect to document them here before TC can consider them, just to have a list. Then again that may be unworkable or SAE may not want it done that way.
