From page 72...
... Although usually fixed in place, some versions on this barrier can be quickly moved from side-to-side by a special machine to open and close lanes." It is suggested that the term itself be revised to "Concrete Traffic Barrier -- Permanent" to distinguish from the two new terms "temporary work zone concrete barrier-non-moveable" and "temporary work zone concrete barrier-moveable" defined below. Crossover -- the current definition "Area where motor vehicles are permitted to travel across the opposing lanes of traffic or do a U-turn" is potentially confusing, especially in work zones, because it seems to include intersections.
From page 73...
... Stop Signs -- the current definition reads "A six-sided red sign with "STOP" on it, requiring motor vehicles to come to a full stop and look for on-coming traffic before proceeding with caution." Stop signs are required by the MUTCD to include eight sides, and this definition should be revised accordingly. Transition Area -- the current definition "Where lanes are shifted or tapered for lane closure" is incorrect in that the transition area includes any change in the normal traffic pattern, not just lane closures or shifts." It should be revised to read "That part of a work zone located prior to the Activity Area where traffic is moved out of its normal path, such as at a lane closure, lane shift, lane width reduction or median crossover." Work on Shoulder or Median -- the current definition "Type of work zone" should be redefined for clarity to read "Type of work zone in which the activity takes place on a shoulder or median, but not in a travel lane, and no travel lanes are disrupted." Work Zone/Maintenance Equipment -- It was suggested in the discussion of attribute revisions that this term be revised to include equipment and vehicles.
