I have been told that the staffed and unstaffed gate arms are there for the safety of the golf carts and pedestrians crossing at busy points in the villages where the normal flow of cars would not give carts and pedestrians enough time to safely cross. The gates also allow the drivers of the cars to slow enough to see the crossing traffic. The attendants at the staffed gates should coordinate both types of traffic to keep the intersection safe and flowing. To just wave without checking for slower crossers is careless.
